English ivy in need of shade and water in the desert
Janet Baraclough.. expounded:
It may be hard for Americans to imagine this, but there are countless ancient native trees all over the UK, whose individual location and the role they played in history has been recorded for many, many hundreds of years. Trees used as property markers were recorded in the Domesday book in 1086. Far earlier than that, many were protected for their religious significance (particularly, hawthorns and yew). It's not hard for this American to imagine it, I've seen it. One of my fondest memories of my trip to southwestern England was my early AM walk through the New Forest (forgive me, but I think it was somewhere near Tourquay. Being England, of course, the forest was anything but new, it was ancient, the feeling I got while walking through there I doubt I'll ever experience again. Then (my memory is going) I was a a Norman abbey, outside of which was an 1100 year old yew that was hollow in the middle. They kept it short over the centuries by using the branches for arrows. The age of things I saw over there awed me. And I also saw plenty of native plants between the gardens we visited. Seemed a pretty complete ecosystem to me! -- Ann, Gardening in zone 6a Just south of Boston, MA ******************************** |

Oh yes, I forgot.
Its garbage too!!!! Just because it happened many years before you were born, Janet, that doesn't mean it didn't happen. "Janet Baraclough.." wrote in message ... The message m from "Cereus-validus" contains these words: Almost everything that presently grows in England is an "exotic" because the natives had completely decimated the forests and wiped out the original native flora ages ago. Garbage. Janet, Scotland. |

Garbage. Janet, Scotland. It was certainly too sweeping a statement to be less than silly, but I gather the best lumber forests in the UK are today Douglas fir forests from here in the Pacific Northwest, completely naturalized & vastly too large & swift-growing & overshadowing for native trees to survive with the Douglas. You're mistaken. The "lumber forests" in Britain are purpose planted, usually on otherwise treeless hillside. They are predominantly sitka spruce although Douglas fir is also grown. They were mainly planted post ww2, so as they mature for harvest they are shrinking. Those commercial forests are separate from, and don't impinge on, our native woodlands and there isn't a problem with naturalised Douglas firs killing out native woodland. As I recently read a great deal on Douglas firs & a biography of David Douglas himself, I assure you they've been in the UK vastly longer than you seem in your comment allows, & the thing about the Douglas is it will NOT remain in a production forest, which even if it did, production forests themselves displace actual complex ecosystems. The tree is after all named for a Scot, & David Douglas, who died in 1834, lived to see his own trees big enough for harvests. His trees like ones planted in New Zealand following his UK example quickly naturalized, because that's what they're great at doing. Douglas did also plant the Sitka Spruce, so unless his ghost did that post-WWII, you're off by well over a century. What really happened post-WWII is the already decimated ancient forests were cut down entirely. More of them than not. In twenty years all the damage that had been done in five centuries before was exceeded. And it is only quite recently that "back from the brink" projects have saved some little bits of what little remains, & replanted what was long removed, whereever possible. And many forests that were completely eradicated through the past 600 years have had restoration within the last 125 years, but largely of foreign species that at best approximated the originals. There are plenty of ancient surviving woodlands, far older than 600 years; try a websearch on the Caledonian Forest. The Great Caledonian was so nearly destroyed that it became known as "the remnant pine forest." Tim Clifford of the Caledonian Partnership said the good fate of the Caledonian wasn't assured until the present decade, & still requires good watchdogs. An assessment only five years ago was that the Caledonian was "very far removed from the romantic ideal," the Native Pinewoods Scheme having only begun in 1989 and not falling swiftly behind the curve for its whole first decade before the Caledonian Partnership and Trees for Life were formed. The modern attempt to restore its former biodiversity is laudable to extreme, & nice that some old things weren't taken in a very few central parts, but being forested since ancient times is even so not what you are taking it mean. The Caledonian Forest's MODERN restoration is an in-progress bit of heroism, but even if it weren't nearly lost, given that the lifespan of a Caledonian pine is 200 to 350 years, & the Caledonian's birches are vastly younger than that, your "far older than 600 years" doesn't wash. The RECORD age of any living Caledonian pine is 550 years from a remote glen -- far older than they would ordinarily live, but still shy of your "far older than 600 years" even for the rare exceptions -- though compared to what England boasts, Scottish trees are up there in age. On the other hand we must not mistake the phrase "Ancient forest" for "Ancient trees," but more importantly, don't mistake "Anent trees" for "biodiversity." One old Yew in a churchyard is not a healthy ecosystem by itself, & the fact the Great Caeldonian has very little in it older than a century -- a few of the oldest a scant 300 years -- is not the measure of its health. It sounds like its biodiversity is being restored in vast stretches of the new Great Caledonian, & that's a great deal more important than any pretences of the trees themselves being ancient -- health & old age are not necessarily the same thing. Then again, the reason it is important to identify the oldest Caledonians is so they can be cloned. The Scottish pine is a subspecies, but only the oldest ones are not hybridized! Less than 100 old Caledonians have been identified as pure stock (amidst which is the one gauged to be 550 years old, two centuries longer than their expected lifespans, & the real hope for the survival of the subspecies, because Alan Fletcher trained a group of advocates with the Forestry Commission to produce young replicas from this old genetic stock -- the "merely" 200 year old trees being all genetically polluted. So the only reason the TRULY native species isn't doomed to extinction in the near future is because of modern cloning techniques & the survival of 100 trees older than the expected lifespan in an obscure glen. Such heroic efforts are NOT being made for everything, & what I outlined remains largely true -- even in places where biodiversity exists, truly NATIVE species are being displaced by invaders or hybridized with introduced species -- so much so that even pure Caledonian pines appear to have fallen down to 100 in number -- even in your "ancient" forest where one would have expected an exception to such a rule. This certainly HAD to change the dynamics of the forest floor, pollinator-behavior & survival, when the giant plants in an ecosystem are completely changed, very little that is smaller is going to stay the same. Or the English Bluebell that two centuries ago was famed for its overpowering scent of balsam & cinnamon is today completely scentless completely untrue from having become thoroughly hybridized with the always-scentless Spanish squill, so that a pure native scilla with its former redolence is apparently extinct. That is mistaken. Yes, there are recent concerns about hybridisation with the Spanish bluebell,(a garden escape) but there are still thousands of wild places far from the curse of where the pure English form is undiluted and as powerfully scented as ever. If it is not yet universally true, & there are some out of out of the wy places, say, in Wales, where the redolence of scilla still fills the air, then great. Ban the Spanish the hybridization is final & complete then! But the anishing scent is written about in MANY articles; protected expanses of bluebells in Sheffield are reportedly hybrids without scent, & no less than the UK Wildlife Trust has sent out the alarm about few if any English Bluebells being pure English Bluebells. Same with hedge hawthorn, today so hybridized with species from all over the northern hemisphere that whatever the purely native English hawthorn was like two or three centuries ago is no longer quite known. Try looking up the age of the Glastonbury Thorn :-) It may be hard for Americans to imagine this, but there are countless ancient native trees all over the UK, whose individual location and the role they played in history has been recorded for many, many hundreds of years. Trees used as property markers were recorded in the Domesday book in 1086. Far earlier than that, many were protected for their religious significance (particularly, hawthorns and yew). In other words, there's no problem identifying the DNA of ancient native British species. We've either got a living example, or we've got buildings, furniture etc made from their wood, (and dated) for matching purposes. There are scores if not hundreds of forestry and wildflower nurseries which supply stock with DNA-proven native provenance. I trust you put the Glastonbury Thorn in front of a smily emoticon because you well knew it was already a big tourist fraud before Cromwell cut it down, & it became doubly a fraud when it was afterword pretended to have been magically resurged. British legends are wonderful things. They're not comparable to DNA. But if we are to accept myths for science, then according to the same myth of the Thorn's extravagant old age, it never was a native species ever but was brought by sea from afar, so if it really had lived for 2000 years and seeded all of Glastonberry, then there's an invasive non-native problem for ya! Seems every ten miles there's a church boasting the oldest tree in the UK in its churchyard, often something like an oak that is incapable of living so long, & the most "credible" of these many-centuries or millenia-old trees are at best the great-great-great descendant of the trees their caretakers pretend them to be. Such legends are lovely & to be encouraged, though completely unrelated to science & ecology & the continuance of a diverse ecosystem. When one looks for scientifically accredited ages, they shrink dramatically, but even myth-makers can claim without cracking a smile that the oldest tree in England is a 300 year old plane tree (I've hugged trees three times that age right here in my county), while the ones pretending to be much older rely on records of how long certain stories of them were told rather than on how many rings they have. Happily some trees in Scotland really are old even if the English ones are frauds, & I'm betting more than a few Scots are glad to know it. The oldest tree in Scotland, the Fortingill Yew, was pretended by generations of caretakers to be 5,000 years old. It's not, of course. But how jolly the Forestry Commission COULD show it was decently old, if sickly, at 1,760 years -- (since it was dated, the church has reportedly taken to saying it is "only" 3,000 years old since the 5,000 year date was disproven; strange they still can't bare the truth, that the Forestry Commission was being pro-tourism to permit any age to it at all, it's really just a young thing growing out of the dead grandparent, & it was the dead tree that could be dated to 1,760 years. If any ancient forests REALLY remained in England, these kinds of fibs, exaggerations, & reliance on mythology where science fails, wouldn't be essential. I only have to go for a walk to find trees older than the oldest ones that are tourist treats in your beloved isles -- but it may not always be so, as our president only this past week changed a few regulations so that more of the Olympic rainforest could be cut down -- the youngest of those trees being two or three centuries, & the ones that the lumberjacks are going to get are over a thousand). But even if King John's Oak hadn't been a fraud, even if the Glastonbury Thorn hadn't been two times dead in modern history, even if the yew pretending to be 'the oldest living tree on earth' weren't but a young tree growing from a dead one -- even if the legends of ancientness weren't in the main all fables, such random old survivors would not an ecosystem make. Closer to reality is the history of Aster Wood which vanished slowly from the Victorian era to the 1940s, when the very last of it was clearcut for firewood. It's now an expanse of bushes at least, & a few trees coming back, though not far from it is an entirely new woods that is supposed to look pretty old though nothing in it is older than about 50 years. I read an article about English forest-edge ecosystems which once had a wide array of native shrubs that are today dominated by century-old Pontus rhododendrons. Rhododendron ponticum is indeed a pest, but only in a limited habitat niche in parts of the wetter, milder acid-soil west of the UK. Not in the drier colder east, or limestone areas etc. You seem not to to be taking into consideration how that ecosystems are finite. If something takes over "the wetter, milder acid-soil west of the UK" then native plants that required that environment did not magically travel to the drier colder east & survive. The drier east has entirely different invasives whic have displaced entirely different native plants, or hybridized with them so that truly distinct races of plants disappear. Similarly, the fact that one or two ancient forests belonging to Kings were preserved exclusively for Kings to hunt in is very nice for those forests, but they too are finite ecosystems, do not represent all the species that grew north & south, east & west, & are have a lord's plenty of species from three continents invading them. Even in ponticum-territory, not all woodlands are affected. Native forest-edge and forest-understory still thrives in all parts of britain. I hope you're right, but you seem to have a glowy impression of things which your Wildlife Trust does not always share. It's the same story as all over the world, except the UK is so much more finite for being islands, so that like other island ecosystems it was always more at risk. The only thing wrong with that is the mistaken premise that Britain has lost its ancient flora and ecology; that isn't the case. I'm simply astonished that two Americans who have a deep interest in botany and ecology, should both have the extraordinarily inaccurate impression that British native wild flora and ancient ecosystems are a thing of the past, dead and gone. Far from it. Well, all I can say is that it is English writers who have published articles about the loss of the scent in the English Bluebell -- if it's untrue in some places that is good (too bad it remains untrue of any cultivated ones), but it's a well-documented & often written-of problem always presented as a tragedy. And as you didn't know how long the Douglas & Sitka firs have been in the UK, with the Douglas in particular naturalized apart from production forests & in no location, production or otherwise, permitting a native ecosystem co-exist with it, then I'm not 100% certain you know more about it than your own complaining ecologists. If your best examples are a hawthorn that is only a tourist myth in age, & the lovely Caledonian only now BEGINNING to be repopulated due to heroic efforts to recover the native subspecies, well, my parallel to your astonishment would be "I'm simply astonished that a Scot wouldn't know the Caledonian pine came within 100 trees of not existing as a separate subspecies." Except I'm not astonished; practically at my own back door thousand-years-old firs are being removed from "protected" lands because the President said it was okay, & if any gardener on my street knows about that, it's because I informed them. For the UK though, the lists of still-endangered UK species is long enough that your insistance that it isn't true is just flat-out wishful thinking -- but whether that really indicates a larger percentage of the overall flora is gone than in most other places I wouldn't want to swear is true, only that your rose-tinted glasses are causing you to miss a few bits of reality. In the USA we're losing more species every year, and our gardens are hybridizing with the forests just as avidly as began in the UK at least 500 years sooner than here, & many of our commonest weeds are from Europe or Central Asia. So I wouldn't pretend a better condition here -- but your rose colored glasses for the UK seem to be blinding! -paggers Janet. -- "Of what are you afraid, my child?" inquired the kindly teacher.

And as you didn't know how long the Douglas & Sitka firs have been in the UK, with the Douglas in particular naturalized apart from production forests & in no location, production or otherwise, permitting a native ecosystem co-exist with it, then I'm not 100% certain you know more about it than your own complaining ecologists. If your best examples are a hawthorn that is only a tourist myth in age, & the lovely Caledonian only now BEGINNING to be repopulated due to heroic efforts to recover the native subspecies, well, my parallel to your astonishment would be "I'm simply astonished that a Scot wouldn't know the Caledonian pine came within 100 trees of not existing as a separate subspecies." Except I'm not astonished; practically at my own back door thousand-years-old firs are being removed from "protected" lands because the President said it was okay, & if any gardener on my street knows about that, it's because I informed them. For the UK though, the lists of still-endangered UK species is long enough that your insistance that it isn't true is just flat-out wishful thinking -- but whether that really indicates a larger percentage of the overall flora is gone than in most other places I wouldn't want to swear is true, only that your rose-tinted glasses are causing you to miss a few bits of reality. In the USA we're losing more species every year, and our gardens are hybridizing with the forests just as avidly as began in the UK at least 500 years sooner than here, & many of our commonest weeds are from Europe or Central Asia. So I wouldn't pretend a better condition here -- but your rose colored glasses for the UK seem to be blinding! -paggers Janet. -- "Of what are you afraid, my child?" inquired the kindly teacher.

Garbage. Janet, Scotland. It was certainly too sweeping a statement to be less than silly, but I gather the best lumber forests in the UK are today Douglas fir forests from here in the Pacific Northwest, completely naturalized & vastly too large & swift-growing & overshadowing for native trees to survive with the Douglas. You're mistaken. The "lumber forests" in Britain are purpose planted, usually on otherwise treeless hillside. They are predominantly sitka spruce although Douglas fir is also grown. They were mainly planted post ww2, so as they mature for harvest they are shrinking. Those commercial forests are separate from, and don't impinge on, our native woodlands and there isn't a problem with naturalised Douglas firs killing out native woodland. As I recently read a great deal on Douglas firs & a biography of David Douglas himself, I assure you they've been in the UK vastly longer than you seem in your comment allows, & the thing about the Douglas is it will NOT remain in a production forest, which even if it did, production forests themselves displace actual complex ecosystems. The tree is after all named for a Scot, & David Douglas, who died in 1834, lived to see his own trees big enough for harvests. His trees like ones planted in New Zealand following his UK example quickly naturalized, because that's what they're great at doing. Douglas did also plant the Sitka Spruce, so unless his ghost did that post-WWII, you're off by well over a century. What really happened post-WWII is the already decimated ancient forests were cut down entirely. More of them than not. In twenty years all the damage that had been done in five centuries before was exceeded. And it is only quite recently that "back from the brink" projects have saved some little bits of what little remains, & replanted what was long removed, whereever possible. And many forests that were completely eradicated through the past 600 years have had restoration within the last 125 years, but largely of foreign species that at best approximated the originals. There are plenty of ancient surviving woodlands, far older than 600 years; try a websearch on the Caledonian Forest. The Great Caledonian was so nearly destroyed that it became known as "the remnant pine forest." Tim Clifford of the Caledonian Partnership said the good fate of the Caledonian wasn't assured until the present decade, & still requires good watchdogs. An assessment only five years ago was that the Caledonian was "very far removed from the romantic ideal," the Native Pinewoods Scheme having only begun in 1989 and not falling swiftly behind the curve for its whole first decade before the Caledonian Partnership and Trees for Life were formed. The modern attempt to restore its former biodiversity is laudable to extreme, & nice that some old things weren't taken in a very few central parts, but being forested since ancient times is even so not what you are taking it mean. The Caledonian Forest's MODERN restoration is an in-progress bit of heroism, but even if it weren't nearly lost, given that the lifespan of a Caledonian pine is 200 to 350 years, & the Caledonian's birches are vastly younger than that, your "far older than 600 years" doesn't wash. The RECORD age of any living Caledonian pine is 550 years from a remote glen -- far older than they would ordinarily live, but still shy of your "far older than 600 years" even for the rare exceptions -- though compared to what England boasts, Scottish trees are up there in age. On the other hand we must not mistake the phrase "Ancient forest" for "Ancient trees," but more importantly, don't mistake "Anent trees" for "biodiversity." One old Yew in a churchyard is not a healthy ecosystem by itself, & the fact the Great Caeldonian has very little in it older than a century -- a few of the oldest a scant 300 years -- is not the measure of its health. It sounds like its biodiversity is being restored in vast stretches of the new Great Caledonian, & that's a great deal more important than any pretences of the trees themselves being ancient -- health & old age are not necessarily the same thing. Then again, the reason it is important to identify the oldest Caledonians is so they can be cloned. The Scottish pine is a subspecies, but only the oldest ones are not hybridized! Less than 100 old Caledonians have been identified as pure stock (amidst which is the one gauged to be 550 years old, two centuries longer than their expected lifespans, & the real hope for the survival of the subspecies, because Alan Fletcher trained a group of advocates with the Forestry Commission to produce young replicas from this old genetic stock -- the "merely" 200 year old trees being all genetically polluted. So the only reason the TRULY native species isn't doomed to extinction in the near future is because of modern cloning techniques & the survival of 100 trees older than the expected lifespan in an obscure glen. Such heroic efforts are NOT being made for everything, & what I outlined remains largely true -- even in places where biodiversity exists, truly NATIVE species are being displaced by invaders or hybridized with introduced species -- so much so that even pure Caledonian pines appear to have fallen down to 100 in number -- even in your "ancient" forest where one would have expected an exception to such a rule. This certainly HAD to change the dynamics of the forest floor, pollinator-behavior & survival, when the giant plants in an ecosystem are completely changed, very little that is smaller is going to stay the same. Or the English Bluebell that two centuries ago was famed for its overpowering scent of balsam & cinnamon is today completely scentless completely untrue from having become thoroughly hybridized with the always-scentless Spanish squill, so that a pure native scilla with its former redolence is apparently extinct. That is mistaken. Yes, there are recent concerns about hybridisation with the Spanish bluebell,(a garden escape) but there are still thousands of wild places far from the curse of where the pure English form is undiluted and as powerfully scented as ever. If it is not yet universally true, & there are some out of out of the wy places, say, in Wales, where the redolence of scilla still fills the air, then great. Ban the Spanish the hybridization is final & complete then! But the anishing scent is written about in MANY articles; protected expanses of bluebells in Sheffield are reportedly hybrids without scent, & no less than the UK Wildlife Trust has sent out the alarm about few if any English Bluebells being pure English Bluebells. Same with hedge hawthorn, today so hybridized with species from all over the northern hemisphere that whatever the purely native English hawthorn was like two or three centuries ago is no longer quite known. Try looking up the age of the Glastonbury Thorn :-) It may be hard for Americans to imagine this, but there are countless ancient native trees all over the UK, whose individual location and the role they played in history has been recorded for many, many hundreds of years. Trees used as property markers were recorded in the Domesday book in 1086. Far earlier than that, many were protected for their religious significance (particularly, hawthorns and yew). In other words, there's no problem identifying the DNA of ancient native British species. We've either got a living example, or we've got buildings, furniture etc made from their wood, (and dated) for matching purposes. There are scores if not hundreds of forestry and wildflower nurseries which supply stock with DNA-proven native provenance. I trust you put the Glastonbury Thorn in front of a smily emoticon because you well knew it was already a big tourist fraud before Cromwell cut it down, & it became doubly a fraud when it was afterword pretended to have been magically resurged. British legends are wonderful things. They're not comparable to DNA. But if we are to accept myths for science, then according to the same myth of the Thorn's extravagant old age, it never was a native species ever but was brought by sea from afar, so if it really had lived for 2000 years and seeded all of Glastonberry, then there's an invasive non-native problem for ya! Seems every ten miles there's a church boasting the oldest tree in the UK in its churchyard, often something like an oak that is incapable of living so long, & the most "credible" of these many-centuries or millenia-old trees are at best the great-great-great descendant of the trees their caretakers pretend them to be. Such legends are lovely & to be encouraged, though completely unrelated to science & ecology & the continuance of a diverse ecosystem. When one looks for scientifically accredited ages, they shrink dramatically, but even myth-makers can claim without cracking a smile that the oldest tree in England is a 300 year old plane tree (I've hugged trees three times that age right here in my county), while the ones pretending to be much older rely on records of how long certain stories of them were told rather than on how many rings they have. Happily some trees in Scotland really are old even if the English ones are frauds, & I'm betting more than a few Scots are glad to know it. The oldest tree in Scotland, the Fortingill Yew, was pretended by generations of caretakers to be 5,000 years old. It's not, of course. But how jolly the Forestry Commission COULD show it was decently old, if sickly, at 1,760 years -- (since it was dated, the church has reportedly taken to saying it is "only" 3,000 years old since the 5,000 year date was disproven; strange they still can't bare the truth, that the Forestry Commission was being pro-tourism to permit any age to it at all, it's really just a young thing growing out of the dead grandparent, & it was the dead tree that could be dated to 1,760 years. If any ancient forests REALLY remained in England, these kinds of fibs, exaggerations, & reliance on mythology where science fails, wouldn't be essential. I only have to go for a walk to find trees older than the oldest ones that are tourist treats in your beloved isles -- but it may not always be so, as our president only this past week changed a few regulations so that more of the Olympic rainforest could be cut down -- the youngest of those trees being two or three centuries, & the ones that the lumberjacks are going to get are over a thousand). But even if King John's Oak hadn't been a fraud, even if the Glastonbury Thorn hadn't been two times dead in modern history, even if the yew pretending to be 'the oldest living tree on earth' weren't but a young tree growing from a dead one -- even if the legends of ancientness weren't in the main all fables, such random old survivors would not an ecosystem make. Closer to reality is the history of Aster Wood which vanished slowly from the Victorian era to the 1940s, when the very last of it was clearcut for firewood. It's now an expanse of bushes at least, & a few trees coming back, though not far from it is an entirely new woods that is supposed to look pretty old though nothing in it is older than about 50 years. I read an article about English forest-edge ecosystems which once had a wide array of native shrubs that are today dominated by century-old Pontus rhododendrons. Rhododendron ponticum is indeed a pest, but only in a limited habitat niche in parts of the wetter, milder acid-soil west of the UK. Not in the drier colder east, or limestone areas etc. You seem not to to be taking into consideration how that ecosystems are finite. If something takes over "the wetter, milder acid-soil west of the UK" then native plants that required that environment did not magically travel to the drier colder east & survive. The drier east has entirely different invasives whic have displaced entirely different native plants, or hybridized with them so that truly distinct races of plants disappear. Similarly, the fact that one or two ancient forests belonging to Kings were preserved exclusively for Kings to hunt in is very nice for those forests, but they too are finite ecosystems, do not represent all the species that grew north & south, east & west, & are have a lord's plenty of species from three continents invading them. Even in ponticum-territory, not all woodlands are affected. Native forest-edge and forest-understory still thrives in all parts of britain. I hope you're right, but you seem to have a glowy impression of things which your Wildlife Trust does not always share. It's the same story as all over the world, except the UK is so much more finite for being islands, so that like other island ecosystems it was always more at risk. The only thing wrong with that is the mistaken premise that Britain has lost its ancient flora and ecology; that isn't the case. I'm simply astonished that two Americans who have a deep interest in botany and ecology, should both have the extraordinarily inaccurate impression that British native wild flora and ancient ecosystems are a thing of the past, dead and gone. Far from it. Well, all I can say is that it is English writers who have published articles about the loss of the scent in the English Bluebell -- if it's untrue in some places that is good (too bad it remains untrue of any cultivated ones), but it's a well-documented & often written-of problem always presented as a tragedy.

English ivy in need of shade and water in the desert
A quick search revealed that there are a still a few remaining species of
flowering plants endemic to the British islands and nowhere else but most if not all of them are on the verge of extinction by being overrun by introduced weedy species and destruction of habitat. http://www.nhm.ac.uk/science/projects/fff/ChekEnds.htm Note that Sedum anglicum is not on the list because despite the species epithet, it was originally introduced from Scandinavia long ago.

As I recently read a great deal on Douglas firs & a biography of David Douglas himself, I assure you they've been in the UK vastly longer than you seem in your comment allows, & the thing about the Douglas is it will NOT remain in a production forest, which even if it did, production forests themselves displace actual complex ecosystems. The tree is after all named for a Scot, & David Douglas, who died in 1834, lived to see his own trees big enough for harvests. His trees like ones planted in New Zealand following his UK example quickly naturalized, because that's what they're great at doing. Douglas did also plant the Sitka Spruce, so unless his ghost did that post-WWII, you're off by well over a century. What really happened post-WWII is the already decimated ancient forests were cut down entirely. More of them than not. In twenty years all the damage that had been done in five centuries before was exceeded. And it is only quite recently that "back from the brink" projects have saved some little bits of what little remains, & replanted what was long removed, whereever possible. And many forests that were completely eradicated through the past 600 years have had restoration within the last 125 years, but largely of foreign species that at best approximated the originals. There are plenty of ancient surviving woodlands, far older than 600 years; try a websearch on the Caledonian Forest. The Great Caledonian was so nearly destroyed that it became known as "the remnant pine forest." Tim Clifford of the Caledonian Partnership said the good fate of the Caledonian wasn't assured until the present decade, & still requires good watchdogs. An assessment only five years ago was that the Caledonian was "very far removed from the romantic ideal," the Native Pinewoods Scheme having only begun in 1989 and not falling swiftly behind the curve for its whole first decade before the Caledonian Partnership and Trees for Life were formed. The modern attempt to restore its former biodiversity is laudable to extreme, & nice that some old things weren't taken in a very few central parts, but being forested since ancient times is even so not what you are taking it mean. The Caledonian Forest's MODERN restoration is an in-progress bit of heroism, but even if it weren't nearly lost, given that the lifespan of a Caledonian pine is 200 to 350 years, & the Caledonian's birches are vastly younger than that, your "far older than 600 years" doesn't wash. The RECORD age of any living Caledonian pine is 550 years from a remote glen -- far older than they would ordinarily live, but still shy of your "far older than 600 years" even for the rare exceptions -- though compared to what England boasts, Scottish trees are up there in age. On the other hand we must not mistake the phrase "Ancient forest" for "Ancient trees," but more importantly, don't mistake "Anent trees" for "biodiversity." One old Yew in a churchyard is not a healthy ecosystem by itself, & the fact the Great Caeldonian has very little in it older than a century -- a few of the oldest a scant 300 years -- is not the measure of its health. It sounds like its biodiversity is being restored in vast stretches of the new Great Caledonian, & that's a great deal more important than any pretences of the trees themselves being ancient -- health & old age are not necessarily the same thing. Then again, the reason it is important to identify the oldest Caledonians is so they can be cloned. The Scottish pine is a subspecies, but only the oldest ones are not hybridized! Less than 100 old Caledonians have been identified as pure stock (amidst which is the one gauged to be 550 years old, two centuries longer than their expected lifespans, & the real hope for the survival of the subspecies, because Alan Fletcher trained a group of advocates with the Forestry Commission to produce young replicas from this old genetic stock -- the "merely" 200 year old trees being all genetically polluted. So the only reason the TRULY native species isn't doomed to extinction in the near future is because of modern cloning techniques & the survival of 100 trees older than the expected lifespan in an obscure glen. Such heroic efforts are NOT being made for everything, & what I outlined remains largely true -- even in places where biodiversity exists, truly NATIVE species are being displaced by invaders or hybridized with introduced species -- so much so that even pure Caledonian pines appear to have fallen down to 100 in number -- even in your "ancient" forest where one would have expected an exception to such a rule. This certainly HAD to change the dynamics of the forest floor, pollinator-behavior & survival, when the giant plants in an ecosystem are completely changed, very little that is smaller is going to stay the same. Or the English Bluebell that two centuries ago was famed for its overpowering scent of balsam & cinnamon is today completely scentless completely untrue from having become thoroughly hybridized with the always-scentless Spanish squill, so that a pure native scilla with its former redolence is apparently extinct. That is mistaken. Yes, there are recent concerns about hybridisation with the Spanish bluebell,(a garden escape) but there are still thousands of wild places far from the curse of where the pure English form is undiluted and as powerfully scented as ever. If it is not yet universally true, & there are some out of out of the wy places, say, in Wales, where the redolence of scilla still fills the air, then great. Ban the Spanish the hybridization is final & complete then! But the anishing scent is written about in MANY articles; protected expanses of bluebells in Sheffield are reportedly hybrids without scent, & no less than the UK Wildlife Trust has sent out the alarm about few if any English Bluebells being pure English Bluebells. Same with hedge hawthorn, today so hybridized with species from all over the northern hemisphere that whatever the purely native English hawthorn was like two or three centuries ago is no longer quite known. Try looking up the age of the Glastonbury Thorn :-) It may be hard for Americans to imagine this, but there are countless ancient native trees all over the UK, whose individual location and the role they played in history has been recorded for many, many hundreds of years. Trees used as property markers were recorded in the Domesday book in 1086. Far earlier than that, many were protected for their religious significance (particularly, hawthorns and yew). In other words, there's no problem identifying the DNA of ancient native British species. We've either got a living example, or we've got buildings, furniture etc made from their wood, (and dated) for matching purposes. There are scores if not hundreds of forestry and wildflower nurseries which supply stock with DNA-proven native provenance. I trust you put the Glastonbury Thorn in front of a smily emoticon because you well knew it was already a big tourist fraud before Cromwell cut it down, & it became doubly a fraud when it was afterword pretended to have been magically resurged. British legends are wonderful things. They're not comparable to DNA. But if we are to accept myths for science, then according to the same myth of the Thorn's extravagant old age, it never was a native species ever but was brought by sea from afar, so if it really had lived for 2000 years and seeded all of Glastonberry, then there's an invasive non-native problem for ya! Seems every ten miles there's a church boasting the oldest tree in the UK in its churchyard, often something like an oak that is incapable of living so long, & the most "credible" of these many-centuries or millenia-old trees are at best the great-great-great descendant of the trees their caretakers pretend them to be. Such legends are lovely & to be encouraged, though completely unrelated to science & ecology & the continuance of a diverse ecosystem. When one looks for scientifically accredited ages, they shrink dramatically, but even myth-makers can claim without cracking a smile that the oldest tree in England is a 300 year old plane tree (I've hugged trees three times that age right here in my county), while the ones pretending to be much older rely on records of how long certain stories of them were told rather than on how many rings they have. Happily some trees in Scotland really are old even if the English ones are frauds, & I'm betting more than a few Scots are glad to know it. The oldest tree in Scotland, the Fortingill Yew, was pretended by generations of caretakers to be 5,000 years old. It's not, of course. But how jolly the Forestry Commission COULD show it was decently old, if sickly, at 1,760 years -- (since it was dated, the church has reportedly taken to saying it is "only" 3,000 years old since the 5,000 year date was disproven; strange they still can't bare the truth, that the Forestry Commission was being pro-tourism to permit any age to it at all, it's really just a young thing growing out of the dead grandparent, & it was the dead tree that could be dated to 1,760 years. If any ancient forests REALLY remained in England, these kinds of fibs, exaggerations, & reliance on mythology where science fails, wouldn't be essential. I only have to go for a walk to find trees older than the oldest ones that are tourist treats in your beloved isles -- but it may not always be so, as our president only this past week changed a few regulations so that more of the Olympic rainforest could be cut down -- the youngest of those trees being two or three centuries, & the ones that the lumberjacks are going to get are over a thousand). But even if King John's Oak hadn't been a fraud, even if the Glastonbury Thorn hadn't been two times dead in modern history, even if the yew pretending to be 'the oldest living tree on earth' weren't but a young tree growing from a dead one -- even if the legends of ancientness weren't in the main all fables, such random old survivors would not an ecosystem make. Closer to reality is the history of Aster Wood which vanished slowly from the Victorian era to the 1940s, when the very last of it was clearcut for firewood. It's now an expanse of bushes at least, & a few trees coming back, though not far from it is an entirely new woods that is supposed to look pretty old though nothing in it is older than about 50 years. I read an article about English forest-edge ecosystems which once had a wide array of native shrubs that are today dominated by century-old Pontus rhododendrons. Rhododendron ponticum is indeed a pest, but only in a limited habitat niche in parts of the wetter, milder acid-soil west of the UK. Not in the drier colder east, or limestone areas etc. You seem not to to be taking into consideration how that ecosystems are finite. If something takes over "the wetter, milder acid-soil west of the UK" then native plants that required that environment did not magically travel to the drier colder east & survive. The drier east has entirely different invasives whic have displaced entirely different native plants, or hybridized with them so that truly distinct races of plants disappear. Similarly, the fact that one or two ancient forests belonging to Kings were preserved exclusively for Kings to hunt in is very nice for those forests, but they too are finite ecosystems, do not represent all the species that grew north & south, east & west, & are have a lord's plenty of species from three continents invading them. Even in ponticum-territory, not all woodlands are affected. Native forest-edge and forest-understory still thrives in all parts of britain. I hope you're right, but you seem to have a glowy impression of things which your Wildlife Trust does not always share. It's the same story as all over the world, except the UK is so much more finite for being islands, so that like other island ecosystems it was always more at risk. The only thing wrong with that is the mistaken premise that Britain has lost its ancient flora and ecology; that isn't the case. I'm simply astonished that two Americans who have a deep interest in botany and ecology, should both have the extraordinarily inaccurate impression that British native wild flora and ancient ecosystems are a thing of the past, dead and gone. Far from it. Well, all I can say is that it is English writers who have published articles about the loss of the scent in the English Bluebell -- if it's untrue in some places that is good (too bad it remains untrue of any cultivated ones), but it's a well-documented & often written-of problem always presented as a tragedy. And as you didn't know how long the Douglas & Sitka firs have been in the UK, with the Douglas in particular naturalized apart from production forests & in no location, production or otherwise, permitting a native ecosystem co-exist with it, then I'm not 100% certain you know more about it than your own complaining ecologists. If your best examples are a hawthorn that is only a tourist myth in age, & the lovely Caledonian only now BEGINNING to be repopulated due to heroic efforts to recover the native subspecies, well, my parallel to your astonishment would be "I'm simply astonished that a Scot wouldn't know the Caledonian pine came within 100 trees of not existing as a separate subspecies." Except I'm not astonished; practically at my own back door thousand-years-old firs are being removed from "protected" lands because the President said it was okay, & if any gardener on my street knows about that, it's because I informed them. For the UK though, the lists of still-endangered UK species is long enough that your insistance that it isn't true is just flat-out wishful thinking -- but whether that really indicates a larger percentage of the overall flora is gone than in most other places I wouldn't want to swear is true, only that your rose-tinted glasses are causing you to miss a few bits of reality. In the USA we're losing more species every year, and our gardens are hybridizing with the forests just as avidly as began in the UK at least 500 years sooner than here, & many of our commonest weeds are from Europe or Central Asia. So I wouldn't pretend a better condition here -- but your rose colored glasses for the UK seem to be blinding! -paggers Janet. -- "Of what are you afraid, my child?" inquired the kindly teacher.

English ivy in need of shade and water in the desert
The message m
from "Cereus-validus" contains these words: A quick search revealed that there are a still a few remaining species of flowering plants endemic to the British islands and nowhere else but most if not all of them are on the verge of extinction by being overrun by introduced weedy species and destruction of habitat. That is considerably different from your earlier claim that Almost everything that presently grows in England is an "exotic" because the natives had completely decimated the forests and wiped out the original native flora ages ago. Now all you need do is change your revised version to "there are many remaining British wild species" and "some, (not all, not most) of them are on the verge of extinction" and you'd alsmost sound as if you knew something about the subject.

Sorry little Broccoli,
I still stand by both my original statement as well as my more recent one. The very few remaining endemic species are but a trifle compared to what must have resided on the islands before man took over, cut down the forests, radically modified the environment and introduced many exotic alien species for food, their gardens and many weed species along with them. You carry on as if I am holding you responsible for what your ancestors did. If you have a problem with that, you are a real pip. Its happened and there is nothing you can about it. Extinction is forever! "Janet Baraclough.." wrote in message ...

English ivy in need of shade and water in the desert
I did think I was agreeing with Cereus-validus. Absit invidia. Personally I
did garden, for fifteen years, in a desert climate in the Canary Islands where rain was something that fell elsewhere. I still have the garden and still attempt to grow the very marginals as well as those more suited. Janet summed up the British flora well and eloquently. Not only have we retained all of our native species but we have added from the best that the world has to offer~ some being very marginal. I would imagine the US attempts similarly. We even sustain the flora of other climates so they can restock if necessary~ Kew is the keeper of world-wide species ~endangered or otherwise. Their collection is without limit. Visiting Italy I found some fabulous gardens and was somewhat disappointed to find they were of British [usually Scottish] origin. My bluebells cover an acre of woodland and have been with us, as a family, for hundreds of years. The only variation has been an odd white or rose specimen. Our only loss of species has been the Elm and even those are possibly recovering. We had two specimens that showed some resistance. S.O.D has now been identified locally and we will just have to wait and see. Visit the UK if you ever have the opportunity and enjoy our nation wide hobby. Best Wishes. "Cereus-validus" wrote in message . com... Dude, you live in England and you have seem to have no idea what we are talking about. You live in a cloudy rainy climate. You have probably never been to the desert Southwest of the USA nor have ever experienced truly dry conditions first hand and you would surely quickly sunburn and shrivel away under the intense summer head and dryness if you did. Almost everything that presently grows in England is an "exotic" because the natives had completely decimated the forests and wiped out the original native flora ages ago. I have seen so-called wild flower books of England and almost every plant in it was actually an introduced weed from elsewhere in Europe, Asia or even North America. There is now even an aquatic Crassula from New Zealand that has become a widespread pest in England. "Brian" wrote in message ... I feel that it is presence, rather than lack, of imagination that seems to prompt all gardeners to attempt to grow the borderline possibles.Whatever nationality. The flora of a differing climate always seem the most desirable. Personally I have tried and failed with many so-called exotics. Even a little success bring much pleasure~~ Palms and Eucalypts have flourished locally for the last twenty years in SW England and await the first real winter!!. However I have never seen a deliberate mass of Ivy ~~ English or otherwise. I can think of little less desirable. Best Wishes. "Cereus-validus" wrote in message . com... Its symptomatic of the lack of imagination of the average American gardener. There are a huge number of dry land plants, including trees, shrubs, vines, bulbs and succulents, that are vastly more interesting and more colorful than the limited selection of plants that can grow in an English garden. Many Dutch bulbs, especially Tulips, do better under the arid Mediterranean conditions from which they originate than the colder conditions many gardeners force them to grow. The wide variety of succulents from all over the world that can be grown under arid Mediterranean conditions almost boggles the mind. "J. Del Col" wrote in message m... "Cereus-validus" wrote in message . com... Never understood why people insist on trying to create an English garden in the desert southwest when there are thousands of other more suitable and far more interesting Mediterranean climate plants that would do much better under their conditions. You will save yourself and your community much precious water by planting things that will actually thrive in your climate. Indeed. Even Gertrude Jekyll, the panjandrum of English gardening, expressed puzzlement as to why Americans wanted to replicate English gardens in climates unsuited to them. She encouraged them to experiment with native plants and others fit for local conditions. J. Del Col |
