Explanation of "edge effects"
I read in various places that the geometry and planting layout of a
permaculture garden should exploit "edge effects". The explanation tends to be along the lines that where one planting meets another you get an edge and at edges good things happen so therefore you should do this. What I haven't got yet is the detail of: - what these good things at edges are - very importantly why they happen and - how significant the effects are. I am not trolling for an argument - I really want to understand. Can anybody point me to a resource that explains? David |

Explanation of "edge effects"
Dear David,
Good question, most people dont pay much attention to this place. Graham Bell says: 'All patterns of occupation or behaviour have edges and they offer a particularly rich envronment. This is because the edge of anything is especially rich in species, supporting plants, animals and activities from both its neighbouring areas, and also the species and activities which only take place in that special zone.' One good example is the intertidal zone on the sea shore. This is very rich in species and energy. Think about it and make a list. One not often thought about is that between land and air. How about night and day.? The edge between forrest and cleared areas can be quite a bit warmer due to the edge of the forrest catching the wind which moves the leaves and branches and the friction heats the trees up. So here is and energising factor at an edge. Can we make a list here? All the best wes David Hare-Scott wrote in message u...

Explanation of "edge effects"
The message
from "Graham Burnett" contains these words: Probably two of the most valuable edges of all in Permculture are those which occur when people come together and when ideas come together... Then the London Underground at rush hour must be the world's greatest untapped resource of energy and intelligence, so it's just a matter of time before America claims it's full of terrorists, arranges some pretext to close it, and demands our leader's total obedience and subservience. ....oh dear....

Explanation of "edge effects"
Hi David,
if you type "edge effect" ecology (without the ) in www.google.com you'll get a lot of references and examples. If you have Powerpoint you can download this presentation on Landscape Ecology http://www.ouc.bc.ca/biol/Biol203/Ho...Landscapes.ppt HTH Ute David Hare-Scott wrote: I read in various places that the geometry and planting layout of a permaculture garden should exploit "edge effects".
