A glorious 70 foot tall White Pine has become sick over the winter with
all its needles turning brown. It is located on an island in Georgian
Bay, Ontario, Canada and is well removed from civilization, salt, etc..
No other trees on the island - or the area for that matter - display
this condition.

Is this the work of a pine beetle? If yes, what to do? If not, what has
caused this and is there hope?



At 70' it's a pretty old white pine, probably dying of old age. I have
dozens of huge old white pine on my property, some have fallen and are
rotting away right beside younger specimens. White pine can live 300 years
but that would be exceptional, typically they live 125-150 years. Not every
tree dies of sickness.
