Yes, those damned possums... a never-ending battle here.
My poor fruit trees and silver birches in particular have taken a
hammering this year.

One thing I have found effective is a mixture of lard and kero - I
wiped some around my young silver birches trunks (and any nearby
posts) and 6 months later, no further damage thus far.
But I can't do that to every tree, of course.

Anyway, what I really want to find out is - how high can a possum jump
from ground level? I reckon the only way I can keep my fruit orchard
possum free is to build a corrugated iron fence around the whole
orchard, then a large frame over the lot and cover with bird netting -
this should keep all birds and possums out. The fence will have other
benefits, too, such as keeping the wind out and providing a new pen
for poultry.

The only question is how high to build the fence, anyone have any
ideas on that?

Thanks.
