Geez Furpo, does someone have to explain it to you ?
For the record, I don't think councils manage roadside timber particularly well. That said, they have to deal with idiot humans picking up that wood. Only last weekend came across people picking up wood from a roadside cleanup ( council approved ). They were parked on the wrong side of the road on blind corners in a few different locations of a wet and slippery gravel road because they were too lazy to carry the wood across the road. They had provided no warning around the corner.
They've been known to cut down growing trees, drop trees across fences etc so it is problematic for councils to manage.
The regular country people that rely on firewood every year do it well. It is the fools that rush out as winter breaks that are the problem.
Anyway, back to the worms. Fallen trees provide food for the bugs as they decompose. Those bugs are near the bottom of the food chain so the decomposing tree effectively provides food for much of the environment. Of course those trees also provide shelter for animals and mulch for other plants in the bush.
That's why in a section of natural bush there is plenty of diversity. Go into a blue gum planatation and see how much diversity is there.
Sorry I had to explain that to you.
In your backyard when you were young, how many native animals were living there ?
