Napalm. I was actually thinking the same thing when riding home through the Banyowla/Roleystone map - not about it being a great map but it needed napalming to get rid of all the parrotbush that's overgrowing many of the tracks.
Doesn't napalm just remove leaves not logs?
I think we need to do extensive studies either way. If there's not enough results from Banyowla we can move to Pinjarra Hills for more science.
