I have two herbaceous plagues to deal with.
Siberian elm and Ailanthus are epidemic where I live. I am working on a property where I cut down a siberian elm two years ago and it still is coming back, despite being cut down on a regular basis and being doused with diesel fuel.
I don't want to use glyphosate and will never, ever use a dioxin based herbicide. Anyone got a good way to kill these things?

larger trees can shade them out, as they are not climax species, but pioneers.

wrong, they easily start in the understory of trees and shoot up past the canopy.
and they dont only grow in areas devoid of natural tree cover. here they displace dozens of species of trees that give us a natural and useful tree canopy.
Why is one tree "natural and useful," and another isn't?
what is a "native" species, anyway?
everything man didnt touch is native.

"A few trees along a fencerow or forest edge can rapidly invade adjacent meadows. In addition to its prolific vegetative reproduction, ailanthus has allelopathic effects on many other tree species and may consequently inhibit succession."
ive seen them do exactly that many many times around here, destroy ecosystems and kill neighboring trees.

Interspersed with them are dead oaks, maples, poplars and pine. They killed everything. Only thing that grows in among them is honeysuckle and it doesn't even climb the trees. We cut down a bunch of them, they are only about 6 inches in diameter but very tall. They made kind of a tropical looking grove. All open with a very high canopy. The ones that my husband cut high (3+ feet above the ground, I have no idea why) did not come back. Everything shorter than that put up suckers like crazy. We cut a bunch of the poles up to try and dry for firewood (worked great by the way, burns wonderfully once it drys), and left a bunch of the poles laying on the ground. A couple of weeks ago, we went back in with machetes to cut down the suckers (so soft, so tender - ha ha ha ha, die little trees) and as I started to whack on some I noticed some leaves all black and shriveled, looking closer, some of the trees were infested with hundreds of little black caterpillars, with webbing running through the branches. A little friend helping us? I have never seen them before and they were on none of the other trees -- we left all infested trees alone. This week we were wandering and checking on things and the poles that were laying on the ground were covered with oyster mushrooms! Pounds and pounds of them. Tried them and they were great. We are going to cut down more and pile them up with the ones making mushrooms now and hopefully we can keep the mushroom culture going. Maybe pour some coffee grounds (we have hundreds of pounds) amongst them to tie they all together. I know oyster mushrooms like coffee -- and apparently tree of heaven as well. I still don't like them but now I don't completely hate them.
