Honeysuckle is killing forests and ivy is helping, especially in the northeast/midwest. Kill all that shit, help stop it from spreading. And try to volunteer for local groups that are clearing invasive species. It's pretty amazing seeing a forest before and after invasive species have been removed.
I have a big ass juniper tree out back that has honeysuckle growing all through it. No idea how to get it out.
cut the honeysuckle as close to the ground as you can, apply roundup(maybe with a brush or something to not get it everywhere), and let the stuff at the top die. Roundup kills honeysuckle so well. i used to be against herbicides but now im just against them for cosmetic use(like people using them for grass between sidewalk cracks)
