Kudzu was the last bioweapons unit of the Union army in the US civil war. It never surrendered, it is still fighting the American South, and winning the guerilla war.
I'm playing whack a mole with my own ivy. Fuck the prior house owners for letting it get out of hand. I got all of it from the trees and the side of the house but it always grows back. I'm still finding sprouts from thick woody vines that have been there forever apparently. I tried removing it from the fence but realized very quickly that it's the only thing holding it together. 😒
And fuck the English for bringing it over (we both know it was them, even their plants are colonizers).
Same. I have a fence that's barely still standing now that I removed the ivy. I've been pulling it and spraying it for several years now. I know I'll never win, but I'm doing my best to keep it in check. The most painful part is when I go to garden centers and see it for sale. It makes me want to cry.
Yeah I quite like the ol’ Himalayan balsam to be honest - very popular with the bumble bees. Gets a bad rap in the uk because it’s supposedly ‘invasive’, but I take rather a dim view of that kind of talk to be sure.
Apart from what others commented on these being two entirely different species, there might be other factors at play as well.
Lianas and vines are pretty common and very diverse, especially in tropical forests. They are usually found as part of the upper canopy and if there is a tree fall, they manage to fill this gap pretty quickly. The trees grow more slowly, but will manage to establish themselves eventually, filling up that gap. But if you cut down an entire forest, trees have a much harder time to establish themselves because the whole ground is just covered in these fast growing lianas or vines. There are studies that look at exactly that, how lianas inhibit forest regrowth.
So, how overgrown with lianas or vines a certain habitat is, is very much dependent on the disturbance of this habitat.
