A shallow-rooted invasive plant attracts bees and provides nectar, but its weak roots let it be pulled up easily and it chokes out native plants. When it dies, bare mud washes away in rain, causing erosion and slope failure.
Why is it so bad? Well, depends who you talk to. Like, bees love it. It's probably the bees' favourite thing. So it's really good for the bees. But see on this hill, so it's on like quite a steep slope, and look how shallow-rooted it is. Like, you pull it, you pull them up and they just come straight up. What happens is it outcompetes everything, as you can see, and then it dies and just leaves behind mud, and then the rain comes and it'll all just fall down.
