Field Notes
I was on a trail, on Mackworth Island, and I was looking for Asian Bittersweet. It was thundering so there were a lot of clouds. I was by a cliff and below it was a rocky shore with seaweed. Behind us was a large forested area. The Asian Bittersweet was covering most of the trees we saw, the plants on the ground was fine but the trees it was on were dead.

Oh no. You can really see what you mean in that last photo. It must be weighing the trees down.
