Does poison ivy play any useful role in the ecosystem?

Wow, you think the deer would eat it.
Haven’t seen it around here. (The deer munching on it, I mean)

Maybe it just grows faster than they can eat it. I saw it in North Carolina and was disturbed.

It’s nuts. I tell the grandkids not too stand close to it.

Out by the pond there’s one stand of it that has a trunk at least as big around as a 5 gallon bucket. It soars to the top of 4 dying pine trees.
