You are referring to these trees, yes?
I am the creator of them, so I'll just send them directly.
My friend made a request to essentially recreate 'LotR: War of the Ring' on Wc3, so I went about playing WotR on one screen and modeling on the other, so far these trees, a bush, and an uruk are what I've got.
Here is a screenshot of the game.

I've been having a bad time compressing my textures, so they are of much lower quality in wc3, until I can find another way at least.
The Spruce tree isn't animated, I'll be working on that soon.
Here are the trees in their current state.
