elven tree, where?

i just cant seem to find the so called elven tree in WE, its used in many campaigns and cinematics, its a tree wich is very high and can have the color orange and yellow... Where can i find it, do i have to DL and import a model of it? o_O

Look in the download section on models

Yup you have to, I made a map with the green tree model for you.
Unfortunately I don't know how to use the Orange Model.
