Trees
I knew when planning out the layout I would need hundreds of trees. Both Aspens for the south and south east sides and conifers of several types for the remainder of the layout. Purchasing commercial trees are $3-5 each to $20-40 each which was far beyond any resources I have. So, I looked at several commercial trees for ideas as well as dozens of You Tube video's on how others built their forest. My friend Ron Keiser from the Denver area has a very nice basement layout which will be featured in an upcoming Gazette issue. He has purchased trees as well as made trees with caspia branches and a few other dried weed branches. He's also used fine detail fern branches from Hobby Lobby.
