Thinking about how to do wooded terrain for Dirtside, I got a big cheap bag of model trees from Amazon. The Hexon tiles include 'forest' tiles, so I glued some tree bases to them, a stuck the trees in the bases.

This gives me removable trees for travel and placement of models during a game. With 5 trees to a hex for heavy woods, and 3 for light woods, I think it gives a reasonable look, plus hopefully keeps playability.

Tank hiding on hex for scale.
