For a few years now I have been slowly building up a collection of wood based sound effects. I have recorded almost everything I could from gigantic trees falling and rotten stump rips to small branches breaking.
Earlier this year I found a busted up tree fort some kids must have built many years ago in the woods behind my house. A nearby dead tree had fallen right through the structure and split it in half and left all the wood laying on the ground. The wood had been there for many years and was very wet from all the forest debris building up. I salvaged as much lumber as I could and moved it to my open field so it could dry out under the summer sun.
