Does anyone know where I could get a handout on forested wetlands that explains the need for brush piles and dead logs for habitat.

Hi Judy,
Below are links to two publications discussing the advantages of adding brush piles or dead snags for wildlife habitat.

Thanks for the information. This is what I was looking for.
