Trees Across America has a tree planting program with which About's Forestry Guide would like you to get involved. So what, exactly, can you do to help? Well, you can plant trees, for one thing -- which you may even be able to get for free! "Currently, the best place to check for free trees is to get in touch with your state forestry group," advises Steve Nix. "They often provide free trees to local and community organizations, and they may also have advice for helping you with your project."
