This is the closest forum I could think of, since its a page we added to our website, and not quite landscaping or lawn care. Since we have birds, and work with trees, we added a webpage regarding safe and toxic woods for bird perches and toys. The list is a bit longer than wood lists found on bird related sites. We skipped the plant lists, and stuck to the wood issue. Its the page for birds, perches and wood at: www.mdvaden.com If you have friends with pet birds, feel free to forward the location to them.
