Hello, I have a pine tree near my house that needs to be cut down, it is becoming uprooted and is likely to fall. I'd like to know if it is beneficial to keep the tree stump for wildlife and if so, what is an optimal height. Tree is currently taller than 2-story house. Trunk is approximately 18" diameter at base. Wondering if 8-10 feet would be beneficial or 2-3 feet for a bird bath. Thank you.
