It makes sense that a living tree in your backyard can be beneficial for wildlife as a source of habitat and food. But what if that living tree falls over and dies? While it may look like an eyesore, a dead tree can actually be more beneficial for wild animals than a living one. Many animals prefer to nest and create shelter in dead trees because wood-eating insects that are feasting on it are tasty treats to them. If a tree appears to be dead, try to leave it alone. Upright dead trees are ideal, but even ones that have fallen to the ground can be beneficial to all sorts of wild animals.
