Healthy trees provide many benefits to communities by cooling streets and providing shade, habitat for wildlife, and safety and well-being for families. Unhealthy trees, on the other hand, pose risks and should be inspected. Signs of an unhealthy tree include the presence of mushrooms, dead or dying limbs, cracks in the bark, weak branch unions, and decay. Anyone noticing these signs in a tree should immediately consult an arborist to assess the tree's condition and address any health issues or risks.
