As autumn continues and leaves fall, it’s essential to be aware of a potential hazard known as “zombie trees.”

These trees may appear alive but are, in fact, dead or dying internally. This condition can lead to weakened branches or even the collapse of the entire tree, posing severe risks of injury or damage to property.

Zombie trees often succumb to pests or diseases that deteriorate their health from the inside out. Indicators of a zombie tree include dying branches, unusual leaf discoloration, or premature leaf drop. Additionally, increased activity from woodpeckers may suggest internal decay, which can be further confirmed by fungi growing on the tree.

While dead or dying trees can create essential habitats for birds and mammals in forest ecosystems, they can be dangerous in urban areas. If you suspect a tree may be a zombie tree, it’s advisable to consult a professional arborist for a thorough inspection. Arborists can recommend appropriate treatments to restore the tree’s health, such as pruning dead branches or applying fertilizers.

For more detailed information on tree care, consider referring to the US Forest Service’s Trees Owner’s Manual. If you suspect a tree is compromised, don’t hesitate to seek professional help for safety and maintenance.
