What happens once a tree dies?
Within 3 to 6 months after a tree dies, its needles will drop to the ground. The snag (a standing dead tree) will stand for a while, usually between 2 and 6 years before falling to the ground. How long a snag remains standing depends on a number of factors, but especially on the rate of decay of the tree’s root system. Dead trees could pose a hazard if the path of their fall threatens structures or areas frequented by people.
