In the forest, beetles can influence resource management in many ways, some positive and some negative. Bark beetles are a natural part of our southwestern forests. They have evolved with ponderosa pine for millenia. In a sense, they function as nature's thinning agents, removing the sick, old or weakened trees. Effects of beetles on wildlife species depend on the species involved.
Dead trees provide habitat for many species which utilize snags for nesting, roosting or foraging.
Clumps of dead trees create openings which create habitat for others. Extensive mortality may create habitat for some but may also reduce it for others. Presence of dead trees, especially in large numbers, can also increase fire hazard. Evidence of attack varies some by species and is discussed later in these notes. In general, if a tree has red boring dust in the bark and small round entrance holes, or pitch tubes, it may be infested.
