that dead trees do not increase the occurrence or intensity of wild fires? Or that Bark beetles are a native species and not an invading force?
In fact, not only do dead trees and Bark beetles not increase fire risk, they are both essential to a healthy forest ecosystem.
Native Bark beetles always exist in our forest, but at certain points in time, such as during a period of drought, these insects increase their numbers in order to weed out the less fit trees, creating snags (dead trees), and enabling the fittest trees with the best DNA to have the resources they need to survive. This creates a healthier, more resilient (able to survive the tough times) forest.
Not only do Bark beetles improve forest health, they also increase native biodiversity. They themselves are a food source for many birds and even other insects, and the dead trees they create provide homes for cavity nesting birds and mammals and permit flowering and berry producing shrubs to germinate in the sunlight attracting even more species!
