To conserve the genetic foundation tree species need to survive and adapt in the face of insect and disease infestation and climate change, forest management decisions must consider how genetic diversity is distributed across species’ ranges. ; Hulcr, J.; Koch, F.

Michael Wojtech’s book Bark, A Field Guide to Trees of the Northeast is a huge help. Contact: Thomas Holmes, Climate Change Influences on Mountain Pine Beetle and Spruce Beetle Phenology and Associated Impacts in Western North American Forests Other factors such as competition may play a role, but temperature can be particularly limiting. The economic and social costs of outbreaks, however, can be significant. In some species the bark looks similar throughout the life of the plant, while in others there are dramatic changes with age. Effect of increasing temperatures on the distribution of spruce beetle in Englemann spruce forests of the Interior West, USA. They benefit the environment by providing homes for various forms of life, cooling our climate and improving our soil. The smoothness of their bark helps check the tendency of other rainforest plants to grow on them. Bark is the outer covering of a tree’s trunk and branches.
