Ips Beetles are next. Morris and other scientists are trying to determine the potential impacts, such as more intense wildfires, disrupted watersheds, destroyed habitats, and reduced carbon storage, as climate change spurs increasingly widespread and severe beetle outbreaks. Both … For instance, the whitebark pine, with its especially large and nutritious seeds, is a favorite meal for grizzly bears fattening up before hibernation. Switzerland is preparing for the eventual loss of spruce, its most important tree, as warmer weather fans conditions that will make it nearly impossible for all but those high in the Alps to survive. Mountain pine beetles (Dendroctonus ponderosae; MPB) are native Colorado bark beetles that predominately infest ponderosa pine (Pinus ponderosa), lodgepole pine (P. contorta), and limber pine (P. flexilis).
