" ... Beginning in the 1990s, British Columbia’s forests were increasingly plagued by a population explosion of mountain pine beetles. This beetle, Dendroctonus ponderosae, destroyed large tracts of forest in the province.

Such widespread forest loss affects more than just the scenery. Forests have economic value, and they provide habitat and food for wildlife. In addition, they play an important role in Earth’s carbon cycle, which affects climate. Healthy, growing forests take up carbon dioxide and produce oxygen. Dead forests produce carbon dioxide when trees decay. Being able to map the location and severity of pine beetle and other insect infestations is a crucial task for forest managers and biologists. ... "
