Insect Damage in British Columbia Forests

As the size of British Columbia’s pine beetle infestation has grown, forest managers have begun to need a technique to identify damage over large areas. Relying on a variety of data sources, including satellite data, scientists from Goddard Space Flight Center conducted a survey of insect-damaged forests in British Columbia. This image shows their assessment of insect damage overlain on a topography map.

Forest Changes in British Columbia

In British Columbia’s Coast Mountains, some 200 kilometers (125 miles) inland from the Pacific Ocean, rivers and lakes cut tortuous paths through rugged terrain. The peaks and valleys in this region are covered with forest, but the forest has changed over the years due to human use and insect pests, in particular, the mountain pine beetle.
