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.
