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.
This pair of images show patterns of forest clearing and regrowth in Wasghington state over 26 years. Such images help scientists understand how human decisions impact the carbon cycle and Earth’s climate.
A small plane flying low over remote forests is sending back eye-popping aerial photography—as well as scientific measurements that will improve understanding of how Alaska’s forests are responding to global warming.
In recent decades, industrial logging has intensified in the dense tropical forests of central Africa, but few data sets exist that can help ecologists and policymakers monitor the occurrence and impact of logging over wide areas in that part of the world.
