Biologist Greg Asner uses spectrometer and laser technology to assess the health of California’s forest from the air. He creates 3D imagery that displays the level of stress within the trees. Our forests are under tremendous stress from having too many trees per acre and not enough resources to go around. The drought is the straw to break the camel’s back. It really demonstrates the need for active forest management to help keep our forests healthy.
