Forest researchers are swinging from the trees—all in a day of good work.  Researchers at the HJ Andrews Experimental Forest climbed 86 meters (280 ft) into the canopy to ground-truth canopy height data obtained through LiDAR (Light Detection And Ranging).  With LiDAR data, scientists are able to create 3D images of landscape topography and canopy structure at a detail not available previously.  FES Assistant professor Matthew Betts and USFS researcher Tom Spies discussed some of the ways that the LiDAR data are being used—from predicting bird species presence to calculating carbon storage of forests.
