The USDA Forest Service uses many forms of technology to manage 193 million acres that comprise the National Forest System: handheld data-entry devices and satellites; modeling software and LiDAR (light detection and ranging) remote sensing; and desktop computers and servers.
Streams and rivers are a rich repository of minute traces of genetic material from all organisms that live in or near the water, from the tiniest microbes to fish, mammals, and trees. This environmental DNA (eDNA) can tell a detailed story about the life within and around the waterbody.
