Radar on Drones

Small, Unmanned Aircraft Systems (sUAS) or drones can be used to monitor extreme flows in basins that (1) respond quickly to precipitation events, (2) are not gaged, (3) are located in terrain that restricts access and equipment deployments, and (4) are altered by events such as wildfires. 

The research will explore the use of sUAS platforms to measure water depth, water levels,...

Surveillance for the Presence of White-Nose Syndrome in the Bat Community at El Malpais National Monument, New Mexico

In 1999 and 2000, FORT conducted a survey of bats at El Malpais National Monument and adjacent lands. During this study, several species of bats were documented, including some that are known to use caves or lava-tube formations as roosts. In the winter of 2006–2007, the fungus-caused disease known as “white-nose syndrome” (WNS) began devastating populations of hibernating bat species that use...
