Small Unoccupied Aircraft System (sUAS) Flights Active
Small Unmanned Aircraft Systems (sUAS) are an emerging technology which may result in safer and improved methods to conduct wildlife surveys. The objective of this task is to test the capabilities of various cameras and sensors onboard a small Unoccupied (or unmanned) Aircraft System (sUAS) to determine if they are a useful and effective tool to inventory various flora and fauna important to USGS partners and collaborators.
In the first application of a sUAS to a natural resource management need, the USGS and U.S. Fish and Wildlife Service (FWS) are compared the video imagery collected on the Raven A sUAS with simultaneously collected data from ground-based counts to estimate the population of Sandhill cranes migrating through Colorado’s San Luis Valley. Cranes are large, upright birds (up to 4 ft tall) that migrate through the refuge in early spring. The birds can be counted while aggregated in this important “staging area” on their migratory route. This initial work determined (1) to what extent vehicle noise affects the birds at various altitudes above ground; (2) whether the birds can be seen well enough to count from different altitudes; (3) how views compare between the two camera types (color and thermal infrared) used on the sUAS; and (4) how closely the sUAS aerial counts align with those conducted by observers on the ground.
A second study conducted by USGS and Colorado Parks and Wildlife tested the ability of a thermal sensor mounted on the Raven sUAS to detect a much smaller bird, the Greater sage-grouse, on their lek. Over the course of these and additional studies, scientists will identify which types of field applications will benefit most from using a sUAS, what species can be detected with the cameras and sensors, and the efficacy of this method for aerial surveying in different environments.

Ecological Flows
Ecological flow is a central theme of AS Branch studies, as our research examines how water flows affect populations, communities, ecosystems, and hydroscapes. Our studies elucidate the interactions among hydrologic, geomorphologic, biogeochemical, biological, and anthropogenic processes. Branch scientists identify and quantify the spatial and temporal attributes of water flow for ecological needs... - Publications

Unmanned aircraft systems in wildlife research: Current and future applications of a transformative technology
Unmanned aircraft systems (UAS) – also called unmanned aerial vehicles (UAVs) or drones – are an emerging tool that may provide a safer, more cost-effective, and quieter alternative to traditional research methods. We review examples where UAS have been used to document wildlife abundance, behavior, and habitat, and illustrate the strengths and weaknesses of this technology with two case studies.AuthorsKatherine S. Christie, Sophie L. Gilbert, Casey L. Brown, Michael Hatfield, Leanne HansonDevelopment of a decision support tool for water and resource management using biotic, abiotic, and hydrological assessments of Topock Marsh, Arizona
Topock Marsh is a large wetland adjacent to the Colorado River and the main feature of Havasu National Wildlife Refuge (Havasu NWR) in southern Arizona. In 2010, the U.S. Fish and Wildlife Service (FWS) and Bureau of Reclamation began a project to improve water management capabilities at Topock Marsh and protect habitats and species. Initial construction required a drawdown, which caused below-aveAuthorsChristopher Holmquist-Johnson, Leanne Hanson, Joan Daniels, Colin Talbert, Jeanette HaegeleEvaluation of the Raven sUAS to detect and monitor greater sage-grouse leks within the Middle Park population
Staff from the U.S. Geological Survey Fort Collins Science Center and the Colorado Parks and Wildlife Hot Sulphur Springs Office began discussions in 2011 for a proof of concept study to test the Raven RQ-11A small Unmanned Aircraft System (Raven sUAS) for its suitability to detect and monitor greater sage-grouse (Centrocercus urophasianus) breeding sites (leks).
