Riparian
Riparian
Riparian ecologists in the AS Branch study interactions among flow, channel change, and vegetation along rivers across the western United States and worldwide. Our work focuses on issues relevant to the management of water and public lands, including dam operation, climate change, invasive species, and ecological restoration. Investigations take place on a range of scales. For example, experimental studies in pots and growth chambers detect genetic, phenotypic, and species variations in response to environmental conditions, such as drought, frost, mycorrhizal inoculation, salinity, and carbon dioxide enrichment.

Ecological Flows
This research examines how water flows affect populations, communities, ecosystems, and hydroscapes. Studies elucidate the interactions among hydrologic, geomorphologic, biogeochemical, biological, and anthropogenic processes. Scientists identify and quantify the spatial and temporal attributes of water flow for ecological needs. Flow alternations by humans are a primary contributor to the...
Small Unoccupied Aircraft System (sUAS) Flights
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...
