Cooperative Fish and Wildlife Research Units 2020 Year in Review

The Cooperative Fish and Wildlife Research Units program (CRU program) is a unique cooperative partnership among State fish and wildlife agencies, universities, the Wildlife Management Institute, the U.S. Geological Survey (USGS), and the U.S. Fish and Wildlife Service. This geonarrative highlights the activities and accomplishments of the program and its cooperators for calendar year 2020.

Chronic Wasting Disease Map

Reported distribution of chronic wasting disease (CWD) in North America. 

Inland Fisheries Across the World: Assessing the State of Freshwater Aquatic Resources

Inland fisheries represent 12% of total global fishery production, provide accessible and affordable high-quality protein to some of the world's most vulnerable populations, and lack the traditional assessment processes necessary for estimating harvest potential. This project aimed to develop a scalable framework to assess the current and future status of inland fisheries worldwide. 

Flow Photo Explorer

The Flow Photo Explorer is an integrated database and machine learning platform for estimating streamflow from timelapse imagery. The goal of this project is to develop new approaches to monitoring hydrologic conditions in streams and rivers where flow data are historically sparse or non-existent.

Chronic Wasting Disease Research by the U.S. Geological Survey & Partners

The USGS, the science bureau of the Department of the Interior, conducts wildlife disease surveillance and research to support management of affected species and their habitats. Here you will find information on USGS science addressing Chronic Wasting Disease across the Nation.

Building a Cloud Forest From the Ground Up

California's Channel Islands were once home to cloud forests, but this unique ecosystem was lost. USGS & partners are bringing them back.

Central Valley Water and Land Use Futures

To support coordinated conservation in California, wetland restoration, and climate adaptation planning, we developed projections of the Central Valley's seasonally flooded cropland and wetland habitat for five scenarios that vary by water availability and management priorities.

Habitat Vulnerability Assessment for Wintering American Black Ducks

We estimated food availability among five main wetland cover types used by overwintering American Black Ducks: subtidal, fresh water, high marsh, low marsh, and mudflat. Bioenergetics models used to inform North American Waterfowl Management Plan (NAWMP) can be simplified into two major components: energetic demand and energetic supply. 

Endocrine Disrupting Compounds in the Chesapeake

Findings from US Geological Survey studies on sources, occurrence, effects and risk of contaminants throughout the Chesapeake Bay Watershed.

Ecological Drought Across the Country

Learn about how the Climate Adaptation Science Centers have been exploring the topic of ecological drought across the country. 

Exploring the Fish and Climate Change Database (FiCli)

An interactive geonarrative exploring the Fish and Climate Change (FiCli) Database.

2020 Climate Adaptation Science Centers Annual Summary

A geonarrative highlighting the Climate Adaptation Science Center's science, partnerships, and capacity building activities from Fiscal Year 2020.
