USGS science supports management, conservation, and restoration of imperiled, at-risk, and endangered species. Endangered Species Day is commemorated in May, and we’re taking some time to find out just how one goes about studying at-risk species and what part cutting-edge technologies can play in helping us do the science that informs managers and policy makers.

Who's Your Mama? Conservation Genetics and At-Risk Species

Oregon Songbirds: Singing for Their Supper in Evergreen Forests
In this episode we sit down with USGS wildlife biologist Joan Hagar and discuss her recent study on songbirds in the Pacific Northwest. New research indicates a possible relationship between reductions in the abundance of some species of songbird and reductions in the amount of deciduous trees in evergreen forests.

Unearthing the Secrets Beneath the Forest Floor
There is a black box hidden beneath the forests of the Pacific Northwest, guarding the secrets to why the trees grow so large! The black box is soil, which harbors immense biological diversity and controls the release of water and nutrients that support the life above ground.

To Burn or Not to Burn? A Framework to Answer the Question
Prescribed burns are a common tool used by land managers to control invasive plant species and to promote native plants. There are many benefits to using a prescribed burn as a management tool; however, controlling fire is often difficult as it can be unpredictable.

Drab Appearance Masks Complexity of Imperiled Sagebrush Ecosystems
Compared to the rich diversity of forests, sagebrush shrublands contain relatively few species. Yet, these shrublands in the western United States have incredibly complex dynamics that present major challenges for conservation. They are also one of the most imperiled habitats in North America, primarily due to invasive plant species.

Fatal Frog Fungus
The potentially lethal fungal disease chytridiomycosis has been associated with declining amphibian populations around the globe. This rapidly emerging disease, and the chytrid fungus that causes it, have forced scientists to scramble to learn more. There are still plenty of mysteries about the origin and spread of the fungus.

Northwest Mussels Live Long to Tell Their Story
Few would believe the importance of freshwater mussels to scientists here in the Pacific Northwest. These little-known and often-ignored organisms may live for over a century on the bottoms of lakes, rivers, and streams. Freshwater mussels have a story to tell, and researchers have developed a way of ‘reading’ this story.
