America’s diverse ecosystems are an asset to current and future generations by supporting economically and recreationally important fish, wildlife, and lands. Healthy ecosystems support people and nature, fostering prosperity and enjoyment for all.

Bulldozer lines create breaks in vegetation and are commonly used when fighting wildfires.  This dozer line was created during the Palisades Fire in Los Angeles County, California in January 2025.

The northern rubber boa is an example of a species predicted to have a smaller climate-niche space by the end of the century. Under climate scenario RCP 8.5--which assumes carbon emissions stay near current levels--this species' range could be reduced from most of the northwestern U.S. to only a small portion of British Columbia.

Goose Lake, on the Oregon-California border, is one of the 20 terminal lakes identified by USGS partners as priority ecosystems for study by the Saline Lakes Ecosystems IWAA.

Shown here is a colony of the threatened Elkhorn coral, Acropora palmata, that has succumbed to "bleaching," that is, lost all its algal symbionts (also called zooxanthellae) because of the summer 2023 ocean-heat wave. The coral is attached to a cement block as part of the U.S.

Shown here are three SCUBA divers installing shade structures over experimental Elkhorn corals (Acropora palmata) that have become "bleached," that is, lost all their algal symbionts (also called zooxanthellae) because of the summer 2023 ocean-heat wave. The corals are attached to cement blocks as part of the U.S.

A dim light shines during the summer Arctic morning in the Chukchi Sea as groups of Pacific walruses' rest.  USGS and USFWS conducted joint research expeditions in 2023, 2024, and 2025 to collect data on the Pacific walrus population.  Skin biopsy samples are collected from walruses hauled out on sea ice to help scientists estimate population abundance and

The Saline Lake Ecosystems IWAA Waterbird Movement Project began tagging American Avocets in March 2023 to track their movements across the landscape. Tracking data from these birds will help scientists better understand why these birds choose to use the terminal lake and wetland habitats they do in the Great Basin.

Lake Abert, Oregon is one of the 20 terminal lakes identified by USGS partners as priority ecosystems for study by the Saline Lakes Ecosystems IWAA.

American Avocet are a bird that relies heavily on the Saline Lakes ecosystem during their spring migration periods. Over 50% of these birds exist here. Part of their use includes using the terminal lakes there to breed.

Eared grebes in a courtship behavior in the Great Salt Lake. They are one of many migratory birds in the Great Basin that rely on terminal lakes and wetlands in the area to stop rest and feed.
