Projects and Research

We use science and innovative technology to manage and conserve terrestrial and aquatic resources. Collaboratively with partners, we seek to effectively meet today's complex conservation challenges. Learn about some of our projects below.

The U.S. Fish and Wildlife Service’s report “Feasibility Assessment:  Sea Otter Reintroduction to the Pacific Coast” is now available! 

The U.S. Fish and Wildlife Service was directed by Congress to look at the feasibility and cost of reintroducing sea otters on the Pacific Coast, including Oregon, Washington, and California. This directive stemmed from language that was...

The Oregon Department of State Lands is developing a Habitat Conservation Plan (HCP) for the Elliott State Forest in Oregon’s Coos and Douglas Counties. The plan will balance forest research and management activities with the conservation of rare species and their habitat on the Elliott State Forest. The Service prepared a draft Environmental Impact Statement to analyze the potential...

The northern spotted owl is one of the most studied birds in the world. Monitoring spotted owl populations throughout the species’ range in Washington, Oregon, and California is an extensive effort conducted among several agencies and partners. These efforts are not designed to count the number of individual spotted owls but rather to gather sampling data from which population trends are...

Latest News: On July, 22, 2022, the Service published our intent to prepare a draft Environmental Impact Statement (EIS) for a barred owl management strategy. This announcement opened a 30-day public scoping period that closes August 22, 2022. For more information and project updates, see below.

The U.S. Fish and Wildlife Service identified competition from non-native and...

The goal of this experiment was to test the feasibility of barred owl removal to determine whether it improves conditions for spotted owls. We removed barred owls from less than one twentieth of one percent of the range of the barred owl.

USFWS Wraps up Experimental Removal of Barred Owls for the Conservation of Northern Spotted Owls.

Bull trout were once abundant and widely distributed in Oregon's Willamette Basin, including the Clackamas River. They were an important component of the river’s native fish assemblage that evolved over thousands of years. Unfortunately, this native char was extirpated from the Clackamas River Subbasin and had not been seen in the Clackamas River since 1963. Bull trout were listed as...

Bull trout were listed as threatened under the ESA in 1998 due to declining populations. The USFWS recommends monitoring populations in subbasins where little is known about the populations, including the Grande Ronde and Imnaha Subbasins. Redd counts have been conducted for over 20 years in the Wallowa Mountains of NE Oregon and is important for determining relative abundance and distribution...

The Oregon spotted frog is the most aquatic native frog in the Pacific Northwest and its habitats include lakes, ponds, wetlands and riverine sloughs. This species has been documented in British Columbia, Washington, Oregon, and California. Unfortunately, this frog has lost 78 percent of its former range and has been extirpated (locally extinct but exists elsewhere) from California....

There are 740,000 acres in California and Jackson County, Oregon, which are designated as critical habitat for 15 wetland animals and plants listed as threatened or endangered under the Federal Endangered Species Act, by the U.S. Fish and Wildlife Service.  The four animal species include:  Conservancy fairy shrimp, longhorn fairy shrimp, vernal pool tadpole shrimp, and vernal pool...

Using Beaver for Climate Change and Conservation Benefits

Beavers play an incredibly important role in our world, altering and shaping the landscape. As nature's "engineers," they build dams that provide deep water that protects them from predators, gives them access to plentiful food, and provides underwater entrances to their dens. Their tree-felling and dam-building activities create...
