The U.S. Fish and Wildlife Service has completed a five-year status review of the Columbian white-tailed deer and found that it has met the criteria outlined in its recovery plan. As a result, the Service is recommending the deer be removed from the federal Endangered Species List.
This recommendation is not a final decision, and the subspecies remains federally listed for now. Any change in status would require a formal rulemaking process, including public comment and further scientific review.
This development marks a major milestone in the decades-long effort to save the Columbian white-tailed deer, a conservation journey defined by “collaboration, science, and persistence,” says the USFWS.
Columbian white-tailed deer were once plentiful in Oregon and Washington. By the 1940s, their numbers were reduced to fewer than 1,000 individuals due to habitat loss and human development. In response, the deer were among the first species listed under the Endangered Species Act.
While one population in Douglas County, Oregon, met its recovery goals and was removed from the list in 2003, the Columbia River population remained listed as endangered until it was reclassified as threatened in 2016.
Thanks to years of collaboration among federal, state, tribal, and local partners, the Columbia River population of deer have made a strong comeback. The National Wildlife Refuge System has been especially critical to this success. Established in 1971 to protect this subspecies, the Julia Butler Hansen Refuge for the Columbian White-Tailed Deer has long served as a stronghold. In recent years, translocated deer have also established a thriving population at Ridgefield National Wildlife Refuge, helping create a stable foundation for the deer’s recovery.
In addition to refuge lands, the deer inhabit private lands, with several subpopulations located between the Julia Butler Hansen and Ridgefield National Wildlife Refuges. With funding from Bonneville Power Administration and support from state wildlife agencies, some deer were relocated to a Columbia Land Trust property, creating a vital steppingstone between Cottonwood Island and Ridgefield National Wildlife Refuge. This network of safe habitats has helped the deer populations expand, migrate, and stabilize.
The success of the Columbian white-tailed deer recovery is a testament to long-standing partnerships. The Deer Working Group, which includes the Cowlitz Indian Tribe, Washington Department of Fish and Wildlife, Oregon Department of Fish and Wildlife, Columbia Land Trust, and others, continues to support the implementation of deer conservation efforts.
Even with the recommendation for delisting at the federal level, the deer remain listed as threatened in Washington State. The Washington Department of Fish and Wildlife continues to oversee the listing and recovery of species in Washington.
National Wildlife Refuges such as the Julia Butler Hansen Refuge for the Columbian White-Tailed Deer will continue managing for the subspecies well into the future, supporting habitat, monitoring population health, and fostering resilience in the face of environmental changes and other challenges.
“It’s incredibly exciting to see the deer reach this milestone,” said Bridget Fahey, acting Regional Director of the Pacific Region of the U.S. Fish and Wildlife Service. “We want to acknowledge the significant role that our national wildlife refuges, state and tribal partners, and land trusts have played in this recovery. This effort shows what’s possible when we work together to recover a species.”
