Oregon Zoo releases 22 endangered turtles into the wild

The Oregon Zoo has successfully released 22 endangered northwestern pond turtles into the Columbia River Gorge, marking a significant step in the conservation of this vulnerable species. These turtles were reared at the zoo’s conservation lab after being collected as hatchlings by biologists from the Washington Department of Fish and Wildlife in the spring of 2025. Zoo staff utilized heat lamps and provided abundant food to ensure the turtles grew healthy and robust. According to Jen Osburn Eliot, who oversees the turtle conservation program at the zoo, the head-starting process allows the turtles to develop to a size that increases their chances of survival once released into the wild.

The northwestern pond turtle, also known as the western pond turtle, is classified as an endangered species in Washington and a sensitive species in Oregon. The population of these turtles has faced significant challenges over the years, primarily due to the introduction of the American bullfrog, which is invasive in the region. This species preys on smaller aquatic animals, further endangering the already vulnerable pond turtle population. By growing the turtles to a larger size before their release, the zoo aims to reduce the risk of predation by bullfrogs, giving the turtles a better chance of thriving in their natural habitat.

Prior to their release, the turtles were acclimated to outdoor conditions to prepare them for life in the wild. This process included adjusting their diets to resemble what they would find in their new pond environment. The collaborative efforts of the Oregon Zoo, the Washington Department of Fish and Wildlife, and various other partners have been critical in the recovery of the northwestern pond turtle. Over the past two decades, the population has rebounded from fewer than 100 individuals in Washington to the release of more than 1,600 zoo-head-started turtles back into the wild.

Community involvement has played a vital role in the success of the Northwestern Pond Turtle Recovery Project. Volunteers and local wildlife officials have been instrumental in supporting the release efforts. The project is a partnership that includes the Oregon Zoo, Woodland Park Zoo, U.S. Fish and Wildlife Service, Friends of the Columbia River Gorge, Bonneville Power Administration, and the U.S. Forest Service, among others. Together, these organizations work towards restoring the population of the northwestern pond turtle in its native habitat.

The future outlook for the northwestern pond turtle appears promising, thanks to ongoing conservation efforts and community support. Continued monitoring and research will be essential to ensure the success of these released turtles and the overall health of their population. The dedication of the Oregon Zoo and its partners underscores the importance of collaborative conservation initiatives in preserving endangered species and their ecosystems. Moving forward, the success of the Northwestern Pond Turtle Recovery Project may serve as a model for similar conservation efforts globally, demonstrating the impact of dedicated teamwork in wildlife preservation.
