The Woodland Park Zoo and the Washington Department of Fish and Wildlife released over a hundred endangered western pond turtles to their native habitat in an effort to restore the population.

Western pond turtles once commonly inhabited the western coast of the United States. But several threats, including predation by the non-native bullfrog, disease, and habitat loss, put them on the bring of extinction since the early 90s.

In 1991, the Western Pond Turtle Recovery Project was established. Each year, recovery workers monitor adult female western pond turtles during the nesting season. They protect nesting sites with wire cages to prevent predators from eating the eggs. Then in the fall, the eggs and hatchlings are transported to the Woodland Park and Oregon Zoos where they can grow in safety.

“We return the turtles to their homes every summer once they reach a suitable size of about 2 ounces, a safeguard against the large mouths of bullfrogs,” explained Dr. Jennifer Pramuk, Woodland Park Zoo’s reptile curator.
