Wildlife biologist Kathleen Smith checks a turtle nest cage, or exclosure, for hatchlings near Fern Ridge Reservoir on July 26, 2022. As a federal agency, the Portland District provides certain protections to wildlife at Corps’ reservoirs. During nesting season, Portland District wildlife biologists search for signs of the threatened native species of turtle, the northwestern pond turtle. When biologists find a turtle nest, they’ll remove the “nest plug” the mother turtle created, and gently poke the eggs. If the eggs are firm, like a chicken egg, biologists know the nest belongs to the northwestern pond turtle. If the eggs are softer and dimple under pressure, the nest belongs to an invasive species of turtle, the red-eared slider. After determining the type of turtle egg, biologists will place the exclosure around the nest to protect it from racoons, skunks, and other animals. Northwestern pond turtle exclosures allow the hatchlings to leave the nest once hatched, while red-eared slider exclosures keep the hatchlings at the nest site until biologists can remove them.
