OTHELLO, Wash.– Hundreds of endangered northern leopard frogs leapt back into the wild at the Columbia National Wildlife Refuge in Grant County last week. The releases were made possible by a partnership of the Washington Department of Fish and Wildlife (WDFW), U.S. Fish and Wildlife Service (USFWS), Oregon Zoo, Washington State University (WSU), and Northwest Trek Wildlife Park. WDFW collected northern leopard frog eggs earlier this spring, and after months of growing at the Oregon Zoo and Northwest Trek Wildlife Park, the frogs were ready for release. Once abundant throughout North America, northern leopard frogs are rapidly disappearing from their …

The scene was hushed with concentration. Eleven scientists and Northwest Trek staff members bent over rows of tables outside the Northwest Trek conservation center, far outside the public area at the Eatonville wildlife park. Birds chirped in the surrounding forest. But the real stars of the intense scientific focus were some 350 northern leopard frogs – most of whom were sleeping soundly under anesthetic. It was tagging and measuring day, an effort involving three different partner organizations, in careful preparation for releasing these endangered frogs back into the wild of eastern Washington. The goal? To help repopulate a vanishing species. …

Focusing intently, Jessica stares into the swirling depths of a big black water tank. Summer sun reflects off the surface, air bubbles stir up the mid-layer and the bottom is in deep shadow. On first glance it’s nearly impossible to see that the tank contains over 100 plump, wriggling tadpoles. But Jessica – an animal keeper at Northwest Trek Wildlife Park – suddenly dives her bare arm into the water with a small net scoop. “There you are!” she says, pleased, and gently deposits one tadpole into a shallow net pen floating at the surface. It’s vet check-up time for …

Amphibians are excellent ecosystem monitors. If their populations are changing, you can bet something is happening in the habitat. That’s why Northwest Trek staff routinely survey the grounds for eight different species: rough skinned newts, northwestern salamanders, long-toed salamanders, Western toads, Oregon spotted frogs, red legged frogs, Pacific tree frogs and bull frogs. That data is regularly reported to the Washington Department of Fish and Wildlife to better protect and conserve the amphibians for the future. Northwest Trek’s recent temporary closure to help slow the spread of coronavirus has not stopped staff on grounds from monitoring for egg masses of …

On a clear spring day at Northwest Trek, Amy Newton is standing hip-deep in a chilly pond. Waterproof notebook and GPS in hand, she peers into the cloudy water. “Guys! We need your help over here – I think it’s a Pacific tree frog!” she calls. With the moon-walk gait of people who don’t want to squish anything, John Miller and Kim Bryant wade over and inspect. “Yeah, I think so,” pronounces Miller. “So cool,” adds Bryant, gently fingering the sloppy, Jello-like mass in the water. It’s Amphibian Egg Mass training day at Northwest Trek, and Miller, Newton and Bryant …
