Oregon spotted frog released into the wild to halt population crash

In an effort to re-establish their populations in Washington State, approximately 500 Oregon spotted frogs were released into the wild after spending the first seven months of their lives in a captive rearing program.

Endangered Oregon spotted frogs returned to native habitat: here.

The Oregon Spotted Frog (Rana pretiosa) had an historic range from south-western British Columbia to northern California.

The Oregon spotted frog has lost 95% of its habitat. Volunteers count egg masses in March at WA’s Conboy Lake Refuge: here.

    Cricket frog a surprise find

    By Tom Venesky tvenesky@timesleader.com

    The amazing thing about the Northern cricket frog is that Rick Koval and I were able to find one period.

    The cricket frog is listed as a species of special concern and it is expected to be submitted for consideration to be listed on the state’s endangered species list.

    So yes, finding one wasn’t going to be easy.

    Fortunately, Koval found the largest known population in the state seven years ago while doing work for the Pennsylvania Herpetological Atlas.

    Cricket frogs are typically found in the southeast and south-central parts of the state, so Koval’s find in Luzerne County was a surprise.

    “I was walking a wetlands and saw one hop and realized it was a Northern cricket frog,” said Koval, a naturalist with the North Branch Land Trust and Pennsylvania Outdoor Life.

    “I called the director of the atlas program and he was in disbelief that they would be this far north. He came up and verified the find. I had as many as 40 calling males at this site.”

    Because the cricket frog is extremely threatened, the location of Koval’s find, as well as where we found the frog for our herp search, can’t be disclosed.

    Still, just finding one and knowing they are still in the county is a relief.

    According to Koval, their population has declined by as much as 85 percent in the state.

    “Most of the decline is due to loss of wetlands, the use of herbicides and predation from bullfrogs and several species of snakes,” he said.

    The cricket frog we found resembled a spring peeper in size and, like the peeper, is one of three tree frogs in the region (gray treefrog being the other).

    After we filmed and photographed the cricket frog we released it back where it was found, happy to check it off our list and even happier knowing that it still exists.
