Toad migration underway at Jackson Lake

Posted: Updated:

JACKSON, Wyo. (AP) - Biologists say tens of thousands of tiny, just-metamorphosed boreal toads are migrating from Jackson Lake into a nearby picnic area - a sign the amphibian has colonized a new area in Grand Teton National Park.

The Jackson Hole News & Guide reports ( ) the migration has forced park officials to close the Lakeview picnic area to vehicles. Boreal toads top out at 3 to 4 inches, but the ones emerging near the picnic area still have some growing to do.

Debra Patla of the Northern Rockies Conservation Cooperative says she measured them at about a half-inch long.

Conservation groups in the southern Rockies have unsuccessfully petitioned to protect the toad under the Endangered Species Act. Patla says the species is less threatened around Jackson and is "widespread but not common" in the park.
