- YOSEMITE NATIONAL PARK -- The bullfrogs that used to greet tourists at the
- Ahwahnee Hotel are no more.
- The amphibians the size of a fist or larger were rounded up and destroyed
- because they were damaging Yosemite Valley's ecosystem, park spokesman
- Scott Gediman said yesterday.
-
- "We are trying to eradicate them because of their voracious predatory
- behavior," he said. "They eat insects, fish, other amphibians, and even
- some small birds and mammals."
-
- National Park Service scientists said the non-native bullfrogs also helped
- destroy native foothill yellow-legged frogs and California red-legged
- frogs.
-
- The yellow-legged and red-legged frogs have become virtually extinct in the
- Sierra, but park officials are planning to reintroduce them to Yosemite.
-
- Scientists don't know how the bullfrogs from the eastern and Midwestern
- regions of the United States came into Yosemite Valley. Wildlife biologists
- believe someone dumped the first of them in a pool outside Ahwahnee Hotel.
-
- "Maybe someone 50 years ago came in and introduced them into Yosemite,"
- Gediman said. "They were simply tolerated for the last 50, 60 years. But we
- felt it was time to intervene."
-
- So the park's wildlife biologists drained the pond three weeks ago and
- rounded up the critters in the middle of the night. Armed with flashlights,
- biologists caught 45 bullfrogs and 200 pounds of tadpoles.
-
- The bullfrogs were killed with blows to the head, which Gediman said is the
- most humane way to destroy them.
-
- The biologists went back to the pond Tuesday to see if any bullfrogs were
- left, but didn't find any. Gediman said park officials will continue
- looking for the bullfrogs in other ponds or wetland areas in Yosemite
- Valley.
-
- "We're monitoring other areas and trying to eradicate them from
- everywhere," Gediman said.
