The ephemeral nature of the constructed ponds will exclude bullfrogs and fish, which are predators and competitors of California red-legged frog. The rain-filled, naturally appearing, low-cost, low-maintenance ponds will benefit California red-legged frog by providing a predator-free pond that will retain water long enough for the entire life cycle of the California red-legged frog. In addition to providing predator-free breeding habitat for a threatened species, the ponds will also provide habitat for birds, bats, and other wildlife.
The BLM ponds are similar to successful ponds built in 2014 on the El Dorado National Forest near a robust California red-legged frog population located on private land. The El Dorado National Forest ponds near Georgetown were occupied by California red-legged frogs within the first year after their construction. California red-legged frog breeding was confirmed in these ponds in 2016. Hopefully, the BLM ponds constructed near Foresthill, California, will be just as successful. Now we wait and see…
The California red-legged frog is our largest western native frog. It’s range has been reduced by more than 70% due to a number of factors including:
-Over harvesting for food during the late 1800s and early 1900s.
-Subsequent introduction of bullfrogs to supply the food harvest as California red-legged frog numbers declined.
-Conversion of riparian and wetland habitats in the Central Valley to agriculture and urbanization.
