SAVING THE OREGON SPOTTED FROGThe first species ever to be emergency-listed as an endangered species in Canada, the Oregon spotted frog has been on the U.S. candidate list for more than 15 years but still has no federal protection in the United States. Named for the black spots that cover its head, back, sides, and legs, the species has an historic range that stretches from California up north past the U.S.-Canadian border. But encroachments on its wetland habitats and the introduction of nonnative plants and animals have almost totally extinguished the frog. Over the past 50 years, the frog has disappeared from 90 percent of its former range — and since it was listed as a candidate in 1991, its habitat has been lost at an accelerating pace. The frog is also threatened by introduced species: Bullfrogs and green frogs compete with Oregon spotted frogs for food, while fish introduced for sport fishing may also compete for prey — or prey on native tadpoles. Invasive plants such as reed canarygrass can make wetland habitats unusable for native frogs. |
