NORTHERN RED-LEGGED FROG
Selina Heppell, Danielle Nelson, Tiffany Garcia
Latin name: Rana aurora
The Northern Red-legged Frog is a native pond-breeding amphibian that is recognized by Oregon as a Sensitive Species. This species has been impacted by introductions of invasive American Bullfrogs and habitat loss in western Washington and Oregon. This cryptic species is often missed because they call exclusively underwater, a behavior that has been studied by Danielle Nelson. Research on the emergence, movement, and dispersal behavior of this species has been carried out by both Nathan Chelgren and Evan Bredeweg. This is complemented by work from Jenn Rowe, who examined landscape factors that influence Northern Red-legged Frog populations. These research efforts inform wildlife management of conservation of this species.
