Bullfrogs (Lithobates catesbeianus)
Bullfrogs were accidentally introduced to the western United States through the aquarium trade and trout stockings, and were purposely introduced for pest control and hunting. A lack of native predators of the bullfrog has resulted in significant impacts on the native amphibian, reptile, and fish populations due to bullfrog predation. Bullfrogs eat practically anything that they can catch and swallow, including terrestrial and aquatic invertebrates, fish, other frogs, turtles, snakes, birds, mammals, etc. With limited population control, these amphibians can cause significant harm to an ecosystem before being eaten or moving on to a new habitat.
You’ll find them in the freshwater habitats (streams, marshes, stagnant waters, ditches, canals, lakes etc) in the Santa Monica Mountains.
What you can do!
Stop releasing your pets into the wild! Bullfrogs are hardy animals and just one individual can decimate a large area. Cease intentional stocking of bullfrogs for sport and encourage others to keep native frogs as pets.
Did You Know?
A study that began in 2002 reveals a lion and his offspring are surviving in the Santa Monica Mountains. Radio collars track them crossing roads and navigating through open spaces. Their future is uncertain, but with conservation efforts, they may continue to make these mountains their home.
