They live in backyards, parks, fields, creeks or just about anywhere, but in many areas their numbers are dwindling. Frogs and toads face major threats, and up to one-third of the world’s amphibian species are in danger of extinction.
Frogs and toads play an important role as both prey and predator in wetland ecosystems, and are considered indicators of the health of their environments. But many previously abundant frog and toad populations have declined dramatically in the United States and around the world.
The Santa Barbara Zoo is part of FrogWatch USA, a national “citizen science” effort to identify and count frogs and toads.
The information gathered is entered into an online database from all FrogWatch chapters over the past 15 years – and may ultimately lead to practical and workable ways to stop amphibian decline.
FrogWatch Training at the Zoo
FrogWatch Training is Now Online!
Can you hear frogs or toads from your backyard? Become a certified volunteer for FrogWatch USA to directly contribute to their conservation! After four webinar training sessions, you’ll be able to identify the calls of nine local frogs and toads and participate in a national citizen science monitoring program.
At home with no toads around? This is still a great way to learn about native amphibians with your family!
”It is essential that we understand the scope, scale, and cause of declines in frog and toad populations. FrogWatch volunteers have helped by gathering data for more than 10 years.— Estelle Sandhaus, PhD, Santa Barbara Zoo's Director of Conservation & Science
