Imperiled Amphibians of the West
POSTER: Imperiled Amphibans of the West, May 2003, $3.50 S&H, illustrations by renowned herpetologist Robert Stebbins. This 23" x 36" full-color poster highlights several imperiled frog, toad and salamander species, as well as maps of their current distribution.
Frogs and other amphibians have been making headlines lately due to
their declining numbers in the U.S. and around the globe. What many
people do not realize, however, is that the West is one of the "hot
spots" of decline. As one of the nation's leading river conservation
organizations, Pacific Rivers Council is working to increase
understanding and appreciation of native amphibians and the serious
threats facing them and the watersheds that support them. To help raise
awareness about amphibian declines we have produced this poster,
Imperiled Amphibians of the West, featuring stunning illustrations by
renowned herpetologist Robert Stebbins.
Today, western native
amphibians occupy small fractions of their historic ranges, due
primarily to habitat loss and competition with introduced non-native
species. Despite the widespread interest in amphibian declines, sound
amphibian conservation planning is relatively rare. Few plans have been
developed, even fewer have been implemented, and native amphibian
populations continue to dwindle. As the chart below shows, seven of the
featured species are listed as threatened or endangered under the
federal Endangered Species Act, four are candidates for listing, and
three are protected under state provisions. Scientists are predicting
that two of the species--the relict leopard frog and the mountain
yellow-legged frog--likely will be extinct within decades if management
of them and their habitats is not improved. There are many more
imperiled western amphibians in addition to these that are formally
recognized by federal and state wildlife agencies, and their continued
survival depends on swift protection of healthy populations and
recovery management across their respective ranges.
PRC is
working with scientists, conservationists, and concerned citizens to
reverse native amphibian declines in the West through improved
management of these species and their habitats. We invite you to order
this striking poster, and display it as a symbol of your support for
native amphibian conservation. Contact info@pacrivers.org or
