Research in Support of Native Amphibians

American Bullfrog—Invasive in the Western U.S. and a threat to native amphibians
NOROCK, along with our collaborators, have recently published research about helping the National Park Service update their amphibian species database and evaluating biological and chemical threats to amphibians. See below for more information.
Background
Amphibians are experiencing global decline and land use change, water management, pollution, climate change, pathogens, and invasive species are some of the factors driving that decline. Resource managers need information about the threats to native amphibians so they can make informed decisions about how to manage both the native and the invasive amphibian species that threaten them.
In addition to understanding the threats to native amphibians, it is helpful for managers to know what species are on their lands. The National Park Service is a major federal land manager in the West and recently worked with the USGS to update its amphibian species dataset so they can be more confident of what species are on their lands.
