National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Abstract	Olympic National Park (ONP) comprises 370,000 ha of land on the Olympic Peninsula in Washington State. The park includes the Olympic Mountains as well as a 100-km strip of Pacific coast. ONP has 13 species of amphibians: 3 stream/seep breeders, 7 pond breeders, and 3 terrestrial breeders. Three resident amphibians represent families endemic to the Pacific Northwest. ONP has the richest herpetofauna of the three National Parks in Washington State. We developed new inventory techniques for amphibians in streams, seeps, and ponds in ONP in 1995. These techniques are suitable and effective for conducting broad inventories when many surveys must be conducted over large areas. The techniques can also be adapted to long-term monitoring and we have developed an example of this approach for streams. We conducted extensive surveys of streams (167), seeps (250), and ponds (167) in ONP from 1996 to 1998. These surveys determined the distribution and, for streams, abundance of amphibians over most of ONP. We found that most species were common and widespread within the environmental limits that they were previously thought to occur. One exception was the western toad which was rare at high elevations despite its known ability to thrive at high elevations in other regions. The other exception was Cope's giant salamander which was not detected in the northeastern portion of the park including the Elwha River drainage. Reed Glesne and Ronald Holmes simultaneously conducted similar surveys in North Cascades National Park.
