Inventory of amphibians tabular data for Olympic National Park, 1996-1998. These data encompass what was originally three separate databases: ponds, seeps, and streams.

These data contain amphibian records and habitat information from a survey of lentic, seep, and stream habitats in Olympic National Park, 1996-1998. Pond: Four types of survey were conducted for pond amphibians: 1) Opportunisic surveys were simply any search for amphibians that does not qualify as one of the following survey types; 2) Peripheral site inspections required workers to walk all the way around a pond looking for amphibians and searching 1 square meter of substrate for every 10 meters of shoreline. Peripheral site surveys were done for unmapped ponds that were within 100 meters of a pond that was randomly selected to be surveyed from a map; 3) Pond visual surveys were the same as Peripheral site inspections but also involved recordinig habitat variables; 4) Pond visual surveys with trapping were the same as pond visual surveys but aquatic funnel traps were also set out overnight. We deliberately selected clusters of ponds in the park to survey. We randomly chose up to one half of the ponds in each cluster that are shown on National Wetlands Inventory or USGS 7.5 min maps to survey. Seep: Workers walked trails that go up main drainages in the park in September and October. They identified seeps and recorded the position of seeps along the trail. We randomly chose approximately 1/3 to 1/2 of the identified seeps to survey the following year. To survey a seep, two workers searched seep for amphibians by turning over rocks and debris that could be returned to their orginal position. They searched for 15 minutes or until 50% of the seep had been searched. Stream: Workers walked trails that go up main drainages in the park in September and October. They identified streams and recorded the position of streams along the trail. We randomly chose approximately 1/3 to 1/2 of the identified streams in each drainage to survey the following year. To survey a stream, two workers searched 10 randomly choosen 1 meter segments for amphibians by turning over rocks and debris that could be returned to their orginal position. The 10 segments were chosen from a 100 meter stretch that began 30 meter upstream from the trail.
