The dataset contains the recorded locations of amphibians collected in Southeast Alaska from 1867 to 2002. The records were compiled from 15 university and museum collections in the US and Canada. The data contain records for the following species: Northwestern Salamander, Long-toed Salamander, Roughskin Newt, Western Toad, Pacific Chorus Frog, Columbia Spotted Frog, Wood Frog, and the Red-legged Frog.
These data are the result of two years of pond-breeding amphibian visual encounter surveys conducted across a range of pond types (from highly ephemeral to permanent hydrology) in Mount Rainier, North Cascades, and Olympic National Parks. The R code includes well-annotated code for reorganizing and sub-setting the master data, which should make it much easier to work with than the raw spreadsheet. Associated hydrologic data may be of use for other research applications. Recognize that this amphibian dataset is tied to (1) hydrologic projections developed using the Variable Infiltration Capacity model, which provides historical reconstructions of hydroperiod for most of 20th century and future hydrologic projections...
