Summary

USGS scientists counted American pikas (Ochotona princeps) and hoary marmots (Marmota caligata) in North Cascades National Park, Washington, USA during 2016. Hoary marmots were resurveyed in 2017, primarily by the National Park Service. Surveys occurred at sites of previous studies by Jason Bruggeman (pikas - 2009-2013), Aidan Beers (pikas - 2013-2015), and Roger Christophersen (marmots - 2007-2008) and followed protocols implemented by these researchers. Data include animal counts, survey locations, and survey dates for all surveys conducted by USGS. Marmots are classified as adult, yearling, or juvenile for observations in which age was evident.

Purpose

Pika and marmot counts were collected to assess effects of weather and snowpack dynamics on these species. Counts are measures of relative abundance that may be used to evaluate species habitat relationships and population dynamics. These data are compatible with pika and marmot surveys that occurred in previous years at the same sites.
