Hoary Marmot Abundance in North Cascades National Park 2007-2008 and 2016-2017

December 10, 2020

USGS and NPS biologists used distance sampling to estimate abundance of hoary marmots (Marmota caligata) in North Cascades National Park, Washington, USA during 2007-2008 and 2016-2017. Biologists resurveyed hoary marmots in 2016 and 2017 at 78 point-count stations across 19 sites surveyed by NPS in 2007-2008. Data include marmot detection distances and survey conditions used to estimate abundances at each site in each year. Data also include estimated marmot abundances and covariates used to evaluate effects of weather, snowpack, and vegetative phenology and productivity on marmot abundances. Marmots are classified as adult, subadult, or juvenile for observations in which age was evident.
