capitalizing on the unique skillset and talents provided by modelers and data analysts who have experience modeling with extreme large datasets, such as accelerometer data, as well as conduct research to assure that bison in the Great Sand Dunes (GRSA) ecosystem are not causing damage to park resources.This funding opportunity is to conduct research on resource selection and ecology of free-ranging bison across the western USA. Specific research will conduct modeling of data collected over 2 years in 3 wild bison populations, that span the Rocky Mountain region and Great Plains ecosystems.The goal of this research is to increase understanding of bison ecology, and to relate this information to public land managers to protect natural resource assets that belong to the American people, to improve management of bison on the landscape, and to improve management of habitat. Scientific analysis will be performed by a tight collaboration of USGS and University scientists.
