Bighorn sheep distribution and winter ranges were reviewed and updated during 2002. The layer does not necessarily include overall distribution or winter range within Tribal lands/Indian Reservations or National Park Service lands. Overall distribution polygons represent general or year round habitat. Winter range polygons represent areas occupied by the species from November 15 to March 1. The polygon attribute to select overall distribution and/or winter range areas for big horn sheep is BHS_USE.
Abstract (from http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0148795): Arid climates have unpredictable precipitation patterns, and wildlife managers often provide supplemental water to help desert ungulates endure the hottest, driest periods. When surface water is unavailable, the only source of water for ungulates comes from the forage they consume, and they must make resourceful foraging decisions to meet their requirements. We compared two desert bighorn sheep ( Ovis canadensis nelsoni) populations in Arizona, USA: a treatment population with supplemental water removed during treatment, and a control population. We examined whether sheep altered their seasonal diets without supplemental water....

The allotment (Range Management Unit) feature class depicts the boundaries of range allotments and wild horse territory on the Dixie National Forest. Each unit is a designated area of land available for livestock grazing.
Bighorn Sheep modeled corridors in Colorado by the Southern Rockies Ecosystem Project (now Center for Native Ecosystems) encompassing the most important expert and model identified corridors from the Linking Colorado's Landscapes project that cross highways. The modeled corridors represent the corridors that were modeled using the Corridor Design tool http://corridordesign.org
