Bighorn Sheep Risk of Contact Tool

April 28, 2021

The Risk of Contact Tool (RoCT) is an R-based implementation of the Risk of Contact model described in O'Brien et al. (2014). It uses a variety of spatial inputs (including telemetry point data, a core herd home range (CHHR) polygon, a habitat raster model, and a set of active domestic sheep allotments) together with estimates of bighorn sheep foray behavior to estimate the probability and rate of contact between bighorn sheep and allotments or other areas occupied by domestic sheep or goats.
The RoCT aims to provide an intuitive browser-based interface to those interested in applying the Risk of Contact model to their own data. The User Guide and its appendices describe in detail the Tool's data requirements, usage, and outputs.
