Bison population size and migration movement are influenced by both density dependent factors and density independent ones. To determine which percentage each one contributes in the bison ecology is a key challenge for YNP. Indeed, bison respond to pressure (human and natural) by migrating in lower elevation outside the park where forage availability is higher. But bison in Yellowstone National Park are infected by Brucella abortus, a disease that typically causes birth abortion in ungulates. When bison exit the park, they are likely to transmit the disease to livestock grazing near the park boundaries. It is as much a scientific as an economical and social issue that creates conflicts between public and private lands owners. To address the bison management dilemma of increasing bison tolerance outside the park and to avoid brucellosis transmission, YNP try to find the best management policy possible. One of the tools that might help decision maker is the Forage Production Tool, a GIS application created by the NASA in the order to help YNP in wildlife monitoring.
