We document three phases in model development which focus on the simulation of bison population dynamics in (1) a brucellosis-free herd, (2) a brucellosis-infected herd, and (3) an infected herd subjected to different vaccination schemes. The model accurately simulated historical changes in herd size, annual recruitment, population age structure, and survivorship of individual cohorts over a 17-year period in a brucellosis-free bison herd on the National Bison Range, U.S.A. (Phase I). The model also accurately simulated historical changes in herd size, and predicted the most likely year of infection, in a bison herd in Grand Teton National Park, U.S.A., that contracted the disease during a 20-year period (Phase II). Finally, the model was used to evaluate a proposed bison brucellosis management plan for the Grand Teton National Park herd which involves annual vaccination of female calves (Phase III).
