Eurasian Steppe They indiscriminately consume vegetation in these areas, leaving little room for any one species of plant to out compete another [9]. Monitoring of population health (population size, sex and age structure, diseases, parasitism and mineral values), genetic variation, space use, grazing pressure and rangeland health are framed into an adaptive management program aimed to maintain a disease-free, genetically pure and diverse bison conservation herd.
