Ecological communities within our national parks are often as influenced by the ecological processes and land-use activities occurring outside of park boundaries as they are by management decisions within the parks. Over the past 150 years, ecological processes have been disrupted by increased anthropogenic activity, including replacing migratory bison with non-migratory cattle, conversion of grasslands and other habitats to agriculture or rural development, and large-scale fire suppression. By understanding the landscape dynamics within and around our parks, and the human demographic and socioeconomic factors that drive these dynamics, we hope to be better able to predict disruptive or detrimental changes within our parks and are hopefully better able to plan and implement management to protect our resources.
