Tallgrass prairie is disappearing because farming and development have replaced it. This ecosystem is home to a unique group of plants, animals, and microbial life. The processes of fire, grazing by animals, and drought are important to the tallgrass

Loss of grassland species resulting from activities such as off-road vehicle use increases the need for models that predict effects of anthropogenic disturbance. The relationship of disturbance by military training to plant species richness and compo
