It is the most common system <br /> in this range. This system occurs primarily on fat to rolling uplands with loamy soils and is <br /> characterized by blue grama. Climate, fire, and grazing influence this system. The short grasses <br /> that dominate this system are extremely drought-and grazing-tolerant. In contrast to other prairie <br /> systems, fire is less important. However, historically, fires that did occur were often very <br /> expansive. Currently, fire suppression and more extensive grazing in the region have likely <br /> decreased the fire frequency even more. <br /> 2.2 Soils Information <br /> In the NRCS soil survey, the area around the site consists of one soil classification.
