    Importance of Prairie Dogs to the Grassland Ecosystem
    Prairie dogs are called a "keystone" species in grassland ecosystems. In other words, the prosperity of prairie dogs is essential for the well being of other animals. One thing provided by prairie dogs is homes when the prairie dogs leave their burrows. For example, as the population of prairie dogs has decreased, the population of the burrowing owls that live in abandoned prairie dog holes has diminished. These small critters also make soil more nutritious when they dig and they move about 500 pounds of soil for every burrow they create. Then, the nutrition is passed into plants and grazing animals such as deer, elk, cows, and pronghorn. Another way prairie dogs help the grassland ecosystem is controlling the height of plants around them, which gives them an advantage when spotting predators while it allows other plants to flourish and increases plant diversity. Last, prairie dogs are an abundant food source for animals of all kinds. Digging homes, improving the quality of the soil, managing the plant growth around colonies, and providing a constant food source are the main, very important roles of prairie dogs in the grassland ecosystem.

    Threats to Ecosystem:
    Poison used to exterminate the prairie dogs also poisons the plants around the prairie dogs (South Dakota Department of Agriculture produced 150,000 pounds of poisoned oats in 1991 alone)
    Habitat destruction has shrunk the grasslands that prairie dogs live in. Colonies now are often too small and widespread to support large populations.

    Conservation Plan:
    1) Ban the shooting and poisoning of prairie dogs and have an organization, such as the Colorado Division of Wildlife, accept the role of estimating and controlling the growth of prairie dog populations
