Prairie dogs are small burrowing mammals native to North American grasslands. They live in colonies and forage above and below ground for seeds and insects. Ecologists have labeled prairie dogs as a keystone species, a species that is critical to maintaining high levels of species diversity in a community. Imagine a farmer in Kansas kills all the prairie dogs on his farm because he didn’t like “molehills.” Predict the likely outcome in this grassland community when prairie dogs are removed.
