They are food for coyotes and similar predators, no? They have a place in the ecology of the area.

They also destroy farmland and dig holes that cause hoofed animals to break their legs. The population got way out of control when their predators were mostly driven off by humans. And again, they spread bubonic plague. They are about as ecologically important as mosquitos. I understand the Venn diagram of HN users and people who grew up rural is infinitesimally small, but they are well known nuisance animals.

Come on, coyotes are classified as a least endangered animal and for good reason; they breed like crazy and eat almost anything. They are also a massive nuisance to livestock, a minor danger to people and they'll eat your cat or dog given half a chance. Culling prairie dogs would just mean their population would be slightly less booming.
