LINCOLN, Neb. (AP) — Nebraska wildlife advocates are trying to repeal a law designed to limit the spread of black-tailed prairie dogs, a critical native species that some ranchers view as pests.

Sen. Ernie Chambers of Omaha presented his repeal measure Tuesday to the Legislature’s Agriculture Committee, saying the current law is too vague and runs afoul of property rights. Wildlife groups and the Nebraska Farmer’s Union support his effort, saying the law is heavy-handed.

The 2012 law gives counties the option to manage prairie dog populations when a landowner’s neighbors complain about the animals on their property. Since the law passed, only Sheridan County has created a management plan.

Larry Dix of the Nebraska Association of County Officials says the county has not fielded any complaints since the law went into effect.
