Welcome to Butte Sink Wildlife Management Area!   

Butte Sink WMA primarily consists of properties that are privately-owned and under conservation easement conservation easement
A conservation easement is a voluntary legal agreement between a landowner and a government agency or qualified conservation organization that restricts the type and amount of development that may take place on a property in the future. Conservation easements aim to protect habitat for birds, fish and other wildlife by limiting residential, industrial or commercial development. Contracts may prohibit alteration of the natural topography, conversion of native grassland to cropland, drainage of wetland and establishment of game farms. Easement land remains in private ownership.
