Over 20 private property owners in the Glenwood Valley and the U.S. Fish and Wildlife Service have signed an agreement for management of lands to preserve habitat for the Oregon Spotted Frog and maintain agricultural activities.  The frog is listed as a threatened species, and the Glenwood Valley is home to a population of the species.  Klickitat County Commissioners helped facilitate the agreement.  Commissioner David Sauter feels the agreement with benefit all parties, with property owners making some adjustments to their practices including when haying takes place and when water goes on and is withdrawn from fields and when it is kept in canals.  Sauter says it is a 20-year agreement.
