About

Central Oregon Hay Growers Association

COHGA is here for the community, and we want you to be a part of it! Central Oregon is a special place to live and our life in agriculture connects us all. Formerly part of Oregon Hay and Forage, COHGA now is a 501c3 focused on carrying on the work of the Central Oregon chapter. Please join COHGA. Your membership keeps our community going. Please lend a hand to the many activities going on. Volunteer for the education events or sit in on a board meeting. Email us your photos for use on our website or post them to Facebook. We all need to spread the word about the quality hay available in Central Oregon. And don't forget to get our youth involved!
