What's New

Conservation Strategy Update

Sage Grouse, Wyoming

  • The Association submitted the final draft of the conservation Strategy (integrated CCAA/CCA/CA) to the US Fish & Wildlife Service (FWS) on July 23, 2013.
  • An Interagency Memorandum of Understanding (MOU) was finalized May 16, 2014 by the Association, FWS, BLM, Forest Service, and Wyoming Game & Fish Department.  This MOU defines the responsibilities of each party and establishes a Conservation Advisory Committee to advise the Association Board.
  • The Strategy is currently undergoing final review by FWS.  This review should be completed by mid-June, 2014.
  • The Association has hired a third party contractor to complete the necessary Environmental Assessment (EA) for the Strategy under the direction of FWS.  FWS, along with BLM and Forest Service as cooperating agencies, are expected to finish review of the draft EA by June 30, 2014.
  • Members are working with the Association to assess threats and develop appropriate conservation measures.

The Next Steps

  • Following signing of the Interagency MOU, the Association is in the process of inviting qualified professionals to serve on the Conservation Advisory Committee.
  • Once final reviews of the Environmental Assessment are complete, it will be made available for public comment.
  • We anticipate signing of the Strategy in the third quarter of 2014.
