BLM Pinedale Field Office Implements Anticline Adaptive Management

The Bureau of Land Management (BLM) Pinedale Field Office (PFO) reaffirmed the conclusions of the University of Wyoming Cooperative Fish and Wildlife Research Unit (COOP) and implemented adaptive management (AM) for the Pinedale Anticline Project Area (PAPA) Wildlife Monitoring and Mitigation Matrix (Matrix) on Jan. 11.

The AM changes to the Matrix were made in response to the COOP review and in consideration to of comments from the public and a review team comprised of BLM and Wyoming Game and Fish Department biologists.

Mule deer, pronghorn, and sage-grouse thresholds found in the 2008 PAPA Supplemental Environmental Impact Statement (SEIS) Record of Decision (ROD) Matrix are affected. For mule deer, avoidance distance criteria will be removed from the Matrix since changes in avoidance do not trigger any mitigation action by itself. For pronghorn, habitat fragment size will be removed since changes in habitat availability do not trigger any mitigation action by itself. For sage-grouse, nesting success and habitat selection monitoring will be removed since recent research indicates nesting success does not differ significantly between disturbed and undisturbed areas.

The removal of these monitoring triggers from the Matrix will not affect the BLM’s ability to detect undesirable changes and take appropriate action. Monitoring data, including avoidance distance for mule deer, habitat fragment size for pronghorn and nesting success for sage-grouse, will continue to be collected.

The COOP review and complete administrative record for these AM changes can be found at The original SEIS ROD Matrix can be found at under Appendix B.

The final AM Memos for mule deer, pronghorn, and sage-grouse can be found on the following pages in addition to the Pinedale Anticline Project Office wildlife page link provided above:
