  • Whitebark pine (Pinus albicaulis) is a keystone species of high elevation ecosystems in the Greater Yellowstone area (GYA), and is currently at significant risk from the combined effects of insects, the introduced disease white pine blister rust, climate change and successional replacement throughout its range, and is under review by USFWS for potential listing under the Endangered Species Act, with a decision document due in 2019.

  • In the face of an acute threat to a critical long-lived species, the GYCC Whitebark Pine Subcommitee is actively implementing the Whitebark Pine Strategy for the Greater Yellowstone Area (2011) with its associated Adaptive Action Plan – Whitebark Pine in the Greater Yellowstone Area (2015). Ongoing actions include extensive protection and restoration efforts, such as cone collection and planting across the GYA, and the establishment of a GYGT seed orchard and clone bank on the Custer-Gallatin NF.

  • The GYCC Whitebark Pine Subcommittee includes a minimum of one representative from each GYCC agency and collaborates extensively with the research community and partners such as the Whitebark Pine Ecosytem Foundation and other non-government/non-profit organizations.  The Forest Service, Park Service, BLM, and Fish and Wildlife Service renewed their commitment for another five years in an MOU signed by regional officials in March 2017.
