Integrative Whitebark Pine Ecosystem Restoration Initiative

Whitebark Pine is an endangered keystone species of high-elevation ecosystems. It is an important food source of many species of wildlife, most notably the Grizzly Bear and Clark’s Nutcracker. It is endangered due to the introduced White Pine Blister Rust, Mountain Pine Beetle, fire, and climate change. The most effective means for Whitebark Pine recovery is through promoting the regeneration of blister rust-resistant seedlings via planting or natural means, retaining healthy trees on the landscape, and ensuring the perpetuation of natural recruitment. This project will directly aid in recovery by planting seedlings grown from potentially rust-resistant parent trees and by determining how local Clark’s Nutcrackers are utilizing Whitebark Pine forests and aiding in its recovery.

Update: 2,000 Seedlings Planted

In September 2017, 2000 seedlings were planted on Mount MacLean in the Bridge-Seton River Watershed, near Lillooet. The Whitebark Pine seeds, rich in fat and protein, are increasingly recognized as an important source of food for bears and other creatures. This tree species is at risk due to a blister rust fungus imported to North America, mountain pine beetle kill, and warming temperatures that allow other species to encroach on its high elevation territory. These are very slow growing trees. Volunteer planters hope to ‘give nature a helping hand’ and assist this important species to continue to survive. The planting was done by the Lillooet Naturalists, Splitrock Environmental employees and T’it’q’it members, including Chief Shelly Leech.


Final Report: Executive Summary

Whitebark pine (Pinus albicaulis) is a blue-listed species in British Columbia and listed as endangered under the Species at Risk Act (SARA) primarily due to white pine blister rust, mountain pine beetle, fire suppression, and global climate change. This project aligns with the Bridge-Seton Species Action Plan (2017); including the following:

  • Action 37: Inventory and restoration for at-risk (e.g., SARA-listed, red- and blue-listed) and/or culturally important plant species and ecological communities; and
  • Action 38: Build upon previously-funded Whitebark Pine work.

In early summer we surveyed two locations for late summer restoration implementation. This included a survey of the Mount McLean fire for planting suitability and a survey of the Blustry Mountain area for competition removal locations and planting of a rust screening field trial.

A total of 2,100 whitebark pine seedlings were planted on Mount McLean over a total area of 5.18 ha in early September 2017. Seedlings were planted using a combination of paid and volunteer planters from the community. The number of seedlings planted was lower than planned 7,000 seedlings over 18 ha due to funding shortfalls and limitation in accessing other sites due to fire hazards.
