Resilience

allow some change in current conditions, but encourage eventual return to original conditions

Management Goals

  • Build resilience to drought, fire, white pine blister rust, windthrow, bark beetles
  • Promote future-adapted native tree species and genotypes (drought) to create multiple ways for vegetation development
  • Promote lodgepole pine for serotiny (fire resilience)
  • Promote rust-resistant
  • Pinus flexilis (limber pine) genetics
  • Retain genotypes on site (refugia-like)
  • Create a heterogeneous structure and reduce fuels in the matrix
  • Promote wildlife habitat by retaining large diameter trees and snags
  • Provide ecosystem services, including wood products, watershed health, recreation opportunities, and cultural resources
  • Create opportunities for carbon sequestration by retaining larger trees

Strategies & approaches

  • Group selection to encourage lodgepole regeneration

  • Remove 20-30% of the basal area creating 3 2-acre groups and 3 1/2-acre groups

  • Place groups near overstory lodgepole pine to facilitate natural regeneration

  • Generally thin the matrix to promote healthier stands

  • Overall reduce the stand density by 10-20%

  • Remove Engelmann spruce <10” dbh, while maintaining mature/live spruce

  • Remove subalpine fir across all size classes >5” dbh
    Keep lodgepole pine and any Populus tremuloides (quaking aspen) present

  • Passively allow any natural regeneration to establish within matrix

  • Favor aspen and lodgepole pine in open areas
    Plant Douglas-fir (local source) and rust-resistant limber pine

    The seedlots that will be used for Douglas-fir and limber pine reforestation in the resilience treatment will come from nearby populations, as shown on the maps. They both come from areas with average 1970’s climates that are drier and slightly warmer than the planting site, as indicated in the plots. The “period” corresponds to the climate projections for the average number of frost-free days and mean annual precipitation at the planting site in the 30 years centered on the 1970’s, 2020’s, 2050’s, and 2080’s. Numbers next to the seedlots on the map show the elevation in feet that the seedlot is from.

  • Maintain snags to help promote wildlife

  • Minimum of 4 snags/acre, retained in larger clumps if possible

  • Wildlife supported: boreal owls, lynx snowshoe hares, boreal toad, elk, deer

  • Reduce ladder fuel build-up while leaving some to promote roughness, soil moisture, and nutrient cycling

  • Lop and scatter (20-35 tons/acre) to encourage lodgepole pine height growth and seedling survival during drought years.

  • Allow for regeneration of spruce
