Colorado State Forest - Resistance

Treatment: maintain RELATIVELY UNCHANGED CONDITIONS OVER TIME

Desired Future Conditions

The goal of this treatment is to maintain the current conditions such as species composition and general stand structure as possible, while reducing the site’s tree density. This includes retaining the species composition (except for mature Abies lasiocarpa (subalpine fir)), surface fuels and snags, and disturbance regimes for high-elevation spruce-fir forests.

Management Goals

  • Build resistance to windthrow, beetles, and drought by limiting tree mortality
    • Reducing stand density can reduce the physical stress on tress which can then help build resistance to windthrow, drought, and beetles
  • Promote tree vigor and release, increase wind firmness, and remove dead trees
  • Provide ecosystem services, including wood products, watershed health, recreation opportunities, carbon sequestration potential, and cultural resources
  • Provide lynx habitat (need some large trees)
  • Maintain aesthetics / recreation value

Strategies & approaches

  • Mechanical thinning to remove dead trees, trees with mistletoe, and some green trees
  • Release cut to reduce stand density and encourage advance regeneration
  • Alter species proportions through favoring healthy spruce and lodgepole
  • Create surface fuels for soil moisture retention and surface roughness (20-35 tons/acre)
  • Maintenance of snags for wildlife use by keeping at least four per acre with a DBH greater than or equal 10 inches for Picea engelmannii (Engelmann spruce) and subalpine fir, and a DBH greater than 8 inches for Pinus contorta (lodgepole pine)

Site Leads & Partners

Blair Rynearson, Zach Wehr, Carolina Manriquez, and John Twitchell from the Colorado State Forest Service are the site managers helping lead the Colorado State Forest ASCC Project. Mike Battaglia (Rocky Mountain Research Station) and Ethan Bucholz (Colorado State Forest Service) are scientists helping lead the research efforts for the site.
