Cannon Fire Project

Mill Creek looking west after burn

Background

The Cannon Incident fire burned approximately 22,750 acres total between June 16 and June 28, 2002. The fire was ignited by a campfire. Of the total acreage, approximately 4,556 acres burned at high intensity and 8,848 acres burned at moderate intensity. The fire was strongly influenced by high winds (20-30 miles per hour), dry fuel conditions, a variety of fuel types and mountainous topography. Vegetative resources were impacted due to the burn pattern and variations in burn intensity.

Mule deer habitat was severly impacted by the fireKey Issues

  • Threat to terrestrial ecosystem integrity due to increased risks of weed invasion
  • Soil erosion risks and associated increased sediment loads into endangered Lahontan Cutthroathabitat
  • Loss of critical mule deer winter range

 

 

 

Fire Emergency Stabilization and Rehabilitation Goals

  • To prescribe cost effective post-fire stabilization measures necessary to protect human life, property, and critical cultural and natural resources
  • To promptly stabilize and prevent further degradation to affected resources on lands within the fire perimeter or downstream impact areas and mitigate damages caused by fire suppression operations in accordance with approved land management plans and policies, and all relevant federal, state, and local laws and regulations

 

 

Rehabilitation Goals

  • To repair or improve lands unlikely to recover naturally from severe wildland fire damage by emulating historic or pre-fire ecosystem structure, function, diversity, and dynamics according to approved land management plans
  • Restore or establish healthy, stable ecosystems, even if these ecosystems cannot fully emulate historic or pre-fire conditions as specified in approved land management plans

Prescribed TreatmentsPhoto of Drill Seeding Equipment

  • Drill seed 833 acres (actual - 200 acres due to USFS area calculation error) with native shrub, grass and forb species between the second and end of the third growing season following wildfire control (Table 3)
  • Conduct monitoring on drill seeding treatment sites between the second and end of the third growing season following wildfire control
  • Conduct weed detection/control studies on 600 acres to determine if noxious or invasive species are present or increasing in the recovering burned area or in the drill seeded sites
  • Install 2 straw bale check dams in Mill Creek and 120 (30/gully) straw wattles in North Creek
