Overview • Introduce Environmental Assessment on hazardous fuel reduction treatments within the Red Rock Canyon National Conservation Area • Proposed Alternatives • Potential Affected Resources • Next Steps
Purpose and Need The purpose of the Proposed Action is to reduce the threat of unwanted wildland fire in Red Rock Canyon NCA due to invasive annual grasses by chemical herbicide, mechanical mowing or mechanical blading treatments.
What is the problem? A Hazardous Fuel, Fire Prone Invasive Annual Grasses
The Invasive Annual Grass Fire Cycle • Invasions shorten fire return interval • Less time for native vegetation to re-establish • Invasive grass species thrive on disturbance • Non-fire adapted species disappear off the landscape due to repeat burning • Breaking the fire cycle will allow for recovery of the ecosystem.
A Need for Action • Provide for visitor and firefighter safety • Protect Red Rock Canyon infrastructure • Protect and enhance natural vegetation and habitat • Reduce annual grass expansion
Our Number One Priority is Visitor and Fire Firefighter Safety • Red Rock Visitors • 1 Million Annually (approximately) • 13-Mile Scenic Drive • One-way Road • Traffic Congestion • Evacuation Concern • Emergency Access Concern • The Fires are Fast Moving, Difficult to Control and Threaten Visitor and Fire Fighter Safety.
Protect and Enhance Natural Vegetation and Habitat • Protect Mojave Creosote-Bursage Desert Scrub which is poorly fire adapted. • Protect Blackbrush communities which are poorly fire adapted. • Reduce Annual Grass Expansion and Prevent Unwanted Repeat Fires.
Fire Behavior • Lightning and human ignitions • Annual grass is a fine flashy continuous hazardous fuel • Current Situation: Intense, fast moving fires that are hard to stop • 150 Ft – 300 ft. Fuel breaks slow or stop fires • Treatments in fire scars will reduce re-burn • Treatments provide for visitor and fire fighter safety
What fuel break alternatives are being considered ? • Herbicide (Preferred) • Mechanical Mowing • Mechanical Blading • No Action
Preferred Alternative: Herbicide • 2,114 acres linear fuel breaks along approximately 65 miles • 2,346 acres of burn scar treatment • Max. Width up to 300 ft. • Targets invasive annual grass • Reduces fire behavior in treated areas • Maintains shrub communities • Reduces fire potential • Short-term impacts to non-target species • Temporary Closures
Mechanical Mowing • 2,114 acres of linear fuel break along approximately 65 miles. Excludes fire scars. • Max width 300 ft. • Creates areas of reduced fire behavior • May cause mortality in brush communities • May promote invasive species • Temporary Closures
Mechanical Blading • 2,114 acres of linear fuel break along approximately 65 miles. Excludes fire scars. • No-burn areas • Max width 300 ft • Fire scars not treated. • Increased soil disturbance • Increased weeds • Temporary Closures • Loss of vegetation
No Action • No fuel breaks are created • Danger to public and environment remains. • Multi-day closures during wildfires. • Fire prone invasive species expand. • Fire intolerant, natural species and habitat are lost at the landscape level.

Public Comment Requests • Are there additional issues that need to be considered? • Is there additional information, data, analysis, which should be considered? • Are there factors that may impact treatments that weren’t considered?
