Larimer County Forestry is dedicated to serving the citizens of Larimer County and assisting with questions and concerns about vegetation, primarily woody plants and trees. It is the intent of the County Forester to respond to all questions in a timely manner, which may be a site visit, telephone call or email, or directing someone to the person or agency that will provide the best information. These services are for both urban and traditional forests.

Larimer County has experienced a number of destructive tree pest events that will affect private property in both the flatlands and mountainous areas of the county for years to come. Continuing and new issues are on the horizon, but with continued efforts by both private citizens and Larimer County, we can preserve our wonderful landscape.


  • Promote forest health education and awareness by way of community presentations and site visits
  • Provide forest and landscape information upon request to county residents
  • Assist other County departments with matters concerning vegetation on County lands, including rights-of-way
  • Enforce the state statutes (C.R.S. 35-4-101 thru 116) of the Pest Control Act dealing with mountain pine beetle, spruce ips, Douglas fir beetle, thousand cankers disease and Dutch elm disease

Don't Move Firewood

Buy it where you burn it.

Moving firewood can spread tree-killing insects and diseases. Buy firewood at or near campgrounds, ideally within 50 miles or less of where you’ll camp. Learn more at www.dontmovefirewood.org and  view the flyer.

  • It is illegal to bring firewood of any non-coniferous (hardwood) species from the quarantined area in Boulder County into Larimer County to prevent the spread of emerald ash borer.
