The Larimer County Forestry Program is dedicated to serving the citizens of Larimer County and assisting with questions and concerns of vegetation, primarily woody plant material or related issues on their properties and on county lands, including rights of way. Larimer County has a diverse landscape and the issues of the property owners of Larimer County are as diverse. It is our intent to respond to all questions in a timely manner, which may be a site visit, a telephone call, an email or directing one to the person or agency which will provide the best information to the question asked. These services provided are for both urban and traditional forests.
Larimer County has experienced a number of natural but destructive events over the past 10 years which 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 you, the private citizens, and Larimer County we can preserve our wonderful landscape.
