The purpose of this project is to identify and rank the areas with the greatest need of forest thinning around the towns and cities across Colorado according to their proximity to urban areas, forest fire fuel loads, slope angle and aspect. This is intended to assist in the development of forest thinning management plans by indicating which areas pose the highest severe wildfire potential for Colorado’s urban areas. By utilizing the findings of this project, state and local governments will be better equipped to focus resources in areas that will result in the greatest reduction of potential extreme wildfire risk to urban areas with a population greater than 250.
