Across Jeffco Open Space parks in the foothills and mountains of Jefferson County, a mosaic of ponderosa pine savannas, aspen stands, mixed conifer forests, and other woody vegetation provide shade for park visitors and habitat for dozens of native wildlife species. However, these iconic forests are negatively impacted by stressors such as wildfire, habitat fragmentation, pests such as mountain pine beetle, and long-term changes in precipitation. In response, the Natural Resources team plans and implements a range of forest management projects to improve forest health, reduce wildfire risk, enhance wildlife habitat, and maintain aesthetic and ecological values in our forested parks.
Management actions are initially based on forest inventories and surveys, during which forest conditions are comprehensively assessed and both goals and objectives for the project are defined. Management actions are then refined through consultation with stakeholders, state and federal agencies, and technical specialists. Implementation often involves a combination of Natural Resources staff, private-sector contractors, and researchers assisting with long-term monitoring and evaluation.

Beginning Spring 2021, Jeffco Open Space will be conducting wildfire mitigation and forest restoration in Alderfer/Three Sisters Park. Expect heavy equipment and crews who will be removing trees to a create fuel break, better emergency access, and less catastrophic wildfire conditions.
Short-term impacts will result in long-term, overall health, and increased safety of the area. Estimated project completion is Fall 2021.

Flying J Ranch Park
In 2017, JCOS and Denver Mountain Parks (DMP) jointly received funding from the State Fire Assistance program to implement a forest management and restoration project at Flying J Ranch Park. The project focused on reducing the density of overgrown mixed conifer stands, promoting aspen stands, and restoring ponderosa pine savanna. The risk of catastrophic wildfire was reduced, while both visitor safety and wildlife habitat enhanced.
Flying J Ranch Park Forest Project Fact Sheet
- JCOS received $64,964 for the treatment of 50 acres. DMP received $129,928 for 100 acres. By applying jointly for the grant, together we were able to treat a larger area of the community and also encourage neighbors to treat surrounding private property.
- In summer and fall of 2018, the JCOS Natural Resources team conducted baseline forest inventories to identify treatment areas and to develop specific management objectives. Tree removal began in October 2018 and the project was completed by Winter 2020. DMP completed their tree removal in 2020 and will be removing remaining equipment and material off-site in spring of 2021.
- JCOS treated 62.9 acres total during this project. 21.1 acres were lodgepole patch-cuts, with 43.14 acres of ponderosa pine treatments. DMP treated about 70 acres at Flying J Ranch Park and their remaining acres across the street at their West Jefferson property adjacent to West Jefferson Middle School.
- Over 570 cords of firewood were removed and utilized by the community through two public firewood sales. JCOS also donated ~20 cut-and-split cords to the nearby Conifer Community Church’s Community Firewood Program, which was distributed to lower income and generally elderly residents of Conifer. Additionally, Elk Creek Fire Department helped JCOS deliver over 100 log rounds to Marshdale Elementary School to be used as seats for the schools outdoor, covid-conscious classes.
Regular forest maintenance activities will occur as needed and JCOS will continue to monitor for noxious weed, erosion, off trail use, and other issues.
