You may see City of Aspen employees or city contractors out in our trails, parks, and open spaces spraying noxious weeds. They are helping to ensure the plants in our native habitats don’t become outcompeted by imported invasive species! We take all precautions and follow all manufacturer recommendations for the safe and effective use of herbicides. Please keep children and pets clear of areas being treated. If you need more information, please contact City Forester David Coon at [email protected] or PH: 90-920-5120. – City of Aspen Parks and Open Space Dept.
