Ash Tree Removal and Replacement

Ash Tree Removal

The City of Longmont is taking a conservative approach to ash tree treatments and has and will continue to preemptively remove ash trees that meet one or more of the following conditions:

  • Located under utility lines
  • Poor health and/or condition
  • Small diameter

Trees under utility lines require additional maintenance and tend to have a compromised form. Smaller diameter trees will be removed and replaced. EAB treatments with Tree-Age causes minor wounding at the injection sites that could compromise the health of the tree.


Tree Planting

The City of Longmont plants trees on an annual basis and strives to replace much of the canopy lost from removed ash trees. A resilient urban forest that can withstand future invasive insects and climate change requires a diverse mix of species. Currently, ash comprise approximately 13% of the City of Longmont’s public urban forest. Longmont seeks to have no more than 10% of each genus represented in the urban forest.

Wood Utilization

Forestry Services has strong connections with the local woodworking community and partners with companies to re purpose logs to keep this valuable resource out of the landfill.
