Lakes Basin fuels reduction implementation

Whitebark Institute, under the authority of the Inyo National Forest (INF), is collaborating on forest restoration by thinning trees to a more natural density to reduce the risk of high-severity wildfire within Mammoth Lakes and to overcome the current bark beetle infestation present in the area. Guided by foresters, the project follows the parameters of the National Environmental Policy Act (NEPA) implemented by the INF for fuels reduction of Mammoth Lakes Basin. Trees are selected using a marking guide which determines the number of trees per acre (including healthy ones) that will need to be removed to reduce excess fuels that have built up over 50 years. The area, dominated by lodgepole pine, is very dense and overcrowded with an increased sign of bark beetle activity.



Tree removal work is extremely dangerous. 


Please stay out of the project area for your safety and the safety of the crews. Stay tuned and follow Mammoth Lakes Trail System for updates on road closures and detours:

Project Dates

Work begins mid-September, after the high season for recreation visitation.

Anticipated Scope of Work

Treatment area will be covered by thinning trees < 20“ diameter at breast height (DBH) and hazard trees < 30” DBH. The trees have been pre-marked focusing on removal of dead and diseased trees first and low value trees next. There will also be removal of all dead trees up to 30” DBH and a selection of dead trees over 30” DBH. All cut trees will be moved to the decking location (see map) to reduce fuels and improve forest health.

Multi-Use Path Closures

Multi-use pathways and Lake Mary Road will be intermittently closed while work is underway.
