Whistler is surrounded by forest and as a result is at risk for wildfires. Fuel reduction is one component of Whistler’s Wildfire Protection Strategy.
Fuel thinning in Whistler
The Resort Municipality of Whistler has been conducting fuel thinning projects on Crown and municipal lands since 2004 to reduce the risk of wildfire to our community. The primary goal of fuel thinning is to reduce forest fuel loads within the wildland-urban interface to reduce the ability of fire to spread from the forest into the community and vice versa, and to make wildfires easier to fight. Fuel thinning will be discontinued when the fire hazard goes to high or extreme and will resume when the fire hazard is lower.
Sometimes projects need to burn some of the wood debris. There is no need to report smoke from fuel thinning projects.
The RMOW Wildfire Program 2019-2027 was prepared in summer 2019 to identify priority areas for fuel thinning treatment in the Wildland Urban Interface near neighbourhoods.
Fuel thinning process and goals
Fuel thinning focuses on leaving mature and deciduous trees, while removing ground brush and debris, pruning lower branches, and removing tight second growth trees. This is accomplished by:
- Reducing the number of trees in the stand;
- Focusing on removal of small diameter trees and retaining fire-resistant species such as Douglas-fir and deciduous trees;
- Reduce fine woody surface debris, while retaining larger coarse woody debris for habitat and soil productivity;
- Pruning trees to reduce ladder fuels between the ground and the forest crown; and
- Removing dangerous trees to protect workers, while maintaining high value wildlife trees where possible.
In addition to reducing forest fuel loads, secondary objectives of fuel thinning projects are to protect critical infrastructure and facilities in Whistler, restore open forest conditions and demonstrate the principles and practices of the FireSmart program.
The RMOW completed a study in 2012 to identify where landscape level fuel breaks should be created along forest service roads around Whistler. The focus is on reducing tree densities in tight second growth, rather than removing old growth trees although sometimes that is necessary. Thinning stands within 100 - 200 m of each side of the road reduces the fuel available to feed fire growth and creates safer, defensible areas for firefighting crews to work in.
Wildfire program work completed in the following areas in 2019:
- Kadenwood Road - work was completed on the 24 hectare site in October 2019.
- Cheakamus Lake Road - Phase 1 (C03) - work was completed on approximately 34 hectares.
- Spruce Grove/White Gold - eight of sixteen hectares were completed along the western edge of Lost Lake Park from the Scandinave Spa to the Spruce Grove ball diamonds.
- In addition, the RMOW Wildfire Program 2019-2027 plan identifying the next set of priority areas to treat was completed by B.A. Blackwell & Associates for forests near developed areas
Cheakamus Lake Road fuel treatment
In 2018 The Resort Municipality of Whistler (RMOW) and the Cheakamus Community Forest (CCF) began to thin a total of 113 ha along either side of Cheakamus Lake Road. To allow for efficient and safe working conditions it is necessary to close the road to all public traffic including access by skiers from the south side of Whistler Mountain. Please obey all signs and workers.
In addition the RMOW and CCF are working with WORCA to ensure trails in the area are taken into consideration, and with BC Parks to reduce disruption to the Cheakamus Lake Trail parking lot.
Work is underway at the far end of the road out to the Cheakamus Lake trail parking lot until spring 2020.
- The RMOW and Cheakamus Community Forest are working together on the project.
- 35 ha in the central portion of the road were thinned in winter 2018/19.
- Fuel thinning along the rest of the road resumed December 10, 2019 until spring 2020.
- Find details on the Cheakamus Lake Fuel Treatment Map.
The RMOW is continuing wildfire fuel management in the Wildland Urban Interace (WUI) areas. Fuel thinning work above the Spruce Grove and White Gold neighborhoods along the western boundary of Lost Lake Park resumes April 30. This critical work to reduce impacts of wildfire on the community began in this area in fall 2019. The remaining areas will be treated from April 30 to potentially August 2020. Work will stop once the fire danger rating reaches extreme and resume when the rating goes down.
Spruce Grove and White Gold residents can expect minor noise disruptions during construction hours, 8 a.m. to 5 p.m. seven days per week. Rotating trail closures in two locations of Lost Lake Park are planned between Centennial Trail and the western boundary of the park beginning April 30 until further notice.
The following Lost Lake trails will be closed April 30 until further notice:
- White Gold Traverse (no access from either end)
- Centennial Trail between PassivHaus and Spruce Grove
Beginning May 5, the following trails behind the Lost Lake Passivhaus will be closed until further notice:
- Tin Pants
- Gypsy Drum
- Peaches En Regalia
A detour will be in place at the Lost Lake Park entrance behind Lost Lake PassivHaus from approximately May 11 to 22. The entrance will be closed for an additional day the week of June 8. More information will be shared once a date for this work is confirmed.
Access from the south end of the Lost Lake Trails at the Passive House will be diverted 1.3km on the paved Valley Trail along Blackcomb Way and Lost Lake Road to Cedar Way and Lost Lake Beach. The entrance to Lost Lake beach is closed to vehicle traffic. Parking is available in Day Lot 5.
For safety reasons, trail users are asked to please stay off closed trails, follow signs and instructions of wildfire crew, and leash dogs.
Rainbow Neighbourhood Fuel Thinning Project - ON HOLD
This project within the Cheakamus Community Forest is on hold until the necessary external funding is secured.
The RMOW is partnering with the Cheakamus Community Forest to do the work, and is coordinating with WORCA regarding the trails in the area.
The RMOW received funding for several fuel thinning projects from the Union of BC Municipalities Strategic Wildfire Prevention Initiative to supplement the municipality’s budget to carry out the work. The RMOW is also partnering with the Cheakamus Community Forest on projects within its tenure area and substantial funding is provided by the Forest Enhancement Society of BC.
