Wildfire Risk Reduction
Fire is a serious threat along Spokane’s wild border. It has the potential to rip up the hill and destroy homes well beyond the Bluff’s edge. Friends of the Bluff has been working since 2012 to protect homes and parkland from this threat.
In 2019, Friends of the Bluff became a Firewise Community. Firewise enables the group to earn cost-share money from the WA Department of Natural Resources (DNR) for thinning and pruning work we do. We are committed to improving the ecology of the Bluff and protecting homes from fire. Since 2000, over 250 acres have been treated.
If you want to help on your own property, create a defensible space by removing flammable material within a 5-foot buffer from your home. Learn more about being Firewise.
Lop and Scatter
This wildfire fuel reduction technique involves removing the less desirable trees and low-hanging branches in densely forested areas. This prevents fires along the forest floor from climbing into the treetops. After removal, the debris is cut up into small pieces and scattered around the site so it decomposes efficiently.
Watch the video we made with WSU Spokane County Extension to learn more.

Goat Grazing
Over the past several years, Friends of the Bluff has hired a herd of goats from Healing Hooves to lessen fire risk in natural areas by reducing brush and tree sapling density. The goats also help with noxious weeds and invasive brush.
Well-managed livestock is one of the most sustainable ways to address these needs while regenerating healthy soil and storing carbon. Watch our video to learn more.
Fuels Reduction Project
The Spokane Fire Department has won a generous grant to reduce forest fuel and fire risk in the natural lands owned by Spokane Parks, including the High Drive Bluff property.
The Fuels Reduction Project is expected to start on October 1, 2025, and will continue at least through the end of the year. About 200 acres of Fire Fuels Reduction will be completed.
The map shows the areas where the fuel reduction work will be done. Unit 8 is almost complete from last year’s work. Unit 1 will not be included this year due to budgetary restraints, but we will likely do this work in the
future.
The Fire Department requests that recreationists avoid the work areas. There will be large equipment, falling trees, and a variety of hazards while the work is underway. Please leave ribbons hanging on trees so the work doesn’t stray into protected areas.
The work involves removing conifers smaller than 8 inches in diameter. The goal is a 12-to 20-foot spacing between conifers and with branches removed at least 10’ off the ground. Slash will be chipped or masticated and
spread out to decompose naturally.
The forest health will be improved. The spacing of the trees provides more water, sun, and nutrients to the remaining trees, thereby making the stand healthier and more resilient to insects and disease. Fire used to do this thinning naturally, but due to fire suppression tactics, logging over the years, and other factors, this natural process has had to be recreated using mechanical means. Spokane Fire Department and Spokane City Parks will be directly supervising the project. Contractors working on the project will be American Forest Management and Patriot Land Management.

City Crews
At the beginning of 2024, the Spokane Parks Department, Spokane Fire Department Wildland Resource Planner, and the Washington DNR began working together to use a generous grant to reduce fire danger on the bluff by removing overcrowded immature trees and “ladder fuels” that can transform a ground fire into a dangerous forest canopy fire.
Over the next 1-2 years, the plan is to treat the entire bluff. Friends of the Bluff has been working with Spokane Parks and the DNR, from the planning stage to monitoring the project and fielding questions from bluff users and residents.
While it may look startling at first, the appearance of the treated area now closely approaches the historic natural state of a Ponderosa pine forest. If you look closely, you will notice that islands of low-growth shrubs and serviceberry for wildlife, standing dead trees for nesting birds, “nurse logs” for seedlings, Douglas firs, and healthy young Ponderosa pines for succession have been preserved.
While there may be some disruption of trail use and some trail widening as part of the work, no serious erosion or lasting harm has been seen. Watch for native grasses and wildflowers taking advantage of the increased sunlight on the forest floor!
Forest health and fire risk reduction are intertwined. Trees in a forest compete for light, water, and nutrients. Trees that grow in adequate space – and thus have sufficient of the aforementioned resources - are healthier and better able to resist damage from insects, disease, and fire.
High tree density and low-hanging branches increase the risk of intense wildfires that threaten the forest and adjacent neighborhoods. However, when spacing in the forest is increased by thinning (removing some trees), and lower branches are pruned off remaining trees, wildfires seldom climb up into the treetops to become crown fires that leap from tree-to-tree and burn into neighboring communities.
Wildfires that are kept on the ground are easier to control, so they pose less risk to residential areas, to the forest itself, and to firefighters.

Sensitive Timing
In May and June, only tree removal (thinning) is done and the cut trees were taken to the road for chipping. No pruning is done at this time because the pine gall rust fungus is actively shedding spores (the fungal equivalent of seeds) that would possibly infect trees via open, cut surfaces from branch removal.
In July, pruning of lower branches commences close to the road because all cut material must be removed for chipping. This is because pine bark beetles are flying and would be able to find refuge in piles of cut branches.
From August through April, the risk of insects and disease infection is greatly reduced. More intensive treatments can occur during this time.
