Prescribed Fire

Prescribed fire being applied at Sonoma Valley Regional Park

Fuels reduction project Shiloh Ranch Regional Park: Work crews will be conducting a French Broom removal and fuels reduction project at Shiloh Ranch Regional Park along the Mark West Creek Trail starting January 2, 2024 and lasting several weeks. An Air Curtain Burner will be used as part of the project. All trails will remain open during work, however, park visitors may experience disrupted activity or notice smoke when using impacted areas.

Pile burning at Cloverdale River Park: Work crews will be conducting pile burns at Cloverdale River Park on Monday, April 16, 2024. All trails will remain open during work, however, park visitors may experience disrupted activity or notice live fire and/or smoke when using impacted areas.

Pile burning at Carrington Coast Ranch Regional Park and Open Space Preserve: Work crews will be conducting pile burns at Carrington Coast Ranch on April 17-18, 2024. The park is currently not open for public access, so there are no direct impacts to visitors. However, people in the area may notice live fire and/or smoke.

California’s Fire-Adapted Landscapes

Many of California’s landscapes are fire-adapted, which means trees and vegetation that have experienced frequent fires have developed traits that make them resilient to or dependent on fire. Here in Sonoma County, oak woodlands, redwoods and grasslands evolved with fires set by Indigenous Peoples as a way of maintaining healthy and vibrant ecosystems. As a result, native trees and plants possess qualities like thick bark and fire-stimulated flowering, seed release and germination.

When the first European explorers encountered these landscapes, they reportedly marveled at their picturesque, park-like qualities. These qualities were due to Indigenous Peoples managing many of these landscapes with fire over thousands of years. Intentional fire cleared dead and downed woody material, released nutrients into the soil and initiated new growth on which the animals and Indigenous Peoples depended.

Current Conditions

As Sonoma County was settled, wildfires were frequently suppressed. This led to the buildup of large amounts of woody vegetation. In addition, logging often removed the largest trees, leaving regenerating forests to grow into dense stands of trees. Foresters call these “dog-hair thickets” - walls of impenetrable vegetation created by many trees fighting for limited resources. These conditions - along with invasive pathogens like sudden oak death, which kills tan oaks, and drought-related bark beetle outbreaks, which kill vast areas of pine forests - led to the volatile combustibility of local forests.

In addition to these events, climate change has exacerbated fire intensity and severity by increasing daily temperatures and extending the annual dry season. As a result, we now regularly experience catastrophic wildfires in California.

Solutions

There are solutions that can nurture our landscapes back to health. However, it will take time and a commitment to work with the ecological processes that have shaped these landscapes for eons. Our goal is to use prescribed fire as a tool to transform young and dense forests and woodlands into mature, self-sustaining ecosystems reminiscent of the past and resilient to the conditions of tomorrow.

Land Management and Prescribed Fire

Prescribed fire is a vital element that has been missing from our landscapes for over 100 years. It is one of the many tools that can help reduce vegetation (referred to in land management as "fuel loads"), help protect our communities and revitalize our ecosystems. We are implementing a multi-phased approach that includes creating shaded fuel breaks along trails and roads. Shaded fuel breaks clear the understory in wooded areas, creating defensible space for firefighting and control lines for prescribed fires.

Prescribed fire is the purposeful use of fire in an area. It is carefully planned and carried out under specific weather and fuel  moisture conditions called a “prescription”. Prescribed fire reduces the buildup of surface and ladder fuels – which, left untouched, enable fire to climb into the tree canopy and can feed high severity fires that reduce forests to ash. Even with the use of prescribed fire, future wildfires will still occur, but reducing built-up fuel will result in lower-intensity fires. This kind of fire can also help initiate ecosystem processes such as nutrient cycling, seed dispersal, germination, reduction of pathogens and protection of mature trees that will continue to sequester carbon and ultimately help protect adjacent communities.

By managing our landscapes with low-intensity prescribed fire, we will reintroduce an element that can make our parks and our communities more resilient to climate change and future wildfires.
