Boggs Demonstration State Forest
Boggs Mountain Demonstration State Forest is a nearly 3,500-acre forest located in southern Lake County, California, about 50 miles inland from the Pacific shoreline and 75 air miles north of San Francisco. CAL FIRE acquired the forest in 1949 after most of the merchantable timber had already been harvested. The forest is characterized by gently rolling terrain bordered by two mountain peaks, and geologically, it is complex, with various types of volcanic rock exposed.
In 2015, the Valley Fire burned through 99% of the forest, killing about 80% of mature trees and 95% of the understory regeneration. Reforestation efforts have included salvage logging operations and the planting of over 700,000 tree seedlings of species such as Ponderosa Pine and Douglas Fir. The forest has a diverse range of vegetation, with manzanita being the most predominant at lower elevations and mixed conifer forest at upper elevations.
The forest is also home to hardwood species such as canyon live oak, black oak, dogwood, and madrone. Hunting is permitted under state game laws, and pets are welcome but must be leashed and controlled.
Area: 3,493 acres
Elevation: 2,400 - 3,750ft
Precipitation: 71in per year
Temperature: Max: 100 F - Min: 13 F

Numerous research projects are underway at BMDSF. Two of the large scale research projects undertaken on BMDSF after the Valley fire are Monitoring Impacts of Fire on Watersheds at Boggs Mountain Demonstration State Forest and Fire Effects, Carbon, and Forest Regeneration. These studies are designed to gather data on the impacts of post-fire recovery strategies. These projects are monitoring the effects of post fire salvage logging and site preparation on post fire recovery.
Boggs Mountain Demonstration State Forest (BMDSF) is open year-round for day use only from sunrise to sunset. Seasonal camping is CLOSED for the season.
Due to excessive litter and damage to forest equipment and natural resources, recreational target shooting, off-roading and Off Highway Vehicle (OHV) use is prohibited on BMDSF. All vehicles must stay on mapped, numbered roads. The complete trail system has not yet been re-established. 2022 completed trails include Bear Bones, Boggs Peak, and Gail’s. Please see the "Trails" section for more information
For public health and safety, forest roads are subject to temporary closure pending wet weather conditions. The forest is patrolled frequently, and violators will be cited. CAL FIRE encourages forest visitors to plan ahead before arriving. Please call the Forest Office at 707-928-4378 for more information.
Please be aware of your surroundings and abide by the Local, State, and Federal laws.
All roads, trails, and structures on and adjacent to Boggs DSF are applicable to Gun Free School Zone Act of 1995 and CDFW code Article 1. Methods of Taking [3000-3087] 3004.
(a) It is unlawful for a person, other than the owner, person in possession of the premises, or a person having the express permission of the owner or person in possession of the premises, while within 150 yards of an occupied dwelling house, residence, or other building, or within 150 yards of a barn or other outbuilding used in connection with an occupied dwelling house, residence, or other building, to either hunt or discharge a firearm or other deadly weapon while hunting. The 150-yard area is a “safety zone.”
(b) It is unlawful for a person to intentionally discharge a firearm or release an arrow or crossbow bolt over or across a public road or other established way open to the public in an unsafe and reckless manner.

BMDSF staff and the Friends of Boggs Mountain (FOBM) nonprofit 501c3 group are currently working on a restoration project to bring back the trail system on BMDSF. Several trail alignments have been restored and are open to hiking, mountain biking and horseback riding only. To prevent trail destruction, motorized vehicles including E-bikes are NOT permitted on the trails.
In 2022, trail crews completed Bear Bones, Boggs Peak, and Gails Trails bringing to a total of approximately 12 miles of trails. These trails offer breathtaking views and go through reforestation plantations after the 2015 Valley Fire. Unauthorized trail construction is not allowed. Be considerate of other users and use proper trail etiquette.
Monitoring Impacts of Fire on Watersheds at Boggs Mountain Demonstration State Forest This study’s objectives are to quantify the impacts of different burn severities on runoff and erosion, assess the impacts of post-fire salvage logging and site preparation on runoff and erosion, and to assess processes that control post-fire and post-salvage erosion
Fire Effects, Carbon, and Forest Regeneration - The research and goals associated with this study are divided into two phases, where the first phase is based on an observational study involving data collection from the CFI permanent plots established throughout the forest. This analysis forms the basis for estimating direct impacts of the fire on vegetation, fire hazards, and carbon stocks. A second phase of research is based on a manipulative experiment looking at the influence of salvage logging and site preparation techniques on post-fire forest recovery.
