Forest Practice

The California Department of Forestry and Fire Protection (CAL FIRE) enforces the laws that regulate logging on privately-owned lands in California. Forest Practice Act which was enacted in 1973 to ensure that logging is done in a manner that will preserve and protect our fish, wildlife, forests and streams. Additional rules enacted by the State Board of Forestry and Fire Protection are also enforced to protect these resources.

CAL FIRE ensures that private landowners abide by these laws when harvesting trees. Although there are specific exemptions in some cases, compliance with the Forest Practice Act and Board rules apply to all commercial harvesting operations for landowners of small parcels, to ranchers owning hundreds of acres, and large timber companies with thousands of acres.

The Timber Harvesting Plan (THP) is the environmental review documents submitted by landowners to CAL FIRE outlining what timber he or she wants to harvest, how it will be harvested, and the steps that will be taken to prevent damage to the environment. THPs are prepared by Registered Professional Foresters (RPFs) who are licensed to prepare these comprehensive, detailed plans. THPs can range from about 100 pages to more than 500 pages.

CAL FIRE does not have the authority to deny a THP that is in compliance with state and federal rules and laws, simply because the logging plan is unpopular with the public. The Department reviews and approves between 500 to 1400 THPs each year. A THP that does not comply with all forestry and environmental regulations is returned to the RPF. It is only approved after the RPF and landowner agree to make the changes necessary to ensure compliance with all laws. CAL FIRE follows-up on approved THPs with site inspections and can shutdown operations, cite or fine Registered Professional Foresters, Licensed Timber Operators (LTOs), and landowners if illegal operations are found.

Gray Wolves (Canis lupus) in California Timber Harvesting Plans
May 6, 2015
The gray wolf (Canis lupus) was listed as endangered under the California Endangered Species Act (CESA) by the California Fish and Game Commission on June 4, 2014. Given that gray wolves have been reestablished in southern Oregon, they may begin to become reestablished on public and private timberlands in northern California.  For purposes of timber harvesting plan preparation, the gray wolf listing under CESA should be acknowledged in the THP.  Furthermore, consultation with CDFW is recommended when presence of wolves is known or wolf den and/or rendezvous sites have been identified.  Further information can be found on the CAL FIRE webpage at:

New Timber Harvesting Plan Form - RM-63 (03/15)

The THP form has been revised as a result of changes to the rules, including the new "Road Rules", which are now in effect as of January, 2015. Changes are reflected in the content of the 38 Items listed in Sections I and II of the form. There has been no reorganization of the Item numbers themselves. The revisions and additions address rules that, when applicable, are required to be addressed in the plan. In addition, the THP form has been updated and revised for clarity and ease of use. Comments related to the contents and use of new form should be directed to Bill Solinsky (

The check boxes incorporated in the form can be "checked" by clicking on the box, if your computer software allows. Otherwise, you may mark the box as you have in the past. The form also includes various colored "fonts" to assist you in identifying which questions apply, relative to the watershed(s) the plan is located in:

  • Information and questions in "Black" apply to all plans.
  • Information and questions in "Red" apply to plans in Non ASP and exempt ASP watersheds.
  • Information and questions in "Blue" apply to plans in ASP Watersheds &/or Immediately upstream.
  • Rule citations will be found in "black" if they are incorporated as part of a question.
  • Rule citations in "green" are identified to assist plan preparers in locating the pertinent rule.

The new THP form can be found at the following link, located on the Department 's website:

Important information on the Sierra Nevada mountain yellow-legged frog (Rana sierrae) and the northern distinct population segment of the mountain yellow-legged frog (Rana muscosa)

On April 29, 2014 the U.S. Fish and Wildlife Service (USFWS) published the final rule listing the Sierra Nevada yellow-legged frog and the northern distinct population segment (DPS) of the mountain yellow-legged frog as endangered; the final rule becomes effective on June 30, 2014. Guidance for RPFs and LTOs to follow.

REVISED ASP Q and A Document Available with Class II-L Changes

The document titled "Anadromous Salmonid Protections Rules: Revised Interpretive Questions and Answers for RPFs and Landowners" has been posted at the following: QA doc with revised language 06_16_14 (final revision).pdf This revision of the document that was produced in April of 2010 reflects changes made by the Board of Forestry and Fire Protection when they passed the "Class II-L Identification and Protection Amendments, 2013" rule package, which went into effect January 1, 2014.

A petition to list Townsend’s big-eared bat (Corynorhinus townsendii) (COTO) as Threatened or Endangered under the California Endangered Species Act (CESA) was received by the California Fish and Game Commission (Commission) on November 1, 2012. On June 26, 2013, the Commission voted to designate COTO as a candidate for listing. Starting on the date it officially becomes a candidate, COTO will receive the same legal protections under CESA as a threatened or endangered species, including the general prohibition on “take” of such species. You may consider including an analysis and appropriate mitigation measures in your timber harvesting plan (THP) prior to the date it officially becomes a candidate in order to avoid amendments to your THP in the future.

The range of the COTO extends throughout the State. COTO primarily roosts in caves, mines, abandoned dwellings, and large basal hollows of trees. The Biological Impacts section of your proposed harvesting plan should include a discussion of COTO (life history, threats, available habitat and appropriate mitigation) if the proposed timber operations may result in a significant adverse impact, cumulative impact, or take, once the species candidacy is formally announced. Proposed avoidance and mitigation measures should be included under Section II, Item 32a of the Plan if appropriate.

For more information; the evaluation of the petition to list, a life history account, and a range map can be viewed by going to the following web site and searching for “Townsend’s big-eared bat”.

As an alternative to presenting information pertaining to map points in various places throughout timber harvesting documents, the following Map Point Reference Table and Key is a suggested framework for addressing map points in Timber Harvesting Plans (THPs), Nonindustrial Timber Management Plans (NTMPs), and Notices of Timber Operations (NTOs).

Developed in collaboration with various Regional Water Quality Control Boards, the California Department of Fish and Wildlife, and the Department of Conservation‐‐California Geological Survey; the table has been designed to eliminate the need to repeatedly provide the same information separately for THPs/NTMPs, Erosion Control Plans, and 1600 applications and can be used for all map points that are required to be identified and described (e.g. unstable areas, exceptions and in lieu points, watercourse crossings, mitigations sites, etc.).

The Table and Key have been prepared as an alternative tool, to assist registered professional
foresters who prepare plans; and can be found at the following link, located on the CAL FIRE’s

Important Information on Pacific Fisher and Timber Operations

On November 7, 2012, the California Fish and Game Commission, pursuant to Court Order, set aside its September 15, 2010 rejection of the petition to list the Pacific fisher (Martes pennanti) as threatened or endangered under the California Endangered Species Act (CESA). This means that the Pacific fisher is a candidate species under CESA. Candidate species are protected against take per the Fish and Game Code. Anyone conducting timber operations within the range of the Pacific fisher should go to the following link and look at the documents posted under Pacific Fisher for important information:

Non-industrial Timber Management Plans: Information for Registered Professional Foresters related to Water Quality and Cumulative Impacts

CAL FIRE has posted a memorandum, which is intended to provide clarification regarding the difference in noticing requirements described in the Forest Practice Act and Rules under PRC § 4594(g) and 14 CCR § 1090.7(h) and (i) for notices of timber operations under a non-industrial timber management plan, and how the cumulative impact assessment evaluation area melds with the North Coast Regional Water Quality Control Board's waste discharge requirements and waivers of waste discharge requirements when considering the beneficial uses of water ( Understanding this relationship is important to avoid confusion by registered professional foresters, the public, and review agency staff.
