Fuel Reduction and Cultural Resources

National parks conduct prescribed burns and mechanical fuel reductions to reduce the amount of combustible material within park boundaries. Prescribed burns are fires intentionally set and allowed to burn within a designated area. Mechanical fuel reductions refer to the manual or machine removal of fuels from a designated area. Prescribed burns and mechanical fuel reductions intentionally reduce the fuel load to prevent or minimize the effects of wildfires.

Careful planning can result in a fuel reduction project that mutually benefits the wildland fire program and cultural resource program. This section of Cultural Resources and Fire provides guidance to ensure that planning and implementation of fuel reduction projects comply with Federal cultural resource laws and policies, and Executive Order 13175. The guidance is aimed at wildland fire program managers; cultural resource managers; park superintendents; and Section 106 coordinators.

Planning Fuel Reduction Projects

Planning for fuel reduction projects begins with the park’s wildland fire management plan. Parks schedule fuel reduction activities 5-10 years in advance and include them in the plan. The list of proposed fuel reduction projects is updated as projects are completed and new ones are added. Each year, the park prioritizes the fuel reduction activities for that year. The national program coordinates fuel reduction activities between agencies and distributes a list of targeted activities for that year. Depending on weather and other local conditions, this list may change. Wildland fire management plans must address management of cultural resources at risk during the prescribed burn or mechanical fuel reduction activity.

Fuel Reduction and Compliance with Federal Laws, Policies, and Executive Orders

Wildland fire management plans for fuel reductions are Federal undertakings and, as such, must comply with Federal cultural resource laws and policies, and Executive Order 13175.

Essential elements of compliance for fuel reductions include:

  • Completion of an inventory of significant cultural resources at risk of adverse effects from the fuel reduction activity;

  • Sharing information with stakeholders in consultation; and

  • Documentation that stakeholders’ comments and concerns have been taken into consideration before implementing the proposed project.

Compliance with Federal cultural resource laws and policies, and Executive Order 13175 includes consultation to share and elicit cultural resource information and demonstration that comments and concerns have been taken into consideration when planning and implementing fuel reduction projects.

Consultations take place when the fuel reduction project is proposed, and may be held again just prior to implementation. Consultations with federally-recognized Indian tribes are conducted on a government-to-government basis and cannot be delegated to any nonfederal entity.

More information is available in Fire Management and Cultural Resource Laws.
Assistance for planning and implementing consultations is available in Consultation for Compliance with Federal Laws.

Developing Cultural Resource Inventories for Fuel Reduction Projects

NHPA and NEPA compliance stipulates that all significant cultural resources that may be adversely affected by the proposed fuel reduction project be identified and assessed prior to initiation of the project. The effects of a fuel reduction activity on cultural resources depend on characteristics of the resources and of the method used to remove the burnable fuel. Mechanical fuel reductions may have little effect on historic structures but may have an effect on archeological resources. Proposed burns may have little effect on archeological resources, but have the potential for effects on historic structures. The direct and indirect effects of burning fuel depend on the size and height of the fuel, the moisture content, and other factors.

Implementing the Fuel Reduction Plan

The wildland fire program manager notifies the cultural resource manager of the dates of any fuel reduction activity. The wildland fire program manager and the cultural resource manager coordinate to ensure that all cultural resource avoidance or treatment measures are in place. Care is taken to ensure that the project does not exceed the APE.

Safety

Employee and public safety is the first priority in every management activity. All planning and implementation activities must reflect this commitment. A job hazard analysis should be prepared for each incident activity.

After Completion of Fuel Reduction Projects

Mechanical fuel reductions and prescribed burns protect cultural resources by removing burnable fuels from the vicinities of historic properties. These fuel reduction projects may also remove ground cover, and make the ground surface more vulnerable to looting and erosion, which affects the integrity of cultural resources. Periodic inspection of the affected APE is carried out to determine whether looting or erosion is occurring.
