Hazard Tree Program

Providing support and guidance on hazard tree issues is an integral part of the Forest Health Protection program at each of the four FHP Shared Service Area offices in Region 5. Guidance from the R5 Regional Pesticide Use Specialist is crucial as well. Assistance to our partners takes many forms, including:

  • Providing guidance in hazard tree identification and assessment procedures and vegetation management in developed recreation areas and along National Forest system roads.
  • Providing training and “train the trainer” opportunities in hazard tree identification and management.
  • Assisting and supporting the development and implementation of vegetation management plans for developed recreation areas.
  • Monitoring developed recreation areas for tree hazard.
  • Educating Forest Service personnel on the Regional direction for application of borate fungicide on stumps to prevent Heterobasidion root disease.
  • Providing assistance to Forest Service law enforcement and the Office of General Council in the investigation and litigation of incidents associated with tree failures.

Current Issues, Situation, Accomplishments

  • Regional guidelines for the identification and management of hazard trees in recreation areas and along roads are currently being developed. Area-specific guidelines have been developed for some National Forests.
  • Hazard Tree Identification and Management is part of the curriculum in the Regional Forest Pest Recognition and Management training.
  • Hazard Tree training is available upon request from FHP. In the last five years, it has been provided at Whiskeytown NRA, Lassen Volcanic NP, and on the Shasta-Trinity, Klamath, Lassen, Plumas, and San Bernardino NFs.
  • FHP provided support and guidance for vegetation management in a variety of developed recreation areas, including 4 campgrounds at Whiskeytown NRA, and 23 sites on National Forests.
  • Region 5 FHP provided the lead for the Western International Forest Disease Work Conference (WIFDWC) Hazard Tree Workshops in Midway, UT since the first one in Visalia in 1995. Planning for the 2013 Workshop is now underway.
  • Region 5 Pathologists have chaired the WIFDWC Hazard Tree Committee since the committee’s establishment in 1994.
  • FHP assisted Forest Service law enforcement and the Office of General Council in assessing the causes of multiple fires and in a fatality investigation, all involving hazard trees. Expert witness testimony was also provided during subsequent litigation.
