Service Description:

Fire Threat is a combination of two factors: 1) fire probability, or the likelihood of a given area burning, and 2) potential fire behavior (hazard). These two factors are combined to create 5 threat classes ranging from low to extreme.

This version (fthrt14_2) is an update created from fthrt14_1 (created for the FRAP 2017 Forest and Rangeland Assessment). Fire Rotation data in fthrt14_1 was replaced with Annual Fire Probability data developed for California by Pyrologix Inc.

Description:

Copyright Text: California Department of Forestry and Fire Protection (CAL FIRE) - Fire and Resource Assessment Program (FRAP) Annual fire probability data for California was developed and provided to CAL FIRE by Joe Scott, Pyrologix Inc. Fuel Rank data was developed in 2005 by CAL FIRE-FRAP, and updated for 2014 using the FRAP California Interagency Fire Perimeter Database (fire16_1). CAL FIRE recognizes the various partners that have contributed to this dataset, including USDA Forest Service Region 5, USDI Bureau of Land Managment, National Park Service, National Fish and Wildlife, and numerous local agencies. Existing vegetation data used in formulation of Fire Threat were from the FRAP Existing Vegetation dataset, which was developed in cooperation with California Department of Fish and Wildlife VegCamp program and the USDA Forest Service Region 5 Remote Sensing Laboratory (RSL).

Title: Fire Threat in California HVT
Author: hvantas1_UWyo
Comments:
Subject: Fire Threat provides a measure of fuel conditions and fire potential in the ecosystem, representing the relative likelihood of “damaging” or difficult to control wildfire occurring for a given area. Fire Threat is not a risk assessment by itself, but can be used to assess the potential for impacts on various assets and values susceptible to fire. Impacts are more likely to occur and/or be of increased severiety for the higher threat classes.
