Fire threat provides a measure of fuel conditions and fire potential in the ecosystem, representing the <\/SPAN><\/P>

relative likelihood of \u201cdamaging\u201d or difficult to control wildfire occurring for a given area. Fire Threat is <\/SPAN><\/P>

not a risk assessment by itself, but can be used to assess the potential for impacts on various assets <\/SPAN><\/P>

and values susceptible to fire. Impacts are more likely to occur and/or be of increased severity for the <\/SPAN><\/P>

higher threat classes.<\/SPAN><\/P>

Fire threat is a combination of two factors: 1) fire probability, or the likelihood of a given area burning, <\/SPAN><\/P>

and 2) potential fire behavior (hazard). These two factors are combined to create 5 threat classes ranging <\/SPAN><\/P>

from low to extreme.This version (fthrt14_2) is an update created from fthrt14_1 (created for the <\/SPAN><\/P>

FRAP 2017 Forest and Rangeland Assessment). Fire Rotation data in fthrt14_1 was replaced with <\/SPAN><\/P>

Annual Fire Probability data. <\/SPAN><\/P>
