  • Discussion

 

Documenting individual fire intervals can be useful for some purposes, such when documenting the number of years since the last fire in a stand or landscape subjected to long-term fire exclusion.  However, when planning for scheduled prescribed fires or developing fire management plans, most managers and researchers prefer to use metrics that yield longer-term perspectives of fire frequency, such as those provided by the mean fire interval. For further discussion, see Agee 1993, McPherson and others 1990, and Romme 1980.
