- Incidence of BF usually greatest during Spring & Fall
- BFU’s assigned to SIBC staffed independently on 9x6 tours, March 17 thru April 30 AND Oct. 17 thru Nov. 30

Weather is the controlling factor affecting severity & incidence of BF.
Serious BF conditions occur when the following weather conditions are present:
3.2.1
Low humidity
Winds in Excess of 15 mph
Little or no rainfall for preceding 3 days or more. The longer the period w/o rain, the greater the hazard.
Preplanning

- Require burrowing holes in bog, inserting homeliness & flooding, using large amts. of water BEYOND SATURATION
Crown Fires
3.4.3
