Just glanced at the report. According to the abstract, it self extinguishes if the tree is not allowed to dry and and maintains a moisture content in the needles in excess of 100%. How does one exceed 100%?
The fire size for a dry tree was 3.2MW to 4.3MW with the needles consumed within 60 seconds. I remember the tree I fired-up in the backyard as a kid went off like gasoline and gone in like 30 seconds. Nonetheless, the fire size for most of us would be much bigger cause the study used a fairly small tree about 6 ft tall. Good to see that a residential sprinkler contained such an aggressive fire.
