FIRE ECOLOGY
SPECIES: Abies amabilis | Pacific Silver Fir 



FIRE ECOLOGY OR ADAPTATIONS : 
In the Pacific silver fir zone, fires are infrequent (fire interval is
500 years) because of the humidity and the high levels of precipitation.
Surface fires are usually of low severity [69].  Some stands of Pacific
silver fir show no evidence of having burned.  Fire frequency is a
limiting factor in the range of Pacific silver fir [69].  Pacific silver
fir is a fire-avoiding species throughout all stages of its life [72].
It is extremely fire sensitive primarily because its thin bark and
shallow roots [26].  Its foliage is highly flammable [50].  The mean
fire interval for Pacific silver fir as a primary dominant is 192 years
[1].
