FIRE ECOLOGY
SPECIES: Alnus viridis ssp. sinuata | Sitka Alder 



FIRE ECOLOGY OR ADAPTATIONS : 
Sitka alder generally sprouts from the root crown following fire
[16,47,52].  Numerous wind-dispersed seeds are produced by off-site plants
and on-site plants which sprout following fire.  Sitka alder's frequency
and extent increase rapidly in early successional communities following
fire [47,52].

Fire tends to occur infrequently on the moist sites occupied by Sitka
alder communities [10].  The nonflammable bark and nonresinous leaves
protect alders somewhat from low intensity fires [10].


POSTFIRE REGENERATION STRATEGY : 
   survivor species; on-site surviving root crown or caudex
   off-site colonizer; seed carried by wind; postfire years one and two
