FIRE EFFECTS
SPECIES: Spiraea douglasii | Douglas' Spirea 



IMMEDIATE FIRE EFFECT ON PLANT : 
Douglas' spirea is probably topkilled by most fires and killed by
severe fires.


DISCUSSION AND QUALIFICATION OF FIRE EFFECT : 
NO-ENTRY


PLANT RESPONSE TO FIRE : 
The literature contains few reports describing Douglas' spirea after
fire.  Because of its sprouting ability, it probably survives most
fires.  In central British Columbia Douglas' spirea was present with
shinyleaf spirea (Spiraea betulifolia var. lucida) in seral Engelmann
spruce (Picea engelmannii)-fir (Abies spp.) stands.  Relative density of
the Spiraea spp. in plots 4 to 22 years after fire was 4 percent; in
plots 37 to 75 years after fire, it was 9 percent [13].  In British
Columbia McMinn [38] studied a site in a western hemlock/Sitka spruce
forest burned in 1861 and again in 1931.  By 1948 Douglas' spirea had
formed dense thickets with salmonberry and thimbleberry.


DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : 
NO-ENTRY
