FIRE ECOLOGY
SPECIES: Spiraea douglasii | Douglas' Spirea 



FIRE ECOLOGY OR ADAPTATIONS : 
Douglas' spirea is moderately resistant to fire [32] and sprouts readily
from the stem base and rhizomes after fire [4,17,29,32].  In
presettlement times, wildfires were "probably common" in Douglas' spirea
communities of riparian areas in Montana and Oregon; soils were usually
dry by mid-summer, allowing fires from adjacent uplands to encroach upon
the stand [17,29].  Fires were probably infrequent in the thinleaf
alder-Douglas' spirea association in Oregon [29].


POSTFIRE REGENERATION STRATEGY : 
   Small shrub, adventitious-bud root crown
   Rhizomatous shrub, rhizome in soil
