FIRE EFFECTS
SPECIES: Aster conspicuus | Showy Aster 



IMMEDIATE FIRE EFFECT ON PLANT : 
Showy aster is top-killed by fire.  Because rhizomes often survive, the
species has been classified as moderately resistant to fire [8].


DISCUSSION AND QUALIFICATION OF FIRE EFFECT : 
NO-ENTRY


PLANT RESPONSE TO FIRE : 
Showy aster increases rapidly after fire [16,18].  Showy aster exhibits
mass flowering in postfire years 1 and 2.  The extent of flowering is
directly related to preburn abundance and postfire survivorship
[22,23,24].  Showy aster frequency increased from 8 percent before fire
to 20 percent 2 years after a moderate-severity fire in a Douglas-fir
forest in Idaho.  By postfire year 7, showy aster frequency increased to
52 percent [16].  Following the 1977 Pattee Canyon Fire in Missoula,
Montana, showy aster cover was 1.4 percent in 1978 and 2.0 percent in
1982 [16].


DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : 
NO-ENTRY


FIRE MANAGEMENT CONSIDERATIONS :
