FIRE EFFECTS
SPECIES: Cardaria draba | Heart-Podded Hoary Cress 



IMMEDIATE FIRE EFFECT ON PLANT : 
Heart-podded hoary cress is probably top-killed by fire.  


DISCUSSION AND QUALIFICATION OF FIRE EFFECT : 
NO-ENTRY


PLANT RESPONSE TO FIRE : 
Heart-podded hoary cress probably sprouts from rhizomes and establishes
from seed after fire.  At the John Day Fossil Beds National Monument in
Oregon, prescribed fires were conducted in the fall of 1987 and the
spring of 1988 in basin big sagebrush-bluebunch wheatgrass communities.
Heart-podded hoary cress was not present in the prefire communities, but
appeared in trace amounts on the fall burn and at 2 percent in 1989 on
spring burn [27].  Because of its rapid growth, heart-podded hoary cress
may be favored by severe fires that temporarily reduce competition from
native species.


DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : 
NO-ENTRY


FIRE MANAGEMENT CONSIDERATIONS : 
If soils are disturbed by severe fire or by fire suppression activities,
heart-podded hoary cress may be favored.
