FIRE ECOLOGY
SPECIES: Rudbeckia hirta | Black-Eyed Susan 



FIRE ECOLOGY OR ADAPTATIONS : 
Black-eyed Susan probably has good fire tolerance in the dormant state,
since it reproduces vegetatively from the root crown [48,56].  It
produces numerous small seeds [11] and can establish on burned sites.
Black-eyed Susan thrives in the open, sunny conditions [31,51] created
by fire.  It may be an initial on-site colonizer since its seeds are
found up to 4 inches (10 cm) or deeper in the seedbank [38].  However,
no information was available on seed tolerance to heat or length of seed
viablility in the seedbank.


POSTFIRE REGENERATION STRATEGY : 
   Initial-offsite colonizer (off-site, initial community)
   Caudex, growing points in soil
