FIRE ECOLOGY
SPECIES: Amaranthus retroflexus | Rough Pigweed 



FIRE ECOLOGY OR ADAPTATIONS : 
Rough pigweed seeds are an important part of the seedbank in many
habitats, even when plants are almost absent [16].  As an obligate
initial community species, rough pigweed needs bare, disturbed sites in
order to establish [26,38].  A fire which clears away competing
vegetation can allow the establishment of rough pigweed.

Rough pigweed seeds are very small [14], and easily blown by the wind
from off-site sources.  Some seeds survive cattle digestion [4], and can
be carried by animals to burned areas.


POSTFIRE REGENERATION STRATEGY : 
   Ground residual colonizer (on-site, initial community)
   Initial-offsite colonizer (off-site, initial community)
