FIRE ECOLOGY
SPECIES: Bouteloua barbata var. barbata | Sixweeks Grama 



FIRE ECOLOGY OR ADAPTATIONS : 
Sixweeks grama often occupies desert sites where vegetation is too
scarce to carry fire [12].  However, in some years rainfall is
sufficient in deserts to produce an abundance of summer annuals which
can easily carry fire.  Sixweeks grama also occurs in semidesert
grasslands dominated by black grama, tobosa grass, or other perennial
grasses of the Southwest.  These grasslands readily carry fire.

Sixweeks grama seeds appear to be long-lived, and large numbers may be
stored in the soil [28,29].  The relatively low temperatures produced by
grassland fires probably do not harm sixweeks grama seeds [16].
Following fire, surviving seeds remain dormant until germination
requirements are met.


POSTFIRE REGENERATION STRATEGY : 
   ground-stored residual colonizer; seed on-site in soil
