FIRE ECOLOGY
SPECIES: Cirsium neomexicanum | Lavender Thistle 



FIRE ECOLOGY OR ADAPTATIONS : 
Regeneration of lavender thistle after fire is not described in the
available literature.  However, it probably can colonize burned areas
via seeds.

Fire frequency in the communities where lavender thistle occurs is
generally low.  In creosotebush scrub communities, fires generally occur
only in years when exceptionally heavy winter rains have produced
abnormally high numbers of annuals.  Fires are also rare in blackbrush
communities; however, these communities have been known to burn under
conditions of high temperature, high wind velocity, and low relative
humidity.  Shadscale communities rarely burn [7].  Pinyon-juniper
communities historically burned every 10 to 30 years.  Where livestock
grazing has reduced grass cover and accelerated erosion, fire frequency
has decreased [20].
