FIRE EFFECTS
SPECIES: Artemisia dracunculus | Tarragon 



IMMEDIATE FIRE EFFECT ON PLANT : 
Tarragon is easily top-killed by low-intensity fires.  The presence of
underground rhizomes suggests that the majority of individuals are
somewhat resistant to fire mortality.


DISCUSSION AND QUALIFICATION OF FIRE EFFECT : 
NO-ENTRY


PLANT RESPONSE TO FIRE : 
Limited fire response data for tarragon indicates that preburn densites
are regained immediately following burning.  Dix [5] conducted burns on
sandy upland sites in the mixed-grass prairie of North Dakota.  He
reported that tarragon frequencies on burned sites equaled those on
unburned sites in less than 3 months after a spring burn [5].  On
similar sites tarragon increased substantially within 4 years of a late
August burn.  Dix suggested that tarragon was able to increase
dramatically due to the loss in vigor of associated species.  It is
unclear whether increases in tarragon frequencies resulted via the
germination of off-site seed, from seedlings established via on-site
residual plants, or from rhizome sprouting.


DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : 
NO-ENTRY


FIRE MANAGEMENT CONSIDERATIONS : 
NO-ENTRY
