FIRE EFFECTS
SPECIES: Artemisia absinthium | Absinth Wormwood 



IMMEDIATE FIRE EFFECT ON PLANT : 
Low-severity fire readily top-kills absinth wormwood and may completely
kill some plants.  Because absinth wormwood perennating buds are at or
near the soil surface, they are susceptible to fire [21].


DISCUSSION AND QUALIFICATION OF FIRE EFFECT : 
NO-ENTRY


PLANT RESPONSE TO FIRE : 
Absinth wormwood perennating buds will sprout if they survive fire.
Annual early spring prescribed fires were conducted in a South Dakota
prairie infested with absinth wormwood.  Dormant fine fuels ranged from
2,000 to 2,400 kilograms per hectare.  Nearly two-thirds of the absinth
wormwood survived the first fire and regrew, but four consecutive annual
spring fires reduced absinth wormwood by 96 percent [21].


DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : 
NO-ENTRY


FIRE MANAGEMENT CONSIDERATIONS : 
Spring fire can reduce absinth wormwood on northern mixed prairie sites
during years with adequate fuel.  However, abundant green herbaceous
material can reduce fire severity during the spring and thus reduce fire
damage to absinth wormwood [21].
