FIRE EFFECTS

SPECIES: Lycium torreyi | Torrey Wolfberry
IMMEDIATE FIRE EFFECT ON PLANT : Severe fires may kill Torrey wolfberry, but low- to moderate-severity fires probably only consume its aerial portions. DISCUSSION AND QUALIFICATION OF FIRE EFFECT : NO-ENTRY PLANT RESPONSE TO FIRE : Specific information on the response of Torrey wolfberry to fire is not available in the literature. In general, wolfberry species sprouted rapidly after controlled June fires in Sonoran Desert scrub vegetation near Phoenix, Arizona. The well developed wolfberry root systems escaped damage from the fire, allowing them to capitalize on increased water and nitrogen availablity in the postfire environment. Wolfberries had established their former density and cover by 35 months after the fire. Wolfberry plants had similiar responses in both open shrub and tree microhabitats [16]. Wolfberry species sprouted and seedlings established within 3 years following a June wildfire in a Sonoran Desert scrub community near Phoenix, Arizona. No information was given on fire severity or intensity [21]. Berlandier wolfberry was reduced by prescribed fires in southern Texas [2,3,7], but the effects were short-lived and canopy diameter had recovered to prefire levels by the end of the first growing season following the fire [7]. DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : NO-ENTRY FIRE MANAGEMENT CONSIDERATIONS : Fires are not prevalent in many desert communities due to wide spacing between shrubs and sparse ground cover [4,10]. Unusually heavy winter rains, however, may produce a cover of annual species dense enough to carry a fire when cured [10]. Many perennial desert shrubs are poorly adapted to fire [4]. Wolfberries in particular may be susceptible to repeated burning [16]. Postfire colonization by desert shrubs is very slow initially and may take hundreds of years [4,21]. Rogers and Steele [21] suggested a conservative approach when using fire to manage desert regions.
