FIRE EFFECTS

SPECIES: Eriodictyon californicum | Yerba Santa
IMMEDIATE FIRE EFFECT ON PLANT : Moderate-severity fire top-kills yerba santa; severe fire may kill it. Survival of underground rhizomes is most likely after low- to moderate-severity fire [28]. DISCUSSION AND QUALIFICATION OF FIRE EFFECT : NO-ENTRY PLANT RESPONSE TO FIRE : Yerba santa germinates from seed during the first postfire growing season. Seeds that have lain dormant in the soil for decades will germinate following a fire [6]. It is possible that yerba santa has hard-coated seeds that will not germinate except when scarified. Yerba santa seeds are very difficult to germinate under laboratory conditions [14]; and may have some mechanism that inhibits water imbibition and germination. Alternatively, fire may break the seed's dormancy by burning off the litter layer and exposing the seed to sufficient light to allow germination. Newly established seedlings grow rapidly, and may begin vegetative reproduction in the second postfire growing season [6]. Yerba santa sprouts from surviving rhizomes at the first postfire growing season [19]. DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : NO-ENTRY FIRE MANAGEMENT CONSIDERATIONS : Range: Repeated prescribed fires are not recommended for eradicating yerba santa. Eepeated rangeland fires have increased yerba santa populations and decreased the number of desirable browse species. The combination of fire and herbivory removes competing species. If fire is to be used as a management tool, a single fire is recommended to top-kill existing plants; thereafter herbicides should be used to kill sprouts and seedlings [6,19].
