IMMEDIATE FIRE EFFECT ON PLANT:

Fire usually top-kills galleta, leaving rhizomes relatively intact [56].

DISCUSSION AND QUALIFICATION OF FIRE EFFECT:

No entry

PLANT RESPONSE TO FIRE:

Galleta resprouts from rhizomes following fire, achieving or exceeding preburn cover within 2 years [56]. Galleta decreases after wildfire during below-average years of precipitation [101].

DISCUSSION AND QUALIFICATION OF PLANT RESPONSE:

During a year of below-average precipitation, galleta decreased in the first year after spring (April) fire within a pinyon-juniper habitat of New Mexico [25].

In the Great Basin, burning had no effect on galleta seedling emergence but was correlated with seedling survival. Significantly (p<0.05) greater seedling survival occurred on unburned areas [49].

FIRE MANAGEMENT CONSIDERATIONS:

Galleta is most susceptible to fire during periods of low humidity [56]. Fire, during years of below normal precipitation, generally reduces galleta within shortgrass prairies [48].

Prescribed burning in winter may prove less deleterious. Jameson [55] found that galleta survived higher temperatures during winter than summer burns in pinyon-juniper habits of Arizona. Fatal temperatures ranged from 135.5 to 142.2 degrees Fahrenheit (57.5-61.2 ēC) in the summer (July-September) and averaged 155.48 degrees Fahrenheit (68.6 ēC) in the winter (November-December).
