FIRE EFFECTS

SPECIES: Purshia glandulosa | Desert Bitterbrush

IMMEDIATE FIRE EFFECT ON PLANT:


Desert bitterbrush is considered fire tolerant [1,22,29]. Plants sprout in response to being top-killed, but can be killed if heat is sufficient to kill the root crowns [10,18,45].

DISCUSSION AND QUALIFICATION OF FIRE EFFECT:


No entry

PLANT RESPONSE TO FIRE:


Desert bitterbrush often sprouts vigorously following fire [6,8,28], even in dry conditions [7]. Even root crowns charred below the surface have sprouted [28]. In some studies, however, desert bitterbrush has been killed by fire [10,18,45]. The fire literature does not specify whether the decumbent or erect form of desert bitterbrush is more susceptible to fire.

Stem layering is another response to fire if heat has not killed all aboveground tissue. Layering following fire is particularly evident on burned-over areas with finer-textured rather than coarse-textured soils [28].

Following spring prescribed burns near Ely, Nevada, mean rodent desert bitterbrush seed cache densities were significantly (p=0.05) higher within the burned areas than outside. Only 2 desert bitterbrush sprouted following these prescribed burns, and they lacked vigor and died the spring following the fires. The presence of large numbers of rodent caches may result in the continued presence of desert bitterbrush on the site [45].

DISCUSSION AND QUALIFICATION OF PLANT RESPONSE:


No entry

FIRE MANAGEMENT CONSIDERATIONS:


Fall mortality of desert bitterbrush following fire is higher than after spring burns [6,7,18].
