FIRE ECOLOGY OR ADAPTATIONS
POSTFIRE REGENERATION STRATEGY

FIRE ECOLOGY OR ADAPTATIONS:

Fire adaptations: Gray horsebrush is a fire resistant shrub [59] that is only briefly harmed by burning [24,28]. After a fire the plant responds by rapid sprouting from adventitious buds on the root crown, well below the soil surface [15,24,28,59,66]. A single burned gray horsebrush shrub may produce as many as 5-7 sprouts [66], which may appear to be entirely new plants [15]. In addition, the plant reproduces abundantly from a heavy seed crop following fire [42,69]. These postfire responses often result in dense stands of gray horsebrush [15] and can result in dominance by gray horsebrush in sagebrush-grass communities that are burned with a frequency of 20-25 years [64].

Fire regimes: Fire regimes for plant communities and ecosystems in which gray horsebrush occurs are summarized below. For further information regarding fire regimes and fire ecology of communities and ecosystems where gray horsebrush is found, see the 'Fire Ecology and Adaptations' section of the FEIS species summary for the plant community or ecosystem dominants listed below.

POSTFIRE REGENERATION STRATEGY [52]:

Tall shrub, adventitious bud/root crown
Initial off-site colonizer (off-site, initial community)
Secondary colonizer (on-site or off-site seed sources)
