FIRE ECOLOGY OR ADAPTATIONS
POSTFIRE REGENERATION STRATEGY

FIRE ECOLOGY OR ADAPTATIONS:

Effect of fire on green needlegrass depends on season of burn and site characteristics [144]. Depending on the phenological state of the plant, green needlegrass increases or decreases following fire [80,144]. Aboveground vegetation of green needlegrass is usually consumed by fire, but individual culms may survive [36]. Regeneration is through seed and tillering [143]. The effects of fire, increases in growth or decreases in vigor, can be immediate and last up to 3 years following the fire [33,40,81,103,105,141]

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