Potential State Changes Related to Drought, Fire and Grazing
Potential State Changes Related to Drought, Fire and GrazingIllustration of potential state changes related to drought, fire and grazing. Native grassland sites (1) can transition (A) to non-native dominated (2) when the fire regime is altered and grazing occurs. Re-introduction of fire (B) can help restore native grasses and reduce woody plant cover (3), especially with optimal timing and amount of precipitation (C, 1).
