Potential State Changes Related to Drought, Fire and Grazing
Illustration 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).
