Pretreatment tree dominance and conifer removal treatments affect plant succession in sagebrush communities

View paper.

This study found that to retain the shrub, especially sagebrush, components on a site and increase ecosystem resilience and resistance through increases in tall grasses, treatment should occur at low to mid tree dominance index (TDI) using mechanical methods, such as cutting or mastication. Effects of fire and mechanical treatments implemented at different phases of tree dominance create different successional trajectories that could be incorporated into state-and-transition-models to guide management decisions.
