Shrub expansion

Description: 

Explanations for unsuccessful attempts to limit shrub expansion using various methods, including livestock removal, have emerged from JRN studies. Current dominance by creosotebush of this exclosure (right panel) built in 1920 on a site dominated by black grama grasslands (left panel) is attributed to spatial processes of redistribution of water, nutrients, and seeds across scales that overwhelmed effects of release from grazing on grass-shrub competition.
