Mechanism
This transition occurs after decades of little to no disturbance (including management) which results in a build up of fuels. A high severity, stand replacing fire may then trigger an abrupt change to the vegetation composition and structure. Shrubs adapted to the new fire regime, sprout and seed at a much higher rate than the tree component, leading to a shrub chaparral state. Alternatively, drought driven losses of conifers (i.e. western pine beetle) can cause this transition to occur.
Mechanism
This transition occurs after active brush management and enough browsing/grazing pressure to eliminate the woody vegetation.
Mechanism
This restoration pathway occurs after active brush management, chemical treatment, followed up with tree planting.
Mechanism
This transition occurs after active brush management (and/or failed tree plantings) and enough browsing/grazing pressure to maintain an open shrub free system.
