Mechanism
This transition occurs after repeated high severity fires or combination of mechanical clearing and grazing, resulting in loss of tree and shrub component.
Mechanism
This transition occurs after tand replacing fire in areas where closed shrublands are establishing. Higher rates of survival of drought tolerant shrubs such as whiteleaf manzanita (which can withstand very low water potentials) and ceanothus, than the oak component leads to chaparral communities.
Restoration pathway R2.a
Mechanism
This restoration pathway occurs with oak planting (natural regeneration events are episodic & rarely occur). Low intensity fire can also result in re-sprouting of oaks.
Mechanism
This transition occurs after seed source of chaparral shrubs is established from adjacent sites.
Restoration pathway R3.a
Mechanism
This restoration pathway occurs with tree planting, often requires shade screens, and seedling protection from browsers to be successful. This also may require brush management to reduce chaparral component
