The loss of oak woodlands to native conifer encroachment is a major conservation concern in California, resulting in associated losses of wildlife habitat, traditional uses, biodiversity, and other ecosystem services. These concerns – compounded by development pressures, evolving understanding of fire’s role in California landscapes, and health threats like sudden oak death – have drawn increasing attention in recent years, and oak woodland conservation and restoration efforts have gained momentum.
