The benefits of oak woodland restoration can exceed the costs of treating conifer encroachment

Woody encroachment is a common threat in many fire-dependent ecosystems throughout the world. In northwestern California, conifer encroachment threatens the survival of deciduous oak woodlands and rangeland habitats, resulting in many negative impacts to flora and fauna biodiversity and livestock production. This study characterizes the benefits and costs of oak woodland restoration projects where Douglas fir is removed, weighing the timber value of the encroaching Douglas fir trees with the costs of removal and the value of post-restoration forage. Through a series of interviews and surveys, coupled with additional data collection and literature review, we found that the benefits of oak restoration through the removal of the Douglas fir encroachment exceeded the costs of treatment for landowners on average.
