Encroachment
Frequent, low-intensity fires help shape and maintain the health and diversity of oak ecosystems. Fire suppression has removed this natural disturbance process, allowing conifers, woody shrubs, and younger oaks to become established. As a result, oak stands are becoming extremely dense, creating stress on larger oak trees and degrading overall woodland health. This has led to a reduction in habitat quality, the build-up of fuel loads, and an increased risk of uncharacteristically severe wildfire.
