The Four Forest Restoration Initiative was created to accelerate an ambitious restoration program to improve and sustain watershed health, improve wildlife habitat, conserve biodiversity, protect old-growth, reduce the risk of uncharacteristic wildland fire and promote the reintroduction of natural fire, and restore natural forest structure and function so that forests are more resilient to climate change. The initiative spans 2.4-million-acres on the Apache-Sitgreaves, Coconino, Kaibab and Tonto national forests
