Umatilla National Forest

In 2023, Umatilla National Forest undertook a significant reforestation initiative to rehabilitate areas affected by the 2021 Elbow Creek, Green Ridge, and Lick Creek fires. These wildfires collectively burned approximately 150,000 acres across northeastern Oregon and southeastern Washington, leaving substantial portions of the forest in need of ecological restoration. The 2023 project focused on reestablishing native tree species to restore forest structure, enhance wildlife habitats, and improve watershed health.

The reforestation effort involved planting 350,000 seedlings across approximately 2,300 acres of the most severely impacted areas. The selection of tree species was tailored to the specific ecological requirements of the sites and included western larch, Douglas fir, ponderosa pine, and western white pine. These species were chosen for their adaptability to local conditions and their roles in promoting biodiversity and ecosystem resilience.

Prior to planting, comprehensive site assessments were conducted to determine soil conditions, moisture levels, and appropriate planting densities. These evaluations ensured that the seedlings were placed in environments conducive to their growth and survival. The planting process was meticulously planned to optimize spacing and site selection, thereby enhancing the establishment and long-term health of the new forest stands.

This 2023 initiative built upon previous restoration efforts within Umatilla National Forest. In the aftermath of the 2021 fires, initial recovery actions included hazard tree removal, erosion control measures, and the preparation of burned areas for future planting. These foundational steps were crucial in setting the stage for the large-scale reforestation activities that followed.

The success of the 2023 reforestation project is anticipated to yield multiple ecological benefits. Reestablishing native tree cover will aid in stabilizing soils, reducing erosion, and improving water quality in the forest's watersheds. Additionally, the restored forest stands are expected to provide critical habitats for various wildlife species, including elk, deer, and numerous bird species, thereby contributing to the overall biodiversity of the region.
