Northwest Gateway Forest Restoration
One hundred years of fire exclusion in the northwest corner of Lassen Volcanic National Park has resulted in overly dense and unhealthy forest areas. In the absence of surface fires, young white fir have formed dense thickets crowding out old growth pines, aspen stands, and understory shrub and grass vegetation. Lassen Volcanic will implement a mechanical treatment strategy to remove unhealthy fuel loads. The process will reduce old growth mortality rates, promote a more varied stand structure, and restore and protect wildlife habitat.
