Oak Savannas & Woodlands
Oak savanna and woodland habitats are native to the Willamette Valley, provide an important, unique habitat for many species, and are culturally significant to local Native American tribes. However, they have become increasingly rare over the last 150+ years. Many areas that were historically oak savanna and woodland habitats have been turned into urban or agricultural areas. Where oak habitat still exists, oftentimes Douglas fir have moved in and shaded out the sun-loving oaks, making it hard for them to thrive. In the past, Native American tribes used fire to keep oak savannas and woodlands open, but that practice is largely gone today. Therefore, in our oak project areas, we thin out the Douglas fir to provide space for oak canopies to flourish. We also remove weeds and plant native grasses and wildflowers.
