Oak savanna definition

Oak savanna means an Oak Habitat with a community of widely spaced Oregon white oak trees (Quercus garryana) where total canopy coverage is less than twenty-five percent (25%) but where Oregon white oak accounts for at least fifty percent (50%) of the canopy coverage above a layer of native prairie grasses and forbs. The spacing of these trees is widely scattered so that there is no closed canopy and groups of trees. In degraded habitat, trees may be more widely spaced above a layer of non-native vegetation on developed property.
