The Blue Oak, scientifically known as Quercus douglasii, is a deciduous tree native to California. It typically grows in dry, hilly areas and can reach heights of 30 to 60 feet. The tree is characterized by its blue-green leaves, which are lobed and can be up to 4 inches long. Blue Oaks are well-adapted to drought conditions and can live for over 200 years. This species plays a vital role in its ecosystem, providing habitat and food for various wildlife, including birds and mammals. The acorns produced by Blue Oaks are an important food source for animals such as squirrels and deer. Their presence contributes to the biodiversity of the regions they inhabit.
