Coast live oak, scientifically known as Quercus agrifolia, is a species of oak tree that is native to the coastal areas of California and Baja California in Mexico. It belongs to the Fagaceae family and is a prominent, long-lived evergreen tree that can reach heights of up to 20-80 feet (6-24 meters) with a spread of 20-100 feet (6-30 meters). The tree has a distinctive rounded canopy and a wide trunk with thick, rough, and dark grayish-brown bark.
The leaves of the coast live oak are leathery and oval-shaped, with wavy margins and a glossy dark green color. They are typically 2-4 inches (5-10 centimeters) long and have a holly-like appearance due to the spiny lobes. The tree produces small acorns, around 0.5-1.5 inches (1-4 centimeters) in length, which are an important food source for various wildlife such as squirrels, jays, and deer.
Coast live oaks are considered an essential component of the California coastal ecosystems, playing a vital ecological role in providing habitat and food for numerous species, aiding in soil stabilization, and helping to control erosion along the coast. They are often found in woodlands, canyons, and open spaces, and are known for their resilience and adaptability to various soil conditions.
Due to their aesthetic value, as well as the shade and coverage they provide, coast live oaks are also commonly found in landscaping and urban settings, including parks, gardens, and streetscapes. Their durability, low maintenance requirements, and ability to withstand drought make them a popular choice for a variety of landscapes in the region.
