Quercus agrifolia

Quercus agrifolia, commonly known as the California live oak, is a species of oak tree native to the California Floristic Province. It is classified in the red oak section (Quercus sect. Lobatae).

Description

Quercus agrifolia is an evergreen tree that can reach a height of 20–25 meters. The leaves are dark green, oval, often convex in shape, and have toothed margins. The acorns are 2–3 cm long, round, and mature in about 6–8 months after the flowering in spring.

Distribution and habitat

The California live oak is endemic to California, where it is found in areas with a Mediterranean climate. It is commonly found in the coastal fog belt, but also grows in inland valleys and mountains up to an elevation of about 5000 feet.

Ecology

Quercus agrifolia plays a crucial role in the ecosystems where it is found. It provides food and habitat for a variety of wildlife species, including birds, mammals, and insects. The acorns are a particularly important food source for many animals.

Uses

The wood of the California live oak is hard and durable, making it valuable for construction and furniture making. The acorns were also a significant food source for Native American tribes in California.

Conservation

While not currently listed as threatened or endangered, Quercus agrifolia is facing several threats, including habitat loss due to urban development and the spread of sudden oak death, a disease caused by the pathogen Phytophthora ramorum.
