Sugar Pine

The sugar pine is the largest species of pine, commonly growing to 130–200 ft tall, with a trunk diameter of 5–8 ft. The leaves (needles) are in bundles (fascicles) of five, with a deciduous sheath. They are 2-4 inches long. Sugar pine is notable for having the longest cones of any conifer, mostly 10–20 in. long. The seeds are 0.4-0.5 in. long, with a 0.75-1.2 in. long wing that aids wind dispersal. The seeds of the sugar pine are also a type of pine nut and are edible. The sugar pine has long straight branches, weighed down at the tips by the cones.

Coast Live Oak

Coast live oak typically has a much-branched trunk and reaches a mature height of 10–25 meters (33-82 feet). Some specimens may attain an age exceeding 250 years, with trunk diameters up to three or four meters (10-13 feet), such as those on the Filoli estate in San Mateo County. The trunk, particularly for older individuals, may be highly contorted, massive and gnarled. The crown is broadly rounded and dense, especially when aged 20 to 70 years; in later life the trunk and branches are more well defined and the leaf density lower. The leaves are dark green, oval, often convex in shape, 0.75-2.75 in. long and 0.4-1.6 in. broad; the leaf margin is spiny-toothed (spinose), with sharp thistly fibers that extend from the lateral leaf veins.
