This "small grove of exotic trees" was probably planted in the 1910s by LA Times publisher Harrison Gray Otis on what was then "his large estate" in Tarzana. The estate is now gone, but the trees remain.

The 150-foot-tall, sandstone Eagle Rock "is considered to be one of the most distinctive natural landmarks in the city of Los Angeles ... It has remained a consistent visual landmark throughout Eagle Rock's prehistory, its incorporation as a city in 1911, and its consolidation to the city of Los Angeles in 1923."

Dating from 1920, this tree used to shade the Koyosan Buddhist Temple; the temple was demolished but "the tree has remained untouched and has strong associations with the cultural and historical development of Buddhism and the Japanese American community in Los Angeles."

These mature Mexican Fan Palms running from San Fernando Road to Avenue 32 are an "[e]xcellent intact example of subdivision improvements during the early part of the 20th century."

The six-acre Toluca Lake is an "excellent and rare example of a natural lake ... historically fed by underground springs." When the surrounding land was subdivided for a fancy neighborhood in 1923, "a series of community wells were installed along the lake's edge to maintain the water level."

This Moreton Bay Fig dating to 1920 is rare for its age and size.

This Live oak dating to 1920 sits on an island on Bromont Avenue and "predates the development surrounding it."

These Mexican Fan Palms running between San Fernando Road and Avenue 32 are "an [e]xcellent intact example of subdivision improvements during the early part of the 20th century."

This 1910 tree is an "[e]xcellent mature example of a Morton Bay Fig in a dense urban area that is generally lacking in street trees."

These "mature street trees," running between Ventura and Valley Vista, are "associated with the subdivision of the tract for residential development in the late 1930s." They're mostly Jacaranda, with some Pines and Cedars thrown in.

The 218 Mexican fan palms lining Avalon from East Lomita Boulevard to First Street in Wilmington "were planted in 1931 by the City of Los Angeles as part of beautification efforts for the 1932 Olympic Games."

These figs were planted in 1913 by landscape architect Wilbur Cook "on land sold to developer William Mead by Colonel Griffith J. Griffith, who donated Griffith Park to the City of Los Angeles."

Located in the Florence-Firestone neighborhood, the Mexican Fan palm trees that line Avalon Blvd between Florence and Manchester are considered an "excellent intact example of streetscape improvements from the period."

The mature palm trees on both sides of Ventura Boulevard run for a mile between Carpenter Avenue and Whitsett Avenue (Studio City's "primary linear commercial district). They were planted back in 1959 by the Studio City Beautiful Committee; the first trees went in at Ventura and Laurel Canyon boulevards. The project was part of a broader effort to spruce up the Valley's commercial areas that extended into the 1960s.

These Washingtonia robusta palm trees likely date back to 1908, "the time of subdivision of the residential tract in which they are located." They line 55th and 56th streets between Normandie and Denker.

This grove planted at the Santa Monica Forestry Station (the nation's first experimental forestry station) was studied by scientists and was later partly responsible for the introduction of the eucalyptus tree into SoCal. The original eucalyptus were planted sometime between 1888 and 1920, while the station was in service.
