Stanford University Arboretum
The arboretum began with the indigenous live oaks on Leland Stanford's estate, which later became the university campus, augmented by a variety of trees that he collected. In 1885 Stanford contracted with noted landscape designer Frederick Law Olmsted to plan the grounds. An 1888 memorandum by Olmsted, and signed by Stanford, states that the then-extant University Forest and the Arboretum were to be combined, and that "In this enlarged Arboretum it is desired that there shall be exhibited to advantage all the trees and wood plants of the world that may be expected to grow to mature natural forms under the climatic and other conditions of the locality." As Jane Stanford said in her 1903 address to the Stanford trustees:
- No buildings of any kind whatever should ever be erected within the grounds of the original Arboretum. It should always be retained in its present condition as a Park for drives and walks so long as the University exists. This Park was a favorite project of my husband and carried into effect twenty-eight years ago. There are many miles of drive[s] within, or connected with shaded avenues, with this beautiful park. The choicest trees are there planted from all parts of the world, and as the years roll on and this most beautiful valley of Santa Clara becomes, as I have no doubt it will, the educational center of our State and thickly settled with beautiful homes, this park will be unique and of itself memorable and monumental. It should, accordingly, always be sacredly preserved from mutilation.
No tree collection
However, these plans for a major tree collection within the arboretum grounds did not materialize. A report by the Olmsted Brothers (May 8, 1914) states: "The so-called 'Arboretum' extends on either side of the main approach from the County Road. At present the name Arboretum is a misnomer as the name implies that a great variety of trees in botanical order are to be found there. It consists, as a matter of fact, mostly of a thick plantation of Blue Gums and Monterey Cypress." Subsequently the Department of Botany was given supervisory control of the arboretum in order to utilize it more fully for scientific purposes. During the twentieth century the arboretum was sometimes under development, but seldom given great attention.
At present the arboretum contains over 350 species representing 150 genera and sixty families. The most common tree is the coast live oak, although valley, blue, and black oaks[disambiguation needed] are also represented. For some years the arboretum was neglected, though in recent years there has been greater interest in its care. There has been some loss of diversity from the original tree and shrub plantings of the 1880s and 1890s, which is well documented for conifers. Although the eucalyptus collection is still prominent, over the past quarter century there has been a significant loss of Eucalypt species, from over 100 to 51 today. Some of the older tree specimens in the arboretum are an Atlas Cedar, California Washingtonia, California sycamore, Canary Island Date Palm, coast live oak, Deodar Cedar, Hampton oak, red mulberry, Santa Lucia Fir, Torrey Pine, and White Ash.
