Eddy Arboretum : ウィキペディア英語版 | Eddy Arboretum
The Eddy Arboretum is located at the Institute of Forest Genetics in the Sierra Nevada near Placerville, in El Dorado County, eastern California. ==Collection== The arboretum contains what is claimed to be the best-documented collection of native and exotic pines in the world, in addition to many other native and exotic conifers. 78 pine species, 24 fir species, and many other conifer species are growing on the arboretum's grounds. Some species collections sample a wide range of genetic diversity, such as the native California conifers ''Pinus lambertiana'' and ''Pinus coulterii''. The Arboretum's first plantings were made in 1926. Because genetic diversity is the raw material for breeding, the Arboretum assembled as many pine species and varieties as possible. The origins of individual seeds were recorded, often mapping the location of each parent tree.
