The Yosemite Forest Dynamics Plot is located near Crane Flat in Yosemite National Park. It lies in old-growth sugar pine and white fir forest. The plot is 25.6 ha (800 m x 320 m) with all woody stems (trees and shrubs) mapped at dbh (1.37 m). Canopy trees are generally 100 cm to 200 cm dbh. The largest living tree is 204.1 cm dbh Pinus lambertiana, but there is a P. lambertiana snag that is 229.1 cm dbh.
Forest composition is principally white fir (Abies concolor), sugar pine (Pinus lambertiana), incense cedar (Calocedrus decurrens), ponderosa pine (Pinus ponderosa), and California black oak (Quercus kelloggii). Animal species include American black bear (Ursus americanus), cougar (Puma concolor), coyote (Canis latrans), mule deer (Odocoileus hemionus), and a rich assortment of rodents, including deer mouse (Peromyscus maniculatus), brush mouse (Peromyscus boylii), chipmunk (Neotamias spp.), and California ground squirrel (Spermophilus beecheyi).
The plot lies within the Rockefeller Grant of 1930. J. D. Rockefeller Jr. purchased the land from the Sugar Pine Lumber Company and gifted it to the park in order to save it from logging. For more information, please click here.
