First census of Yosemite 25-ha plot completed

On Friday July 9, 2010, CTFS-SIGEO partners finished the first census of the 25-ha plot located in Yosemite National Park. Seven temperate plots, at varying stages of enumeration, are now in place in North America.

Field work started last year during the last two weeks of June, when more than 13,000 individual trees in approximately 10 ha were censused. The census of the second half of the plot required about the same number of fieldwork hours as the first.

The Yosemite Forest Dynamics Plot is located near Crane Flat in Yosemite National Park, with white fir (Abies concolor), sugar pine (Pinus lambertiana), and Pacific dogwood (Cornus nuttallii) making up most of the species. The principal investigators are Drs. James Lutz and Andrew Larson.
