This dataset was used to summarize and analyze the mortality factors recorderd on dead trees in the Sierra Nevada Forest Dynamics Plot Network, which is managed by the Sequoia and Kings Canyon Field station of the U.S. Geological Survey's Western Ecological Research Center. Each row of the dataset represents an individual dead tree. These are dead trees that were recorded in the network from 1998 to 2010 for the subset of plots as described in the associated manuscript; Das, A.J., Stephenson, N.L., Davis, K.P. 2016. Why do trees die? Characterizing the drivers of background tree mortality. Ecology. 97(10): 2616-2627, http://dx.doi.org/10.1002/ecy.1497

Yosemite National Park, California. Glaciated rock between Mono Pass and Parker Pass. The direction of ice motion was from the foreground on the right toward the distance on the left. An angular cavity, due to the plucking of a block separated by joint planes, was modified by subsequent abrasion. The hill beyond is a spur of Mount Gibbs. 1903.

Yosemite National Park, California. Glaciated rocks between Mono Pass and Parker Pass in the Sierra Nevada. The direction of ice motion was from right to left. A joint face on the lee side, exposed by the plucking away of a block, remains unscored. 1903.
thumbnail
Yosemite National Park, California. Merced Lake lies in a Yosemite-like stretch of the upper Merced Canyon. Its basin, hollowed from the granite by the ancient Merced Glacier, is in the process of being filled with river-borne sand and gravel and will, in time, be replaced by a level floor analogous to that of Yosemite Valley. At the head of the lake is the forested delta of the river. Circa 1914. Plate 12-B, U.S. Geological Survey Professional paper 160.
