Large Trees Declining in Yosemite

A new study by scientists with the U.S. Geological Survey finds that the number of large-diameter trees growing in Yosemite National Park has declined 24% between the 1930s and 1990s.  Although the study did not focus on the reason for this decline, USGS scientists stated that the most likely reason is climate change.  The decrease in large trees is troubling for several reasons:  large trees serve as habitats for many other species, they are the seed source for new trees, and can often better withstand fires, insect outbreaks and other negative environmental effects.  For more information on this study, see ScienceDaily.
