    Abstract: This paper presents a time series study of an alpine ecosystem in the Big Pine Creek watershed in California’s Eastern Sierra Nevada Mountain’s. Seventy five sample sites along a 2,500 meter elevation gradient are analyzed for trends in surface reflectance based on vegetative density using USGS data derived from Landsat imagery for the 1984 through...
