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. Raw Landsat
data covering the years 1984 through 2011 is converted to observed surface
reflectance and analysed for trends. Analysis of environmental data indicates a
definite warming trend while observed surface reflectance shows a general
decline for the study area over this time period. While declining reflectance in
the visible bands suggests an increase in surface vegetative cover, the fact that
the IR band also shows declines suggests a potential change in vegetative
composition towards species with less structural complexity. This study provides
a useful insight into the ecological response of the Big Pine Creek watershed.
Keywords: Landsat, remote sensing, alpine watershed, climate change, time
