9. II. Mammoth Mountain Location: Inyo National Forest, CA, USA Coordinates: 37°37′50.26″N , 119°1′57.45″W Elevation: 11,059 ft (3,371 m)

11. - In early 1990’s, there was the first notice of dead and dying trees on the south side of Mammoth Mountain - In1994, USGS surveyed for carbon dioxide gas around Mammoth mountain , and exceptionally high concentrations of gas were found in the soil beneath the trees Source: USGS(2004) Source: USGS(2004)

16. IV. Result

27. According to USGS (2000), the spectrometer field results show that carbon-isotopic analyses of the annual growth rings in trees near the margins of the tree-kill areas imply that the gas-emission rate reached a peak in 1991, subsequently declined, and then have been relatively stable since about 1996 Spectrometer field results (USGS, 2000)

28. The SVM classification result shows the area of dead/dying tree was in similar location to the USGS result. However, the comparison of total coverage of classification result may not always provide the most efficient analysis of changes due to the difference in vegetation spectral
