This paper deals with the land use land cover change monitoring over the years of 17 duration between 1983 to 2000 using coincidence matrix between the classified details of Landsat MSS and IRS-IC LISS III data of respective years. Maximum Likelihood classification and post classification comparison techniques were performed for evolving coincidence matrix. The ground observations and the empirical evidences quantified under the study reflected that the ischolar_main cause of changes among land use land cover types had been centered on coal mining activities. The overall rate of change was found as 2.16% per year. This includes 0.1% per year change due to coal mines. The agricultural land was reduced by 26.40km2 or 22.35% out of its total area and the land was transformed into coal maines, habitation related to coal mines and the abandoned agricultural land classified as grassland! scrub. Coal mining activities have also caused the loss of tree and bamboo vegetation cover by 54.79 km2 or 7.27% out of the total area indicating the rate of loss as 0.6% per year.- Soil Physico-chemical Characteristics of Bryophytic Vegetation Residing Kedarnath Wildlife Sanctuary (KWLS), Garhwal Himalaya, Uttarakhand, India

The present study was undertaken at eight different sites of Kedarnath Wildlife Sanctuary (KWLS) of Garhwal Himalaya, India to understand the physico-chemical properties of soils and influence of bryophytic communities on the status of nutrient availability. In the bryophytes dominated sites the values of organic carbon (0.21%) and nitrogen (0.04%) were found to be low as compared to values for forest soils dominated by higher plants which suggests that bryophytes prefer to occupy the barren sites with low organic matter. Mean available phosphorus content in soil of various sites varied between 13.02 Kgha-1 and 16.28 Kgha-1 with estimated mean exchangeable potassium content ranged between 145.60 Kgha-1 and 216.16 Kgha-1. A significant negative correlation between soil temperature and moisture content was observed, whereas organic carbon and available phosphorus exhibited significantly positive correlation. Besides the characteristics of soil underneath the bryophytic vegetation, the study also highlights the kind of bryophytes communities found along altitudinal variation and soil types.Keywords
