“…The significant relationship between MCH and TAGB that is evident in the results of our analysis of data from the aerial photographs suggests that it might be possible to scale up this technique to permit the use of satellite remote sensing data. That is, if local variations in TAGB could be detected from satellite images that provide structural information on the vegetation surface, it would become possible to reduce the dependence on large-scale aerial photography and on labor-intensive measurements of the DBH and height of individual trees (Botkin et al, 1984).…”

“…Satellite remote sensing has played a key role in generating information about forest cover, vegetation type and land use changes (Houghton and Woodwell 1981;Botkin et al 1984;Malingreau 1991;Roy 1993). Multitemporal satellite data have been used to quantify tropical deforestation and habitat fragmentation in the spatial context (Skole and Tucker 1993).…”

The process of forest fragmentation, a common phenomenon occurring in tropical forests, not only results into continuously forest getting fragmented but also brings about several physical and biological changes in the environment of forests. Consequently, there is a loss of biodiversity due to change in habitat conditions. These remnant fragments provide the last hope for biodiversity conservation. The present study deals with the impact of decreasing patch size of a fragmented forest on the diversity of the tropical dry deciduous forests in Vindhyan highlands, India. There is considerable change in the vegetation cover of this region owing to rapid industrialization and urbanization, which has also contributed to forest fragmentation. In the present study, remotely sensed data has been used to describe the changes brought about in vegetated areas over a period of 10 years as a result of fragmentation and its impact on biodiversity was assessed. Further, in order to assess the loss of species with respect to the reduction in patch size, species area curves for various change areas were analysed. It was observed that the rate of decrease in the number of species is faster in the case of negative change areas as compared to the positive change areas of the region. Various diversity indices also support this observation. Such an analysis would help in formulating appropriate conservation measures for the region.

Abstract:In order to estimate changes in carbon pools and fluxes to the atmosphere, we used LANDSAT/TM data to calculate the extent of areas converted to pasture to different lengths of time in a 100 x 92 km area of the southwestern Brazilian Amazon. Image processing and the supervised classification allowed the production of an accurate land cover map including forest and pastures of different ages. The results showed that almost 30% of the natural forest were deforested and occupied with pasture. From the 2800 km 2 of pasture almost 60% consists of pasture with less than three years of establishment. Estimates of carbon pools and fluxes to the atmosphere were carried out using the results of LANDSAT image analysis and published data about carbon stocks in vegetation and soil. The results showed that a large amount of carbon ( 12x10 3 g C m -2 ) is released after three years under pasture. From the initial burning and after fifth year under pasture, the system functioned as a source of CO 2 to atmosphere. After this period the balance is slightly negative and the amount of CO 2 released is lower than the amount released in the initial period.
