last decade in Pranahita Wildlife Sanctuary, Adilabad district, Andhra
Pradesh, India using Landsat TM and IRS P6 LISS III images. From 1993
to 2004, the forest cover had a severe change and lost about 248.87 ha.
There was increase in the scrub cover to about 1637.17 ha, which was quantified
to be 172.77 ha. Over all change analysis from 1993 to 2004 with reference
to forest cover indicates, negative changes (loss of forest area) accounted
for 1229.02 ha (9.04%) area and positive changes (gain of forest) for
an area of 980.14 ha (9.04%). The results of the change detection using
multi-date satellite imagery suggest that the most of the forest cover
has been clearly degrading over the years. The study concluded that underlying
causes for the forest cover change are multifarious including illegal
logging, grazing, forest fire, expansion of agricultural lands and invasion
of exotic species.]]>Champion, H.G. and S.K. Seth,19681st Edn.,Pages: 404Pages: 404Cihlar, J., 20002110931114Congalton, R.G., 19941994pp: 383388Giri, C.P., R.S. Ofren, D. Pradhan, E.
