ABSTRACT
Mangrove community has essential benefits to human-beings and other living creatures since it has physical, biological, social and economic functions. Now-a-days, the mangrove area tends to decrease due to land
conversion by anthropogenic activities. The purpose of this study was to evaluate the extent of mangrove land on the north coast of Central Java, based on the geospatial analysis approach using Landsat 8 satellite imagery. The results of the measurement of the mangroves community area on the north shore of Central Java in 2014 showed an increase of 2,922.76 ha or 118.89% for three years. A significant increase was due to the absence of detection of mangrove areas in embankment ponds by previous studies. Also, it was due to increasing mangrove vegetation rehabilitation activities on the north coast of Central Java, as
well as the natural mangrove development of secondary succession over three years (from 2011-14). The field survey encountered 22 mangrove species growing on the north coast of Central Java, where Avicennia
marina and Rhizophora mucronata dominated all research sites. Based on the rejuvenation category, the mangrove sapling category dominated Brebes Regency, Kendal Regency having the highest density of seedling mangrove, and the tree mangrove category met plentiful in Rembang Regency.
