Description of site: The Ratnagiri Mangroves region
comprises the three estuaries Bhatye, Kalbadevi, and Are, located near the
city of Ratnagiri. Anthropogenic pressures are heavy at the mouth of Bhatye
estuary/ Kajvi river (forming the southern boundary of Ratnagiri city) while
the upstream areas are relatively less disturbed. Human activity is also intense
at the mouth of Kalbadevi estuary from where a large channel of water descends
southward, forming the Shirgaon creek, which supports a large number of mangrove
species. Are, the smallest of the three estuaries, is relatively less inhabited
and supports more extensive vegetative cover than the other two. Daily tides
flood the vegetation, affecting soil salinity
Climatic conditions: Tropical monsoon climate. Average
annual rainfall is 2000 mm. Temperatures vary from 12.5° C to 36° C
Principal vegetation: Woody mangroves cover the
area. The dominant species are Rhizophora mucronata, R.apiculata, Sonneratia
albs, Avicennia officinalis, A. marina, Ceriops tagal, Aegiceras corniculatum.
