Abstract

A study was conducted during January 2017 on the biomass of dominant mangrove species in Satjelia Island, located in the central Indian Sundarbans. Eight species of true mangroves were documented in the selected plots. The mean order of abundance of these species was Avicennia alba (23.33%) > Avicennia marina (20.00%) > Excoecaria agallocha (16.66%) > Sonneratia apetala (13.33%) = Avicennia officinalis (13.33%)> Acanthus ilicifolius (6.66%) > Aegiceros corniculatum (3.33%) = Bruguiera gymnorrhiza (3.33%). The above ground stem biomass of the dominant mangrove trees were 19.79 t ha-1, 5.83 t ha-1, 20.22 t ha-1, 21.14 t ha-1, and 6.70 t ha-1 for Sonneratia apetala, Excoecaria agallocha, Avicennia alba, Avicennia marina and Avicennia officinalis respectively.

Abstract

Mangroves provide a wide spectrum of ecosystem services which include improvement of air quality, stabilizing temperature, reduction of ultraviolet radiation, oxygen generation, carbon sequestration, habitat of several flora and fauna (enhancement of biodiversity), aesthetic beauty etc. Oxygen production is one of the most common but under-researched benefits of mangroves. The primary aim of this article is to estimate the oxygen production potential of dominant mangrove species in Indian Sundarbans.
