Abstract

Mangroves are considered to be the most productive ecosystems in the world. Their contribution in enhancing biodiversity and stabilizing coastal environments is widely accepted. Reintroduction of mangrove vegetation need be prioritized in the context of predicted consequences of global warming, sea level rise, coastal erosion and other natural as well as manmade disturbances. The primary objective of this study is to demarcate environments that uphold adequate water quality ideal for mangrove afforestation along the coastal and inland water bodies of Malappuram district, Kerala. Collection of water samples were carried out from38 locations representing diverse habitats during pre-monsoon, monsoon and post-monsoon seasons. Physico-chemical characterizations of collected samples were carried out following standard methods. On the basis of salinity and related attributes, high salt tolerant species like Avicennia marina, Avicennia officinalis, Rhizhophora mucronataand Aegiceras corniculatum were found to beideal for afforestation in 10 sites. Low salt tolerant species like Sonneratia casiolaris and Exocaria agallocha were noted to be ideal for planting in 8 sites. Species like Sonneratiaalba which showed a tolerance limit over a wider range has beenfound ideal for afforestation in 14 selected sites. However medium salt tolerant species like Rhizhophora apiculata, Bruguiera gymnorrhiza and Bruguiera cylindrica were found to be unfit for afforestation in any of the sites studied. On an overall assessment of the tolerance limit of mangrove species to salinity, 11 inland and estuarine aquatic environments of Malappuram District are ideal for afforestation during all seasons of the year.
