Mangroves Of India

This is the first comprehensive science-based primer to highlight the unique ecosystem services provided by mangrove forests, and discuss how these services preserve the livelihoods of coastal populations. The book presents three decades of real-time data on Sundarbans and Bhitarkanika mangroves in India measuring carbon and nitrogen sequestration, as well as case studies that demonstrate the utility provided by mangroves for reducing the impact of storms and erosion, providing nutrient retention for complex habitats, and housing a vast reservoir of plant, animal and microbial biodiversity. Also addressed is the function of mangroves as natural ecosystems of cultural convergence, offering the resources and products necessary for thriving coastal communities. The book will be of interest to students, academics and researchers in the fields of oceanography, marine biology, botany, climate science, ecology and environmental geography, as well as consultants and policy makers working in coastal zone management and coastal biodiversity conservation.

Manual of Indian Mangroves The fully illustrated colour book deals with the present status of the mangrove ecosystem of Indian territories in general and the mangrove ecosystem along with the mangroves and mangrove associated plants and mangrove inhabiting faunal assemblages of the Indian Sundarbans, in particular. Mangroves, the unique ecosystem is in very much stressed or threatened condition throughout the globe in general and in Indian territories, as well. Over all distribution of these mangrove plants in the Indian territories and abroad and their present status within India are dealt vividly by short description with key characters of these available Indian mangroves and mangrove associated plants along with its photographs, mentioning of habits and habitat condition, correct identifying key characters, nomenclature, taxonomic status, local and common names, etc. Besides these, the mention of the world distribution of mangroves and the world mangrove species along with their ideal habitat conditions are also dealt. Necessary photographs and description of their diverse aerial root system, canopy structure, flowers, fruits, viviparous germinated hypocotyles and interesting seedling developmental stages are also highlighted; as such, it is the most important handbook and as the field guide book for identifying each and every individual Indian mangrove plant species, along with their status. The overall conservation strategies of these mangroves, need for coastal zone stabilisation or protection of coastal areas by conserving these mangrove ecosystem and the need for maintaining the coastal fisheries potentialities with the mangroves are also dealt critically with the mention of sustainable utilization and relationship of these coastal and estuarine fisheries and mangrove ecosystem, as well.

Mangroves are basically salt tolerant forest ecosystems found mainly in tropical and sub-tropical inter-tidal regions. Till about 1960s, mangroves were largely viewed as “economically unproductive areas” and were therefore destroyed for reclaiming land for various economic and commercial activities. Gradually, with the passage of time, the economic and ecological benefits of mangroves have become visible and their importance is now well appreciated. Today, mangroves are observed in about 30 countries in tropical subtropical regions covering an area of about 99,300 Sq.Km. However, during the past 50 years, over 50% of the mangrove cover has been lost, mainly because of the increased pressure of human activities like shrimp farming and agriculture, forestry, salt extraction, urban development, tourist development and infrastructure. Also, dam on rivers, contamination of sea waters caused by heavy metals, oil spills, pesticides and other products etc. have been found to be responsible for the decline of mangroves. Although the temperature effect on growth and species diversity is not known, sea-level rise may pose a serious threat to these ecosystems The present book addresses all these important issues in separate chapters with some interesting case studies whose data may serve as pathfinder for future researches in the sphere of the influence of climate change on mangrove ecosystem. The role of mangroves in the sector of bioremediation is a unique feather in the crown of this coastal and brackishwater vegetation that may be taken up by the coastal industries in order to maintain the health of ambient environment. This book seeks to discover and to assess the vulnerability of climate change on mangrove flora and fauna, their role in carbon sequestration and some interesting case studies by some groups of dedicated researchers that may serve as the basis of future climate related policies.

Mangrove Ecosystem: An Overview Mangroves: Definition and Types ‘Mangrove’ has been variously defined in literature. The Oxford dictionary mentioned the words ‘mangrove’ since 1613, indicating tropical trees or shrubs found in coastal swamps with tangled roots that grow above the ground. Later, the term ‘mangrove’ was referred to the individual plant or tidal forest or both, as ‘Mangrove plants’ and ‘Mangrove ecosystem’ (MacNae 1968). Chapman (1984) used the term ‘mangrove’ for inter tidal plants, and considered plant communities of inter tidal forest as mangrove ecosystem called ‘mangal’. The term ‘mangal’ was also commonly used in French and in Portuguese to refer to both forest communities and to individual plants. Several workers have opined that plants growing in between the highest and the lowest tidal limits may be considered ‘mangrove’ (Aubreville, 1964; MacNae, 1968; Blasco, 1977; Tomlinson, 1986; Naskar & Guha Bakshi, 1987). The tidal limits of various habitats, however, can vary. Mangrove plants comprise a heterogeneous group of independently derived lineages that are defined ecologically by their occurrence in tidal zones along shorelines and in estuaries and physiologically by their ability to withstand high salt concentrations and low soil aeration. Based on their abundance, distribution, and habitat specificity, Tomlinson (1986) distinguished major and minor mangrove elements as well as mangrove associates. He recommended that mangrove species were basically of two types, viz., (1) Major element of mangals or true mangroves – with complete fidelity to the mangrove environment, and (2) Minor element of mangals – not conspicuous in mangrove habitats, rather might prefer the peripheral habitats of mangrove regions. The term ‘Mangrove associate’ was coined for the flora representing nonarborescent, herbaceous, sub-woody and climber species, found growing mostly in regions bordering the tidal periphery of mangrove habitats. Tomlinson (1986) used fairly rigid criteria to distinguish true mangroves from mangrove associates. In his criteria, true mangroves possess all or most of the following features: (i) occurring only in mangrove environment and not extending into terrestrial communities; (ii) morphological specialization (aerial roots, vivipary); (iii) physiological mechanism for salt exclusion and/or salt excretion; (iv) taxonomic isolation from terrestrial relatives.
