The Biodiversity of India


Book Description

Over 45,000 plant and 77,000 animal species have been recorded in India and make up 7 per cent of the total plant and 6.4 per cent of the total animal species found in the world. The enormous variation of landscapes due to climate and topography has created different ecosystems that support and nurture this bio-diversity. From the majestic Himalayas in the North to the lush tropics of the South, the precious natural resources of this subcontinent are found in forest, grassland, island, coastal belt, marine, desert and semi-arid ecosystems. Industrialization and modern ways of life are pillaging these resources and posing a monumental threat to the natural world. It is estimated that as many as 50 per cent of the earth's species are likely to become extinct during the first two decades of the 21st century.










Recovering Biodiversity in Indian Forests


Book Description

This book demonstrates how varying levels of human disturbance manifested through different management regimes influence composition, richness, diversity and abundance of key mammal, bird and plant species, even within ecologically similar habitats. Based on our results, we show the critical importance of the ‘wildlife preservation’ approach for effective biodiversity conservation. The study also provides examples of a practical application of rigorous methods of quantitative sampling of different plant and animal taxa as well as human influences, thus serving as a useful manual for protected area managers. Protected areas of various kinds have been established in India with the goal of arresting decline in, and to provide for, recovery of biodiversity and ecosystem services. A model that targets ‘wildlife preservation’ under state ownership is practiced across the country. However, forests in India are under intensive human pressure and varying levels of protection; therefore, protected areas may also experience open-access resource use, a model that is being aggressively advocated as a viable alternative to ‘preservationism’. We have evaluated the conservation efficacy of alternative forest management models by quantifying levels of biodiversity under varied levels of access, resource extraction and degree of state-sponsored protection in the Nagarahole forest landscape of southwestern India.













Bat Roosts in Trees


Book Description

This is a guide to finding tree-roosts. It is the result of the collaborative efforts of professional surveyors and amateur naturalists across Europe as part of the Bat Tree Habitat Key project, and represents a combination of firsts: It is the first time legislation and planning policy have been reviewed and put to practical use to define an analysis framework with clearly identifiable thresholds for action. Yet, despite its efficacy in a professional context, it is also the first time a guide has been produced that is equally effective in achieving its objective for amateurs. It is the first time such a method has been evidence-supported throughout, with summary reviews of each aspect of the roosting ecology of the individual 14 tree-roosting species, with illustrative photographs and data to which the reader has open access. It is the first time a repeatable analysis framework has been defined against which the surveyor may compare their results at every stage, from the desk-study, through ground-truthing, survey and analysis, thereby ensuring nothing is overlooked and that every result can be objectively compared. The survey and analysis framework itself is ground-breaking in that it may readily be adapted for any taxa; from moths, through amphibians, reptiles, birds and all other mammals. Used diligently, these methods will reward disproportionately and imbue the reader with renewed confidence as they quickly progress from beginner to competency. Thus, this book is for everyone who has ever wanted to find a tree-roost, or to safeguard against inadvertently damaging one.




Indian Hotspots


Book Description

This book offers a comprehensive account of India's four biodiversity hotspots: the Himalaya, Indo-Burma, Western Ghats and Sri Lanka and Andaman and Nicobar Islands. With a focus on tropical rainforests, it includes more than 30 chapters covering different vertebrate fauna e.g. fishes, amphibians, reptiles, birds, and mammals, as well as topics such as conservation and management aspects. Written by experts in the field of biodiversity conservation and management, it offers ample new insights into a number of subjects related to the faunal communities of tropical forest ecosystems, providing a valuable resource for conservationists and researchers in the field of flora and fauna diversity.




Plant Diversity in India


Book Description

India has a vast landmass of 328 million hectares, extending from the tropics to the alpine regions, rich wetlands to deserts, islands, long coastline to Western and Eastern Ghats and the high Himalayas. It has equally rich and diverse plant diversity, with over 47,000 species that are already documented. Because of the large population dependence on these plants, expansion of agriculture, urbanization and development efforts, many species are threatened too. Some of the issues concerning plant diversity in India are unique to the country. Taxonomic and floristic studies on all major groups have been carried out but the information is scattered in research papers and regional/local floras, manuals and monographs. This volume intends to bridge this gap. Nine of the thirteen chapters of this volume deals with different plant groups extending from algae to angiosperms and allied groups such as bacteria, fungi, lichens, and myxomycetes. There are chapters dealing with topical issues in global context on biodiversity with special reference to India such as climate change and its impact on biodiversity, crop diversity, and tradomedicalism. Each chapter is written by author(s) specialising on the particular group and having long experience of research in it. Each chapter includes not only distribution and diversity but also major researches, economic uses and conventional human interactions. Lacunae in current knowledge are also pinpointed. The book provides information on ecosystem diversity, flora of special sensitive regions (mangroves, wetland, and coral reefs), and on policies and strategies being adopted for in situ and ex situ conservation.
