Bryophytes are of great importance in their ecosystems and for human well-being. They stabilize soil crust through colonization of bare grounds and rocks; they are essential in nutrient recycling, biomass production, and carbon fixing; they control water through an effective retention mechanism; and they have economic value as peat for fuel, horticulture, oil absorption, and as sources of a wide variety of chemical compounds. Bryophytes have long been used for medicinal purposes and provide a food source for reindeer, geese, ducks, sheep, musk-ox, lemmings, and other rodents. Threats include deforestation, cultivation of forests, reclamation of land, urbanization, roads, dam-building, mining, drainage of wetlands and over-grazing. This plan reviews the situation worldwide and proposes a variety of initiatives. It is aimed at those who work with and care about nature conservation, including governmental and non-governmental organizations as well as politicians and the general interested public.
Let the experts at the Royal Botanic Gardens guide you around the beautiful and mysterious world that is the plant kingdom. From regulating the air we breathe to providing food, clothes, fuels, and medicines - plants are fundamental to our lives. Discover an extraordinary diversity of species, which includes a grass that grows a meter a day, roots that breathe air, and "queen of the night" cactuses whose rare blooms vanish before dawn. In a combination of art and science, Flora celebrates plants from majestic trees to microscopic algae, explaining how they germinate, grow, and reproduce. It presents species that have evolved to accommodate pollinating insects such as the foxglove, and plants that have adapted to flourish in even the most hostile of habitats. Pierre-Joseph Redoute in the 18th-century was described as the "Raphael of flowers". Flora showcases his botanical paintings as well as those of Georg Ehret and others in this gorgeous visual celebration of plants through the ages. Whether you are a keen gardener, naturalist, or botany student, this beautiful book is a treat that will entice, inform, and amaze.
Located in the heart of the Eastern Himalayas, Bhutan practices the philosophy of Gross National Happiness (“GNH”) that embraces environmental conservation as one of the main building blocks for its sustainable development goals. Bhutan’s conservation strategies and success are largely driven by the strong political will and visionary leadership of His Majesty the King of Bhutan The nation’s Buddhist perspectives regarding a deep and abiding respect for nature; and the strategic enforcement of a wide-ranging stringent set of internal regulations and controls have helped ensure ecological gold standards in Bhutan. Moreover, the country is an active member of the international conservation community by fulfilling its implementation of various Multilateral Environment Agreements. While it emerged into the 21st century as one of the 36 global terrestrial “hotspots” in biological diversity conservation ranks, Bhutan’s sheer commitment with more than 51% of its territory being managed under the explicit status of a protected area network, and more than 70% of the land under forest cover, represents Bhutan’s exemplary dedication to protect the planet despite its smallness in size and economy, and the biological fragility exemplified by its hotspot situation. In the face of imminent severe threats of global warming, Bhutan nonetheless exemplifies the truth that “a small country with a big conservation commitment” can make an enormous contribution to the global community. At the regional level, Bhutan is intent upon protecting the Water Towers of Asia (that glacial expanse of the Himalayas) which is a critical resource bulwark for about one-fifth of the global population downstream in South Asia. Such protections invariably help mitigate climate change by acting as a nation-wide carbon sink through its carbon neutral policies. In short, Bhutan has long represented one of the world’s foremost national guardians of biodiversity conservation, ecological good governance, and societal sustainability at a period when the world has entered the Anthropocene – an epoch of mass extinctions. We envision this publication to be ecologically and ethically provocative and revealing for the concerned scientific communities, and governments. Through an extensive review of the scientific and anthropological literature, as well as the research team's own data, the Author's have set forth timely recommendations for conservation policies, strategies and actions. This book provides technical and deeply considered assessments of the state of Bhutan’s environment, its multiple, human-induced stressors and pressures; as well as extremely sound, practical techniques that would address conservation strategies in the Himalayas and, by implication, worldwide.
