Key Biodiversity Area
The Key Biodiversity Areas (KBA) approach helps to identify and designate areas of international importance in terms of biodiversity conservation using globally standardised criteria. KBAs extend the Important Bird Area (IBA) concept to other taxonomic groups and are now being identified in many parts of the world, by a range of organisations. Examples include Important Plant Areas (IPAs), Ecologically and Biologically Significant Areas (EBSAs) in the High Seas, Alliance for Zero Extinction (AZE) sites, Prime Butterfly Areas, Important Mammal Areas and Important Sites for Freshwater Biodiversity, with prototype criteria developed for freshwater molluscs and fish and for marine systems. The determination of KBAs often brings sites onto the conservation agenda that hadn't previously been identified as needing protection due to the nature of the two non-exclusive criteria used to determine them; vulnerability; and irreplaceability. The KBA global standard was published in 2016. Obje ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biodiversity
Biodiversity or biological diversity is the variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic (''genetic variability''), species (''species diversity''), and ecosystem (''ecosystem diversity'') level. Biodiversity is not distributed evenly on Earth; it is usually greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Tropical forest ecosystems cover less than 10% of earth's surface and contain about 90% of the world's species. Marine biodiversity is usually higher along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, but will be likely to slow in the future as a primary result of deforestation. It encompasses the evolutionary, ecological, and cultural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecoregions
An ecoregion (ecological region) or ecozone (ecological zone) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregions reflect the best compromise for as many taxa as possible. Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Site Based Conservation
Site-based conservation is an approach to nature conservation that relies on the designation of important or representative examples of sites supporting key habitats or species, such as Key Biodiversity Areas (KBAs) or Important Bird Areas (IBAs). Whilst a rational way of ensuring that the very best resources are protected, it is open to a number of criticisms: * It tends to focus resources and protection on only the best sites. * With a changing climate, the best sites now may not be the best ones to protect for the future. * Wildlife is ignorant of lines drawn on maps by humans. On balance, site-based conservation is an essential part of nature conservation, along with initiatives such as environmental subsidies and planning controls that protect biodiversity across the whole landscape (the broad and shallow approach), and the more holistic ideas of landscape-scale conservation Landscape-scale conservation is a holistic approach to landscape management, aiming to reconcile the ...

Biosphere Reserves
Man and the Biosphere Programme (MAB) is an intergovernmental scientific program, launched in 1971 by UNESCO, that aims to establish a scientific basis for the improvement of relationships between people and their environments. MAB's work engages fully with the international development agenda—specially with the Sustainable Development Goals and the Post 2015 Development Agenda—and addresses challenges linked to scientific, environmental, societal and development issues in diverse ecosystems; from mountain regions to marine, coastal and island areas; from tropical forests to dry lands and urban areas. MAB combines the natural and social sciences, economics and education to improve human livelihoods and the equitable sharing of benefits, and to safeguard natural and managed ecosystems, thus promoting innovative approaches to economic development that are socially and culturally appropriate, and environmentally sustainable. The MAB program provides a unique platform for co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biodiversity Hotspots
A biodiversity hotspot is a biogeographic region with significant levels of biodiversity that is threatened by human habitation. Norman Myers wrote about the concept in two articles in ''The Environmentalist'' in 1988 and 1990, after which the concept was revised following thorough analysis by Myers and others into “Hotspots: Earth’s Biologically Richest and Most Endangered Terrestrial Ecoregions” and a paper published in the journal ''Nature'', both in 2000. To qualify as a biodiversity hotspot on Myers' 2000 edition of the hotspot map, a region must meet two strict criteria: it must contain at least 1,500 species of vascular plants (more than 0.5% of the world's total) as endemics, and it has to have lost at least 70% of its primary vegetation. Globally, 36 zones qualify under this definition. These sites support nearly 60% of the world's plant, bird, mammal, reptile, and amphibian species, with a high share of those species as endemics. Some of these hotspots support up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-Biodiversity Wilderness Areas
A High-Biodiversity Wilderness Area (HBWA) is an elaboration on the IUCN Protected Area classification of a Wilderness Area (Category Ib), which outlines five vast wilderness areas of particularly dense and important levels of biodiversity. The sub-classification was the initiative of Conservation International (CI) in 2003 to identify regions in which at least 70 percent of their original vegetation has remained intact in order to ensure that this is safeguarded and these regions do not become biodiversity hotspots. Currently the areas listed as HBWAs are * Amazon Basin, Brazil * Congo Basin, The Democratic Republic of Congo * New Guinea, Indonesia and Papua New Guinea * North American Deserts, Southwest United States and Mexico * Miombo-Mopane Woodlands and Savannas, Zambia See also *Biodiversity *Conservation biology *Ecoregions *Important Plant Areas *Important Bird Area *International Union for Conservation of Nature *List of types of formally designated forests *Protected ...

High Conservation Value Area
High conservation value forest (HCVF) is a Forest Stewardship Council (FSC) forest management designation used to describe those forests who meet criteria defined by the FSC Principles and Criteria of Forest Stewardship. Specifically, high conservation value forests are those that possess one or more of the following attributes: # forest areas containing globally, regionally or nationally significant: concentrations of biodiversity values (e.g. endemism, endangered species, refugia); and/or large landscape-level forests, contained within, or containing the management unit, where viable populations of most if not all naturally occurring species exist in natural patterns of distribution and abundance # forest areas that are in or contain rare, threatened or endangered ecosystems # forest areas that provide basic services of nature in critical situations (e.g. watershed protection, erosion control) # forest areas fundamental to meeting basic needs of local communities (e.g. subsisten ...

Crisis Ecoregions
A crisis ecoregion is a terrestrial biome facing significant threat to its biodiversity and requiring well directed conservation efforts in order to curb the irreversible loss of plant and animal species and their surrounding habitats. Generally, an ecoregion is understood to be an area of particular ecological importance because of diminishing habitats and ecosystems, but a crisis ecoregion is one that is particularly vulnerable and is listed as 'critical'Jonathan M. Hoekstra, Timothy M. Boucher, Taylor M. Ricketts, and Carter Roberts. Confronting a biome crisis: global disparities of habitat loss and protection. Ecology Letters, 8:23-29, 2005 because of a high Conservation Risk Index (CRI).

Conservation Biology
Conservation biology is the study of the conservation of nature and of Earth's biodiversity with the aim of protecting species, their habitats, and ecosystems from excessive rates of extinction and the erosion of biotic interactions. It is an interdisciplinary subject drawing on natural and social sciences, and the practice of natural resource management. The conservation ethic is based on the findings of conservation biology. Origins The term conservation biology and its conception as a new field originated with the convening of "The First International Conference on Research in Conservation Biology" held at the University of California, San Diego in La Jolla, California, in 1978 led by American biologists Bruce A. Wilcox and Michael E. Soulé with a group of leading university and zoo researchers and conservationists including Kurt Benirschke, Sir Otto Frankel, Thomas Lovejoy, and Jared Diamond. The meeting was prompted due to concern over tropical deforestation, disappearin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Important Bird Area
An Important Bird and Biodiversity Area (IBA) is an area identified using an internationally agreed set of criteria as being globally important for the conservation of bird populations. IBA was developed and sites are identified by BirdLife International. There are over 13,000 IBAs worldwide. These sites are small enough to be entirely conserved and differ in their character, habitat or ornithological importance from the surrounding habitat. In the United States the Program is administered by the National Audubon Society. Often IBAs form part of a country's existing protected area network, and so are protected under national legislation. Legal recognition and protection of IBAs that are not within existing protected areas varies within different countries. Some countries have a National IBA Conservation Strategy, whereas in others protection is completely lacking. History In 1985, following a specific request from the European Economic Community, Birdlife International ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vulnerability
Vulnerability refers to "the quality or state of being exposed to the possibility of being attacked or harmed, either physically or emotionally." A window of vulnerability (WOV) is a time frame within which defensive measures are diminished, compromised, or lacking. The understanding of social and environmental vulnerability, as a methodological approach, involves the analysis of the risks and assets of disadvantaged groups, such as the elderly. The approach of vulnerability in itself brings great expectations of social policy and gerontological planning. Types of vulnerability include social, cognitive, environmental, emotional or military. In relation to hazards and disasters, vulnerability is a concept that links the relationship that people have with their natural environment, environment to social forces and institutions and the cultural values that sustain and contest them. “The concept of vulnerability expresses the multi-dimensionality of disasters by focusing attentio ...
