The classification into over 200 subgroups created problems of needless complexity for forest managers. [citation needed] The Forest Survey of India (FSI), under the aegis of ICFRE, published the Atlas Forest Type of India in 2011. [6] The forest type atlas contained forest type maps for India which were digitised for the first time.
There are about 1361 species of birds recorded from India, with some variations, depending on taxonomic treatments, accounting for about 12% of the world species. [14] There are about 410 species of mammals known from India, which is about 8.86% of the world species. [15] India has the greatest number of cat species in the world. [16]
A\J: Alternatives Journal—based in Ontario, Canada, "Canada's Environmental Voice", website and bimonthly magazine; Earth Negotiations Bulletin—published by the Reporting Services arm of the International Institute for Sustainable Development—covering negotiations, workshops and conferences on a variety of subjects in environmental policy and international law
Although biodiversity loss can be monitored simply as loss of species, effective conservation demands the protection of species within their natural habitats and ecosystems. Following human migration and population growth, species extinctions have progressively increased to a rate unprecedented since the Cretaceous–Paleogene extinction event.
TreeHugger is a sustainability website that reports on news, and other subjects like eco-friendly design, homes, and gardens. It was rated the top sustainability blog of 2007 by Nielsen Netratings, [1] and was included in Time Magazine's 2009 blog index as one of the top twenty-five blogs. [2] The website boasts "over 100 expert writers."
India hosts significant biodiversity; it is home to 7.6% of all mammalian, 12.6% of avian, 6.2% of reptilian, and 6.0% of flowering plant species. [ 8 ] In recent decades, human encroachment has posed a threat to India's wildlife ; in response, a system of national parks and protected areas , first established in 1935, was substantially expanded.
Classification and spatial representation of ecosystems is a major challenge in itself. [30] While a standard taxonomy of organisms has existed for nearly 300 years, [ 31 ] the principles for systematization of ecosystem diversity have only been laid out recently and still require wider adoption.
Species evenness is the relative number of individuals of each species in a given area. [1] Species richness [2] is the number of species present in a given area. Species diversity [3] is the relationship between species evenness and species richness. There are many ways to measure biodiversity within a given ecosystem.
