Seagrasses are unique as they are the only marine flowering plants. Seagrass beds form complex physical structures and are a highly productive ecosystem. This enables them to support a considerable biomass and diversity of associated species. For the first time the World Atlas of Seagrasses summarises the opinion and science of the world's leading experts on the global status of the ecosystem.
The Atlas is a collaboration of more than 50 authors from 25 nations. Fully illustrated, the Atlas contains the first global and regional maps of seagrass distribution and a wealth of information on key issues concerning this 'forgotten' ecosystem.Resource Type: Books
UNEP-WCMC produces reports for a number of fora including CITES, the European Commission and the Convention on the Conservation of Migratory Species of Wild Animals (CMS). Recent examples of these reports can be downloaded here in PDF format.Resource Type: Reports
A reduction in forest area should result in a reduction of its number of species and, moreover, do so in a characteristic way according to the familiar species-area relationship. Brooks, Pimm & Collar (1997) applied this formula to the losses in forest area in the Philippines and Indonesia. Independently derived totals of the number of endemic bird species that are threatened with extinction broadly agree with these predicted losses. In some cases, however, predicted losses overestimate or underestimate the actual numbers of threatened species.Resource Type: Journal Papers
These posters were designed to highlight the work of the 'Wings over Wetlands' project of the AEWA Convention - Agreement on the Conservation of African-Eurasian Migratory Waterbirds.Resource Type: Posters
This atlas provides a comprehensive overview of what is currently known about all six species of great apes - chimpanzee, bonobo, Sumatran orangutan, Bornean orangutan, eastern gorilla, and western gorilla. It gives a thorough background on ape behaviour and ecology for each species, including detailed habitat requirements, the apes' ecological role, and the possible consequences of their decline.
Despite the dedicated efforts of many individuals and organizations, the great apes all fall into the Endangered or Critically Endangered category of the IUCN Red List. This atlas offers a full description of the threats, current conservation efforts, and additional protection needed for each species across its entire range.
•Covers all six species of great apes
•Provides the most up-to-date and comprehensive data available
•More than 150 full-colour photos
•More than 40 full-colour maps and diagrams
Datasets Available from UNEP-WCMC: Excluding WDPA
Access to UNEP-WCMC datasets is provided on the understanding that you read and consent to be bound by the Terms and Conditions attached. For the purposes of this Agreement the “Data” comprise any of the spatial data and associated attribute data downloadable from the UNEP-WCMC website, excluding the World Database on Protected Areas.
The seagrass dataset has been compiled by UNEP-WCMC in collaboration with Dr Frederick T. Short, University of New Hampshire, USA to show the global distribution of seagrass species. This dataset has been created from multiple sources and was used in the creation of the "World Atlas of Seagrasses" (2003). This polygon feature dataset is an update of the data used in the Atlas and is a unique data holding about the state of the world's seagrasses. For a complete overview of global seagrass distribution this dataset should be displayed together with the associated point dataset.
The Critical Site Network (CSN) Tool is a new online resource for the conservation of 294 species of waterbirds and the important sites upon which they depend in Africa and Western Eurasia. Leading global conservation organisations working for the protection of waterbirds and their habitats have joined forces to develop this tool, strengthening the implementation of the African-Eurasian Migratory Waterbird Agreement (AEWA) and the Ramsar Convention on Wetlands.Resource Type: Tools / Applications
Assuming no radical transformation in human behavior, we can expect important changes in biodiversity and ecosystem services by 2050. A considerable number of species extinctions will have taken place. Existing large blocks of tropical forest will be much reduced and fragmented, but temperate forests and some tropical forests will be stable or increasing in area, although the latter will be biotically impoverished. Marine ecosystems will be very different from today's, with few large marine predators, and freshwater biodiversity will be severely reduced almost everywhere. These changes will not, in themselves, threaten the survival of humans as a species.Resource Type: Journal Papers
Sustainability requires living within the regenerative capacity of the biosphere. In an attempt to measure the extent to which humanity satisfies this requirement, we use existing data to translate human demand on the environment into the area required for the production of food and other goods, together with the absorption of wastes. Our accounts indicate that human demand may well have exceeded the biosphere's regenerative capacity since the 1980s. According to this preliminary and exploratory assessment, humanity's load corresponded to 70% of the capacity of the global biosphere in 1961, and grew to 120% in 1999.Resource Type: Journal Papers
