This paper presents a trial of a species population trend indicator for evaluating progress towards the 2010 biodiversity target in Europe, using existing data. The indicator integrates trends on different species (groups), and can be aggregated across habitats and countries. Thus, the indicator can deliver both headline messages for high-level decision-making and detailed information for in-depth analysis, using data from different sources, collected with different methods.
Resource Type: Journal PapersProjections indicate that species and ecosystems will be at maximum risk from human activities during the next few decades. Prompt action by the world community can minimise the eventual loss of species. Highest priorities should be to: (i) strengthen the management of ecosystems containing a large proportion of global biodiversity; (ii) help developing countries complete their biodiversity strategies and action plans, monitor their own biodiversity, and establish and maintain adequate national systems of conservation areas; (iii) support actions at the global level, providing benefit to all countries in managing their own biodiversity. Generally, resources will best be spent in safeguarding ecosystems and habitats that are viable and important for global biodiversity, and which are threatened by factors that can be controlled cost-effectively. Other important criteria are representativeness, complementarity and insurance.
Resource Type: Journal PapersThis paper is based on a feasibility study on the monitoring of rare tropical timber species in international trade.
Resource Type: ReportsA UN-REDD workshop on ‘Identifying and promoting ecosystem co-benefits from REDD+’ was held from 27th-29th April 2010 in Cambridge, UK, convened by UNEP-WCMC. Forty-four people participated in the workshop, including representatives from five UN-REDD pilot countries, one observer country, and a number of different institutions, agencies and NGOs.
Resource Type: Reportsin 2004 there were c. 6,500 P. abelii remaining on Sumatra and at least 54,000 P. pygmaeus on Borneo. Extrapolating to 2008 on the basis of forest loss on both islands suggests the estimate for Borneo could be 10% too high but that for Sumatra is probably still relatively accurate because forest loss in orang-utan habitat has been low during the conflict in Aceh, where most P. abelii occur. When those population sizes are compared to known historical sizes it is clear that the Sumatran orang-utan is in rapid decline, and unless extraordinary efforts are made soon, it could become the first great ape species to go extinct. In contrast, our results indicate there are more and larger populations of Bornean orang-utans than previously known.
Resource Type: Journal PapersOur analyses show significant differences between predictions from different models, with predicted changes in range size by 2030 differing in both magnitude and direction (e.g. from 92 loss to 322 gain). We explain differences with reference to two characteristics of the modelling techniques: data input requirements (presence/absence vs. presence-only approaches) and assumptions made by each algorithm when extrapolating beyond the range of data used to build the model. The effects of these factors should be carefully considered when using this modelling approach to predict species ranges. Main conclusions We highlight an important source of uncertainty in assessments of the impacts of climate change on biodiversity and emphasize that model predictions should be interpreted in policy-guiding applications along with a full appreciation of uncertainty.
Resource Type: Journal PapersThis study assesses the global trade in coral in an ecological and economic context. Throughout the report emphasis is placed on the trade in live coral for aquaria because the last decade has seen an enormous increase in this business. The taxonomic composition of the trade is identified and the quantities of coral passing between nations illustrate the links between major exporters and importers. Subsequent chapters present data on the practicalities of monitoring international trade in coral at the global scale. Size and growth rate data are used to assess the sustainability of the trade in live coral, and export and retail prices are used to estimate the revenue to exporting nations.
Resource Type: ReportsFrom Ocean to Aquarium is the product of a collaboration between UNEP-WCMC, the Marine Aquarium Council (MAC) and the industry itself. It is the first of its kind, examining issues surrounding the trade of live coral, fish and invertebrates for the marine aquarium trade, and presenting a comprehensive and independent synthesis of related information.
