  Seriously Declining Trends in Migratory Waterbirds: Causes - Concerns – Consequences »

  The scope of this report is to present trends of 34 waterbird species for the International Wadden Sea and the four surrounding regions - the Netherlands, the federal states of Germany, Niedersachsen and Schleswig-Holstein, and Denmark.

  Reconstructing the movements of free-ranging demersal Fish in the North Sea: a data-matching and simulation method »

  Demersal fish cannot be readily tracked using data loggers that provide satellite-based or light-based geolocation. Moreover, fish that are highly mobile within the water column cannot readily be located with other methods, such as the tidal location method (TLM). As an alternative, we describe a process that provides estimates of geographic location by simulating movement paths through geographic locations that match temperature and depth data recorded by data loggers.

  Biodiversity trends in Europe: development and testing of a species trend indicator for evaluating progress towards the 2010 target »

  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.

  Priorities for conserving global species richness and endemism »

  Projections 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.

  Restoration of wooded landscapes: placing U.K. initiatives in a global context »

  This publication comprises the proceedings of the conference ‘The Restoration of Wooded Landscapes’, held at Heriot Watt University in September 2000. The principle aim of the conference was to bring together researchers, practitioners and policymakers to allow a full and free exchange of views, information and ideas on the theme of native woodland restoration at the landscape scale (areas in excess of 1 km2). This includes creating new native woodland, restoring planted ancient woodland, and expanding existing native woodlands.

  Mapping potential biodiversity benefits from REDD+. The Democratic Republic of the Congo »

  REDD+, as discussed by the United Nations Framework Convention on Climate Change, is a mechanism to incentivise Reducing Emissions from Deforestation and forest Degradation, as well as the conservation of forest carbon stocks, sustainable management of forests and the enhancement of forest carbon stocks. Actions under REDD+ can potentially provide biodiversity benefits, but there is also a need to avoid any risks of environmental harms from REDD+. A new report, launched in Kinshasa on 5 July 2012, presents selected results of spatial analyses to explore potential biodiversity benefits and risks from REDD+ in the Democratic Republic of the Congo. The report is the output of a collaboration between the DRC’s Direction des Inventaires et Aménagement Forestiers (DIAF) of the Ministère de l'Environnement, Conservation de la Nature et Tourisme, the Observatoire Satellital des Forêts d’Afrique Centrale (OSFAC) and the United Nations Environment Programme World Conservation Monitoring Centre (UNEP-WCMC), with support from the UN-REDD Programme.

  Distribution and conservation status of the orang-utan ( Pongo spp.) on Borneo and Sumatra: how many remain? »

  in 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.
