  Conservation and sustainable use of tropical trees in the genus Aquilaria II. The impact of gaharu harvesting in Indonesia »

  Aquilaria spp. are the main source of gaharu, one of the most valuable non-timber products harvested from tropical forests. In order to assess the impact of gaharu harvesting on populations of Aquilaria spp. in Indonesia, the activities of gaharu collectors were assessed by accompanying them on collecting expeditions.

  Given current harvesting practices, it is unlikely that gaharu is being sustainably harvested at present. The results suggest that the gaharu trade may have had a substantial impact on the population size of Aquilaria spp. in Indonesia, and their implications are discussed in the context of setting harvest quotas for regulation of trade, as required by CITES.

  Regeneration and stand dynamics of Fitzroya cupressoides (Cupressaceae) forests of southern Chile's Central Depression »

  Several populations of Fitzroya cupressoides (Mol.) Johnst. (Cupressaceae, common name 'alerce'), a threatened, long-lived conifer endemic to southern Chile and parts of Argentina, have recently been found in Chile's Central Depression, where the species was thought to have been extirpated. The objective of this study was to determine, on eight sites in the Depression, Fitzroya's regeneration behavior in relation to disturbance, its substrate and cover requirements for establishment, and whether regeneration is by seed or vegetative means.

  Despite substantial environmental differences between the Central Depression and the portions of the Coastal and Andean Cordilleras where Fitzroya is found, populations in all three regions show striking similarities in their regeneration and stand dynamics. Fitzroya's longevity and at times abundant regeneration provide the biological basis for its persistence in Chile's Central Depression.

  Guidance for National Biodiversity Indicator Development and Use »

  This guidance is designed to help the development of biodiversity indicators at the national level for uses such as reporting, policy-making, environmental management, and education. It is intended principally for the people who produce biodiversity indicators, whether they are in government agencies, academia or NGOs. In some cases biodiversity indicators are developed on a ‘one-off’ basis to meet the needs for a particular study or report, or they can be developed for long-term reporting and decision-making. This guidance can be used for both situations.

  IUCN Red List Index: Guidance for national and regional use »

  This guidance document to support national and regional use of the IUCN Red List Index is a product of the IUCN Red List of Threatened Species™. It has been developed by IUCN and its partner organizations. Support for the production of this document has been provided by the 2010 Biodiversity Indicators Partnership (www.twentyten.net).

  Crossroads of Life on Earth - Exploring means to meet the 2010 Biodiversity Target »

  The aim of this assessment study was to explore policy options under current discussion in the global political arena that could have major positive or negative impacts on biodiversity. The central concern of the assessment is the achievement of the 2010 Biodiversity Target at global and regional levels, as agreed upon under the Convention on Biological Diversity (CBD).

  Effects of artificial shade on attack by the mahogany shoot borer, Hypsipyla robusta (Moore) »

  Swietenia macrophylla King (Meliaceae: Swietenioideae) provides one of the premier timbers of the world. The mahogany shoot borer Hypsipyla robusta Moore (Lepidoptera: Pyralidae) is an economically important pest of S. macrophylla throughout Asia, Africa and the Pacific. No viable method of controlling this pest is known. Previous observations have suggested that the presence of overhead shade may reduce attack by H. robusta, but this has not been investigated experimentally. This research was therefore designed to assess the influence of light availability on shoot-borer attack on S. macrophylla, by establishing seedlings under three different artificial shade regimes, then using these seedlings to test oviposition preference of adult moths, neonate larval survival and growth and development of shoot borer larvae.

  The results indicate that shading of mahogany seedlings may reduce the incidence of shoot borer attack, by influencing both oviposition and larval development. The establishment of mahogany under suitable shade regimes may therefore provide a basis for controlling shoot borer attack using silvicultural approaches.

  Coverage of protected areas: Guidance for national and regional use »

  This guidance document is one of a series produced with the support of the 2010 Biodiversity Indicators Partnership (2010 BIP) to assist Parties to the Convention on Biological Diversity (CBD) to track their progress towards the 2010 BiodiversityTarget. Coverage of Protected Areas has been selected as one of the indicators suitable for assessing progress towards and communicating the 2010 Target at the global level. The aim of this document is to provide guidance to support the calculation and interpretation of the Coverage of Protected Areas indicator at the national and regional scales.

  The Living Planet Index - Guidance for National and Regional Use »

  This guidance document is one of a series produced with the support of the 2010 Biodiversity Indicators Partnership (2010 BIP) to assist Parties to the Convention on Biological Diversity (CBD) track their progress towards the CBD’s 2010 Target. The Living Planet Index (LPI) has been selected as one of the indicators suitable for assessing progress towards and communicating the 2010 Target at a global level. The aim of this document is to provide information to support the calculation and interpretation of the Living Planet Index at the national and regional scales.

  International Expert Workshop on the 2010 Biodiversity Indicators and Post-2010 Indicator Development »

  In July 2009, the Secretariat of the Convention on Biological Diversity (SCBD) and the UNEP World Conservation Monitoring Centre jointly convened a meeting to review the use and effectiveness of the 2010 biodiversity indicators and to consider the implications for the development of post-2010 targets and indicators.  This is a summary of that meeting.

  Linking Biodiversity Conservation and Poverty Alleviation: A State of Knowledge Review »

  Over recent decades, biodiversity conservation and poverty reduction have both become international societal and political goals. There is recognition of the links between these two goals both within the Convention on Biological Diversity and the Millennium Development Goals. However, the causal relationships are not so simple either that one can say poverty causes biodiversity loss, or improvements in biodiversity reduce poverty. This suggests a need to be more specific in defining what types of poverty and biodiversity issues are being assessed.

  Two “state of knowledge” reviews were commissioned to explore the evidence base for two common assumptions about the link between biodiversity conservation and poverty reduction: 1) that the poor depend on biodiversity; and 2) that biodiversity conservation can be a mechanism for poverty reduction. These attempt to tease apart the issues of what type of poverty and what type of biodiversity are being assessed.
