This eight volume series, developed for use by decision-makers, mid-career professionals, and interested parties, reviews the issues and processes involved in the management of biodiversity information to support the conservation and sustainable use of living resources. They also provide a framework for the development of national plans and strategies and for meeting reporting obligations of international programmes and conventions.Resource Type: Reports
Aquilaria malaccensis (Thymelaeaceae) is the principal source of gaharu, one of the most valuable tropical forest products in international trade. Despite its economic importance, the autecology of this species is virtually unknown. Seedling growth and survival of A. malaccensis was monitored over a 15-month period in natural forest in West Kalimantan. Mean height growth rate was 21.2 + 2.3 cm year1, and was positively related to light availability (i^= 0.79, p < 0.001), but unrelated to distance to the nearest mature tree or seedling density. By the end of the observation period, fewer than 20% of seedlings surveyed initially were still alive, trampling and cutting being one of the main causes of mortality. A nursery experiment examined the influence of soil (two treatments), light availability (four treatments) and seedling density (four treatments) on growth. Although a decrease in irradiance was associated with significantly (p < 0.01, t - test) lower values for height and stem diameter, seedlings were able to survive under the low light treatment. Lower height growth rates and leaf increment were observed with higher seedling densities on the more fertile soil; no such effects of density were observed on the relatively infertile soil. The implications of these results for the sustainable management of A. malaccensis are discussed.Resource Type: Journal Papers
As the importance of mountain spaces is more widely recogised, it seems necessary to establish a coherent definition of these spaces. The UNEP World Conservation Monitoring Centre (UNEP-WCMC) proposed the first global delineation in 2000. However, certain European countries have used national definitions of mountain spaces since the 1950s. Within the framework of social and economic integration policies at the heart of the European Union, an agreed delineation of European mountain spaces has been established, based on the definition proposed by UNEP-WCMC. The process of adaptation of the global definition to the European context is described, as well as the results for 29 European countries.Resource Type: Journal Papers
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.Resource Type: Journal Papers
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.Resource Type: Journal Papers
The Atlas begins with contributions from experts in many geographical fields, providing detailed information on the key issues facing the world today - climate change, environmental threats, global communications, biodiversity and energy resources - with supporting maps, images, photographs and graphics to illustrate the physical world today and man's interaction with it.
For this new edition, all the maps and detailed thematic information are updated with the latest geographical and geo-political changes - these include an estimated 20,000 updates with 3,500 changes to place names and are illustrated with the latest satellite imagery.
Although Asian bamboo species constitute a non-timber forest product of major cultural and economic importance, no detailed regional assessment of their distribution patterns has previously been made. To assess the potential of the existing bamboo species distribution data for production of regional mapping tools for planning the conservation of forest-based biodiversity, data on bamboo distribution and forest cover were combined. Over 1000 bamboo species from 60 genera of woody bamboos were incorporated, allowing the mapping of individual species or groups of species and genera, along with potential species richness and biodiversity hotspots. Over 6.3 million km2 of Asian forest potentially contains bamboo, with highest densities indicated from northeastern India through Burma to southern China, and through Sumatra to Borneo. The highest figures for potential species richness (144 spp per square km) were recorded in forests of south China, including Hainan Island. Despite substantial inadequacies and inconsistencies in knowledge of the taxonomy and distribution of bamboo species, this approach may provide a valuable tool for planning in situ conservation of forest biodiversity.Resource Type: Journal Papers
The study reviews the situation regarding Protected Area extent, legal status and management constraints in each country and territory of East Asia, using a regional review and gap analysis by applying a simple GIS overlay approach. The WDPA has available a near complete GIS cover of PAs in the region and most large PAs are represented by polygons (boundary information). A few large PAs and many very small PAs are represented by circles of correct area around known centre points of the PAs held in the database.
The Global and Regional Assessments of the Marine Environment Database (GRAMED) has been developed at the request of UNEP and IOC/UNESCO, as the lead agencies responsible for taking forward the "Assessment of Assessments" through the implementation of UNGA Resolution 60/30. It was first developed to support the preparation of the 2007 report, Global Marine Assessments: A survey of global and regional assessments and related scientific activities of the marine environment and builds on the 2003 UNEP-WCMC/UNEP/ IOC-UNESCO report "Global Marine Assessments: A survey of global and regional marine environmental assessments and related scientific activities".Resource Type: Tools / Applications
There are several things environmental managers need to know for a practical understanding. For instance:
What exactly does the information from a particular satellite sensor represent?
How can this information be translated into a useful indicator?
What are the common indicators associated with each major biome?
What range of accuracy might one expect from a particular remotely sensed indicator, and what
conditions affect this accuracy?
We address these and other questions while presenting the overall role that remote sensing can play for developing and monitoring biodiversity indicators relevant to various strategic components of the Convention on Biological Diversity (CBD).Resource Type: Reports
