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
In the past few years, a number of analyses have been undertaken to measure progress towards the 2010 and 2012 CBD targets. This report demonstrates how the measurement of progress is influenced by decisions on which protected areas are included (for instance, whether internationally designated sites, or sites without an assigned IUCN category are included) and which biogeographic datasets used (for instance which mountain dataset is chosen), and highlights the need for standardised methods and datasets.Resource Type: Journal Papers
Two recent analyses have measured protected area coverage for each of the world’s realms, biomes and ecoregions - UNEP-WCMC, 2008 and Jenkins and Joppa, 2009 Expansion of the global terrestrial protected area system, Biological Conservation 142 (2009), pp. 2166–2174, using the WWF Terrestrial Ecoregions of the World.
However, data handling procedures differ between these analyses, resulting in differences in the protection statistics reported. Here we outline differences in the use of datasets, present alternative analyses of the protected area coverage of WWF realms, biomes and ecoregions for 2009, and compare the two estimates of protected area coverage.
Protected areas can act as a case study for REDD: lessons can be learnt from their success or otherwise in reducing deforestation and supporting local livelihoods. Further research into the most effective management and governance frameworks for acheiving goals on carbon emissions, biodiversity and communities, and the extent to which protected areas reduce (or merely displace) deforestation within national boundaries would be useful in informing REDD implementation.Resource Type: Journal Papers
UNEP-WCMC and IUCN, with support from UNESCO, compile information sheets for all properties inscribed on the World Heritage List for natural or mixed (natural and cultural) reasons. These sheets are usually prepared following the inscription of a property on the World Heritage List. The sheets are updated from time to time. The latest available sheets are published on this webpage.Resource Type: Reports
Protected areas (PAs) are the cornerstone of global conservation efforts but their performance in maintaining populations of their key species remains poorly documented. Here, we address this gap using a new database of 583 population abundance time series for 69 species of large mammals in 78 African PAs.Resource Type: Journal Papers
Marine conservation lags behind terrestrial in the establishment of protected areas. This was recognized by the Convention on Biological Diversity, whose members, in 2004, agreed to establish “comprehensive, effectively managed, and ecologically representative” systems of marine protected areas (MPAs) by 2012. Halfway toward this target date, we look at the coverage of the world’s 5045 MPAs from a biogeographic perspective.Resource Type: Journal Papers
This paper explores the political ecology of conservation, particularly the establishment of PAs. It discusses the implications of the idea of pristine nature, the social impacts of and the politics of PA establishment and the way the benefits and costs of PAs are allocated. It considers three key political issues in contemporary international conservation policy: the rights of indigenous people, the relationship between biodiversity conservation and the reduction of poverty, and the arguments of those advocating a return to conventional PAs that exclude people.Resource Type: Journal Papers
Information on elephant ranges and numbers is vital for their effective conservation and management. This is especially true in West Africa where elephant populations are small and scattered. Digya National Park in Ghana is home to some of the least studied elephant populations in Africa. A dung count of the Digya elephant population was conducted to determine the density and distribution of elephants in the park using a systematic segmented track line design.
The mean density of dung-piles was 323 dung-piles per sq km and mean dung survival time was estimated to be 44 days (SD = 2.0 days). An estimated 341±53 (95% confidence interval) elephants with density of 0.41 elephants/km2 were obtained in the study. This makes the Digya elephant population the second largest in Ghana. Elephants occurred mainly in the south-western forested part of the park. This may be related to local abundance of wild fruits and/or conflict with squatters in other parts of the park. The possibility of the estimate being higher has been discussed. This current baseline information augments the Regional Elephant Database and should facilitate strategic planning and management programmes.
The expansion of Protected Areas systems is urgently needed to ensure that further biodiversity losses do not occur. The need to evaluate the effectiveness of protected area management has become well recognized over the past ten years, as we have seen that declaration of protected areas does not always result in their adequate protection. Assessments have been carried out for different purposes, differing in methodology, geographic and topical scope. In order to assist in the harmonization and application of different systems through the WCPA Framework, the IUCN-WCPA is carrying out a global review of management effectiveness assessments.Resource Type: Journal Papers
