Coastal and freshwater ecosystems are deteriorating in many areas and at a faster rate than any other ecosystem. Such changes are caused by intertwined factors, making it difficult to identify the problems early on. While progress in integrating these various factors in managing water and ecosystems has been made in some places, the majority of the world and its inhabitants increasingly suffers from a lack of priority given to environmental protection.Resource Type: Reports
This paper reviews the potential for carbon sequestration in dryland ecosystems, which includes forests, but also covers other habitats, such as grasslands, and, importantly, soils. It also considers ways in which carbon storage in drylands affects land degradation issues.Resource Type: Reports
Small local hunting communities in Siberia are very distant from any governmental control. Hunted waterbird species, including globally and regionally threatened species, rely for their well-being on the self regulation of remote hunting communities. Interviewed hunters showed a profound knowledge of Baikal Teal, its population status, and the causes of their past decline. Whether the knowledge is shared by other communities in the region and beyond in Northern Siberia needs verification.
Datasets Available from UNEP-WCMC: Excluding WDPA
Access to UNEP-WCMC datasets is provided on the understanding that you read and consent to be bound by the Terms and Conditions attached. For the purposes of this Agreement the “Data” comprise any of the spatial data and associated attribute data downloadable from the UNEP-WCMC website, excluding the World Database on Protected Areas.
This dataset provides spatial representation for the 234 “Data Sheet Sites” in the Centres of Plant Diversity (Davis et al. 1994-1997). In addition to the 234 priority sites selected for Data Sheet Site treatment, the Centres of Plant Diversity volumes recognize a number of additional sites in the Regional Summaries, but these are not included here. Theoretically, based on spatial information provided for some non-Data Sheet Sites in the CPD volumes (or even just the name of the sites in many cases), it would be possible to map many non-Data Sheet Sites. However, it would be difficult to do so consistently, and, furthermore, only the Data Sheet Sites are based on actual criteria. Specifically, to qualify for “Data Sheet” treatment in the volumes, mainland sites must have >1000 vascular plants, of which at least 100 are endemic to the site or to the phytogeographical region in which the site occurs; island floras must contain at least 50 endemic species or at least 10% of the flora must be endemic.

This study demonstrates the utility of carbon isotope discrimination in describing genetic adaptation to arid environments, although it is probably most useful in detecting differentiation when the strategy of the species under investigation is to increase water use efficiency, rather than drought-avoidance. The results suggest that populations on the eastern and western sides of the Andes should be treated as separate management units for the purposes of conserving the genetic resource of this species.Resource Type: Journal Papers
Arctic Flora and Fauna: Status and Conservation is the first truly circumpolar overview of Arctic biodiversity written for the nonspecialist. It provides the reader with a clear understanding of the importance of the Earth's largest ecoregion and its status in the face of a rapidly changing world.Resource Type: Reports
An international team of research scientists has created a peer-reviewed website, http://www.arctic.noaa.gov/reportcard/, which tracks multiple changes in the Arctic environment (Fig. 1). While the 2007 loss of summertime sea ice is the most dramatic example, changes are also seen in the atmosphere, on land and in the ocean, and as shifts in location and abundance of Arctic species.Resource Type: Reports
Our results show that any further infrastructure development will put the remaining European population of wild mountain reindeer at great risk, as further habitat fragmentation will make the remaining undisturbed patches too small for holding viable populations. We discuss the importance of controlling piecemeal development in infrastructure for conservation of wildlife and argue that minimizing infrastructure development is likely one of the largest challenges in wildlife conservation ahead.Resource Type: Journal Papers
The Great Apes, including the chimpanzee, gorilla and orangutan, are threatened with extinction. All species are rapidly declining in abundance, even within protected areas.The main factors responsible for this decline are loss and degradation of habitat, and hunting. Construction of roads in forest areas is particularly damaging, as such development facilitates hunting and other activities which lead to habitat destruction.
This report assesses the impact of infrastructural development on great ape populations, using the GLOBIO modelling approach. GLOBIO is a multivariable spatial model, which estimates the extent of land area with reduced abundance and diversity of living organisms, as a result of infrastructural development. The model can also be used to develop scenarios of possible future impacts, based on the current rates of infrastructural development.Resource Type: Reports
