Seagrasses are unique as they are the only marine flowering plants. Seagrass beds form complex physical structures and are a highly productive ecosystem. This enables them to support a considerable biomass and diversity of associated species. For the first time the World Atlas of Seagrasses summarises the opinion and science of the world's leading experts on the global status of the ecosystem.
The Atlas is a collaboration of more than 50 authors from 25 nations. Fully illustrated, the Atlas contains the first global and regional maps of seagrass distribution and a wealth of information on key issues concerning this 'forgotten' ecosystem.Resource Type: Books
The Environmental Management Group (EMG). in 2004, decided to focus its attention on environmental capacity building, following concerns of UN agencies and multilateral environmental agreements (MEAs) in this area. Consultants were asked to prepare draft studies for the further work of the EMG on capacity building in the areas of biological diversity and chemicals, respectively. The draft studies were further developed following discussions in the EMG and an Issue Management Group established by the EMG. This paper is the result of these discussions for the area of capacity building for biological diversity.Resource Type: Reports
Since the late 1970s the UNEP World Conservation Monitoring Centre (UNEP-WCMC) has delivered services that support implementation of international biodiversity-related agreements at global, regional and national levels. These services not only support the work of the agreement secretariats, but also of the advisory and governance bodies, and of governments party to the various agreements. The aim of this paper is to illustrate this work through examples of work we have undertaken.
The support that UNEP-WCMC provides is based on expert understanding of the agreements and how they work, resulting from many years of experience and close relationships with secretariats.Resource Type: Reports
Written by UNEP-WCMC and UNEP-FI, this paper provides an overview of biodiversity offsets as a mitigation mechanism and examples of the different types of global regulatory and voluntary initiatives adopting this concept, as well as highlighting some existing challenges and opportunities.Resource Type: Reports
National Parks and other protected areas not only provide a safe haven for biodiversity, they provide benefits to local communities and preserve some of the most beautiful places on our planet. ‘Coverage of protected areas’ is also a specific indicator in the 2010 Target of the Convention on Biological Diversity.
Obtaining the data necessary to monitor trends in protected areas requires a massive effort by national authorities to compile, analyse and then distribute this data to the centralised depository of the World Database on Protected Areas (WDPA). With a living and growing system of protected areas that now exceed 100,000 sites covering 19 million square kilometres, you can imagine that this is no small task!
Produced jointly between UNEP-WCMC and UNEP’s Division of Technology, Industry and Economics, this document reviews the business case for biodiversity; provides an overview of impacts by sector and highlights existing and potential opportunities for companies. The document covers a wide range of sectors and complements existing and ongoing work on business and biodiversity.Resource Type: Reports
The forests of eastern Tanzania are a globally important biodiversity hotspot. In this study 361 eastern Tanzanian restricted range forest tree taxa were assessed. Of these taxa, 223 occurred in the Eastern Arc, 150 in Coastal forests, 17 in Northern forests and 21 in the Lake Nyasa forests. The majority of the taxa had restricted elevational ranges with 76.3 occurring in no more than two 200 m elevational bands out of a total potential elevation range of 3000 m. The majority of the taxa occupied a small area in the eastern Tanzanian forests, with 201 taxa being only found at a few sites. In determining priority areas for conservation, selection of taxon definitions can have important effects. For example, tree size varies with elevation, so if only large trees are used then site selection will be biased towards particular areas.Resource Type: Journal Papers
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
Tropical trees in the genus Aquilaria Lam. are the principal source of gaharu, one of the most valuable forest products traded internationally. Although these species are the focus of increasing conservation concern, information on their status and distribution is lacking. Information from herbarium accessions, a national forest inventory (NFI), field surveys and gaharu traders was used to assess the distribution of Aquilaria species in Indonesia, indicating population concentrations in Sumatra and eastern Kalimantan.
Given current deforestation rates, these data suggest that all Aquilaria species in Indonesia classify as Vulnerable according to the IUCN Red List criteria.Resource Type: Journal Papers
