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: BooksThis atlas provides a comprehensive overview of what is currently known about all six species of great apes - chimpanzee, bonobo, Sumatran orangutan, Bornean orangutan, eastern gorilla, and western gorilla. It gives a thorough background on ape behaviour and ecology for each species, including detailed habitat requirements, the apes' ecological role, and the possible consequences of their decline.
Despite the dedicated efforts of many individuals and organizations, the great apes all fall into the Endangered or Critically Endangered category of the IUCN Red List. This atlas offers a full description of the threats, current conservation efforts, and additional protection needed for each species across its entire range.
•Covers all six species of great apes
•Provides the most up-to-date and comprehensive data available
•More than 150 full-colour photos
•More than 40 full-colour maps and diagrams

We made a complete survey of all the extant populations in Djibouti and to collect samples for genetic analysis with a view conserving the palm for the future.
Our survey revealed that there were a total of 314 adults, 20 juveniles, 134 rosettes, 210 small rosettes (more than 6 leaves) and 465 seedlings (<3 leaves) living in the Bankouale area of Djibouti. These are distributed unequally amongst three valley systems. 65% of the adults, 85% of the juveniles, 75% of the rosettes, 76% of the small rosettes, and 93 % of the seedlings were found in the Bankouale valley.
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: ReportsThe 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: ReportsThe Last Stand of the Orangutan was prepared by a Rapid Response Team at UNEP/GRID-Arendal and UNEP World Conservation Monitoring Centre as a broad collaborative effort, involving contributors from the Ministry of Environment and Ministry of Forestry, Indonesia, and partners of the Great Apes Survival Project (GRASP).
