The objectives of the World Heritage Convention are the identification, protection, conservation and presentation of the world's natural and cultural heritage and ultimately, the successful transmission of them to future generations. UNEP-WCMC and IUCN have undertaken a range of global and regional studies to support State Parties to the Convention in the selection of potential sites, and to assist in the evaluation of nominations.Resource Type: Reports

Sustainability requires living within the regenerative capacity of the biosphere. In an attempt to measure the extent to which humanity satisfies this requirement, we use existing data to translate human demand on the environment into the area required for the production of food and other goods, together with the absorption of wastes. Our accounts indicate that human demand may well have exceeded the biosphere's regenerative capacity since the 1980s. According to this preliminary and exploratory assessment, humanity's load corresponded to 70% of the capacity of the global biosphere in 1961, and grew to 120% in 1999.Resource Type: Journal Papers
We applied a conceptual framework and score-card developed by the Cambridge Conservation Forum (CCF) to a sample of 60 conservation activities to determine the predictive power of implementation measures versus measures of key outcomes (later steps in the models defined in the CCF tools). We show that assessing key outcomes is often more difficult than quantifying the degree of implementation of a project but that, while implementation is a poor predictor of success, key outcomes provide a feasible and much more reliable proxy for whether a project will deliver real conservation benefits. The CCF framework and evaluation tool provide a powerful basis for synthesizing past experience and, with wider application, will help to identify factors that affect the success of conservation activities.Resource Type: Journal Papers
The United Nations List of Protected Areas is an essential reference document for all who want to understand the progress made in responding to the challenges of biodiversity loss and other environmental threats around the world. It is a record of extraordinary human achievement over 125 years - a commitment by nations, peoples, groups and individuals to safeguard areas of land and sea from destruction. Protected areas represent human ideals at their best - they express a long term vision and a broad sense of responsibility towards people and nature.
This version of the list is the twelfth in a series, each recording steady expansion in the total area protected. There are now some 12,754 areas in the UN List, covering almost 8% of the land surface of the world (a far smaller proportion of the oceans is protected). Compared to the previous, 1993 edition of the of the UN List, this report includes 2,933 more sites covering 3.9 million more square kilometres. At the end of the century it can be said that practically every country has protected areas; some have a very sophisticated network of sites.Resource Type: Reports
The success of protected areas as a tool for conservation is based around the assumption that they are managed to protect the values that they contain. To be effective, management should be tailored to the particular demands of the site, given that each protected area has a variety of biological and social characteristics, pressures and uses. Achieving effective management is not an easy task – it requires adopting appropriate management objectives and governance systems, adequate and appropriate resourcing and the timely implementation of appropriate management strategie and processes. It is unlikely to be achieved fully without an approach to management that is inquiring an reflective – that seeks to understand how effective the current management regime is and how it could be improved. Information on management effectiveness is thus a cornerstone of good management.
Over the past 10 years a number of studies and consultations have been carried out to develop and refine the Global Strategy for achieving a balanced, representative and credible World Heritage List that reflects the world’s diverse heritage. This review is an important addition to that process, focusing on the inter-related elements of biogeography, habitats and biological diversity that underpin much of what we consider ‘natural heritage’.Resource Type: Reports
Our analyses show significant differences between predictions from different models, with predicted changes in range size by 2030 differing in both magnitude and direction (e.g. from 92 loss to 322 gain). We explain differences with reference to two characteristics of the modelling techniques: data input requirements (presence/absence vs. presence-only approaches) and assumptions made by each algorithm when extrapolating beyond the range of data used to build the model. The effects of these factors should be carefully considered when using this modelling approach to predict species ranges. Main conclusions We highlight an important source of uncertainty in assessments of the impacts of climate change on biodiversity and emphasize that model predictions should be interpreted in policy-guiding applications along with a full appreciation of uncertainty.Resource Type: Journal Papers
The effects of Pleistocene glaciations on the genetic characteristics of the most austral conifer in the world, Pilgerodendron uviferum, were analysed with specific reference to the hypothesis that the species persisted locally in ice-free areas in temperate South America.
Results indicated that Pilgerodendron populations are highly monomorphic, probably reflecting past population bottlenecks and reduced gene flow. Southernmost populations tend to be the least genetically variable and were therefore probably more affected by glacial activity than northern ones. Populations located outside ice limits seem to have been isolated during the glacial period. The presence of centres of genetic diversity, together with the lack of a significant correlation between genetic and geographical distances and the absence of geographical patterns of allelic frequencies at most analysed alleles, may indicate that Pilgerodendron did not advance southward after the last glaciation from a unique northern refugium, but spread from several surviving populations in ice-free areas in Patagonia instead.Resource Type: Journal Papers
