The efforts and activism of experts in conservation biology greatly contributed to the emergence, dissemination and success of the notion "biodiversity", which has now become a buzzword as noted by Takacs (1996). But how should we interpret the widespread acceptance by the scientific community of a notion that is often considered a hodge podge of ideas?

Ecological corridors are a fundamental element in the National ecological network approved by the Grenelle environmental agreement in order to reduce ecosystem damage caused by fragmentation of the natural habitat zones of species. How can their effectiveness be evaluated? This article sums up current knowledge on their pros and cons.

Similar to many other European countries, Finnish landscapes underwent profound change during the 1900s due to modifications in forest management. The changes in landscapes produced the current situation in which a significant number of forest animal species are threatened.

Is it possible to produce more wood while better preserving forest biodiversity? The question raises major issues in light of the energy situation. This study points out the limits to this policy launched by the Grenelle environmental agreement and a number of possible improvements.

Contradictions in public policies for biodiversity conservation are inherent in the complexity of the issues concerned and the relationships between stakeholders. How can conflicts of interest be reconciled? How can collective acceptance of conservation goals be improved? Topics for discussion are drawn from the example of policies for diadromous fish.

The French Ecology ministry looks back over several years of public policies for biodiversity conservation. The glass is only half full with mixed results in the field, but significant progress in public debates and some encouraging developments. On the whole, there are still many challenges to be met.

How can a policy be evaluated without measurements? Biodiversity measurements are difficult, but necessary. This difficulty is due essentially to the nature of biodiversity itself (diversity of species and environments, diversity of evaluation methods, diversity of monitoring systems, etc.). The author presents here a few ideas on the topic.

Citizen sciences are undergoing strong growth, a fact demonstrated by the session devoted to the topic at the 3rd French-language meetings on conservation biology (Le reveil du dodo III, 17-19 March 2009 in Montpellier) and the seminar titled Citizen science and biodiversity, held in Montpellier on 22-23 October 2009.
Marion and Frédéric Gosselin, engineer and researcher at Cemagref in Nogent-sur-Vernisson discuss the topic here with Romain Julliard, researcher at the MNHN bird-ringing project and who has managed a number of Vigie-Nature programmes requiring public participation (naturalists and amateurs) to collect the necessary data. The discussion successively addresses the history of citizen sciences, their advantages and limits, focussing on the assessment of biodiversity-conservation policies.

Data on aquatic fauna and flora have been collected for almost two centuries. More or less well conserved, these old data are used in setting up projects for biodiversity conservation and evaluation. To what purpose can the data be put? What precautions must be taken to ensure judicious use?

With the IFN and GIP Ecofor, the Ministerial conference for the protection of European forests (MCPFE) in 2005 was an opportunity to evaluate the national indicators for forest biodiversity and identify priority issues for future work. This article presents the current situation.

Restoration projects are set up for the most threatened species to recreate a former situation considered more satisfactory. But the climate change that has already taken place in certain regions has made it impossible to return to the former situation.

Comparison of two Committees for diadromous-fish management on the Garonne and Seine rivers raises questions on the different types of biodiversity management. What are the strong points, the weak points? What lessons may be drawn for collaborative biodiversity management?

The reintroduction of salmon, wolves and bears has been in the news, but do they represent a true restoration of biodiversity? The authors discuss the advantages and limits to such projects, using as an example the re-introduction of salmon in the Rhine river.

The capacity to determine in advance the behaviour of stakeholders in charge of implementing public policies and to foresee the reactions of the public and consumers impacted by those policies would be a decisive advantage for decision-makers. That was the goal of an experiment to simulate and model the reactions of stakeholders. The initial results are presented here.

Biodiversity landed on the political agenda as the result of a social and scientific process to construct the topic and it now contributes to driving progress in and enhancing the institutional recognition of the various branches of ecology and the social sciences that address biodiversity.
