Résumé : |
One postulated that reversing the loss of biodiversity requires a quasi-religious transformation of the way contemporary cultures view the value of human life and the intrinsic values of organic diversity. Even if that transformation were to occur today, we would be faced with a cruel reality : maintaining viable examples of every natural community, including the myriad of species they support, is the fundamental mechanism for conserving biodiversity, from genes and species to ecosystems, have distributions but they have not been mapped at scales useful for developing a national biodiversity conservation and management strategy.
Centuries of scientific collectors have deposited tens of millions of specimens in the world’s museums and herbaria. These form the foundation of our knowledge of species distributions, yet many areas and taxa remain poorly sampled. While not a substitute for traditional biological surveys, we feel that gap analysis can provide a preliminary, landscape-scale assessment of the distribution of both species and ecosystem diversity that can be used to guide future field research and to provide a spatial framework for a preliminary national biodiversity conservation strategy. The gap analysis approach to biodiversity survays holds promise for the rapid development of information on the distribution of several indicators of biodiversity in areas of the world that have been less well-sampled.
We identify four steps in gap analysis : (1)identify and classify biodiversity, (2) locate areas managed primarly for biodiversity, (3) identify biodiversity that is un or underrepresented in those managed areas and (4) set priorities for conservation action. While these steps remain essential to gap analysis, the distribution of the vegetation cover and species, gathered as a precursor to analysis, has considerable application to natural resource inventory and monitoring in and of itself.
