L'IQE : un indicateur de biodiversité multi-usages pour les sites aménagés ou à aménager

There are currently no standardized assessment tools to define the ecological quality of industrial sites and landfills sites. The Natural Heritage Service of the National Museum of Natural History has developed an Ecological Quality Index (Indicateur de Qualite Ecologique, IQE). This is based on a six-day inventory at the scale of species and ecosystems i) on the diversity of natural habitats and birds, ii) on wildlife and natural heritage value of a site and iii) an index of ecological functionality. Inventories conducted on 29 sites over a four-year period, were compared with published literature and expert knowledge. This approach allowed the modification or validation of each parameter, including the scoring system of these two indices. A shorter version of this index, based on a one-day inventory, the Ecological Potentiality Index (Indicateur de Potentialite Ecologique, IPE) has also been developed, using a similar structure
