Is an operational index an efficient way to assess naturalness along land transport infrastructures

The identification and assessment of biodiversity holders landscapes, in relation to land transport infrastructure and rights of way, represent a strong demand from managers operators dense urban environment. In the object of our study, the infrastructure concerned correspond to roads, highways, railways, tram, road or river water per channel, or gas line right-of-power lines. Are considered potentially biodiversity rich landscapes that are not occupied directly and strictly by the elements of the infrastructure network but which correspond to it to the extent that they constitute operator to land territory integrated spaces manager.

To improve the recognition of the ecological functioning of transport infrastructure and adapt the choice of way management and associated tools for the conservation and the development of a lasting nature and quality, we developed methodology sheets to better understand how there is a range of landscapes and habitats appropriately constituent patches, islets, continuums or frames including ecological biodiversity within these infrastructures and build on comparative ecological dynamics encountered.

The methodology sheets are intended to inform the reader and user of the operational sheets and contribute to the knowledge of some potentially promising biodiversity dynamics on rights of the infrastructure. Therefore there are soil functioning of embryos for the development of a habitat favorable to the establishment of spontaneous living beings or domesticated, we consider that there is a space in nature.

In this way, we sought to define a multitude of patches corresponding to space objects, combining a portion of transportation infrastructure space and a form of land use.
