Potential linear connecting areas of the watercourse network — Metropolitan City of Florence

Identification of the quality of potential linear connecting areas of the watercourse network. There are four types of river connections identified: — continuous potential trait (fluvial): stretch of a watercourse of less than 500 m length passing through medium or high natural areas (woods, meadows or pastures) but for which water quality data and information on wildlife populations are very scarce or absent; — potential trait to be retrained (influvial): stretch of a waterway that runs through medium-anthropised areas (agricultural areas, small urban centres) and has potential characteristics of a corridor (contiguities with better quality, real or potential) but for which data on water quality and information on wildlife populations are very scarce or absent; — potentially interrupted (fluvial) tract: stretch of a watercourse that crosses highly man-made areas (urban centres) or that crosses averagely man-made areas (agricultural areas, small urban centres) but not adjacent to better quality, real or potential, for which there is a lack of data on water quality and information on wildlife populations is very scarce or absent; — interrupted (fluvial) tract: section of a heavily polluted or artificial (channel) watercourse.
