Have a look on our islands...

The definition of a small island is an adjustment of several parameters, both physical, biological, socio-economic and yet sensitive.

Here is the definition proposed by the PIM Initiative:

"An island is a mass of land hosting at least one vascular plant (or other species of terrestrial or marine heritage importance), clearly identified and separated from another emerging land (more than 5 meters away and with at least 50 cm depth in the channel or remaining detached at low tide), including the surrounding marine fringe (up to a bathymetry of -50 meters and within one nautical mile around the island). In the framework of the PIM Initiative, an island is qualified as "small" below 1000 hectares of land surface, corresponding to a size at which islets are mostly beginning to become inhabited and subject to more complex anthropogenic impacts with a very significant influence on biodiversity and landscape.Are not considered as an island : rocks of a few square meters with no differentiated stakes from the closest island, islands connected to the continent by a bridge, and islands located in wetlands".
