Area which is part of the scientific inventory developed under an international program of Birdlife International to identify the most favorable areas for the conservation of wild birds.
Area designated under the 1979 Birds Directive 79/409 / EEC. Areas of importance for the conservation of birds (IBAs) are sites that have been identified as important for certain bird species (breeding areas, seabirds). wintering or migration relay areas) during the scientific inventory program launched by the NGO Birdlife International. They don't have a particular legal status. The most suitable sites for the conservation of the most endangered birds are classified totally or partially in Special Protection Areas (SPAs). The latter, associated with the Special Areas of Conservation constitute the network of Natura 2000 sites.
Areas established pursuant to EEC Directive 79/409 on the protection of birds and their habitats. They have been delineated by the network of French ornithologists on the basis of the criteria proposed in a methodological note. After validation, they are designated to be designated Special Protection Areas (SPAs).
Natural (spring) or artificial access (drilling, drain, well, etc) to groundwater. Each water point has a national code (BSS code) and is located by geographic coordinates through a projection system. It is also defined by the following additional pieces of information: a name or label, an altitude, an address (locality), a location map.
The term ‘habitat’ refers to an inseparable complex comprising: - fauna, including species that carry out all or part of their various life activities within the area in question; - vegetation (herbaceous, shrubby and arboreal); - a site-specific environment (climatic conditions, soils and parent material, and their physico-chemical properties). A habitat is not limited to vegetation alone. However, due to its integrative nature (synthesising the environmental conditions and functioning of the system), vegetation is considered a good indicator and helps to define the habitat. (source: Rameau et al., 1998).
Environment defined by specific abiotic and biotic factors in which a species lives at any stage of its life cycle. A natural habitat is distinguished by geographic, abiotic and biotic entirely natural or semi-natural.
Surface area feeding a watercourse or a body of water. The catchment area is defined as the area of water collecting up to an outlet: it is limited by a border within which all waters flow on the surface and underground to this outlet. Its boundaries are the watersheds (water divide - US).
Movement of an oceanic water body.
Natural environment marked by the temporary or permanent presence of water, hosting a specific flora and fauna. Examples include a marsh, bog, pond, pond, pond, estuary, etc.
An area where water, whether fresh, salty or brackish, is the main factor controlling the natural environment and the associated animal and plant life. Wetlands are fed by stream flow and/or rising water tables and are shaped by the alternation of high and low water levels. Examples include streams, peat bogs, ponds, ponds, ponds, banks, floodplains, salt meadows, mudflats, coastal marshes, estuaries. These areas are transition spaces between land and water (they are ecotones). The vegetation present has a marked hygrophilic character (which absorbs water). Like all these types of particular spaces, it has a strong biological potential (specific fauna and flora) and have a role in regulating flow and improving water quality.
There are several regulatory definitions of the term "Wetland" depending on the text:
