- PF: for the habitat types that can have a non-priority as well as a priority form (6210, 7130, 9430) enter "X" in the column PF to indicate the priority form.
- NP: in case that a habitat type no longer exists in the site enter: x (optional)
- Cover: decimal values can be entered
- Caves: for habitat types 8310, 8330 (caves) enter the number of caves if estimated surface is not available.
- Data quality: G = 'Good' (e.g. based on surveys); M = 'Moderate' (e.g. based on partial data with some extrapolation); P = 'Poor' (e.g. rough estimation)
3.2 Species referred to in Article 4 of Directive 2009/147/EC and listed in Annex II of Directive 92/43/EEC and site evaluation for them
- Group: A = Amphibians, B = Birds, F = Fish, I = Invertebrates, M = Mammals, P = Plants, R = Reptiles
- S: in case that the data on species are sensitive and therefore have to be blocked for any public access enter: yes
- NP: in case that a species is no longer present in the site enter: x (optional)
- Type: p = permanent, r = reproducing, c = concentration, w = wintering (for plant and non-migratory species use permanent)
- Unit: i = individuals, p = pairs or other units according to the Standard list of population units and codes in accordance with Article 12 and 17 reporting (see reference portal)
- Abundance categories (Cat.): C = common, R = rare, V = very rare, P = present - to fill if data are deficient (DD) or in addition to population size information
- Data quality: G = 'Good' (e.g. based on surveys); M = 'Moderate' (e.g. based on partial data with some extrapolation); P = 'Poor' (e.g. rough estimation); VP = 'Very poor' (use this category only, if not even a rough estimation of the population size can be made, in this case the fields for population size can remain empty, but the field "Abundance categories" has to be filled in)
3.3 Other important species of flora and fauna (optional)
- Group: A = Amphibians, B = Birds, F = Fish, Fu = Fungi, I = Invertebrates, L = Lichens, M = Mammals, P = Plants, R = Reptiles
- CODE: for Birds, Annex IV and V species the code as provided in the reference portal should be used in addition to the scientific name
- S: in case that the data on species are sensitive and therefore have to be blocked for any public access enter: yes
- NP: in case that a species is no longer present in the site enter: x (optional)
- Unit: i = individuals, p = pairs or other units according to the standard list of population units and codes in accordance with Article 12 and 17 reporting, (see reference portal)
- Cat.: Abundance categories: C = common, R = rare, V = very rare, P = present
- Motivation categories: IV, V: Annex Species (Habitats Directive), A: National Red List data; B: Endemics; C: International Conventions; D: other reasons

Other Site Characteristics
Grand ensemble regroupant une vaste zone humide arrière-littorale provenant du comblement du golfe de Machecoul et de Challans après la transgression flandrienne ; baie marine renfermant des vasières à forte productivité, île et cordons dunaires. Une partie du littoral endigué au cours des derniers siècles a donné naissance à des systèmes de polders et de marais salants. Grand intérêt paysager de l'ensemble du site.
En se basant sur les laisses des plus hautes mers indiquées sur les cartes IGN, le taux de surface marine du site est de 30%.
Menaces sur la conservation du fait de la déprise agricole (difficultés économiques des systèmes d'élevage bovin extensifs) : des opérations locales agri-environnement sont en cours pour ralentir ce phénomène, limité cependant par la médiocre qualité des sols qui n'offrent que peu de possibilités d'intensification (à l'exception des élevages hors-sol). La forte pression touristique sur le littoral induit divers aménagements (routes, campings...) et une pression urbaine importante, particulièrement sur l'île de Noirmoutier et la frange littorale. |
4.2 Quality and importance
L'ensemble de la zone présente un état de conservation très intéressant.
L'intérêt mycologique est également à signaler.
Présence de l'habitat OSPAR 'Bancs de Zostera' et ponctuellement de l'habitat OSPAR 'Récifs de Sabellaria spinosa'. |
