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

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)

Other Site Characteristics

A l'exception de l'île de Tatihou constituée de granite carbonifère, le site correspond à une vaste superficie de Domaine Public Maritime où s'opposent des substrats littoraux vaseux et rocheux. Le mode calme de l'anse vaseuse du Cul de Loup contraste avec le mode battu de la Hougue ou encore de l'île de Tatihou. Il accueille bon nombre d'espèces méditerranéo-atlantiques en limite de leur aire de répartition géographique du fait de sa position privilégiée au sein d'un espace de transition entre le bassin Parisien d'affinité nordique d'une part, et le massif Armoricain atlantique d'autre part. La part de DPM représente environ 97,7% de la superficie du site. - Intérêt écologique du site tributaire : * de la préservation de la dynamique des courants et des marées ; * du maintien de la qualité des eaux littorales. - Développement des activités ostréicoles en périphérie et dans le site.

4.2 Quality and importance

Motivations pour la liste des autres espèces importantes de flore et de faune (rubrique 3.3) : - protection réglementaire au niveau national ou régional ; - population remarquable d'espèce patrimoniale. L'habitat "bancs de Zostera", visé par la convention OSPAR, est présent sur ce site.
