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
Ensemble comprenant la Loire fluviale "sauvage" et une partie de sa vallée alluviale (principalement le val endigué). La variété des milieux est bien représentative d'un fonctionnement relativement peu perturbé du fleuve. Intérêt paysager et culturel de cette partie du val de Loire.
Déséquilibres morphologiques et hydrauliques (restauration en cours, Plan Loire). Vigilance nécessaire sur la pression urbaine et touristique. Banalisation des milieux souvent aux dépens des prairies naturelles. Progression des espèces exotiques envahissantes.
4.2 Quality and importance
L'intérêt majeur du site réside dans les espaces périphériques au fleuve lui-même, en particulier dans les "boires" et autres milieux aquatiques à riche végétation d'hydrophytes, les prairies mésophiles à hygrophiles, les boisements ripariaux et le bocage à Frène oxyphille. Les grêves exondées en période d'étiage présentent également un intérêt pour certaines espèces végétales.
Enfin, l'axe du fleuve lui-même est essentiel pour les populations de poissons migrateurs, encore assez bien représentées.
