- 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
Tratto medio del Fiume Tevere comprendente l'asta fluviale ed i due bacini artificiali di Corbara e di Alviano. Dal punto di vista vegetazionale l'area si caratterizza per la presenza di vegetazione idrofitica (3150), cenosi a Chara sp. (3140), elofitica e ripariale (92A0, 91E0) nonchè di boschi a Quercus ilex sui versanti soleggiati e di Quercus cerris su quelli ombrosi (91H0) e di Castanea sativa (9260) in alcuni limitati settori. Diffusi nell'area ci sono arbusteti a prevalenza di Juniperus communis (5210), pascoli della classe Festuca-Brometalia (6210) e formazioni termo-mediterranee ad Ampelodesmos maurutanicus, lungo la gola del Forello sono inoltre presenti cenosi rupicole a Buxus sempervirens (5110). |
4.2 Quality and importance
Area di grandissima rilevanza naturalistica ed ambientale, sia per l'ingente quantità di fitocenosi legate agli ambienti umidi, sia per l'importanza faunistica rappresentata da questa zona che, posta lungo l'asta del Tevere, si trova su di uno dei maggiori assi migratori italiani. Attualmente il Lago di Alviano rappresenta una delle più importanti zone di sosta di numerosissima fauna migratoria legata agli ambienti umidi. Tra le specie faunistiche si ricordano anche: Triturus vulgaris meridionalis, specie vulnerabile; Martesmartes, specie molto rara; Mustela putorius, specie vulnerabile e rara, leuciscus cephalus, popolazione autoctona; Accipiter nisus, specie rara; Buteo buteo, poco comune; Cettia cetti, stenotopa ed indicatrice delle qualità ambientali della vegetazione ripariale; Falco tinnunculus, specie poco comune. |
