- 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
| Rivière Ellé et ses principaux affluents, des sources jusqu'à Quimperlé, ainsi que bas-marais et tourbières des têtes de bassin-versant.
Le cours moyen offre une très grande diversité de paysages riverains: côteaux abrupts avec affleurements schisteux, landes sèches, boisements mixtes anciens, éboulis périglaciaires; prairies à hautes herbes, prairies pâturées, boisements tourbeux; Localement, des chaos rocheux parsèment le lit de la rivière, en situation très encaissée, ombragée, à forte hygrométrie permanente.
La préservation de la qualité et de la diversité des habitats et des espèces des milieux tourbeux et des bas-marais périphériques peut être compromise par l'abandon des pratiques agricoles extensives (fauche, pâturage), des modifications du régime et de la qualité des eaux alimentant ces espaces (pollution agricole, exploitation de carrière de kaolin). La qualité générale du cours d'eau dépend également dans une large mesure de la capacité à maîtriser les pratiques agricoles sur les bassins-versants.
Il importe par ailleurs de maintenir les variations saisonnières du niveau d'eau de l'étang de Priziac et de limiter les éventuels apports sédimentaires exogènes (pollution) ou endogènes (mise en suspension des sédiments par des pratiques nautiques) afin de conserver au plan d'eau son caractère oligotrophe et d'éviter tout accroissement de la turbidité et atterrissement des berges. |
4.2 Quality and importance
| Ensemble fluvial de très grande qualité caractérisé par les groupements à renoncules (annexe I) et accueillant une importante population reproductrice de Saumons atlantiques (annexe II) ainsi qu'une population sédentaire et reproductrice de Loutre d'Europe (annexe II) sur l'ensemble du bassin en amont de Quimperlé. La Mulette perlière (annexe II) est présente sur l'Ellé et au moins deux de ses affluents l'Aër et le Naïc.
Les bas-marais des têtes de bassin-versant, en particulier les marais de Plouray, sont remarquables par leur étendue, la diversité phytocénotique, et la composition du cortège floristique et faunistique associés: bas-marais, landes mésophiles (annexe I) et landes humides tourbeuses à sphaignes (habitat prioritaire), notamment, avec plusieurs stations de la Sphaigne de la Pylaie, espèce présente uniquement en Bretagne et en Espagne (Galice et Asturies) pour l'Europe.
L'étang de Priziac, zone humide complexe, accueille en particulier une des rares stations françaises de la Lobélie de Dortmann (protection nationale), espèce inféodée aux étangs oligotrophes à eaux claires (annexe I) à fond sableux, se découvrant à l'étiage, et à ce titre indicatrice de la qualité du milieux. |
