- 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
Le lit majeur de la Sarre repose sur une marne imperméable du Keuper recouverte de dépôts alluvionnaires gréseux récents provenant des Vosges.
L'Albe prend elle sa source sur des plateaux calcaires.
Les couches les plus profondes contiennent du sel qui a fait l'objet d'une exploitation jusque vers le milieu de ce siècle (secteur de Salzbronn).
L'ensemble des habitats remarquables présents sur le site est sous l'étroite dépendance de la combinaison eau/pratiques agricoles.
Les vallées doivent conserver leur caractère inondable ; il est souhaitable d'éviter les perturbations du niveau hydrologique et de la qualité de la nappe.
Une agriculture "traditionnelle" extensive avec prairie de fauche et apports d'intrants limités est la seule capable de conserver la valeur patrimoniale du site. Tant l'abandon des pratiques agricoles que leur intensification conduirait à la disparition des habitats remarquables.
La présence occasionnelle du Courlis cendré et du Râle des genêts nécessite le maintien ou le retour à des fauches tardives ainsi que la conservation d'un ensemble prairial cohérent. |
4.2 Quality and importance
L'intérêt du site est d'être composé d'une mosaïque d'habitats.
La vallée de l'Isch se caractérise également par ses prairies à sanguisorbe qui abritent l'Azuré des paluds.
On trouve également 2 noyaux de population de l'Agrion de Mercure, l'un dans le marais de Léning, l'autre sur la Zelle.
Enfin, les marais de Léning et de Veckersviller hébergent quelques specimens de Vertigo angustior. |
