- 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)

- 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
En périphérie de l'agglomération stéphanoise, sur les contreforts du massif du Pilat, ce site est constitué de quatre entités de gestion.
Ce site comprend aussi d'anciens terrils miniers.
- Risques de modification des pratiques agricoles (déprises, intensification…) qui pourraient entraîner la disparition des pelouses et des prairies naturelles de fauche.
- Risque d'évolution des landes vers des boisements.
- Site dans un secteur possédant une pression d'urbanisation importante (en périphérie de l'agglomération stéphanoise) régulée par les documents d'urbanisme.
- Risque de reconversion des hêtraies et forêts alluviales, ou au contraire d'un abandon de la gestion de ces milieux par les propriétaires. |
4.2 Quality and importance
Ce site, situé au sud du département de la Loire, a été principalement retenu pour la présence de landes, notamment des landes à Ajonc nain (Ulex minor). On y retrouve également des forêts alluviales dans les fonds de vallons et des hêtraies sur les versants. Certaines hêtraies ont été classées Espaces Naturels Sensibles par le Conseil Général de la Loire.
Les rebords supérieurs des vallons sont utilisés par l'agriculture avec la présence de pelouses sèches et de prairies de fauches.
Par ailleurs la présence d'espèces en limite de répartition (Ajonc nain, Pavot du Pays de Galle…) témoigne de la légère influence atlantique dont bénéficie le site.
Le site Natura 2000 est menacé par :
Les modification des pratiques agricoles (déprises, intensification…) qui pourraient entraîner la disparition des pelouses et des prairies naturelles de fauche ;
L'évolution des landes vers des boisements ;
La pression d'urbanisation importante (en périphérie de l'agglomération stéphanoise) régulée par les documents d'urbanisme ;
La reconversion des hêtraies et forêts alluviales, ou au contraire d'un abandon de la gestion de ces milieux par les propriétaires. |
