- 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 site est localisé sur 2 domaines biogéographiques: 1% pour le domaine atlantique et 99% pour le domaine continental.
Ce massif est le plus occidental des systèmes forestiers de type ardennais et l'unique exemple de ces potentialités médioeuropéennes submontagnardes en Picardie. L'ensemble est particulièrement exemplaire et représentatif avec une remarquable diversité de situations géomorphologiques, géologiques et édaphiques favorables aux gradients d'hydromorphie et de pH.
Les habitats forestiers les plus typiques sont : les forêts rivulaires des petits ruisselets torrentueux associés à des zoocoenoses aquatiques oligo-mésotrophes exceptionnelles en Picardie ; les boulaies à sphaignes des plateaux inclinés tourbeux hydromorphes riches en Viola palustris. Deux unités lacustres de grand intérêt écologique présentent de façon exemplaire les dernières séquences de ceintures amphibies mésotrophes acidiclines du nord de la France.
Ce massif est très original par ses paysages de montagne et ses biotopes (notamment tout le cortège lié aux ruisselets d'eau vive). Il se continue au nord de la Picardie sur le territoire Nord/Pas-de-Calais.
L'enrésinement massif de certaines parties de la forêt et la dégradation sensible des eaux de l'Oise sont les principales ombres à la bonne conservation des qualités biologiques du massif qui s'est nettement appauvri, sur le plan floristique au moins, depuis le début du siècle, mais dont les potentialités restent relativement préservées. On exclura les drainages qui tentent à assécher progressivement tout le plateau hydromorphe de la partie nord-est du massif et bouleverse les caractéristiques hydrauliques et les bilans hydriques des habitats. La qualité du cours de l'Oise reflète les dégradations subies en amont dans la partie belge et agricole de son bassin. |
4.2 Quality and importance
| Les intérêts spécifiques, intégrant ces particularités montagnardes et ardennaises aux nombreux biotopes forestiers et intraforestiers, sont élevés au niveau :
-floristique : nombreuses plantes en limite occidentale ou orientale de leur aire, diversité importante des cortèges oligotrophes à mésotrophes, 13 espèces protégées, nombreuses plantes menacées ou rares (Luzula luzuloides, L. sylvatica, Vaccinium myrtillus, Helleborus viridies subsp. Occidentalis)
-invertébrés aquatiques et terrestres : Damier de la Succise (un individu observé en 2006), Perles, Odonates avec 2 libellules exceptionnelles pour le nord de la France, lépidoptères submontagnards,...
-batrachologique : Urodèles
-ichtyologique : Lamproie de Planer, Chabot commun, Truite fario (souche sauvage)
-mammalogique : Chat sauvage
-ornithologique : avifaune forestière nicheuse rare et en limite d'aire comptant 8 espèces menacées au plan national dont le Cincle plongeur, la Gélinotte des bois, la Bécasse des bois, de nombreux rapaces,...). Le site est inventorié en ZICO. |
