- 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 se compose de deux entités géographiques différentes ; la partie nord comprend d'une part les grands massifs forestiers, notamment la partie Wallonne de la Forêt de Soignes et des zones boisées du Parc Solvay, d'autre part le fond de vallée de l'Argentine et ses zones humides ; tandis que la partie sud correspond au fond e vallée de la Lasne et englobe des milieux ouverts de grand intérêt comme la lande de Rixensart, la réserve du Carpu et la zone humide du Ru Milhoux. |
4.2 Quality and importance
Grandes surfaces de hêtraies et chênaies acidophiles atlantiques, que l'on retrouve largement en Forêt de Soignes et dans les domaines forestiers environnants et qui constituent l'habitat du pic mar et du pic noir. En fonction des niveaux de richesse et d'humidité des sols, on retrouve également d'autres habitats forestiers, dont des forêts alluviales et marécageuses. Les fonds de vallée humides abritent également quantité d'autres habitats, qu'il s'agisse d'étangs, de mégaphorbiaies, de roselières... avec un cortège d'espèces associées à ces milieux, comme la sarcelle d'hiver, le martin-pêcheur, le grand butor ou le maillot de Desmolin. Il est encore important de souligner la présence d'habitats de grand intérêt dans la vallée de la Lasne : des landes sèches, une nardaie et une prairie à molinie. Ces 2 derniers milieux sont rarissimes en zone atlantique, ce qui confère au site des vallées de l'Argentine et de la Lasne une importance majeure. |
