  • 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

De Vlakte van de Raan wordt begrensd door de -20 NAP lijn aan de zeezijde, de Speciale Berschermingszone (SBZ) Voordelta, de SBZ Westerschelde en aan de zuidkant door de grens met België.Op geologische schaal is er sprake van grootschalige bodembewegingen in het gebied, die enerzijds bestaan uit een langzame daling van de Noordzeebodem en anderzijds uit een geleidelijke stijging van het Massief van Brabant (De Mulder et al., 2003) waarop een serie van paleocene, pleistocene en holocene sedimenten zijn afgezet (Le Bot et al., 2003, 2005). De samenstelling van de bodemsedimenten in het Westerscheldemondingsgebied is zeer heterogeen. Zowel zandige sedimenten als slib komen voor (Du Four et al. 2006).

4.2 Quality and importance

De Vlakte van de Raan is van belang voor vissen, benthos en vogels. Kenmerkende soorten van de Klaverbank zijn: Aonides paucibranchiata, Chone duneri, Glycera lapidum, Glycera alba, Laonice bahusiensis, Pistella lornensis, Typosyllis cornuta, het bulldozerkreeftje Urothoe marina, de Gewone zeeappel (Psammechinus miliaris) en de tweekleppige Dosinia exoleta (Van Moorsel 2003).
