  • 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)

4.2 Quality and importance

The following data refer to the period 1993-1997 (data in paragraph 3.2a-b refer te period 1999-2003). For Oudegaasterbrekken: Species meeting the 1% threshold (non-breeding): Pink-footed Goose Anser brachyrhynchus (39,3%), Barnacle Goose Branta leucopsis (3,8%). For Fluessen en omgeving: Species meeting the 1% threshold (non-breeding): Barnacle Goose Branta leucopsis (3,4%). This site is a complex of lakes and adjacent wet grasslands, important for waterfowl. This is an important roost for geese Anser from surrounding feeding areas. Site largely overlaps with IBA061and IBA62 (IBA2000).
