3.1 Habitat types present on the site and assessment for them

3210  info      1.5  0.00 
  • 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)

4.1 General site character

Habitat class % Cover
N06100.00

Total Habitat Cover

Other Site Characteristics

Ån rinner genom ett aktivt jordbrukslandskap med förekomster av trädridåerframförallt uppströms. Förekomsten av tjockskalig målarmussla är god på vissa platser.

4.2 Quality and importance

Vedaån ingår i svärtaåns avrinningsområde och rinner från sjön Likstammen (Natura 2000-område) till sjön Svarvaren. Ån är ca 6 km lång och är känd för sin goda vattenkvalité. Ett flertal inventeringar har visat på en mycket hög artdiversitet beträffande bottenfauna med flera mycket ovanliga arter som kräver en hög vattenkvalité. Under 2005 har även den hotade tjockskaliga målarmusslan påträffats med både äldre och yngre individersom visar på en fungerande förökning i åsystemet.
