  • 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

Other Site Characteristics

This is a forested area with large parts of flat-rock pine forest on outcrop of Precambrian bedrock. In shallow valleys there are thin layers of till. Unlike several other sits of similar type this site have rather wide fissure-valleys with clay and fen peat. In these areas alder, birch and Norwegian spruce dominates the forest. It is wet with lots of small springs. A few small parts of the valleys have been arable fields and are now young planted mono-culture of spruce.

4.2 Quality and importance

Large parts of the site show little or no signs of modern forestry. It is rich in dead wood, i.e. logs. The large areas of old natural forest on clay is very unusual and waste areas affected by spring water is even more exclusive. The long continuity of moist micro-climate in forest with continuous presence of dead wood maintains a exclusive flora of bryophytes and wood-inhabiting fungi. Within the site there is unfortunately several cleared areas and artificial spruce monocultures, mainly on former arable fields.
