• 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

Species					Population in the site						Site assessment
G	Code	Scientific Name	S	NP	T	Size		Unit	Cat.	D.qual.	A|B|C|D	A|B|C
						Min	Max				Pop.	Con.	Iso.	Glo.
P	1386	Buxbaumia viridis			p				P	DD	C	A	C	B
I	1013	Vertigo geyeri			p				C	DD	C	A	C	A

• 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)

Other Site Characteristics

The area consists of several habitats, broad-leafed deciduous forest, pastures and calcareous fens on the waterfront to the Baltic archipelago. It has a long history of human small-scale impact.

4.2 Quality and importance

The importance is linked to the agricultural landscape, the decidous forest and the wetlands. The mix of the agricultural landscape and the decidous forest has created species-rich habitats. Many redlisted species are recorded within the reserve. The lichen flora contains a few very exceptional species. The area is popular for the public out-door life.
