- 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)

Other Site Characteristics
Habitatområdet er karakteriseret ved de mange små holme, Store Stenholm, Lille Stenholm, Spirholm og Langholm, der til sammen er på ca. 100 ha og som indbyrdes er forbundet af stenede tanger. Området er af marin oprindelse og er i geologisk sammenhæng dannet ved udvaskning af Yngre Yoldialer - en proces, der begyndte for 4 - 5000 år siden, da Læsø dukkede op af havet. Stenrevet Per Nilen´s udstrækning er ikke systematisk opmålt, men der er gennemført dykkerundersøgelser i udvalgte punkter. På de undersøgte stationer forekommer tætte stenforekomster fra 6 og ned til 10-11 meters dybde. På 11 meters dybde tiltager andelen af sand og grus. Revet er helt domineret af en tæt flerlaget algevegetation. Faunaen er ikke markant og indgår ikke som strukturerende element på revet. |
4.2 Quality and importance
Området indgår i det nationale overvågningsprogram for marin bundvegetation. Området er karakteristisk ved sin tætte flerlagede algevegetation. Stenrevet er af væsentlig biologisk betydning p.g.a. den tætte samling af endog meget store sten dækkende samtlige zoner i den marinbotaniske zonering. |
