- 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)
3.3 Other important species of flora and fauna (optional)
- Group: A = Amphibians, B = Birds, F = Fish, Fu = Fungi, I = Invertebrates, L = Lichens, M = Mammals, P = Plants, R = Reptiles
- CODE: for Birds, Annex IV and V species the code as provided in the reference portal should be used in addition to the scientific name
- 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)
- 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)
- Cat.: Abundance categories: C = common, R = rare, V = very rare, P = present
- Motivation categories: IV, V: Annex Species (Habitats Directive), A: National Red List data; B: Endemics; C: International Conventions; D: other reasons

Other Site Characteristics
Alue on valtakunnallisesti merkittävä hyvin tyypillinen ja edustava keidassuo. Suon keskusta on märkä ja maisemallisesti kaunis. Upottavaa nevaa, kermit ja kuljut vuorottelevat. Alueen lounaisosassa on pieni lampi. Alueella on myös useita isoja allikoita ja vähän ruoppakuljuja. Suon etelä-osassa on erittäin jyrkkä reunalaide, jonka alapuolella on rehevää kasvillisuutta.
Suon pohjoisosaa luonnehtivat laajat rahkanevapinnat sekä lyhytkortiset nevat; kankaiden reunoilla on myös saranevaa. Suon laidoilla esiintyy sararämettä sekä isovarpuista ja lyhytkortista rämettä. Myös rahkaräme on yleinen. Pari sarakorpikuviotakin esiintyy alueella. Alueen reunaosissa on monin paikoin luonnonmukaisen kaltaisia varttuneita havupuuvaltaisia metsiä, joissa esiintyy liito-oravia ja harvinaisena haavanhyytelöjäkälää.
Linnusto on keidassuolle tyypillinen, suolla pesii paikallisesti runsaasti vesilintuja ja kahlaajia.
Suon laitoja on osittain ojitettu, arvokkain osa on kuitenkin luonnontilassa. |
4.2 Quality and importance
Edustava, lähes luonnontilainen, laakiomainen konsentrinen kermikeidas. Monipuolinen linnusto.
Suon laiteita on jonkin verran ojitettu ja ennallistamistoimet ovat paikoin tarpeen.
Kaikki tietolomakkeen taulukoissa 3.1 ja 3.2 mainitut luontotyypit ja lajit kuuluvat alueen suojeluperusteisiin ja kaikkien niiden suojelutavoitteena on vähintäänkin alueen merkityksen säilyttäminen osana verkostoa.
Lisäksi alueen suojelussa ja hoidossa painotetaan seuraavia tavoitteita:
• alueella vallitseva luontotyyppien ja lajien sekä niiden elinympäristöjen tila säilytetään turvaamalla luonnon omien prosessien mukainen kehitys,
• luontotyypin tai lajin elinympäristön laatua tai lajin populaation elinvoimaisuutta parannetaan ennallistamis- ja hoitotoimenpitei.n |
