  • 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

Runsas ja pitkä kevättulva on alueelle tyypillinen piirre; rannoilla kasvaa runsaasti korteikkoja ja saraikkoja. Poosjärvessä on runsaasti eri kokoisia saaria ja luotoja. Saaret ovat suurimmaksi osaksi lehtipuuvaltaisia ja kasvillisuus on lehtomaista. Pienemmät luodot ovat puuttomia lintuluotoja. Rannat ovat luhtaisia. Osaa rantaluhdista ja -metsistä on laidunnettu

4.2 Quality and importance

Poosjärven on harvinaislaatuinen lintuvesialue, sillä järveä ei säännöstellä ja vedenkorkeuden vaihtelu on lähes luonnollinen. Rehevöityminen on ongelma. Järven vedenpintaa on nostettu. Rannoilla on runsaasti loma-asutusta ja muutama vakituinen asunto, jotka kärsivät runsaista kevättulvista. Kaikki tietolomakkeen taulukon 3.2 lajit kuuluvat alueen suojeluperusteisiin ja kaikkien niiden suojelutavoitteena on vähintäänkin alueen merkityksen säilyttäminen osana verkostoa. Lisäksi alueen suojelussa ja hoidossa painotetaan seuraavia tavoitteita: - lajien ja niiden elinympäristöjen tila säilytetään turvaamalla luonnon omien prosessien mukainen kehitys, - lajien ja elinympäristöjen tila säilytetään myös alueen käyttöä ohjaamalla, - lajien ja niiden elinympäristöjen tila säilytetään hoitotoimenpiteillä, - lajien ja niiden elinympäristöjen määrää lisätään elinympäristön ennallistamis- ja hoitotoimenpitein, joilla myös parannetaan elinympäristöjen laatua tai lajin populaation elinvoimaisuutta.
