Other Site Characteristics

Pomarkussa sijaitseva Isoneva kuuluu Rannikko-Suomen kermikeidasvyöhykkeen Etelä-Suomen kermikeitaisiin. Alue koostuu lähinnä kolmesta laajasta keidassuoalueesta. Korvet, ombrotrofiset rämeet ja nevat ovat vallitsevina. Yleisimpiä suotyyppejä ovat lyhytkorsinevarämeet ja lyhytkorsinevat. Korpia on vähän, samoin luhtia ja vedenviipymiä. Allikoiden ja muutaman ojan lisäksi ainoat vesialueet ovat kaksi lampea. Vähälukuisten kivennäismaasaarekkeiden metsiä on käsitelty 1980-luvulle saakka, joitain myöhemminkin.

4.2 Quality and importance

Isoneva on alueellisesti ajatellen poikkeuksellisen laaja luonnontilaisena säilynyt keidassuo. Se on edustava konsentrinen kermikeidas, jonka itäosa on paremmin kehittynyt. Isoneva on laajalla alueella tärkeimpiä lintusoita, tärkeä muuttolintujen levähdysalue. Alueella vallitseva luontotyyppien ja lajien sekä niiden elinympäristöjen tila säilytetään turvaamalla luonnon omien prosessien mukainen kehitys. Osalla aluetta luontotyypin tai lajin elinympäristön laatua tai lajin populaation elinvoimaisuutta parannetaan ennallistamis- ja hoitotoimenpitein. Kaikki tietolomakkeen taulukossa 3.1 mainitut luontotyypit kuuluvat alueen suojeluperusteisiin ja kaikkien näiden osalta suojelutavoitteena on vähintäänkin alueen merkityksen säilyttäminen.
