Other Site Characteristics

Kolkanaukko ja Rantalanlahti ovat matalia merenlahtia. Lahtia ympäröivät rantalehdot, ruovikot ja merenrantaniityt. Järvikaislakasvustot ovat runsaita ja rantapuusto on pääasiassa tervaleppää. Alueella tavataan tammivaltaisia lehtoja. Lehdot vaihtelevat kuivasta hyvin rehevään. Alue on linnuston levähdyspaikka.

4.2 Quality and importance

Kasvillisuus on alueella edustava. Kolkanaukon ranta-alueet ovat loivia, joten lehtomaista ja niittykasvillisuutta esiintyy. Rantalanlahti on geomorfologialtaan jyrkempi. Kohdealue on valtakunnallisesti arvokas lintuvesi. Ruovikkolajeja on paljon. Suojelutavoitteen määrittely Kaikki tietolomakkeen taulukoissa 3.2 mainitut lajit (lukuun ottamatta populaation merkittävyyden osalta luokkaan D luokiteltuja lajeja) kuuluvat alueen suojeluperusteisiin ja kaikkien niiden suojelutavoitteena on vähintäänkin alueen merkityksen säilyttäminen osana verkostoa. Tämän lisäksi alueen suojelussa painotetaan seuraavia tavoitteita: - Alueella vallitseva luontotyyppien ja lajien sekä niiden elinympäristöjen tila säilytetään turvaamalla luonnon omien prosessien mukainen kehitys ja ohjaamalla käyttöä. - Luontotyyppien ja lajien elinympäristön laatua tai lajien populaatiotioiden määrää lisätään ennallistamis- ja hoitotoimenpitein.
