Other Site Characteristics

Porvoon keskustan itäpuolella sijaitseva pienialainen vanhan metsän alue, joka rajautuu lännessä Veckjärveen, idässä Tungträsketiin ja etelässä suureen voimalinjaan. Metsä on tyypiltään lehtomaista kangasta. Pohja on paikoin soistunut. Puusto on varttunutta ja varttuvaa tiheää kuusikkoa, jossa on sekapuuna koivua ja hieman mäntyä.Tungträsketin rantavyöhykkeellä on kapea tervaleppää ja hieskoivua kasvava vyöhyke. Haaparyhmiä on paikoin. Alueella on tasaisesti maapuita ja kuolleita puita. Vanhoja lahoja kantoja on merkkinä vanhoista hakkuista.

4.2 Quality and importance

Alue on varsin pienikokoinen, mutta Uudellamaalla vanhan metsän kohteet ovat niin harvinaisia, että jokainen alue on erittäin tärkeä. Metsän lajistoa on tutkittu vain vähän, lähinnä kääpälajistoa on kartoitettu. Se on potentiaalinen vanhan metsän lajiston esiintymispaikka, joskin pieni koko lienee johtanut lajiston köyhtymiseen. Rajautuminen kahdelta suunnalta järveen monipuolistaa aluetta. Vanhan metsän lajiston kannalta uhkana on jäädä pieneksi saarekkeeksi talousmetsien keskelle. Alueen suojelutavoite: Kaikki tietolomakkeen taulukossa 3.1 mainitut luontotyypit kuuluvat alueen suojeluperusteisiin ja kaikkien niiden suojeluperusteena on vähintäänkin alueen merkittävyyden 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
