Other Site Characteristics

Petäjäjärvi on Ylöjärvellä sijaitseva monipuolinen luonnonsuojelualue. Sen kapea pohjoisosa, Lehtivehmas, on lähinnä vanhaa kuusikkoa, jossa vaihtelevat kuivahkot harjanteet ja kosteat korpinotkelmat. Etelään mentäessä alue laajenee länteen käsittäen mm. Petäjäharjun ja Liinalamminevan räme- ja avosuoalueen. Vanhaa kuusivaltaista metsää on Iso Kaitajärven itä- ja pohjoispuolella sekä länsipuolella suoalueiden väliin jäävinä metsäharjanteina. Alueella on kaksi pientä suolampea ja humuspitoinen Iso Kaitajärvi.

4.2 Quality and importance

Alue on erittäin tärkeä eriasteista kuollutta ja lahoavaa kuusta suosiville lajeille, mitä osoittaa mm. aarniometsiä indikoivien jäkälälajien runsaus (13 lajia, pääasiassa kuusen epifyyttejä). Hyönteislajistossa on runsaasti vanhan metsän lajeja. Alueella paljon tuulenkaatoja. Alue on arvokas luontotyyppiensä monipuolisuuden vuoksi. Alueella on jonkin verran suo-ojia, mutta ainakin osa niistä on jo umpeutumassa. Suojelutavoitteen määrittely: 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 - alueella vallitseva luontotyyppien ja lajien sekä niiden elinympäristöjen tila säilytetään hoitotoimenpiteillä
