  • NP: in case that a habitat type no longer exists in the site enter: x (optional)
  • Cover: decimal values can be entered
  • Caves: for habitat types 8310, 8330 (caves) enter the number of caves if estimated surface is not available.
  • 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)

Other Site Characteristics

Siirasoja on mutkittelevan syväreunaisen raviinilaakson pohjalla, johon etelästä yhtyy soilta laskevia sivuojia. Paikoin jyrkillä rinteillä on vaatimattomia metsäkurjenpolvi-käenkaali-oravanmarjatyypin lehtoja. Siirasojan varsilla on reheviä mesiangervoluhtia ja laakeammilla paikoilla luhtanevoja ja luhtaisia nevakorpia. Kaltevilla reunoilla on tihkupintaisia - lähteisiä, runsasruohoisia korpia. Yhdessä sivuhaarassa on pienellä alalla tervaleppäkorpea (suurimpien tervaleppien halkaisija 50 cm). Lähdesoilla kasvaa mm. lettorikkoa ja muita Kainuussa uhanalaisia ja harvinaisia lajeja.

4.2 Quality and importance

Kaikki tietolomakkeen taulukoissa 3.1 ja 3.2 mainitut luontotyypit ja lajit (lukuun ottamatta edustavuudeltaan luokkaan D luokiteltuja luontotyyppejä ja populaation merkittävyyden osalta luokkaan D luokiteltuja lajeja) 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, - luontotyypin tai lajin elinympäristön laatua tai lajin populaation elinvoimaisuutta parannetaan ennallistamis- ja hoitotoimenpitein.
