  • 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

Kohde muodostuu kolmesta alueesta: 1. Riihikallio; vanha lehtipuuvaltainen, osittain lehtomainen rinnemetsä, lahopuita melko runsaasti. 2. Pilkanmäet; pinnanmuodostukseltaan vaihteleva (korkeusero yli 25 m) ja puustoltaan vaihteleva, pääosin vanhaa ja luonnontilaista. Lehtipuiden osuus paikoin yli 50 %, lahopuita runsaasti. 3. Ojavallanmäki; runsaasti vanhaa lehtipuustoa sekä laho- ja kelopuustoa, poikkeuksellisen runsaasti iäkästä haapaa.

4.2 Quality and importance

Tärkeä kokonaisuus vanhaa ja lahoavaa lehtipuustoa hyödyntävälle eliöstölle. Erittäin uhanalaisen lintulajin viimeisiä elinalueita Suomessa. Uhkana jäädä saarekkeiksi talousmetsien keskelle, jolloin ainakin linnustollinen merkitys saattaa heikentyä. Kaikki tietolomakkeen taulukossa 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. Luontotyypin tai lajin elinympäristön laatua tai lajin populaation elinvoimaisuutta parannetaan ennallistamis- ja hoitotoimenpitein.
