Ennallistamistoimilla, kuten lahopuun m\u00e4\u00e4r\u00e4n lis\u00e4\u00e4misell\u00e4 tai kulotuksella, pyrit\u00e4\u00e4n j\u00e4ljittelem\u00e4\u00e4n mets\u00e4n luontaisia h\u00e4iri\u00f6it\u00e4, kuten tuulenkaatoja tai mets\u00e4paloja. Intensiivisen mets\u00e4nhoidon piiriss\u00e4 olevaan tasaik\u00e4iseen ja v\u00e4h\u00e4lajiseen mets\u00e4\u00e4n ihmisavusteinen h\u00e4iri\u00f6, kuten lahopuun lis\u00e4\u00e4minen ja/tai kulotus, luo monimuotoisempaa rakennetta ja uutta kasvutilaa. T\u00e4m\u00e4n tutkimuksen tavoitteena oli testata maakiit\u00e4j\u00e4isten vasteita ennallistamistoimiin, kun ennallistamisesta oli kulunut seitsem\u00e4n vuotta eli hieman pidempi aika kuin useimmissa mets\u00e4n ennallistamista koskevissa tutkimuksissa. Tutkimuksen kohteena toimivat kuoppapyydyksin pyydystetyt maakiit\u00e4j\u00e4is-heimon kovakuoriaiset (Coleoptera: Carabidae), koska ne ovat ekologisesti hyvin tunnettu ryhm\u00e4 ja niiden tiedet\u00e4\u00e4n vastaavan herk\u00e4sti mets\u00e4nhoitotoimenpiteiden aiheuttamiin elinymp\u00e4rist\u00f6n muutoksiin. Tutkin ennallistamisen vaikutuksia maakiit\u00e4j\u00e4isten yhteis\u00f6rakenteen vaihteluun tutkimusaloilla, joita oli kulotettu, harvennettu ja j\u00e4tetty erilaiset m\u00e4\u00e4r\u00e4t maapuuta. Lis\u00e4ksi huomioin tutkimusalojen sis\u00e4ll\u00e4 olleen kosteusgradientin. T\u00e4m\u00e4n tutkimuksen perusteella maakiit\u00e4j\u00e4islajisto vaikutti selvinneen ennallistamistoimenpiteist\u00e4 ts. h\u00e4iri\u00f6ist\u00e4 kohtalaisen hyvin. Tarkempaa tarkastelua varten jaoin lajiston mets\u00e4n latvuskerroksen sulkeutuneisuuden mukaan mets\u00e4-, avomaa- ja generalistilajeihin. Mets\u00e4lajisto oli s\u00e4ilynyt parhaiten alojen kosteilla ruuduilla, mutta avomaa- ja generalistilajisto n\u00e4yttiv\u00e4t yleisesti hy\u00f6tyneen h\u00e4iri\u00f6ist\u00e4. Kulolajistoa ei l\u00f6ytynyt, joten edes voimakkaimmin palaneet alat eiv\u00e4t tarjonneet niille sopivia resursseja. Luontaisiin h\u00e4iri\u00f6ihin sopeutuneet lajit voivat hy\u00f6ty\u00e4 mutta metsien herkimm\u00e4t lajit k\u00e4rsi\u00e4 ennallistamisesta, joten mets\u00e4n historia, rakenne ja lajisto t\u00e4ytyy tuntea ennen ennallistamistoimiin ryhtymist\u00e4.
