Etenkin lahopuun m\u00e4\u00e4r\u00e4 metsiss\u00e4 on romahtanut, jolloin useiden lahopuusta riippuvaisten lajien, kuten k\u00e4\u00e4pien, m\u00e4\u00e4r\u00e4 on v\u00e4hentynyt huomattavasti. T\u00e4m\u00e4n vuoksi entisi\u00e4 talousmetsi\u00e4 on alettu ennallistaa muun muassa poltoin ja lahopuulis\u00e4yksin, jotta metsien monimuotoisuus, dynamiikka ja rakenne palautuisivat nopeammin luonnonmets\u00e4n kaltaisiksi. Tutkimuksen tavoitteena oli selvitt\u00e4\u00e4, voiko ennallistamisella lahopuulis\u00e4yksin lis\u00e4t\u00e4 k\u00e4\u00e4pien runsautta ja lajim\u00e4\u00e4r\u00e4\u00e4 mets\u00e4ss\u00e4, jossa luonnon lahopuuta ei juurikaan ole.

Ennallistamistoimenpiteen\u00e4 puita oli kaadettu ja kaulattu kuoleviksi pystypuiksi noin 15 vuotta sitten 30 ennallistamisseurantakohteella. K\u00e4\u00e4pien runsautta ja lajim\u00e4\u00e4r\u00e4\u00e4 tutkittiin vertaamalla kahta k\u00e4sittely\u00e4; koealoja, joissa lahopuulis\u00e4yksi\u00e4 oli tehty, ja kontrollialoja, joissa lis\u00e4yksi\u00e4 ei ollut tehty. Lis\u00e4ksi tutkittiin k\u00e4\u00e4p\u00e4yhteis\u00f6jen eroja k\u00e4sittelyjen ja puulajin v\u00e4lill\u00e4. Tulosten mukaan \nennallistamistoimenpitein\u00e4 tehdyt lahopuulis\u00e4ykset edesauttoivat k\u00e4\u00e4pien \nrunsastumista koealoilla.

K\u00e4\u00e4p\u00e4yhteis\u00f6t erosivat niin k\u00e4sittelyjen kuin my\u00f6s puulajin osalta toisistaan, mik\u00e4 viittaa siihen, ett\u00e4 lahopuulis\u00e4ykset paransivat k\u00e4\u00e4p\u00e4yhteis\u00f6jen monimuotoisuutta koealoilla.
