Suomessa soita on ojitettu esimerkiksi mets\u00e4- ja maataloutta varten, ja ojituksen my\u00f6t\u00e4 soiden lajiston monimuotoisuus on heikentynyt huomattavasti. Soiden ennallistamisella pyrit\u00e4\u00e4n palauttamaan soiden vesitalous ja lajisto mahdollisimman l\u00e4helle luonnontilaisen kaltaista. Ennallistamisen taustalla on Unelmien kentt\u00e4 -hypoteesi (\u201dField of Dreams\u201d -hypoteesi), jonka mukaan lajit palautuvat luontaiseen elinymp\u00e4rist\u00f6\u00f6ns\u00e4, kun elinymp\u00e4rist\u00f6n olosuhteet palautuvat niille suotuisiksi.

In Finland, mires have been drained for forestry and agriculture, for instance. Because of the drainage, biodiversity of mires has decreased remarkably. The aim of mire restoration is to restore the hydrology and species of the mires close to the natural state. Restoration is based on \u201cField of Dreams\u201d hypothesis, according to that the species will return to their natural habitat when the conditions of the habitat are favorable for them. Ground beetles, spiders and ants have been used often in studies concerning the state of the environment. In my Master\u2019s thesis I studied long-term effects of restoration to the number of individuals of ground beetles, spiders and ants, and number of species and species composition of ground beetles after 17\u201320 years from restoration. The aim of the research was to find out if the restoration had been successful based on if the number of individuals of invertebrates had returned to a level like the natural state. Additionally, the results were also based on if the typical ground beetles of mires had started to return after restoration. Four mires in Central Finland were used as research sites, and every mire had three treatments: natural, drained, and restored treatment. I collected invertebrate samples by pitfall traps. The number of ground beetle individuals differed between restored and drained treatments, but the number of species was similar between the treatments. Species composition was similar between restored and natural treatment, but drained treatment had different species than either of them. There was no difference in the number of ants or spiders between restored and drained treatment. Based on this research, the long-term effects of mire restoration had positive effects on ground beetles. The effects of restoration on spiders or ants were not so clear. Species identification for spiders and ants would be needed for more precise results. In conclusion, the returning of species comprehensively would need more time after restoration even though invertebrate species have returned to some extent in a few decades.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2025-06-11T05:38:07Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2025-06-11T05:38:07Z (GMT).
