Mets\u00e4ekosysteemiss\u00e4 hakkuut\u00e4hde voi vaikuttaa esimerkiksi puiden kasvuun ja kasvien monimuotoisuuteen. Aiemmat tutkimustulokset puiden kasvusta ovat olleet ristiriitaisia. T\u00e4m\u00e4n tutkimuksen tarkoituksena oli saada lis\u00e4\u00e4 tietoa hakkuut\u00e4hteiden vaikutuksista kuusien (Picea abies) ja rauduskoivujen (Betula pendula) kasvuun reilun 20 vuoden j\u00e4lkeen avohakkuista.

After timber harvesting, there will be logging residues. It is possible to leave logging residues to the forest or collect residues for bioenergy. According to previous studies logging residue can affect for example the tree and plant growth but influence on the growth of the trees is inconsistent. The aim of this research was to gather information about how logging residues affect the growth of silver birch (Betula pendula) and Norway spruce (Picea abies) in 20-year-old forests. We also examined how logging residue affects other plants \u2013 especially mosses (Bryophyta) - than trees. We also studied how tree species affects the vegetation. Research was conducted in Soidinm\u00e4ki at three areas with silver birches and Norway spruces. Areas contained different amount of logging residues. Tree growth was estimated by measuring tree trunk diameter at breast height. Plants species composition and frequency were measured with a quadrat. Moreover, plant species outside of the quadrat but in the research area were listed. We found that logging residue did not increase growth of the trees nor change diversity of vegetation. However, logging residue lowered the growth of the silver birch. Additionally, we found that tree species had species-specific effect on vegetation. Spruce increased and silver birch decreased the coverage of mosses. In conclusion, there is need for more studies about the subject, because the results were inconsistent, and the experimental design was ambiguous in terms of block effects.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2023-06-22T08:09:08Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2023-06-22T08:09:08Z (GMT).
