This weakens tree defence\ncapability and increases damages giving benefits to insect pests and leading to\ntheir increasing frequency and distribution. The European Spruce Bark Beetle (Ips\ntypographus) is causing significant damage to spruce forests both in Europe and\nin Finland, and has ecological, economic and social effects. I. typographus uses\nmainly large, weakened spruces as a reproductive material and benefits from\nwarm conditions. As a key species I. typographus also increases biodiversity. In\nthis thesis, using Geographic Information System (GIS), I studied whether nature\nreserves are distributed closer to or further from the declared I. typographus\ndamage sites between 2012-2022 than randomly selected control sites in Southern\nFinland. Three distance analyses with spruce minimum volumes of\n26/75/120 m3/ha were made. The analyses were repeated in two I. typographus\noccurrence areas, core and invasion front. In addition, the stand volumes were\nanalysed between both target sites and occurrence areas with these three\nminimum spruce volumes to study, whether they could explain the damage. The\naverage distances from the I. typographus damaged sites to the nearest nature\nreserves and control sites were longer than could be presumed, if I. typographus\nwould have dispersed from these sites. However, with different spruce volumes\nthe mutual order between nature reserves and control sites varied as the\ndistances still increased along with the minimum spruce volumes. Because of this,\ntesting focused on the lowest spruce volume. With this spruce volume, the nature\nreserves were further away from the I. typographus damaged sites than the control\nsites. With the stand volumes no such differences between the nature reserves\nand the control sites were observed that could unequivocally explain the\ndamages. Based on this thesis, nature reserves cannot be considered as a general\nrisk to the surrounding economic forests concerning damages by I. typographus.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2024-08-22T05:26:29Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2024-08-22T05:26:29Z (GMT).
