The Goshawk indicates forest biodiversity as many threatened species are present in sites that the Goshawk uses for nesting. Therefore, it is important to study forest characteristics typical for Goshawk\u2019s nesting sites in managed forests in order to be able to locate and to target conservation efforts to sites with potentially high biodiversity. In this study, data from National Forest Inventory (NFI) were analyzed with maximum entropy modelling of species\u2019 distributions using the MaxEnt program to identify environmental characteristics typical of the Goshawk\u2019s nest sites, and to locate forests likely suitable for Goshawk nesting within the region of Central Finland. In addition, nest site selection of the Goshawk was studied by detecting differences in habitats between the surroundings of Goshawk\u2019s nest sites and randomly selected forested locations with Random Forest classifier using forest patch inventories and other geographic data from multiple sources. According to my results, the Goshawk prefers forests with a minimum of 150 m3/ha of spruce mixed with some deciduous trees as a nesting habitat. Of the land area of the region of Central Finland, about 8 to 9 % was designated excellent or suitable for Goshawk nesting.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2019-06-20T05:56:24Z\r\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2019-06-20T05:56:24Z (GMT).
