One of these species is the moor frog, which is classified under the EU Habitats Directive Appendix IV (a). These species are strictly protected also outside nature conservation areas. The species has declined in Central Europe, but is still common in Northern Europe. According to the EU Commission, the reproductive and resting places should be determined by the local population used by the local population. Many complex environmental factors affect the size and use of animals\u2019 ecological network. Estimating the effect of these factors on animal movements and use of habitat is often very challenging. Radio tracking provides powerful tool for studying movements and habits of animals. In this study we investigated with the radio tracking method moor frogs (Rana arvalis) habitat requirements and use of the habitat in a changed environment in a peat production area. The aim of the study was to get information on moor frog\u2019s summer habitat and distance to the spawning site, and to draw conclusions about the quality and size of summer habitat. The acknowledge collected from study makes possible more specific accurate threat assessments of specie and help to direct the conservation inputs to where the need is greatest. The research population was selected based on the spawning survey of a relatively large occurrence of moor frogs. Displaying males could be encountered in completely vegetation-free ditches, but the spawn was always let down on places where there was even little vegetation. The juveniles moved mostly in the mid-summer when the movement of adult individuals was focused on early and late summer. Most moor frogs were encountered in a fire pond between peatlands in the middle of the study site, where they were caught and released for radio tracking research during spawning. Movement varied 341 meters between individuals of the same population. In the autumn moor frogs burrowed into the ground for winter. The peat production area seems to be suitable as a place of occurrence if certain requirements relevant to the habitat are met. Moor frogs occurred in small, watery and vegetated ponds and ditches and their surroundings. Based on the study, it would appear that the living environment requirements of the moor frog may be more modest than was previously assumed. The moor frog population of the research area seemed vital but the quality and connectivity of the habitats can be further improved and taken into greater consideration when designing peat production measures.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Janne Ruuth (jajuruut) on 2018-01-15 14:03:49.281962.
