To maintain the high biodiversity and preserve the conservation value of semi-natural grasslands, management like grazing or mowing is necessary. Given the limited resources available for management, and few remaining areas, the best management method and intensity should be used. However, the evaluation and comparison of effects of different management intensities on a larger scale is often challenging, as most studies have a limited scope (e.g. only investigating effects in one grassland or for one type of organism). In view of this, we used meta-analysis methods to explore effects of different mowing intensities on biodiversity on a European scale, to reach more robust conclusions. We included studies examining effects of annual mowing compared to both more and less frequent mowing, e.g. twice a year or every other year, on European grassland flora and fauna. Our results suggest that mowing more frequently than once per year has a more positive effect on grassland biodiversity, especially in more productive grasslands. However, differences in effects between frequencies were small, suggesting that mowing more seldom could be a viable management option. This meta-analysis is an example of how ecological knowledge can be compiled to contribute to evidence-based conservation policy and more cost-effective management. ...

Threatened grassland butterflies as indicators of microclimatic niches along an elevational gradient – Implications for conservation in times of climate change Fartmannn, Thomas; Stuhldreher, Gregor (Open Science Centre, University of Jyväskylä, 2018)Among the factors that determine habitat quality for butterflies, an adequate microclimate has crucial importance, especially for the less mobile immature stages. Therefore, stenotopic butterflies are precise indicators ...
Systematic targeting of management actions as a tool to enhance conservation of traditional rural biotopes Raatikainen, Kaisa; Mussaari, Maija; Raatikainen, Katja M.; Halme, Panu (Elsevier, 2017)Traditional rural biotopes (TRBs), which are biologically and culturally valuable habitats maintained by low-intensity grazing and mowing, are a core element of biodiversity in Europe. During the last decades, TRBs have ...
Raatikainen, Kaisa J. (University of Jyväskylä, 2018)This research focuses on conservation of traditional rural biotopes, which are biodiverse meadows and wood-pastures that are dependent on management through grazing or mowing. These low-intensity management actions ...
Climate change and habitat management implications for a declining grassland songbird in the North American Great Plains Arcilla, Nicola; Glass, Alex (Open Science Centre, University of Jyväskylä, 2018)Accelerating climate change is affecting species worldwide, and is expected to have impacts on more than half of North American bird species. Some of the most rapidly declining birds in continental North America include ...
Kasari, Liis; Esko, Annely; Prangel, Elisabeth; Hernández-Agramonte, Ignacio M.; Helm, Aveliina (Open Science Centre, University of Jyväskylä, 2018)In the beginning of 20th century, 1/3 of mainland area of Estonia – 18 000 km2 – was covered by semi-natural grasslands. Since then, similarly to all other regions in Europe, changes in land-use resulted in abandonment and ...
