Habitat requirements of endangered species in a former coppice of high conservation value

摘要: Transformation of coppices to high forests has caused fundamental changes in site conditions and a decline many species across Central Europe. Nevertheless, some formerly coppiced still harbour number the declining have become biodiversity hotspots changing landscape. We focused on best-preserved remnant grazed subcontinental oak forest Czech Republic – Dubrava near town Hodonin. To improve our understanding ecology species, we studied local habitat requirements vascular plants most endangered at national level. recorded vegetation composition sampled important variables plots with largest populations additional placed randomly all major habitats. demonstrated that sites highly uneven distribution ecological space their is often similar open-canopy forests. Within this habitat, are concentrated places light availability soil pH. Light-demanding characteristic best indicators these sites, while broadly distributed shade-tolerant nutrient-demanding avoid them. These results support view occurrence legacy long history traditional management kept canopies open. now threatened by ongoing successional changes. Therefore, active conservation measures recommended, including opening up canopies, early thinning young stands, control expansive invasive understorey grazing or mowing.
