The Impacts of Contrasting Grazing Management on Biodiversity in Upland Calcerous Grasslands

Ashley Lyons


Calcareous grassland is one of the most species rich and diverse habitats in Europe. However, following post 1950s agricultural intensification they have faced decline and degradation, with losses of up to 75% in some places. Today there are an estimated 595000 ha of calcareous grassland in the Natura 2000 network, with 35500 ha occurring in Great Britain.

In recent years conservation organisations have altered grazing practices in an attempt to conserve the characteristic vegetation of these internationally important habitats. However, there has been little consideration of the effects of these contrasting grazing practices on invertebrate communities or their relationship with plants.

This project examined the impacts of contrasting grazing practices on spiders, carabid beetles and plants in upland calcareous grasslands. Many of the results of this project provided the first evidence of effects of contrasting grazing management in upland calcareous grassland. This evidence will form the basis of the first management recommendations for upland calcareous grasslands to include invertebrates, and not plants, as the main focus.

Working closely with conservation agencies, evidence from this project will form the basis of the first management recommendations for upland calcareous grasslands to include invertebrates as the main focus.
