Popis: Permanent grassland (PG) covers 35% of the agricultural area in the EU-28. Across Europe, PG exists in many contrasting managed or unmanaged environments where it contributes to feed supply, biodiversity, carbon sequestration, aesthetic value, recreation, clean water and prevention of soil loss. The delivery of these PG ecosystem services is under threat by land use change, climate change and sub-optimal management. We carried out a survey among experts to assess the threats within their countries. Respondents described the main PG-types, together with their areas, and assessed to what extent a particular PG-type is threatened by intensification, land use change, climate change or nitrogen (N) depositions. Threats were scored on a three-point scale: no, small or great. Replies were received from 11 countries (CH, CZ, DE, ES, HU, IT, ME, NL, PL, SE, UK), representing the main biogeographic zones in Europe. The dataset contained 83 PG- types on a total area of 25 Mha. Abandonment, heat and drought stress and conversion to temporary grassland were considered as the largest threats, each considered as a great threat on PG-types covering 8 to 9 Mha (~35%). The second largest group comprised N depositions, conversion to arable land and intensification, each as a great threat on PG-types covering 4 to 5 Mha (~20%).
