| Description | The Keeled Plump Bush-cricket (Isophya costata) is included in the EU – Habitats directive. It reaches its northwestern-most range limit in Austria, in the Weinviertel, where its largest population occurs in the Natura 2000 site “Weinviertler Klippen-zone”. The first occurrences were discovered there in 2000 (Buschberg) and 2003 (Michelberg), and targeted surveys in suitable habitats eventually took place in the entire Natura 2000 area in 2017 and 2018. No further records were found outside the known area of occurrence. The population on the Buschberg does not appear endan-gered at the moment, provided that current grassland management practices and the late cutting date (ideally after 1 July) are maintained. |
