In Styria (Austria) the highest located windpark within Europe was built between 1,800 and 1,900 m a.s.l. at a lek site of black grouse in 2002. After five years monitoring data show a strong decline of the local black grouse population. Collisions of the birds with the towers are recorded, disturbance because of wind park maintenance, infrastructure and tourism are difficult to evaluate. On another mountain ridge in Styria with two windparks and a ski lift the same drastic population decline was registered. Within the province of Styria between 30 and 40 locations for windparks were discussed from different points of view (technology, energy, ecology). Locations for windpower plants in alpine regions overlap with lek sites of black grouse to a very high percentage.
