The National Park Stilfserjoch has an area
of about 1,350 km² (the part within the South Tyrol project
region is about 520 km²). The area encompases the entire
Ortler-Cevedale massiv and its associated valleys. It covers
altitudinal zones from the valley bottoms to montane and sub-alpine
woodlands and sprawling mountain pastures to the glaciated
regions of the mountian peaks (Ortler 3,905 m). In the north
the National Park borders directly on the Swiss National Park
and in the south on the Adamello Regional Park in Lombardy.
In the Stilfserjoch National Park
the monitoring was coordinated and conducted by Klaus Bliem.
Seven breeding pairs were recorded, but only one pair could
successfully fledge a chick in 2003. Therefore the overall
breeding success was low at 0.29 youngs per pair. All together
29 nest sites were documented, most of them at altitudes between
1,800 und 2,200m.
In 2004 the fieldwork was again coordinated
by Klaus Bliem. The project administration was carried out
by Hanspeter Gunsch. During the 2004 fieldwork an additional
breeding pair was confirmed, therefore the total number of
Golden Eagles increased to 8 breeding pairs. Five of these
pairs successfully raised a young in 2004. The success rate
was therefore more than twice as high as in 2003.
In 2005 only one pair bred successfully
Five of these pairs successfully raised a young in 2004. The
success rate was therefore only 0,13
youngs per pair.
