The Hohe Tauern National Park covers an
area of over 1,800 km² . The Park includes areas of the
Austrian Provinces of Carinthia, Salzburg and Tyrol. The Hohe
Tauern National Park, together with the bordering Nature Park
Rieserferner-Ahrn (Autonomous Province of Bozen) and also
the bordering Zillertal Alps Nature Park (Tyrol), form the
largest spatially integrated nature reserve of the Alps. The
Hohe Tauern National Park embraces a range of alpine habitats
from montane woodlands to the highest peaks of the Eastern
Alps (Grossglockner 3,798 m).
In the Hohe Tauern National Park the fieldwork
was done by Norbert Winding, Michael Knollseisen, Robert Lindner
and Christian Sichler. They were supported by staff of the
national park and by local hunters. Altogether 162 eyries
were documented, most of them at an altitude between 1,500-1,900
m, with the lowest eyrie at 1,100 m and the highest at 2,100
m.
All together a total of 33 breeding pairs
of Golden Eagles was recorded. Two more pairs seemed likely,
but could not be confirmed in 2003. For 26 pairs the breeding
success was documented. The success rate in 2003 was 0.54
fledged eagles per pair. All together 150 Horste Eagle nests
were recorded and documented in detail. Only 8 nests were
built in trees all the others were situated in cliffs.
In 2004 additional pairs of Golden Eagles
were confirmed. This was mainly in areas where last years
data did not reveal clear information about the breeding status
of eagles. The population of Golden Eagles in the “Hohe
Tauern” ares can therefore be estimated between 38-40
pairs. The breeding success of 28 pairs was monitored in detail.
These pairs raised a total of 22 young eagles. This results
in a breeding success rate of 0.79 fledglings per pair –
a very high average value. One of the reasons for this high
success rate was that two pairs managed to raise 2 young eagles.
In 2005 again two new breeding pairs could
be confirmed. Therfore the total known population in the National
Park Hohe Tauern now comprises 42 to 43 pairs, with one pair
occupying a territory right on the border of the National
Park. Hence the National Park Hohe Tauern is home to roughly
12 % of the estimated total population of Golden Eagles in
Austria.
