H. Gander et P. Ingold, REACTIONS OF MALE ALPINE CHAMOIS RUPICAPRA-R-RUPICAPPA TO HIKERS, JOGGERS AND MOUNTAINBIKERS, Biological Conservation, 79(1), 1997, pp. 107-109
From June to October 1993 we investigated the responses of male alpine
chamois Rupicapra r. rupicapra to hiking, jogging and mountainbiking
in the Augstmatthorn game reserve (Bernese Oberland, Switzerland). Thi
rty-two experiments were carried out by single persons hiking, jogging
or riding a mountainbike on a trail crossing a pasture preferred by t
he animals for browsing. Median alert and escape distances were 180 an
d 103 m, respectively and did not differ between types of experiment.
Distance fled was influenced both by time of day and by type of experi
ment. Thus, late in the morning the responses of chamois to joggers an
d mountainbikers were slightly stronger than responses to hikers. Afte
r all types of experiment, fewer chamois stayed in the pastures of the
study area than before. Habitat use of the animals was affected by al
l three activities: male chamois left areas near the hiking trail. Cop
