negative impact on chamois numbers [24] .<br />

Overall, both our analysis and the general<br />

literature suggest a beneficial effect of protection,<br />

conservation management measures such as the<br />

reduction of competition from other ungulates,<br />

and adequate hunt<strong>in</strong>g quota. On the other hand,<br />

over-exploitation and disease are associated with<br />

population decreases.<br />

areas, for example <strong>in</strong> the National Park of Ecr<strong>in</strong>s<br />

<strong>in</strong> the French Alps, the National Park of Ordes <strong>in</strong><br />

the Pyrenees and Grand Paradiso <strong>in</strong> Italy [17] . In<br />

addition, sarcoptic mange, a contagious <strong>in</strong>festation<br />

of the burrow<strong>in</strong>g mite [2] , which causes<br />

scabies <strong>in</strong> the Northern chamois and was first<br />

described <strong>in</strong> Bavaria and Styria at the beg<strong>in</strong>n<strong>in</strong>g<br />

of the 19 th century [2] , is believed to be the one<br />

disease to have had the most severe impact on<br />

populations, thus present<strong>in</strong>g a threat to conservation<br />

[2] . It causes high mortality of up to 80%<br />

and is now most widespread <strong>in</strong> Austria, Slovenia<br />

Although the Northern chamois has been able<br />

to recover both <strong>in</strong> terms of distribution and<br />

abundance, the species is still subject to a variety<br />

of threats throughout its range. These <strong>in</strong>clude<br />

(for example through tourism) [9, 11] , competition<br />

with livestock and <strong>in</strong>troduced species (only<br />

applicable to vulnerable subspecies exclud<strong>in</strong>g<br />

R. r. rupicapra), habitat loss (mostly applicable<br />

to vulnerable subspecies) [9] , hybridisation [9] ,<br />

disease [1, 9] , and stochastic demographic and<br />

environmental events <strong>in</strong> subspecies with small<br />

populations [9] . The comb<strong>in</strong>ation of threats is<br />

different for each of the European subspecies<br />
