The Alpine ibex (Capra ibex), also known as the steinbock, bouquetin, or simply ibex, is a species of wild goat that lives in the mountains of the European Alps. It is a sexually dimorphic species: males are larger and carry longer, curved horns than females. Its coat colour is typically brownish grey. Alpine ibex tend to live in steep, rough terrain near the snow line. They are also social, although adult males and females segregate for most of the year, coming together only to mate. Four distinct groups exist; adult male groups, female-offspring groups, groups of young individuals, and mixed-sex groups.
During the breeding season, males fight for access to females, and use their long horns in agonistic behaviour. After being extirpated from most areas by the 19th century, the Alpine ibex was successfully reintroduced to parts of its historical range. All individuals living today descend from the stock in Gran Paradiso National Park in Aosta Valley and Piemonte (Italy), a national park created to help the ibex thrive. The ibex is the emblem of both the Gran Paradiso National Park, and the contiguous Vanoise National Park across the French border. The species is currently listed as of least concern by the IUCN, but went through a population bottleneck of fewer than 100 individuals during its near-extinction event. This has led to very low genetic diversity across populations.
During the Last Glacial Period the species range was reaching as far south as Greece, where it disappeared in the Holocene, after 5,600 BC due to hunting, with the last known remains being found on mountains surrounding Thessaly. The Alpine ibex was, at one point, restricted only to the Gran Paradiso National Park in northern Italy, and the contiguous Maurienne Valley in the French Alps but it was reintroduced to most of the Alps. Reintroductions started in 1906 into Switzerland. Alpine ibex are now found in most or all of the Italian and French alpine ranges, southern Germany, Switzerland and Austria. It has also been introduced to Bulgaria and Slovenia.
An excellent climber, its preferred habitat is the rocky region along the snow line above alpine forests, where it occupies steep, rough terrain at elevations of 1,800 to 3,300 m (5,900 to 10,800 ft). Alpine ibex are typically absent from woodland areas, although adult males in densely populated areas may stay in larch and mixed larch-spruce woodland if no snow has fallen. Males spend the winter in coniferous forests. For most of the year, males and females occupy different habitats.[9] Females rely on steep terrain more so than males. Males use lowland meadows during the spring, which is when snow melts and green grass appears.[10] They then climb to alpine meadows during the summer. When winter arrives, both sexes move to steep, rocky slopes that amass little snow. They prefer slopes of 30–45° and use small caves and overhangs for shelter. Home ranges are highly variable, depending on the availability of resources, and vary in size throughout the year. Figures from 180 to 2,800 ha (0.69 to 10.81 sq mi) have been recorded. Home ranges tend to be largest during summer and autumn, smallest in winter, and intermediate in spring. Female home ranges are usually smaller than those of males. Alpine ibex appear to have a low rate of predation and in Gran Paradiso typically die of age, starvation, or disease.
