Overview

Distribution

Range Description

This species is endemic to the eastern part of the Great Caucasus along the borders of Russia, Georgia and Azerbaijan between 800 and 4,000 m asl. Its range begins around the headwaters of the Baksan river east of Mount Elbrus (about 43ºN, 43ºE) and stretches for some 600 km eastward along both slopes of the Greater Caucasus to Babadagh mountain (41ºN, 48ºE) (Kuliyev, 1981; Tsalkin, 1955). The distribution is widest (up to 70 km) in Daghestan (Magomedov, Akhmedov and Yarovenko, 2001), being most narrow in North Ossetia (ca. 12 km) (Weinberg, 2002).

Habitat and Ecology

Habitat and Ecology
Eastern tur inhabit elevations between 1,000 and 4,000 m asl. Although the mountains in their range can reach 5,000 m asl, tur seldom rise above 3,500 m asl. They live in forests found up to 2,600 meters, and in subalpine and alpine meadows and rocky talus slopes at higher elevations. Animals avoid thick forests on gentle slopes, but stay readily in open forests growing on steep precipitous slopes. In winters, proportion of animals dwelling below timberline increases (Veinberg, 1984). On average, 34% of eastern tur lived in the forest throughout the year in Georgia (Ekvtimishvili, 1952). Some forest-dwelling populations in Azerbaijan are completely isolated from subalpine and alpine zones (Vereshchagin, 1938; P. Weinberg pers. comm.) In summer, adult males typically inhabit higher altitudes than females and young (Veinberg, 1984). During the region's harsh winters, tur concentrate on sunny slopes; during the summer, animals expand their distribution to slopes of different exposures (Veinberg, 1984; Zalikhanov, 1967; Magomedov, Akhmedov, Yarovenko, 2001). Seasonal migrations rarely exceed 5 km (Veinberg, 1984; Zalikhanov, 1967).

Animals form mixed, adult male-female groups in November, just prior to rut. These disband by mid-January or the beginning of February at the latest, and adult males and females live separately until the next rutting season (Veinberg, 1984). Females give birth predominantly to just one kid (Veinberg, 1984). Proportion of kids may exceed 20% in Azerbaijan (Kuliev, 1981) and Daghestan (Magomedov, Akhmedov, Yarovenko, 2001), but reach only 16,5% in North Ossetia, while yearlings make above 7% there (Veinberg, 1984). Sex ratio favours males in protected populations (Weinberg, 2002). Yearly changes of overall group size depends on the reproductive cycle. Rugged and precipitous terrain reduces group size (Veinberg, 1984; Weinberg, 2002). Mean group size also correlates with population density (Magomedov, Akhmedov, Yarovenko, 2001). Overall mean group size is below 10 in North Ossetia (Veinberg, 1984), but reached ca. 78 in Azerbaijan (Kuliev, 1981). Average population density varies from 0.15 to 17 animals/km² (Weinberg, 2002). Eastern tur consume 256 plant species in Daghestan (Abdurakhamanov, 1977). Eastern tur coexist with chamois (Rupicapra rupicapra) on the northern slope in the Central Caucasus and on the southern slope in the Eastern Caucasus (mainly Azerbaijan), but the latter is much less numerous; in Daghestan and Chechnya, it is sympatric with the wild goat (Capra aegagrus) which dominates in the forest but seldom rises above timberline (Weinberg, 2002).

Justification
Listed as Vulnerable because the population size might not be much great than 10,000 mature individuals (it could be as low as 12,000 mature individuals), and a decline of >10% over the next three generations (estimated at 21 years) is possible. Almost qualifies as threatened under criterion C1.

Population

Population
Following a period of increase between the 1940s and 1960s numbers have since declined. In the late 1960s and early 1970s the total number was estimated to be between 25,000 to 30,000 animals (Kuliyev, 1981; Ravkin, 1975), but by the late 1980s had declined by >30% to between 18,000 and 20,000 head, of which ca. 2,000 occurred in Georgia (Weinberg et al., 1997). Magomedov, Akhmedov and Yarovenko (2001) suggest that there are up to 20,000 tur in Daghestan alone, but this may be optimistic. The latest data suggest that there are no less than 4,000 animals in three Georgian Nature Reserves alone: Kazbegi, Tusheti and Lagodekhi (NACRES, 2006), probably with few tur remaining outside. An estimate of 3,000 tur reported in Kazbegi Nature Reserve might be twice too much (P. Weinberg pers. comm.). In Russia, besides Daghestan, there are about 800 tur in North-Ossetian Nature Reserve (Mallon, Weinberg and Kopaliani, 2007), and about 7,000 animals in Kabardin-Balkaria (Akkiyev and Pkhitikov, 2007) (though the taxonomic status of this latter population remains unclear).

Threats

Threats

Major Threats
Livestock grazing and poaching are the major threats to the eastern tur, combined with the impacts of severe winters. Poaching is probably the most significant cause of the recently observed serious declines. Livestock grazing results in competition for resources, especially with domestic sheep and goats. The species is also impacted by habitat loss and degradation (Weinberg et al., 1997).

Management

Conservation Actions

Conservation Actions
It is included in Category III in the Georgian Red Data Book (1982). Hunting, including hard currency foreign trophy hunting, is forbidden in Georgia, but is permitted under license in Azerbaijan and Russia. This species of tur is found in several Nature Reserves: 5,200 in Kabardin-Balkarian (Russia), 800 in North-Ossetian (Russia), 700 in Lagodekhi (Georgia), and 2,000 in Zakatala (Azerbaijan). Other protected areas with this species include Tushetian and Kazbegi Nature Reserve (Georgia), and Ilisu Nature Reserve with Kakh sanctuary and Ismailly Nature Reserve together with a sanctuary of the same name, and the newly founded Shakhdagh National Park (Azerbaijan). Of these, tur receive effective protection in Kabardin-Balkarian, North-Ossetian, Lagodekhi and Zakatala Nature Reserves. Conservation measures proposed include: 1) create new reserves, particularly in Daghestan on the border with Georgia and Azerbaijan neighboring with Lagodekhi and Zakatala Nature Reserve respectively; 2) strictly enforce protection measures outside the four-month hunting season; if controls are successful and the population responds, then 3) consider the possibility of increasing the annual hunting quota.

East Caucasian tur

The East Caucasian tur (Capra cylindricornis) is a mountain-dwelling goat-antelope found only in the eastern half of the Caucasus Mountains.

East Caucasian turs stand up to 1 metre (39 in) tall at the shoulder and weigh around 60 kilograms (130 lb). They have large but narrow bodies and short legs. They generally have a dark chestnut coat in winter and a lighter chestnut coat in summer. Males have slightly lyre shaped horns which reach around 90 centimetres (35 in) in length while in females they are much smaller (30 centimetres / 12 inches maximum).

East Caucasian turs live in rough mountainous terrain between 800 and 4,000 metres (2,600 and 13,000 ft) above sea level where they eat mainly grasses and leaves and are preyed upon by wolves and lynxes. Females live in herds of around ten individuals, while males are solitary.

Contents

Mating and young

Breeding occurs from late November to early January, with births taking place in May and June. Giving them a gestation period of only around 150 days (about six months). Young turs are extremely agile, being able to scamper about steep slopes after only a day of life. They generally start sampling grasses after on months, but continue to suckle for 2-4 months.

Feeding and migration

During the warm months, feeding occurs at intervals throughout the late afternoon, night, and morning, with the hottest hours of the day being spent resting in sheltered places. In winter, herds may remain in open pastures throughout the day, alternately grazing and resting. Daily movements may cover 15 to 20 kilometres (9.3 to 12 mi).

There is a seasonal migration covering a vertical distance of 1,500 to 2,000 metres (4,900 to 6,600 ft), with an upward thrust in May and a retreat downwards in October. The solitary adult males generally inhabit higher altitudes than groups of females and their young, descending to join them in the breeding season. During this time, vigorous competitions arise as they vie for mating rights. In protected areas, the density of animals varies between 5/km² and 16/km².
