The primary goal of this research is to design an effective ground survey method for monitoring the East Caucasian Tur (Capra cylindricornis) in the Kazbegi district, while simultaneously investigating threats and proposing conservation strategies through field observations and local expert consultation.
1.3.2 Habitat
Tur favour subalpine open forests and alpine meadows between 1’000 – 4’000 m., in or close to steep and rocky slopes. Concerning altitude, extreme observations are recorded from 800 m. for lowers, up to 4’600 m (Dinnik, nd) for the highest altitudes. Gavashelishvili (2004a) has shown that its highest probability of occurrence is at elevation 3’008.4 m., and is negatively correlated with rainfall.
Males prefer higher, gentler slopes and open habitats while females use lower, steeper, and open to sparsely forested areas. Tur favour southern slopes in the winter (93% of sightings) and northern ones in the summer (53.5% - Fig. 5). Avoiding snow as much as possible, turs are victim of avalanches during severe winters. Massives deaths due to avalanches are recorded in some areas, killing for example 370 Turs in one area, 367 in another area. As mentioned by Couturier, (1962b), Tur distribution is influenced by the presence and activity of man.
If turs in general have a rather avoiding attitude toward man, they can nevertheless charge when they are aculeated. Couturier (1962a) wrote that the presence of man obliges turs to go either up to the highest summits at the alpine and nival floor, or down to the forests at the subalpine floor.
1. Introduction: Provides the legal, biogeographical, and biological background of the East Caucasian Tur, establishing the research objectives and the problem of population decline.
2. Methods: Details the field study area and the specific methodologies employed, including sample counts via telescope, aerial surveys, and the use of questionnaires for gathering stakeholder input.
3. Results: Presents the findings regarding population density, Tur habitat utilization, camera trap data, and analysis of movement patterns based on local surveys.
4. Discussion: Synthesizes the results to suggest future management and monitoring strategies, including potential translocations and the application of new technology for wildlife conservation.

The thesis focuses on the conservation and monitoring of the East Caucasian Tur (Capra cylindricornis) in the Kazbegi region of Georgia, examining its population density, habitat, and the threats it faces.
The field research was conducted in two primary ranges: the Kuro range and the Chkere gorges, located on either side of the Tergi River.
The main goal is to establish an effective, non-intrusive ground survey method to estimate Tur density and to gather information on conservation opportunities to improve the status of the species.
The study employed a combination of direct ground observations using telescopes and binoculars, camera trapping, aerial survey data analysis, and qualitative survey interviews with local conservation stakeholders.
The study found a net population density of approximately 4.7 individuals per square kilometer in the sampled areas, while noting the negative impact of human activities like overgrazing and illegal hunting on Tur behavior and distribution.
The work is characterized by terms such as Caucasian tur, population monitoring, mountain habitat, conservation, and GIS-based analysis.
Turs generally exhibit an avoidance strategy, often moving to higher, more inaccessible summits or deeper into forests when disturbed by human activity.
The questionnaire survey helps bridge the gap between scientific observation and indigenous knowledge, identifying local perspectives on threats like illegal hunting and proposing potential management solutions.
