RARE AND ENDANGERED SPECIES OF TERRESTRIAL MOLLUSK IN WESTERN TIEN SHAN

Аннотация

This article is about rare and endangered species of terrestrial mollusk in Western Tien Shan and for two of them nature conservation status is evaluated as – CR (that is on the verge of complete disappearance), for five species-VU:R (vulnerable really rare) and for a species-NT(close to threat, narrowly areal endemic species). Destruction and transformation of habitats, deforestation of shrubby vegetation, cattle overgrazing, active construction, afforestation in primarily treeless steppe and rocky places, rock mining, including export of separate stones and excessive recreation are the main causes of becoming rare and disappearance of the species.
