The canyon's unique climate has been preserved since ancient times. Here, along the Sharyn River, grows the last relic of Kazakhstan (a local endemic), the Sogdian Ash, which appeared on Earth approximately 25 million years ago. It is a member of the olive family (Oleaceae), one of the representatives of the moist broadleaf forests that managed to survive the Ice Age.
About 1,500 plant species grow on the slopes and floor of the gorge, 17 of which are listed in the Red Book of Kazakhstan. Within the canyon, you can find thickets of willow, barberry, saxaul, acacia, ephedra, tamarisk, and chingil. Furthermore, the valley is home to a grove of glaucous-leaved poplar (Turanga glabra). This name refers to a type of poplar native primarily to Central Asia.
In 1964, the Sogdian ash's habitat was designated the "Charyn Ash Forest Dacha" natural monument. A chain of ancient burial mounds runs along the grove.
The gorge is home to 62 species of mammals. Here you can encounter foxes, goitered gazelles, Siberian ibex, hares, jerboas, ground squirrels, ermines, stone martens, and Pallas's cats. The Charyn Canyon is home to 25 species of reptiles and three species of amphibians, and ornithologists have counted over 100 species of birds on its slopes.
