The lake area is an internationally recognized Ramsar site, important for its ornithofauna, and a tourist wildlife reserve.

[3][4][5] The Kalkankale Formation, consisting of old sandstone, mudstone and claystone dating back to early Pliocene period, underlies wide areas at Lake Kuyucuk and the surrounding landscape, and forms the flat and low-sloped terrain of the region.

The wetland flora are free-floating aquatic plants from the duckweed family (Lemna), common reed (Phragmites australis) and rushes (Juncus) while the steppe flora are shrubs and herbs (Astragalus, Onobrychis), vetches (Vicia), daisy (Artemisia), common dandelion (Taraxacum officinale) and alsike clover (Trifolium hybridum).

An artificial islet on the lake was formed in 2009 to provide a safe breeding place for bird species and to help protect them from predators.

[8] The Ramsar site harbors bird species such as ruddy shelduck (Tadorna ferruginea), the globally endangered white-headed duck (Oxyura leucocephala), vulnerable red-breasted goose (Branta ruficollis), vulnerable velvet scoter (Melanitta fusca), western marsh harrier (Circus aeruginosus), common crane (Grus grus), black-winged stilt (Himantopus himantopus), Eurasian coot (Fulica atra), black-necked grebe (Podiceps nigricollis), common starling (Sturnus vulgaris) and greylag goose (Anser anser).

[6] Other notable fauna found around the lake are the mammal species red fox (Vulpes vulpes), Nehring's blind mole rat (Spalax nehringi), southern vole (Microtus levis) and marbled polecat (Vormela peregusna), the amphibians European green toad (Bufo viridis) and marsh frog (Pelophylax ridibundus) as well as the reptile species sand lizard (Lacerta agilis).

[6] The Lake Kuyucuk and its surroundings are situated in the coldest zone of Eastern Anatolia characterized with harsh continental climate.

That resulted in connecting of the artificial breeding islet with the lake shore at some places, which brings the birds in danger by predators.

[8][12][13] KuzeyDoğa proposed to set up a planning for water supply in the basin and to immediately reform the islet by digging a ditch around.
