Abstract
The article presents the results of an inventory of the current species diversity of early-flowering herbaceous plants found in the territory of the National National Park "Kоlsay lake". It was revealed that in the study area of early-born representatives of 11 different families represented by 22 genera and 26 species of ephemeral and ephemeric plants. The leading position in this taxonomic composition is occupied by numerous families of Ranunculaceae (6 species- 23%), Liliaceae (4 species- 15%), Scrophulariaceae (3 species- 11%), Brassicaceae (3 species- 11%) and others. For the identified plants, a rapid change in the age periods is established: latent, regenerative and generative; disordered sequence of phenological phases. Most of the identified plants are valuable and rare, 1 species Adonis tianschanica (Adolf) Lips is listed in the Red Book of Kazakhstan.
