Kremenets Botanical Garden 2000 taxa. The collection of trees and shrubs contains 217 species; medicinal - 111 species; fodder plants - 128 species of 29 genders; vegetable - 74 species of 8 genders; flower-ornamental - 220 species of 84 genders,fruit and berry - 66 species, 141 genders. In collection there are 270 species of the natural flora plants, including 11 listed in the Ukrainian Red book: Neottia nidus-avis (L.) Rich, E. purpurata Smith, Cephalanthera damasonium (Mill.) Druce from the family Orchidaceae, Galanthus nivalis L. from family Amary daceae, Lilium martagon L. from family Liliaceae, Allium ursinum L, Epipactis atrorubens (Hoffm. ex Bernb.) Schult.,
Chlamydomonas nivalis cell in combination with inorganic material could enhance the darkening over the snow and reduce the surface area of white snow. Due to the absorption of solar energy by the alga, albedo would be reduced and the darker areas on the snow where the blooms form would melt more rapidly. As a result, populations of "C. nivalis" would increase, creating a feedback loop that amplifies melting and reduces sunlight absorbance which contributes to glacier retreat and lowering albedo, as shown experimentally. This is concerning to environmentalists and climate scientists. "C. nivalis" can be used as a model species for studying
