Keywords: algal reserve, algosozology, desmid algae, Chernihiv Polissya, quarry reservoirs. The object of the study is desmid algae of the Zavodske and Zavodske-2 quarry reservoirs The goal of the research was to prepare a scientific justification for the creation of a botanical nature reserve in a unique locality of desmids in the Chernihiv region (botanical monument of local importance "Algal reserve - Desmid wealth"). Methods: office processing of geobotanical descriptions, hydrochemical studies, hydrobiological studies, photography, classification, landscape approach. In the quarry reservoirs Zavodske and Zavodske-2, new species of desmid algae Cosmarium gibberulum Lütkemüller 1910 (Zygnematophyceae, Streptophyta) were discovered for the flora of Ukraine. Also in this reservoir, Cosmarium obsoletum (Hantzsch) Reinsch 1867 was found, which is considered a rare species of oligo-mesotrophic reservoirs. This finding is the first for the northern part of Chernihiv Polissya. In total, more than 40 taxa of desmid algae were discovered for the reservoirs Zavodske, and more than 30 taxa of desmid algae for Zavodske-2. The investigated quarry reservoirs are ecotopes in which the number of discovered species and the proportion of rare species of desmid algae among them are extraordinary and deserve priority protection. The uniqueness of these reservoirs lies in the fact that they differ in the composition of rare taxa, despite the close proximity of their location. A scientific justification for the creation of a botanical reserve object has been developed: a botanical natural monument of local importance "Algoreserve "Desmidiya Wealth".
