FLORA OF ODESA AIRPORT FOREST PARK

Abstract

Introduction. The flora of the area of study included algae, fungi, lichens and higher plants (mosses, ferns, golonasinny and angiosperm). They play an important role in the ecosystem of the Airport Forest Park. Odesa, create primary organic matter, emit oxygen, dispose of carbon dioxide, enrich the soil with nitrogen substances, decompose the remains of organic substances and process them into inorganic and are food and shelter for many invertebrates (worms, mollusks, insects) and vertebrates (reptiles, birds, mammals) organisms. Aim. The purpose of the work was to study the floristic diversity of the Airport Forest Park in Odessa. Methods. For the first time, the flora of the Airport forest was investigated during 2000-2022 by the route method. Determination of the species composition of algae, fungi, lichens, higher plants was carried out by light microscopy with the help of many determinists, atlases, monographs. Results. The flora of the forest park "Airportivsky" consists of 173 species (173 inland species taxa), which belonged to 156 genera, 60 families, 37 orders, 13 classes, 10 departments, 4 kingdoms and 2 empires (domains). The flora consisted of lower (Thallophyta) and higher (Embryophyta) plants. Lower plants were represented by algae (12 species), fungi (35) and lichens (2), higher – mosses (3), ferns (1), golonosin (6) and angiosperms (114). A characteristic feature of the taxonomic diversity was the dominance of angiosperms (114 species) in the species composition of the flora of the forest park. The most represented species were the leading families Asteraceae (20 species), Rosaceae (13), Fabaceae (11), Brassicaceae (6), Poaceae (5), Oleaceae (5), Aceraceae (4), Fagaceae (2), Lamiaceae (2) and Plantaginaceae (2). Leading genera of Aser l. (4 species), Artemisia L. (4), Agaricus L. (3), Medicago L. (3), Prunus L. (3), Trifoilium L. (3), Closterium Nitsch ex Ralphs (3), Amanita Pers. (2), Lactarium Pers. (2) and Plantago L. (2) formed the basis of the flora of the forest park. The most interesting floral finds are found in the flora of the park of the following species: closterium closteroid (Closterium closterioides (Ralfs) Luns et Peweters), glass Ola (Cyathus olla (Batsch) Pers.). Conclusions. For the first time in the flora of the Airport forest found 173 species (173 inland species taxa), belonging to 156 genera, 60 families, 37 orders, 13 classes, 10 divisions, 4 kingdoms and 2 empires (domains). Among them were found 12 species of algae, 35 fungi, 2 lichens, 3 mosses, 1 fern, 6 gymnosperms and 114 species of angiosperms.
