GEOGRAPHICAL ANALYSIS OF THE NATIONAL PARK "TUZLOVSKIE LIMANY» DENDROFLORA

Abstract

National Natural Park lymany” was created in 2010 on the Black Sea coast in Odesa region. Because of the fact that there is no natural forest vegetation in the area, special attention in the process of inventory of the National Natural Park lymany”plant world was paid to dendroflora. 79 species of woody and semi-woody plants were identified on the coast of Tuzlovski lymany.Taking into account L. Takhtajan froristic globe zoning 10 geoelements and 4 groups of areals were allotted to them (natural areals were not established for three species of plants because of the old culture). It was found that dendroflora of National Natural Park represents heterogeneous formation, which includes 65.8% of plants with areals in Circumboreal floristic region and 34.2% of species with areals, completely located beyond its boundaries. South-American and Asian species, dominate among the latter, with their parts being qual. The part of aboriginal species constitutes only 19.0%. Aboriginal dendroflora is composed of wide-areal (mainly, European-Asian) species by 82%. It also includes three endemics of Eastern Europe (with pontic areals): Artemisia trautvetteriana, Astragalus pallescens, Thymus x dimorphus. Two thirds of spontanic fraction of dendroflora are formed by aboriginal plants, the third fraction – by adventive ones (Ailanthus altissima, Amorpha fruticosa, Elaeagnus angustifolia, Morus alba, Ribes aureum). Artificial tree plantations on the coast of Tuzlovski lymany are formed bi circumboreal species by 58.7%, by 35.0% - by Asian and South American in equal ratio. The National Natural Park lymany”dendroflora includes 5 species with high invasive avility.Transformer species Amorpha fruticosa, Elaeagnus angustifolia, spread of which requires constant monitoring on the territory of the observed object of natural reserve fund, deserve special attention.
