РЕПРЕЗЕНТАТИВНІСТЬ РІДКІСНОЇ ФІТОБІОТИ НА ЗАПОВІДНИХ ТА ПЕРСПЕКТИВНИХ ДЛЯ ЗАПОВІДАННЯ ТЕРИТОРІЯХ ЗАЧЕПИЛІВСЬКОГО РАЙОНУ ХАРКІВЩИНИ

Abstract

Relevance of diversity researches in natural and urban protected landscapes is widely recognized in world. The aim of our work was to study the current state of the rare phytobiota of protected and promising objects of one of the most plowed areas of Kharkiv district – Zachepilovsky. This article represents the results of phytobiots studies in 5 preservation areas of Zachepylivskyi district in Kharkiv region and in 5 perspective sanctuary zones, which are planned to be created as a part of the ecological network. Almost all surveyed territories have remained in a slightly disturbed state. They give a fulfilling representation of the natural vegetation in studied zone: true and shrub steppes, floodplain oak and alder forests, saline and marshy meadows, coastal-aquatic and aquatic vegetation. The rare phytobiots include 13 protected plant groups, three of which (Stipeta capillatae, Stipeta lessingianaea, Stipeta borysthenicae), are listed in the Green Book of Ukraine and 26 species of rare flora, 10 of which are listed in the Red Book of Ukraine: Anacamptis palustris (Jacq.) R.M. Bateman, Pridgeon et M.W. Chase, Crambe aspera M. Bieb., Dactylorhiza maculata (L.) Soо s.l., Gladiolus tenuis M. Bieb., Fritillaria meleagroides Patrin ex Schult. et Schult.f., Ornithogalum boucheanum (Kunth) Asch., Stipa borysthenica Klokov ex Prokudin, S. capillata L., S. lessingiana Trin. et Rupr., Tulipa quercetorum Klokov et Zoz. The largest degree of rare phyto-diversity was perceived in wetland area - the Orel River Flood, where 2 groups from the Green Book of Ukraine, 4 groups from the Green List of Kharkiv region, 6 rare species from the Red Book of Ukraine and 8 from the Red List of Kharkiv region are growing.
