Study of decorative of wood plants of Boroldaytau ridge within the boundaries of Syrdarya-Turkestan regional natural Park

Abstract

The article presents the results of studying and identifying habitats of rare and endangered plant species for developing recommendations on the conservation of plant populations within the Syrdarya-Turkestan Regional Natural Park. Research and evaluation of ornamental plants will allow to develop a system of cadastre of populations of ornamental and rare plants and clarify their species composition in the project area and assess the threat of their extinction. As a result of floristic study of the dendroflora of the Syrdarya-Turkestan State Regional Park, 46 species have been identified. As a result of three-year observations (2015-2018), a comprehensive assessment of the decorative features of plants in nature was carried out. Identified 8 species with low decorative qualities (Amygdalus spinosissima, Сerasus mahaleb, Hulthemia persica, Pyrus regelii, Rosabeggeriana, R. fedtschenkoana, R. kokanica, R.platyacantha); 11 species are not very decorative(Ephedraequisetina, E. intermedia,Astragalusugamicusssp. karataviensis, Calophacatianschanica, Atraphaxisfrutescens, A.karataviensis, A. spinosa, Cerasustianschanica, Cotoneasterallochroa, C. karatavica, Salixniedzwieckii); 12 medium-breeding species(Lepidolophafilifolia, L. komarowii, Halimodendronhalodendron, Morus alba, Atraphaxis virgata, Rhamnuscathartica, Armeniaca vulgaria, Cerasus erythrocarpa, Malussieversii, Spiraea hypericifolia, S.pilosa, Vitisvinifera); 6 decorative types(Acer semenovii, Pistaciavera, Celtiscaucasica, Atraphaxis pyrifolia, Sorbus persica, Amygdalus petunnikowii) and 10 high-species(Lonicera nummularifolia, Lonicera tianschanica, Juniperus seravschanica, Elaeagnusangustifolia, Fraxinus sogdiana, C. pontica, Crataegus turkestanica, Spiraeanthus schrenkianus, Salix alba, Tamarixramosissima).
