Study of forest plants species diversity in “Radomyshlske” forestry-hunting enterpise

The types of plant diversity on the territory Radomyshl Forestry in areas with different forest vegetation conditions were investigated. 21 species belonging to 15 families and 18 genera have been identified. main are determined (Pinus sylvestris-Vaccinium vitisidaea+V. myrtillus-Cladonia spp.+ Pleurozium; Pinus sylvestris-Calluna vulgaris-Pleurozium+ Cladonia ssp.; myrtillus-Pleurozium; sylvestris-Pteridium aquilinum-Vaccinium sylvestris-Calamagrostis arundinacea+Convallaria majalis) key indices (Simpson, Shannon-Viviver, Yvnyanyoti Margalef). Among forest, most widespread green moss-shrub pine forests, it is precisely this type that characterized by highest indicators richness peak Simpson Index – 0.89; Shannon-Weaver index 2.55 Margalef 3.21. moss-lichen contrary, indicate a rather poor diversity, namely Simpson's 0.75; 1.67 1.65. However, was maximum level equitability 0.9. A comparative analysis composition studied also carried out assess beta-diversity using Jaccard index. Shrub-green moss forests dominance blueberry gorse greatest similarity (0.7), as well moss-small herbaceous shrub-green (0.6); smallest small-grass green-mosslichen (0.2) Key words: beta-diversity, alpha-diversity, phyto-diversity, Polissia Ukraine, forests.
