The dendroflora of Taras Shevchenko recreation park in Rivne
Rivne is called the city of greenery and flowers because of the large number of green spaces, parks and gardens, among which the Taras Shevchenko recreation park is marked by the greatest species diversity. However, the parks’ dendroflora of the Rivne region and the city of Rivne in particular has not been the subject of special research.
Purpose of the article - to analyze the species composition of Taras Shevchenko recreation park’s dendroflora.
Methods - field (trip and stationary), biomorphological, visual.
The study found out that the dendroflora of Shevchenko park has 160 species, 59 genera and 31 families.
Results. Pinophyta are represented by 26 species belonging to three families (Pinaceae, Taxaceae and Cupressaceae) and ten genera (Pinus, Picea, Abies, Larix, Taxus, Juniperus, Thuja, Platycladus, Pseudotsuga, Chamaecyparis). Only three native species of conifers grow in the park: Picea abies (L.) Karsten, Pinus silvestris L., Juniperus communis L.
Angiosperms are represented by 28 families and 49 genera. The species diversity marks the families Rosaceae, Salicaceae, Betulaceae, Oleaceae. The families Ulmaceae, Caprifoliaceae, Cornaceae, Celastraceae have a small number of species. The families Buxales, Anacardiaceae, Rutaceae, Simaroubaceae, Platanaceae, Elaeagnaceae are represented by only one species.
Most species (65.8%) are introduced from different parts of the world (North America, Far East, Southern Europe, Central Asia). The study found out that most species originate from North America (Catalpa bignonioides Walt., Robinia pseudoacacia L., Acer negundo, Quercus rubra L.), and the lest number of species are southern European (Buxus sempervirens L., Castanea sativa Mill.).
The most common plants in the park are Syringa vulgaris, Aesculus hippocastanum L., Picea pungens Engelm., and the least common - Pseudotsuga menziesii (Mirb.) Franco, Castanea sativa Mill., Phellodendron amurense Rupr.
The Red Book of Ukraine includes 4 types: Syringa josikaea J.Jacq. ex Rchb., Larix polonica Racib. ex Wóycicki, Paeonia suffruticosa Andrews, Taxus baccata L.
