Ornamental plantations play a very important role in urban construction and
improvement of settlements. They are one of the most effective ways to improve the living
conditions of residents. In 1971 the arboretum with an area of 2 ha was established in Ivano-
Frankivsk. Planting planning was done in such a way as, on the one hand, to decorate the
building of the Ukrainian Research Institute of Mountain Forestry, and on the other hand – to
place next to it a collection of the most important forest-forming species. Therefore, the
arboretum was divided into two parts: front, decorative, and rear, collectible, with a scientific
purpose. But in 1988 the arboretum changed its owner. Without proper care, many species and
forms of valuable introduced species died and fell out of the flora of the arboretum.
The purpose of our study was to conduct an inventory of plantations, systematic,
biomorphological and dendrofloristic analysis. For this purpose, the generally accepted
methods of floristic research were used. During the study of dendroflora, a list of species was
compiled, which were determined by "Dendrology". Systematic taxa were accepted by
Takhtadzhyan (1968). As a result of the research, 73 species, 1 hybrid, 5 ornamental forms of
woody plants were identified. These species and hybrid belong to 43 genera, grouped into 24
families. Analysis of life forms showed that of the total number of species and hybrids, trees
account for 69.1 %, shrubs – 29.6 %, lianas – 1.3 %. Among the representatives of the
arboretum, the share of deciduous tree species predominates – 76.9 %, and evergreen plants
make up 23.1 %. Systematic analysis of introduced tree species revealed 6 leading families. The
largest number of species has Rosaceae family, which includes 10 genera and 16 species. In
second place – the family Pinaceae – 6 genera and 11 species. The composition of 4 families
includes four species. Five families include 3 species (Betulaceae, Aceraceae, Magnoliaceae,
Tiliaceae, Caprifoliaceae). Such families, as Platanaceae, Oleaceae, Bignoniaceae, have 2 species.
According to the floristic division of the world, representatives of the introduced dendroflora
of the arboretum naturally grow in the Holarctic kingdom. A total of 73 species originate from
7 floristic areas. These species can be divided into 3 groups. The first group consists of 54
species, whose habitats are within certain floristic areas. Of these, the largest number comes
from the North American Atlantic Region – 41.1 %. 24.6 % of the total number of species
originate from the Eastern Asiatic Region (Larix leptolepis Gord.; Acer ginnala Maxim.; Ginkgo
biloba L. and other). Some species (6.8 %) (Sorbus intermedia (Ehrh.) Pers.; Picea omorica
(Panc.) Purkyne and other) come from the Circumboreal region. The second group consists of
15 species, whose habitats are within the two floristic areas (Circumboreal and Eastern Asiatic,
Circumboreal and Iran-Turan, Circumboreal and North American Atlantic Regions). The third
group consists of 4 species, whose natural habitats are within the three floristic areas. Taxus
baccata L. and Ginkgo biloba L. are the relict species in the arboretum.
Students and teachers of the Medical College have established a garden of medicinal plants
on the territory of the arboretum, where valuable species of herbs are grown. Today, the
Arboretum of Ivano-Frankivsk Medical College is a valuable dendrological object. Students have
the opportunity to get acquainted with introduced species, which have proven their suitability
for widespread use in landscaping and forestry. Further work will be carried out with the
involvement of students in the arrangement of arboretum plantations, as well as to study the
ecological properties of the main introduced species.
Keywords: Arboretum, species, floristic areas, life forms.
