ADAPTIVE CONIFERS ASSORTMENT FOR USE IN PUBLIC GARDEN AND PARK FACILITIES LANDSCAPING IN THE COASTAL ZONE OF THE SOCHI BLACK SEA REGION

The basis of ornamental plantings in public areas is an assortment of woody and tree-like plants adapted to specific conditions. Sochi Black Sea region is an actively developing region with favorable climatic conditions that contribute to the successful introduction and cultivation of various species and garden forms of ornamental species. The purpose of these studies is to develop an adaptive conifers assortment for using in landscaping of public garden and park facilities in the coastal zone of Sochi Black Sea region. The range of plants for such landscaping facilities should be represented by the most resistant and unpretentious species. The use of plants adapted to the conditions of the region will reduce the costs of plantings care. The offered range is developed based on the authors and dendrologists’ practical experience in the region and includes 20 evergreen coniferous trees species, 7 evergreen coniferous shrubs species (or low-growing shrub-like trees), 3 deciduous gymnosperms species. For each garden group, information is provided on the recommended use when creating garden and park facilities. The massive development of stem pestsxylophages (Lamprodila festiva L. and Phloeosinus aubei Perris) limits the creation of ornamental plantings with a predominance of coniferous plant species. However, evergreen coniferous shrubs (thuja, juniper, etc.) are year-round structural elements of any landscaping object; therefore, the refusal to use these species will sharply reduce the ornamental effect from plantings in the late autumn-early spring period. In this regard, a system of protective measures against stem pests is proposed for the cypress family species, including mechanical and chemical measures to control phytophages.
