Abstract
Abstract The current conservation status of the rare vascular plant species and rare forest communities of the Volyn Upland (Ukraine) was characterized and analyzed. We found 14 rare plant species belonging to the Red Data Book of Ukraine in this territory (Lycopodium annotium L., Allium ursinum L., Cephalanthera longifolia (L.) Fritsch, Cephalanthera rubra (L.) Rich., Cypripedium calceolus L., Epipactis atrorubens (Hoffm.) Schult., E. helleborine (L.) Crantz, Lilium martagon L., Listera ovata (L.) R. Br., Neottia nidus-avis (L.) Rich., Platanthera bifolia (L.) Rich., P. chlorantha (Cust.) Reichenb., Galanthus nivalis L., Carex umbrosa Host) and 28 locally rare species preserved within the Volyn, Rivne and Lviv regions. The major threats for these species were indicated. Four rare associations, according to the Green Data Book of Ukraine, were studied in the Volyn Upland (Carpineto (betuli)–Quercetum (roboris) hederosum (helicis), Carpineto (betuli)–Fraxineto (excelsioris)–Quercetum (roboris) alliosum (ursini), Tilieto (cordatae)–Carpineto (betuli)–Quercetum (roboris) alliosum (ursini) and Pinetum (sylvestris) caricosum (humilis)) and their structure, main features and status were characterized in detail. The importance of further research, and the development of recommendations for the conservation and continued preservation of these forest ecosystems of the Volyn Upland was highlighted.
Highlights
Forest plant communities are one of the most widely distributed and valuable vegetation types in the territory of Western Ukraine

Summary
Degradation of the environment and all the components of ecosystems, especially forests as wood sources, are common in this region. This process is caused by the fragmentation of the forest vegetation, which occurs due to its being depleted mostly by felling and recreation. A transition to the balanced use of forest resources; and the minimization of direct and indirect impacts on forest ecosystems and their components. This problem can be solved by the protection of several plant species but by the conservation of whole natural forest communities. It will help to solve the threefold ecological problem – conservation of forests, rare species and these ecosystems in general (SHELYAG-SOSONKO, 2003)
