Purpose. To give an objective assessment of the current ecological condition of artificially created objects of the nature reserve fund. Methods. Comparative-geographical, generalization, systematization, statistical, comparative-analytical, descriptive, cartographic. Results. Not all types of artificial objects of nature reserve fund of Volyn region are represented. There are 12 park-monuments of landscape art, 1 botanical garden, 1 zoo and no dendrological park. On the whole, the number of artificial objects of nature reserved fund in the region is the lowest in Ukraine. On the territory of the region there is an uneven distribution of artificial objects of the nature reserve fund. An analysis of the distribution of artificial objects of nature reserve fund by area revealed that the largest one is the park-monument of landscape art «Slovianskyy» (27,35 hectares). It is located in the Volodymyr-Volynskyy district. From 12 to 21,6 hectares of landscapes in Lutsk, Gorokhiv, Turiysk, Lyubeshiv and Kivertsy districts is occupied by the park-monuments of landscape art. In the Starovyzhivsky district, the area of park-monuments of landscape art is 2 hectares, while in other districts there are no areas for artificial objects of nature reserve fund. All arti-ficial objects of nature reserve fund were created in 1960-1990. Only one park-monuments of landscape art was created in 2018. It is called «Sydorukiv Park» and is located in the city of Horokhiv. Most of the park-monuments of landscape art are located within settlements and only 2 parks are located in the territo-ry of forestry. In total, more than 150 species of flora are protected in the territory of park-monuments of landscape art. Conclusion. As a result of the analysis, 3 species of flora were identified that grow on the territory of parks of monuments of landscape gardening art and are included in environmental lists (Epipactis hel-leborine, Syringa josikaea, Epipactis palustris). The most dangerous for them is tearing, digging, picking up bouquets, as well as a partial violation of the structure of ecotopes (deforestation, excessive recreation, etc.). It is proposed to strengthen the protection of these species by increasing the status of the nature con-servation object and assigning them to the territories of the nature reserve fund - botanical nature reserve of local importance.

Currently, 25 years after the Chernobyl NPP accident, even in areas with high levels of radionuclide contamination overt threats for the existence of vegetation are not detected. However, the reactions that show clear and undeniable signs of radiation lesions of certain species of plants are obvious. Genetic effects, which are the result of violations of the genome stability of and cause mutations, separation of populations, loss of individual species and possibly other effects are of particularly importance.

Purpose. Ecological description of rare species of plants of Cheremskyi nature reserve included in international Red lists and their distribution on territory of the Volyn area as of 2016. Methods. Comparatively-geographical, analytical, generalization, ystematizations, and also cartographic with the use of the computer programs of MapInfo Professional 8,0. Results. On the basis of analysis of the natural preservation network of the Volyn area certainly, that 3 objects of natural reserve fund have a most area on Volyn: Shatsk National Nature Park, National Nature Park “Prypiat – Stokhid” and Kivertsi Nаtional Nature Reserve «Tsuman Virgin Forest» in addition after an area Cheremskyi nature reserve is distinguished natural reserve thati s only on Volyn. It is in these objects of nature reserve fund is most of the species included in International Red Lists. It grows 6 species listed in Annex 1 of the Berne Convention (Aldrovanda vesiculosa L.), (Cypripedium calceolus L.), (Liparis loeselii (L.) Rich.), (Pulsatilla Latifolia Rupr. Pulsatilla), (Thesium ebracteatum Hayne), (Dicranum viride (Sull., Lesq.) Linbd.). Also grows 4 species listed in the IUCN Red List, European Red List: Crataegus ucrainica Pojark), (Cypripedium calceolus L.), (Silene lithuanica Zapal), (Tragopogon ucrainicus Artemcz). Species of plants included in to Annex 1 of the Berne Convention and Red list of the International union of conservancy, widespread as early as 4 landscape wildlife preserves, 1 to the forest wildlife preserve, 3 botanical wildlife preserves, 1 zoological wildlife reserve, and 3 botanical monument of nature, a total in 15 objects of nature reserve fund located throughout the region. Conclusions. Thus, analyzing the state of distribution in the Volyn region of the flora Cheremskyi nature reserve listed in the International Red Lists found that species growing within 15 separate nature protection objects that are not part of other objects of nature reserve fund, but the status and protection of rare form not always corresponds main goal, as the vast majority of them located within the forests where the active economic activity, therefore proposed a number of optimization measures.

On the basis of information of herbarium, literary and cartographic sources, field researches with subsequent by the critically system treatment of the collected material is give composition, levels and description of fitovariety of Vinnichchini. Gone into detail rarity flora of region, which is brought to various sozologichnikh conventions. Certainly the state of maintainance of types of rarity of plants after the levels of protected.
