The Coniferetum of National botanical garden has been founded in 1945. As of 2017, there are plants of 66 species. These plants belong to five plant families (Cupressaceae, Ephedraceae, Ginkgoaceae, Pinaceae, Taxaceae) and 22 plant genera. In accordance with The IUCN Red List of Threatened Species, these species are facing a higher risk of global extinction Critically Endangered (CR), Endangered (EN) and Vulnerable (VU), and would be threatened without an ongoing taxon-specific conservation programme (Near Threatened (NT)). The threats are a combination of the extensive exploitation, the spread of the introduced pathogen and a result of climate change. In order to indicate the plants’ growth characteristics, we use the diameter of trunks parameter (DBH - Diameter at breast height). There are eight trees from CR category, Abies numidica De Lannoy ex Carrière, which were planted in 1953 from seeds obtained from Adler (Russian Federation). Now these plants’ DBH are 44 - 71 cm. The grafts of Picea koyamae Shiras. from the same category were selected in the arboretum “Goverla” (Ivano Frankivsk region) in 2006; now we have four under stocks. The EN category is represented by the following plants. Thirteen Ginkgo biloba L. trees from Bucharest, planted in 1949 with DBH 30-50 cm; ten trees from Odessa planted in 1956 with DBH 25-50 cm. One Abies koreana E.H.Wilson young tree purchased in 2009 from Belgium. 21 trees Metasequoia glyptostroboides Hu
