Biodiversity Conservation in Botanical Gardens: The Collection of Pinaceae Representatives in the Greenhouses of Peter the Great Botanical Garden (BIN RAN)
Abstract
The work researches the role of botanical gardens in biodiversity conservation. It cites the total number of rare and endangered plants in the greenhouse collection of Peter the Great Botanical garden (BIN RAN). The greenhouse collection of Pinaceae representatives has been analysed, provided with a short description of family, genus and certain species, presented in the collection. The article highlights the importance of Pinaceae for various industries, decorative value of plants of this group, the worth of the pinaceous as having environment-improving properties. In the greenhouses there are 37 species of Pinaceae, of 7 geni, all species have a conservation status: CR – 2 species, EN – 3 species, VU- 3 species, NT – 4 species, LC – 25 species. For most species it is indicated what causes depletion. Most often it is the destruction of natural habitats, uncontrolled clearance, insect invasion and diseases.
