Обзор и флористическая оценка представителей семейства Cactaceae, занесенных в IUCN, произрастающих в оранжерее Ботанического сада Самарского университета

Abstract

The current state of the Cactaceae knowledge level and trends of species diversity preservation at botanic gardens being members of the Botanic Gardens Conservation International (BGCI) are presented in the paper. 182 species and 44 kinds of the IUCN Red List of Threatened Species were determined during the collection evaluation, with 89 species being endemic for Peru, Brazil, Chile, Mexico, Argentina and Bolivia. The degree of species vulnerability in natural habitat has been determined. The species were distributed according to the vulnerability status as follows: Critically Endangered – 4 species, Endangered – 11 species, Vulnerable – 23 species, Near Threatened – 7 species, Least Concern – 128 species, Data Deficient – 9 species. The most vulnerable collection species were listed: Mammillaria carmenae Castañeda, Mammillaria glochidiata Mart., Copiapoa esmeraldana F. Ritter and Haageocereus pacalaensis Backeb. The collection of Botanic Garden of the Samara University is compared with species at the botanic gardens of the North America, being members of the Botanic Gardens Conservation International (BGCI).
