【 摘 要 】

The spatial distribution of 14 species of the orchid family (Orchidaceae) was studied at the left bankof the Koynikha River (Iskitimskiy District, Novosibirsk Region, Russia). Four species are listed inthe Russian Federation Red Data Book, four are listed in the Novosibirsk Region Red Data Book. Thenumber of individual plants is sufficient to ensure the long-term viability of each red-listed orchidpopulation. What is apparently one of the largest populations of Cypripedium macranthos in the regionis described (up to 5,000 individuals). Some of the orchids discovered require further study, namelyinterspecific hybrids of Dactylorhiza and Gymnadenia and distinctive floral developmental morphs ofPlatanthera. Аpplying the international criteria for allocation of an “Important Plant Area”, we nominate a new one for South Siberia. Based on the analysis of plant species composition of protected areasin Novosibirsk Region, we conclude that in situ preservation of orchids in the region is overall insufficient. It is therefore necessary to organize a new protected area “Orchid Zapovednik” in the categoryof “botanical Zakaznik” on 335 hectares with an explicit floral diversity conservation mandate andlong-term orchid population monitoring.
