Species of the family Orchidaceae in Holovanivsk forests (west part of the Kirovograd region)

Abstract

Objective – to study the habitat conditions and populations characteristics of three species of the family Orchidaceae (Cephalanthera damasonium (Mill.) Druce, Epipactis helleborine (L.) Crantz and Listera ovata (L.) R.Br.) in new localities at the boundary of distribution. Material and methods. The studies were carried out in 2010–2017 on the territory of Blagovischensk and Holovanivsk Districts of the Kirovograd region. A semi-stationary study one the E. helleborine populations was performed. Results. In isolated forests cultures near village Roznoshenske 1 individual of C. damasonium and population of E. helleborine medium size were found. This population of E. helleborine is mature and stable. Also two populations of E. helleborine of small size was found near villages Manzhurka and Odaja in Holovanivsk District. The previously described population of L. ovata has not been detected in recent years and probably has not survived. Conclusions. The new locations of the three species of the family Orchidaceae complements the Information about geographical distribution and allows us to specify the southern limits of their areas in the region of study. The sites where rare species are found require protection as protected areas.
