A new find of Carex bohemica (Cyperaceae) in Kyiv Region (Ukraine)

Abstract

A new locality of Carex bohemica, a rare species listed in the Red Data Book of Ukraine, is reported. The studied population is located in Kyiv Region within the Divychky site UA0000337 of the Emerald Network in Ukraine (Left-Bank Forest-Steppe). The territory housing the population forms a single contour covering two areas of different soil humidity values. On the area of 30 m2, 95 individuals of C. bohemica were discovered. At the time of observation, all individuals were of the generative age. The identified variants of plant communities with participation of C. bohemica belong to the class Phragmito-Magnocaricetea and are similar to the most communities with this species found in Ukraine. As a threat to existence of this population, increasing participation of alien invasive species-transformers and synanthropic species can be considered. Frequent fires occurring during drought periods also pose significant risks to the survival of this population. Further search for new localities of C. bohemica in the areas with suitable habitats is required.
