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.

乌克兰基辅地区莎草科苔草的新发现
报道了被列入乌克兰红色数据册的稀有物种——博氏苔草的一个新产地。研究人群位于基辅地区,位于乌克兰翡翠网(左岸森林草原)的Divychky站点UA0000337内。居住人口的地区形成了一个单一的轮廓,覆盖了两个土壤湿度值不同的地区。在30平方米的面积上,发现了95个波西米亚C.bohemica个体。在观察时,所有个体都处于生殖年龄。已确定的由C.bohemica参与的植物群落变体属于芦苇纲,与乌克兰发现的大多数该物种的群落相似。作为对这一种群生存的威胁,可以考虑外来入侵物种变形金刚和同宿物种的日益参与。干旱期间频繁发生的火灾也对这些人口的生存构成重大风险。需要在有合适栖息地的地区进一步寻找波西米亚C。
