Abstract

A group of eight trees of Betula obscura Kotula ex Fiek was found on the territory of Potashnya Forestry, Kyiv Region, Ukraine. This dark-bark birch is listed in the Red Data Book of Ukraine. Two other species endangered in Ukraine, Diphasiastrum zeilleri (Rouy) Holub and Sparassis crispa (Wulfen) Fr., were also recorded close to this locality. On this basis, it is proposed to establish for the corresponding forest quarter the conservation status of a site of local importance.
