A unique locality of Ophioglossum vulgatum (Ophioglossaceae) in forest-steppe part of Zhytomyr Region

Abstract

A new population of a regionally threatened species Ophioglossum vulgatum is reported. It is the southernmost record of the species within Zhytomyr Region and the only one in its forest-steppe part. The population is comprised of four parts with overall area of about 16 m2 and total number ca. 1000 specimens. A two-fold observation of the locality revealed fluctuation in number and density of specimens. The population is located within a settled area and is exposed to moderate anthropogenic pressure. Further monitoring is needed to detect population trend.
