New site of Lycopodiella inundata (Lycopodiaceae) in the Bór Biskupi Basin (Silesian Upland). Lycopodiella inundata is a rare and protected pteridophyte species in Poland. It usually occurs in oligotrophic wetlands, mainly in transitional moors (Rhynchosporetum albae). Lycopodiella inundata has rarely been found at natural sites recently, probably due to unfavorable environmental changes, but appears more and more often at sites created by human activity, such as sand pits, gravel pits and the banks of fish ponds. In 2014 a new site of L. inundata was found in the eastern part of the Szczakowa sand pit (19°25′35″E, 50°15′18″N). In this area, L. inundata grows well and occurs abundantly in small conspecific patches, aggregations, or as solitary plants. The main threats to this site are expansion of forest and shrub vegetation, reed expansion, changes in groundwater level, and drainage of the area.
