Chorology and conservation of rare fern species of rocky biotopes in the Polissya part of Zhytomyr Region

Abstract

and conservation of rare fern species of rocky biotopes in the Polissya part of Zhytomyr Region.

The genus Woodsia R. Br. in Ukraine (Woodsiaceae)

“…Bezsmertna, 07.04.2015). Thus, it is most likely that the vicinity of Zhytomyr has (and had) only one species growing -namely, W. ilvensis, which is also confirmed by the authors' revision of the mentioned localities (Orlov et al 2016).…”

“…The populations of W. ilvensis that grew on granite walls on rocky banks of the Teteriv river have probably disappeared as a result of raising water levels by 17 m and flooding the lower parts of the rocks following the construction of a flax mill dam (Orlov et al, 2016). Mount Osiianka, which was located on the right bank of the Hnylopiat river (4 km to the South from the Teterivka village in Zhytomyr district), was completely destroyed as a result of granite quarrying and mining activity.…”

“…A locality of the species in the vicinity of Stryzhivka village has not been confirmed, despite recent attempts, but it should be noted that currently there is no suitable granite habitat for the species in this area along the Teteriv river. Thus, the only extant location for this species in the Ukrainian Polissia is in the territory of the Skelia Krashevskoho geological natural monument on the right bank of the Hnylopiat river (Zhytomyr district) (Burchak-Abramovich 1949;Melnyk 2000;Orlov 2009;Orlov et al 2016;specimen deposited in KWHU).…”

Viscum album subsp. austriacum (Santalaceae R. Br.) in Volyn Polissia and Zhytomyr Polissia (Ukraine): current distribution, ecology and prediction of future spread

“…The insufficient (until recently) knowledge about the distribution of V. album subsp. austriacum in the studied area has resulted in the fact that despite its damaging effect, especially in the protected areas, this species was included in the lists of rare plant species of Zhytomyr (Orlov & Vergeles, 2011) and Volyn Regions (Danylyk et al, 2022). It is therefore impossible to launch an eradication campaign of V. album subsp.…”
