Abstract

Podolian-Middle-Dnieper geobotanical subprovince of Forest-Steppe zone and the belts of Artemisia-Gramineae Steppes and grass-Stipeta-Festuca Steppes of Priazov Black Sea Steppe subprovince of Steppe zone are the most well studied among twelve geobotanical subprovinces of the Ukrainian plains, while the lack of information on lichen species diversity found to be in Middle Russian subprovince of Forest zone and belt of grass-Stipeta-Festuca Steppes of Middle-Don Steppe subprovince of Steppe zone of this territory. Among twenty three administrative oblasts of the Ukrainian plains situated in twelve geobotanic subprovinces of three zones the highest lichen species diversity is found in Kherson oblast of the belt of Artemisia-Gramineae Steppes (464 species), Mykolaiv oblasts of the belt of grass-Stipeta-Festuca Steppes of Priazov Black Sea Steppe subprovince (389 species) of Steppe zone, as well as in Kharkiv oblast of Middle Russian subprovince (332 species) of Forest-Steppe zone of the Ukrainian plains on the basis of the Fourth checklist of lichen-forming and lichenicolous fungi including 2,106 of the total Ukrainian lichens. The lower lichen diversity is hitherto recorded from Rightbank Polessian subprovince (the highest species diversity 296 species in Zhytomyr oblast) and Baltic Forest subprovince (281 species in Lviv oblast) in Forest zone of the Ukrainian plains as well as Podolian-Middle-Dnieper subprovince (287 species in Khmelnytsk oblast) of the Forest-Steppe zone of territory mentioned. Insufficient level of data on lichen diversity is recorded for Middle Russian and Podolian-Bessarabian Forest subprovinces of the Forest zone, as well as the belt of grass-Stipeta-Festuca Steppes of Middle-Don Steppe subprovince and the belt of Stipeta-Festuca Steppes of Priazov Black Sea Steppe subprovince of Steppe zone. The same rather lower level of data on lichen diversity is found in Ivano-Frankivsk, Chernivtsi, Chernihiv, Vinnytsia and Sumy of Forest and Forest-Steppe zones; in Poltava and Kharkiv, as well as Cherkasy, Kirovograd, Mykolaiv and Donetsk oblasts in Forest-Steppe and Steppe zones; in Odessa, Kherson and Dnipropetrovsk oblasts of Steppe zone, as well as Zhytomyr oblasts in Podolian-Middle-Dnieper subprovince of Forest-Steppe zone. List of the rarest taxa of the regionally unique group (hitherto known from single or a few localities) proposed as candidates for including to Red Regional lists of 22 oblasts of the Ukrainian plains as far the whole nature protection activity in Ukraine is provided.
