Records of vascular plants, bryophytes and lichens from the Kamianska Sich National Nature Park in 2020 (Kherson Region, Ukraine)

Study Extent

The dataset contains co-occurrences of vascular plants, bryophytes and lichens recorded during 2020 in Southern Ukraine. The study area is situated in the central-southern part of the Black Sea Lowland in the southern part of the steppe zone of Ukraine, Kamianska Sich National Nature Park in Kherson administrative region.

Sampling

The dataset contains co-occurrences of vascular plants, bryophytes and lichens recorded during the 2020. in Southern Ukraine. The study area is situated in the central-southern part of the Black Sea Lowland in the southern part of the steppe zone of Ukraine, in Kherson .administrative region in Kamianska Sich National Nature Park. To obtain this dataset, we sampled 35 plots which had an area of 10 m2 (17 plots), 100 m2 (6 plots). The plots of larger size (100m2) which include smaller plots are marked as parent events in the Event Core. Sampling locations were chosen to cover different types of natural and seminatural open grassland habitats within the study area. In each plot, we recorded occurrences of vascular plants (shoot presence), all terricolous soil-growing bryophytes and lichens. For each 10-m2 plot, several environmental and structural parameters were recorded: cover of vegetation layers and of litter, rocks, slope, aspect, inclination, shrub layer height and herb layer height. Additionally, the complete relevés with following the EDGG methodology (Dengler et al. 2021) are available in the GrassPlot database (Dengler et al. 2018).

Quality Control

Some specimens of the vascular plants and almost all lichens and mosses were collected as herbarium for determination and verification after the fieldwork. After digitizing the data, we harmonised the taxonomic information according to the nomenclature sources: for vascular plants - POWO (2024), for bryophytes - An annotated checklist of bryophytes of Europe, Macaronesia and Cyprus (Hodgetts et al. 2020), and for lichens – The fourth checklist of Ukrainian Lichen-forming and lichenicolous fungi with analysis of current additions (Kondratyuk et al. 2021). Then we used GBIF Backbone Taxonomy (GBIF species matching tool: https://www.gbif.org/tools/species-lookup) for the taxonomic check and implemented minor corrections of species names regarding misprints and problematic taxa to avoid misinterpretation. We additionally checked and verified the header data of vegetation plots (Event Core and GBIF Relevé Extension, Occurrence Extension) using OpenRefine (https://openrefine.org/), ]and QGIS 3.22 (https://qgis.org) for quality control.

Method steps

1. Site selection, field research.
2. Identification of herbarium specimens of vascular plants, lichens, bryophytes.
3. Digitizing the field data forms.
4. Data checking and cleaning.
5. Transformation of the dataset according to the Darwin Core standards.
6. Taxonomic check, final quality control.
