Cobertura geográfica

The Yagorlytsky Kut Section of the Black Sea Biosphere Reserve (covering an area of 5,540 ha) is located in the western (distal) part of the eponymous peninsula, situated between the Yagorlytska Bay and the eastern part of the Tendrivska Bay. It forms part of the Ramsar Wetlands of International Importance “Tendrivska Bay” and “Yagorlytska Bay”. Within this section, the ecosystems of the Northern Black Sea region have been preserved in a natural state. The complex soil cover, along with variations in moisture and salinity, determines the diverse structure of the peninsula’s natural vegetation. Steppe vegetation is interspersed with lowlands covered in moisture-loving plant communities and extensive areas of saltmarshes.

Métodos de muestreo

Pedestrian transect bird counts were conducted along 6-kilometre transects. Each kilometre segment of a transect was surveyed separately. During the survey, all birds (both resident and those flying across the transect) were counted within a 600-metre-wide strip (300 metres on each side of the transect line). It should be noted that some species were also recorded beyond the standard transect width — up to 1,000 metres on each side of the line — including flying flocks of Calidris alpina (Linnaeus, 1758) and groups or individual Merops apiaster Linnaeus, 1758. Certain large or soaring species (Circus aeruginosus (Linnaeus, 1758), Corvus frugilegus Linnaeus, 1758, Cygnus olor (J.F.Gmelin, 1789), Pelecanus onocrotalus Linnaeus, 1758, Phalacrocorax carbo (Linnaeus, 1758), Haliaeetus albicilla (Linnaeus, 1758)) were observed up to 2,000 metres from the transect line. Consequently, the spatial uncertainty of coordinates for these species is greater than that indicated in the coordinateUncertaintyInMeters field and is approximately 1,100 metres and 2,100 metres respectively. The map and the line shapefile with the transect scheme are available in the Zenodo repository at the following link: https://doi.org/10.5281/zenodo.15151079. The attribute table of the transect line shapefile contains identifiers (matching those in the dataset) of the transects and their individual one-kilometre segments, as well as the coordinates of the start and end points of each segment. Binoculars (8x magnification) were used during the surveys.

Descripción de la metodología paso a paso:

1. Conducting bird counts along the transect, with bird observations recorded separately for each one-kilometre segment.
2. Transferring collected survey data into electronic spreadsheets.
3. Importing the summary spreadsheet into OpenRefine to identify and correct errors, standardizing species names according to the nomenclature used by GBIF, and converting the data to the DarwinCore standard.
4. Importing data into MS Access database and generating events and occurrence tables.
