Leucojum vernum L. (Amaryllidaceae) is a bulbous geophyte from Central Europe known as medicinal and ornamental plant. Native population of this species can be found in the Peres Forest (parcels number 23-24) from Velyka Dobron Wildlife Reserve (Western Ukraine), monitored continuously since 2014. The aim of this study was the morphometric evaluation of the species and the chemistry analysis of the soil in which the species grow. According to our results the length of leaf sheath was the most variable parameter from the evaluated morphometric indicators (number of leaves, maximum leaf length and width, bract length, leaf sheath length, scape length, and bulb diameter). Correlations were found between maximum leaf length and scape length, but also between maximum leaf length and bract length. Soil chemistry analysis showed that the chemical properties of the soil are favorable for the studied plants. The soil pH was slightly acidic, the humus content and the supply of alkaline hydrolyzed nitrogen were high, and the amount of soluble P2O5 was moderate. Differences between the territories were found with respect to the soil agrochemical parameters.

The Wildlife Reserve of Velyka Dobron – which is located next to the village of Velyka Dobron (Hungarian: Nagydobrony), the fourth most populous Hungarian community in Transcarpathia – is the third-largest protected reserve of national importance in the country. We used a Geographic Information System to process and map the historical geographical place names of the settlement and the protected area (pieces of land within the cadastral boundaries but located either outside the settlement boundary or on its outskirts) based on the 1st, 2nd and 3rd military surveys, a cadastral map dating back to 1865 and the documents available in the Beregszász branch of the State Archives of Transcarpathian Oblast (fonds 125, description 6, file 344), as well as literary materials. As a result, a database comprising a list of 57 place names of the area was compiled. Likewise, a map of the pieces of land within the former cadastral boundaries and in the Nagydobron’ Wildlife Reserve was made. Analysis of forest area and land use changes showed that 16 pieces of land within the cadastral boundaries, but located either outside the settlement boundary or on its outskirts, have completely lost their former nature and as a result became part of the inner area of the settlement. Consequently, the compiled database and maps may help to specify the location of the ongoing research and clarify the accurate place of the earlier studies.
