KELVEG – Roadside Vegetation of Lithuania

KELVEG – Roadside Vegetation of Lithuania (GIVD EU-LT-002) is a database that documents the diversity of roadside vegetation, tracks and monitors changes of non-native species’ impact on the roadsides, and adjacent habitats. The initiative was started in spring 2023. As of March 2025, 628 vegetation plots from randomly selected sites across the country have been included in the database. Vegetation plots were sampled along transects, starting at the edge of the roadside (road shoulder) and ending in an adjacent habitat. In each roadside part (road shoulder, first slope, second slope or flat part and adjacent habitat), 1 m 2 square-shaped vegetation plots were taken. Additionally, 100 m 2 square-shaped vegetation plots were sampled in adjacent habitats. In each vegetation plot, the cover of vascular plants and bryophytes was estimated using a percentage scale, and the cover and height of vegetation layers were measured. The aspect and inclination of slopes were measured using electronic compass and clinometer mobile applications, respectively. In each vegetation plot, soil samples were collected, and agrochemical analysis was performed to evaluate soil/substrate pH, the concentration of total nitrogen, humus, phosphate and potassium oxide, and microbiological activity. The data are available to potential users upon request from the corresponding author.
