The study investigates the ecological distribution and abundance of Adonis vernalis in six natural habitats, identifying significant heterogeneity in species abundance. The analysis of Adonis vernalis habitats is an important step in the better understanding of this species place in the community assemblage related to their native environment: Plants of A. vernalis were counted in 25 m2 small scale plots from six specific habitats. The data was analysed towards a proposal for the potential distribution of plants in relation to a gradual habitat type.: There were identified two distribution scenarios in relation to the potential distribution of the plants in the habitat. Most of the small-scale plots showed an average of 50 plants/25 m2, while in three of the habitats were identified patches with more than 200 plants/25 m2. The forecast for plant presence and distribution indicates two possible outcomes - the first one indicates a maximum pick value of 30-40 plants/25 m2, and the second one shows two potential picks, at 30 plants/25 m2 and 120 plants/25 m2. The A. vernalis habitats present non-linear distribution patterns across the analysed small scale-plots, with the alternation of homogeneous with heterogeneous areas. Given its medicinal value and conservation status, we propose sustainable harvesting strategies that align with the ecological characteristics of the species.
