Research on the distribution and the ecological characteristics of oriental hornbeam (Carpinus orientalis Mill.) and south European flowering ash (Fraxinus ornus L.) on the territory of Lozenska Mountain.


The aim of this study is to analyze the distribution of two of the most aggressive and adaptive shrub species - Carpinus orientalis Mill. and Fraxinus ornus L. in the territory of Lozenska Mountain and the peculiarities of their behavior and relationship in terms of their ecological characteristics. The growth dynamics' research and dendrobiometrical changes in the stands of both species was carried out in the period March, 2017 - September 2018. There are 71 experimental areas in 20 sub-divisions with pure and mixed stands with participation of both species. The results of the statistical analysis shows a higher density of the south european flowering ash than that of the eastern hornbeam. The eastern hornbeam dominates over the south european flowering ash as an area, including the stands in which it is mixed with the south european flowering ash. Both species are settled preferably in coniferous stands than in coppice plantations of oak, hornbeam and beech. The Eastern hornbeam shows a tendency to replace the south european flowering ash and this is evident from its prevalence of better habitats and mixed stands.
