FLORISTIC, ECOLOGIC AND PEDOLOGIC CHARACTERIZATION OF SEMI-NATURAL HAY MEADOWS FROM RODNA MOUNTAINS

摘要

In this study we analyzed in terms of flora, ecological and pedological aspects three semi-natural hay meadows in Rodna Mountains. They are located in the north east of Bistrita-Nasaud county in the Valea Mare village area. The altitudes at which the meadows are located vary between 749 and 1292.5 meters. To determine the floristic compozition we used the Braun-Blanquet method with intermediate values a€?a€?and the ecological requirements of plants was performed using the Ellenberg vegetation indices. Pedological characterization has been described as a result of observed excavated sections and physico-chemical soil analysis performed in a specialized laboratory. In this study we determined two grassland types and three soil types. Environmental requirements of the plants were similar in the three studied locations.
