Ecological reconstruction of degraded lands from the Zagăr improvement perimeter, Mureș County

Abstract

The problem that required the execution of technical improvement works was the existence of some sliding surfaces located on the slopes, behind which, after an initial stage of sliding, areas of excess water were formed, which without the execution of drainage channels would have led to the reactivation of the sliding processes of the slopes. In conjunction with the afforestation work, mechanical shaping of surfaces was also carried out, consisting of smoothing out roughness (ridges, mounds, slip steps) and levelling and levelling the topsoil. A greater number of species has been adopted in afforestation compositions to increase biodiversity, resistance of stands to impact with biotic and abiotic pests and thus increase their stability. Research under the theme aims to provide new insights into the behaviour of protective forest crops by comparing the data obtained. Observations have been made on the behaviour of species in mixtures and possible damage caused by abiotic and biotic factors. As far as erosion processes are concerned, observations were made on the areas where they are still active, the reasons why they have not been stopped and remedial solutions were proposed. Direct field observations and measurements were carried out, where sample squares were placed for each stationary unit under study.
