| description | The volume of incidental wood products due to the catastrophic windfalls that occurred on the 17th of September 2017 was estimated, at national level at 460 thousand m3, of which over 200 thousand m3 were registered in the area administered by the Bihor County Forest Administration. The main objective of this paper is the study of the changes that appear in the micro-relief
and of the influence of some environmental characteristics, in the beech stands (Fagus sylvatica L.)
from the Forest District Sudrigiu, Management Unit U.P. VII Văratec, Bihor County Forest Administration, Romania, as an effect of windfalls. The field observations had the purpose of: determining the displaced volume (DV); breast height diameter (D1.3); height of tree (HT); average root diameter (ARD); age (A); depth of micro-depression (DM) and depth of rock / parent material (DRP). Bifactorial linear regression of the DV according to the two characteristics of the tree (D1.3) and the soil (DRP) allows an assessment of the volume of displaced soil with an accuracy of 95%. The volume of soil dislocated in the beech stands (Fagus sylvatica L.) from the Forest District
Sudrigiu, Management Unit U.P. VII Văratec, Bihor County Forest Administration, Romania, evaluated with the help of the two-factor linear regression based on the basic diameter of tree D1.3 and the depth of the rock / parent material DRP and respectively the number of felled trees is between 2589.89 m3 for u.a. 100 A, partially affected and 13694.46 m3 for u.a. 104 A, affected by mass felling.
To acknowledge the total volume of dislocated land and of the specific volume (m3/ ha), for the different compartments, is important for the analysis and differentiation of the variants of works necessary for the forest reconstruction of the lands affected by windfalls. |
