The present study aims to establish the degree of risk of fires on the territory of the State Forestry Enterprise Botevgrad (TD SFE Botevgrad), as one of the natural and most common disasters in forest ecosystems. Using the approved by the Ministry of Agriculture and Food national "Methodology for...

The accumulation of carbon in forest ecosystems supports to mitigate climate change, which makes seeking strategies for adapted forest management an urgent goal time. The European beech (Fagus sylvatica L.) is one of the main forest-forming species in Bulgaria and ensures forest areas with higher...

In last two decades a problem for determination of optimal rotation ages when considering not only wood production but carbon uptake has had big importance. The coppice stands in Bulgaria occupy approximately 47% of the forest area. The biggest part of it consists of species of genus Quercus which...

Environmentally-friendly management like 'Dowerwald' is a silvicultural method that unites in an unconventional way all concepts except clear cutting. The starting point for applying of this method in commercial forests is the monoculture and one-age felling plantations. Their transformation could...

The object of investigation is soil erosion risk in forest territories at Otovica watershed, part of Dzherman river. A methodical approach, which analyzes the main factors of soil erosion, determines the degree of potential and actual soil erosion risk for each subdivision, defined in forest...

An interdisciplinary approach has been developed for a comprehensive study of the restoration (increase) of the tree-line border. In essence, the approach is a detailed scheme in eleven steps, which can have universal application in the study of processes in the tree-line border in all mountains in ...

Experience of different European countries in application of coppice with standards has been studied - incl. essence of this silvicultural system, forestry aims, the most commonly used tree species, methods and stages for creation of coppice with standards forests, shape, structure and...

First dendrobiometric results (tree number, mean base diameter, diameter at breast height (DBH), mean height and over ground biomass of the stems and branches)of Paulownia tomentosa L. plantation in Chepino valley - the Northwestern Rhodopes are presented. The plantation was investigated in order...

Based on 54 Hungarian-oak, 63 durmast and 3 Turkey-oak sample plots in seed-tree dendrocoenoses, the above tree species have their structures in thickness and height investigated. Three types of asymmetry have been found to exist as differentiated according to average diameter with thickness...

Height-class volumetric table (without bark) for the Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) in the Western Rhodopes was made. On the basis of the algorithm of its development are before hand developed system of average heightclass curves (height-class table), as well as table for the...
