Abstract:

This paper presents research on the characteristics of natural regeneration of beech and fir in offspring and young forest development stages. Research is conducted in the natural forests of beech and fir represented on Korab Mountain. Data collection was performed through direct field research methods of test areas. The obtained data were processed through mathematical and statistical methods and are made appropriate analyses, of which the results are showed in tables and graphics. The paper includes data on natural conditions of the research area, and the situation with the parent plantation. Out of the carried research, the analysis was performed on the structure and development of the natural regeneration of beech and fir in offspring and young forest development stages. It was found that on the Korab Mountain the natural regeneration is in different stages of development but most of it is in offspring and young forest development stages. Most of the encountered individuals are aged between 5 and 20 years. Depending on the forest, stand density the participation of offspring in the total number of natural regenerations ranged from 59% with forest stand density of 0.5-0.6, 68% with forest stand density of 0.7 to 0.8 to 91% with forest stand density of 0.9 to 1.0, or about 85% of natural regeneration. The share of the individuals at young forest development phase ranges from 41% with forest stand density at 0.5-0.6, 32% with forest stand density of 0,7-0,8 to 9%with forest stand density between 0.9 to 1.0 or an average of 15%. At the same forest stand density and the same age, the individuals from natural regeneration of beech have some greater heights from individuals of natural regeneration of fir. Overall, natural conditions and the application of silvicultural and regenerative measures affect quality and structure of natural regeneration. The rise of forest stand density of 0.5 to 1.0 increases the number of individuals with poor quality, especially in fir. Of great importance for the survival and future sustainable development of beech and fir forests on the Korab Mountain is to grow quality and numerous natural regenerations of both tree species without compromising the quality structure of the parent trees and with no danger the ecological, economic, landscape and other features of these forests.

Ecological conditions and successional processes of the abandoned mountain pastures in the region of Malesh

Abstract:

This paper presents the results of the research of the natural characteristics of the mountain pastures in the region of Malesh and the processes of their overgrowth with forest vegetation. The researches include mountain pastures in the region of Malesh, which are distributed between 1200 and 1932 m above sea level. These mountain pastures until the 1990s were more intensively used for grazing of small and large livestock (sheep and cattle), but after this period there is a noticeable decrease in the livestock, especially sheep, which lead to overgrowing of large areas of these pastures with different shrubs and forest vegetation. The purpose of this paper is to determine the natural succession processes that occur as a result of the afforestation of mountain pastures and the process of their overrun and transformation into young forest plantations. From the results obtained in the research, it was determined that the natural conditions in the Malesh region are favorable for persistence of large areas of mountain pastures on which a substantial number of large and small livestock can be grown. However, the natural conditions in the particular region are also favorable for the development of forest vegetation, due to which a large number of pioneer species are significantly distributed in the pastures on which no livestock is fed. The strong regeneration ability of these species contributes to intensive afforestation of the mountain pastures, whereto a significant part of them lose their function and gradually transform into young forests. This process is assisted by the reduction of livestock in the region and the land use reduction of these areas. Thus, for a period of only 30 years in some parts of these pastures occur intensive overrun processes resulting with a complete transformation of these parts of mountain pastures into young forest plantations.

Scabiosa lucida Vill. (Dipsacaceae), a new species in the flora of the Republic of Macedonia

Abstract:

Scabiosa lucida is recorded for the first time for the flora of the Republic of Macedonia. Newly discovered population is located on Osogovo Mts, in north-eastern part of the Republic of Macedonia, nearby the border with Bulgaria. This finding confirms also the previous record for the Bulgarian side of the mountain. The species was recently recoded for another border mountain (ridge Kobilica on Šar Planina Mts), also at the other side of the border, this time in Kosovo. S. lucida is a mountainous element, distributed in central and southern Europe. The species belongs to the very complex group of Scabiosa columbaria. Certain features, like the hairiness of the leaves and the shape of the calyx-setae, in the fruit stage, make clear distinction between this and the other closely related species of the same group.

Keywords: Scabiosa lucida, Osogovo Mts., Republic of Macedonia.

Analysis of the connection between spatial factors with two types of forests in the Cemernica forest management unit, Bosnia and Herzegovina

Abstract:

The paper presents two types of forest in the area of management unit Cemernica in terms of preservation. Namely, all the forests were divided into two types, primary and modified. In the primary type we included all high forests with natural restoration, other types (coppice forests, culture…) we included in modified type. The results of the logistic regression showed what affects the position of these two types of forest. For this purpose, we included in the analysis the basic topographic variables (altitude, inclination and exposure) as well as the spatial units (the distance of the department from the settlement and the distance of the department from the nearest forest road). An analysis of the position of primary and modified parts shows that increasing the distance from the settlement increases the likelihood of the presence of primary forests, while parts of the forests that are closer to the forest roads are better preserved due to the higher traffic density in the parts of better preserved forests.

Keywords: primary forest, modified forest, logistic regression.
