Basic principles, methodological approach to the CORINE Land Cover database–revision and correction of the CORINE 2000 (the first inventory) and preparation of the CLC2006 database are shown. The CORINE Land Cover 2006 project in Bosnia and Herzegovina (CLC2000 and CLC2006) is used as a main source of data in this paper. Special attention will be given to the metodological approach in identifying land use changes, land cover between 2000-2006. Bearing in mind that land use changes have been produced by using GIS technology, this work present GIS as a tool, while various possibilities of this tool regarding data analysis presented as well. The possibility of using the CORINE 2006 in land use planning processes in B&H is presented.

Ove šume su nastale pod snažnim antropogenim uticajem lokalnog stanovništva koje je sjeklo bukvu za ogrijev, a ne sistemskim gospodarenjem niskim šumama. Florističko - vegetacijske karakteristike kao i diverzitet ovih šuma je malo istraživan.

Virgin forests are relatively rare in the European temperate zone. This is due to the continuous use of forest historically and to increasing high population densities. Virgin forests are forest where the structure and dynamics have developed entirely under natural conditions, without any human interference or influence. This article assesses the Pljesevica forest in Bosnia Herzegovina to establish whether it can be classified as virgin forest. The structure and components of the forest were assessed in a 1 ha sample plot and four 400m2 quadrats. The values of the biodiversity indexes (as defined by Shannon and Weaver, Krebs and Meyer), species richness and evenness, the distribution of the different stand development stages and the proportion of dead wood lead to the conclusion that Pljesevica forest presents a set of structural and dynamic characteristics close to the ones typical for virgin forests in Europe, so in order to maintain its status as such, in the meantime it should undergo a protection management programme.

Proizvodne mogućnosti ovih šuma nisu potpuno iskorištene pa je potrebno uzgojnim zahvatima poboljšati njihovo stanje. U ovom radu analizirane su stanišne karakteristike panjače bukve na lokalitetu "Musići" kod Sarajeva. U 60-godišnjoj panjači bukve postavljene su (u proljeće 2007. godine) dvije eksperimentalne plohe na kojim su provedena dva načina prorjeđivanja i to: selektivna prorjeda i selektivna prorjeda sa čišćenjem zaostalih i loših izbojaka sa panja. Stanišne i strukturne karakteristike imaju odlučujući značaj kod odabira načina prorjeđivanja panjača u cilju prevođenja u viši uzgojni oblik. Prorjedu treba prilagoditi stanju u kojem se panjača nalazi. Selektivna prorjeda uz uklananje zaostalih i loših izbojaka sa panja treba biti osnov za buduće mjere njege u mlađim panjačama bukve.

Coppice beech forests in BiH covers an area of 351,000 ha which is about 13 % of the total area of forests and forest land. Production capacity under these forest habitats are not fully utilized and it is necessary silvicultural operations to improve their condition. This work investigates the structural characteristics of the habitat and coppice beech forest before and after thinning the example Musići tree coppice forests at the site near Sarajevo. The 60 year coppice beech forest were set up two experimental plots on which they are carried out in two ways thinning: selective thinning and selective thinning with cuting residual trees from stump. Habitat and structural characteristics have a decisive importance in choosing the way of translation tree coppice forests in the form of higher breeding. Thinning need to accommodate the situation in which the tree coppice forests located. Selective thinning with cuting residual trees in the lower tree floor should be given a basis for future measures in the care coppice beech.

Abstract: In Bosnia and Herzegovina from the all coppice forests the largest area occupy coppice beech forests. These forests are formed under strong anthropogenic influence of the local population which is used beech for fuel, and not as a system of management of coppice forests. Floristic vegetation characteristics and diversity of these forests is little explored. For this paper analyzed the characteristics and vegetation diversity coppice beech forests in the Canton of Sarajevo.

The evidence of detached areas of protected forests and natural objects and their insufficient representation has often been pointed out in Bosnia and Herzegovina. Additionaly, an abundance of unreliable data have been used and there is sometimes lack of knowledge about the situation on the ground. To get the real picture regarding the presentation, the volume, the type, the territorial spread of the protected forests and forest soils, as well as of the specific areas of forests and forest soils in Bosnia and Herzegovina, i.e. in the Federation of B&H, a detailed inventory has been performed. The research results were presented in this paper.

Summary We compared pristine and managed beech – fi r mixed forests in Bosnia to assess the impact of management on plant species diversity, vegetation structure and soil – vegetation interaction. Traditionally, management of Bosnian mixed forests has been by the opening of small gaps, similar to those occurring naturally. Species composition revealed three successional vegetation groups, two mainly in managed forests (regenerating and mature) and one mainly in pristine old growth forests. Managed sites showed a tendency to be more diverse in plant species than pristine sites, and were also more heterogeneous. Diversity was clearly explained by vegetation groups; mature managed stands showing the highest plant diversity and regenerating stands the lowest, both in terms of species richness and abundance distributions. Plant diversity decreased with canopy cover and increased with carbon concentration in the A h horizon, being accurately modelled by both factors. Although topographical conditions were homogeneous among sites, vegetation was very sensitive to small changes in environmental variables at the local scale. Vegetation refl ected a combination of past situations, represented by C in the A h horizon, and current conditions, represented by canopy cover and the C : N ratio in the LF organic layers, suggesting both sensitivity to present-day environmental conditions as well as the imprint of past events.

This paper presents the analysis of the floristic structure of the virgin forest and the managed forest of beech and fir with spruce (Abieti-Fagetum dinaricum Treg. 1957) at the location of Ravna vala on the north-eastern slopes of the mountain of Bjelašnica. The research was performed on systematically arranged experimental plot sets in the virgin forest and the managed forest stands. The results of the research, given in this work, present the contribution to the insight of the floristic relationships between the virgin forests and the managed forests of beech and fir with spruce in the mountain system of Dinarides.
