This paper compares the forest structure, regeneration and distribution of dead wood in a virgin forest remnant and a closeto-nature managed beech -conifer mixture situated on Grmeč Mountain in Western Bosnia. The investigations were carried out in a 1 ha permanent sample plot and 35 circular plots (20 m radius) in the virgin forest and in 17 circular plots (25 m radius) in managed forests. The number of trees in the managed forest was significantly ( p ¼ 0.05) higher than that in virgin forest and the distribution of the number of trees per diameter classes had a decreasing trend, but with a different shape in the virgin forest compared to the managed stands. In the lower diameter classes, the stock volume recorded in virgin forest was half of that in the managed forest, whilst for higher diameter classes the cumulated volume of the growing stock was almost double in virgin forest. The young crops had a significantly lower presence in the virgin forest and a larger volume of dead wood was identified in the virgin forest than in managed stands. The study results are important in assessing the consequences of close-to-nature management on the forest structure and regeneration when compared to the condition in virgin forests.

U ovome radu opisan je prvi nalaz hrastove mrežaste stjenice (Corythuca arcuata) na području centralne Bosne, na dva lokaliteta. Kako je ovo prvi nalaz ove vrste na području Bosne i Hercegovine, potrebna su dodatna istraživanja biologije i štetnosti ovog insekta. Budući da je ovo strana i potencijalno invazivna vrsta, može se očekivati njeno širenje po teritoriji čitave Bosne i Hercegovine.

This paper analyses the conservation gains through High Conservation Value Forest (HCVF) assessments in two South-East European countries (Bosnia-Herzegovina and Romania). These are based on the review of the Draft Forest Stewardship Council (FSC) National Standards and HCVF Manuals and the results of the certification process of seven forest management units in the two countries. The review indicates that the application of Principle 9 (High Conservation Value Forests) and Criterion 6.4 of the FSC in Bosnia-Herzegovina and Romania was influenced by the size and nature of tenure (i.e., public or non-public land), rather than geographic location per se. The study also revealed that the assessment of HCVF has, for the first time, raised the question of conservation of cultural, historical and religious values as well as the sustainable management of those forests relevant for the basic needs of communities. These are values not currently covered at the present by the national conservation legislation in either of these two countries. Findings of this study in both countries demonstrates that there are certain conservation gains as a result of the HCVF assessment, especially related to ecosystem services, prevention of soil erosion and conservation of threatened, endangered and endemic species.
