Due to the increase in numbers and the lack of quality habitat, the wolf in the Republic of Croatia is expanding its habitat throughout the Dalmatian coast, even reaching the outskirts of settlements. What used to be a secondary habitat for the wolf, in which it only appeared occasionally, is now a primary habitat where reproduction takes place. In a wider area, until now, the occasional existence of a pack of two individuals was considered, and this case is the first documented evidence of reproduction in the investigated location.

Fitocenološka i ekološka tipifikacija staništa martovke (Hygrophorus marzuolus (Fr.) Bres.) u Bijambarama, Kanton Sarajevo

Biodiverzitet gljiva FBiH je slabo istražen, kao i areali rasprostranjenosti i ekološki uslovi pod kojima se gljive razvijaju. Takav je slučaj i sa martovkom te je glavni cilj rada prikazati ekološke uslove pod kojima se martovka pojavljuje. Za istraživanje smo uzeli metod Braun-Blanketa (1932) sa svim neophodnim ostalim parametrima vezanim za odabrano stanište, kao što su: fitocenološka pripadnost, florni element, indikatorska vrijednost i životna forma. Brojnost gljiva je data prema Tortić & Lisiewska (1971). Takođe je urađena hemijska analiza tla sa osnovnim parametrima. Martovka je zabilježena u šumi Abiet-Fagetum na lokalitetu Motike u okviru "ZP Bijambare". Ovo je novo nalazište martovke. U asocijaciji preovaldavaju primarne indikatorske vrijednosti. Vrste reda Fagetalia su najbrojnije unutar istraživane asocijacije. Od životnih formi preovladavaju hemikriptofite. Ukupno je utvrđeno 25 flornih elemenata iz 9 skupina. Najveći broj vrsta pripada subatlansko-submediteranskoj skupini. Florni element sa najvećim brojem konstatovanih vrsta je subatl-smed. Sreća pa je ovaj lokalitet poprilično udaljen od bilo kojih pješačkih staza jer je riječ o izrazito bogatom nalazištu martovke.

Medonosni potencijal dendroflore u Bosni i Hercegovini

The floristic composition and ecological characteristics of the area where honey grazing is carried out directly define the botanical origin as well as the physical and chemical properties of honey. The goal of this research was to determine the potential of woody and shrubby plant species in the apiflora from Bosnia and Herzegovina (B&H) based on the qualitative-quantitative palynological analysis of honey samples. In the research, 100 different types of honey samples from B&H were collected and analyzed. The melissopalinological preparations were prepared and analyzed in accordance with the Rulebook on methods for the control of honey and other bee products of B&H, as well as the methods proposed by ICBB. After the melissopalinological analysis, 25 plant families with a total of 30,000 pollen grains were identified, of which 16 were woody or shrubby plants with 18,126 pollen grains in the preparations. In the research, the most presented honey-bearing woody plants were: black locust (Robinia pseudoacacia), chestnut (Castanea sativa) and linden (Tilia sp.). Each analyzed palynological profile represented a unique combination of pollen from honey-bearing plants, as a specific biological imprint of the place of honey grazing.

Produktivnost HSM 208F forvardera u prebirnim sječama i planinskom području

Forwarders have been used in the forest harvesting in the world for decades and are irreplaceable in the first phase of wood transportation. The use of forwarders in Bosnia and Herzegovina is still in its initial phase. Although they are used sporadically, there are still many uncertainties about the operation of forwarders in selection stands. Especially if we take into account that the current practice is that machinery in the stand is allowed to move only along pre-defined routes, trail. This practice has been used for years with winch skidders. In this research, which was carried out in selective cutting and mountainous areas, it was determined that the most important influencing factors on the productivity of the forwarder is the unloaded drive distance, loaded drive distance and distance of load collecting drive. The productivity of 7.17 m³/h was determined for a loaded drive distance of 700 m and load collecting distance of 200 m. Forwarders require a different forest infrastructure than skidders if we want them to have competitive productivity.

Pan-europski kriteriji i indikatori održivog gospodarenja šumama: Institucionalni aspekti i mogućnost primjene u šumarstvu Federacije Bosne i Hercegovine

Overexploitation of natural resources have caused serious environmental issues, including climate change, biodiversity loss, habitat degradation, and soil and water pollution. The Pan-European criteria and indicators for sustainable forest management offer a tool to monitor progress and report on the sustainability of forest resources at sub-national, national, and regional levels. This paper examines the institutional aspects and possibilities of application of these criteria and indicators in the forestry sector of the Federation of Bosnia and Herzegovina (FBiH), aiming to improve forestry conditions and develop a coherent forest policy. A survey of 360 forestry experts from FBiH revealed that the majority support the positive impact of implementing the Pan-European criteria and indicators in the forestry sector. It was determined that the Ministry of Agriculture, Water Management, and Forestry of FBiH should be responsible for developing and collecting data related to these criteria and indicators. However, the primary barriers to implementation include a lack of financial resources, expertise, and commitment. While the public forest administration is formally prepared to apply these criteria, its current capacities are inadequate for effective implementation. Strengthening the capacity of the public forest administration is crucial to ensure the application of the Pan-European criteria and indicators for sustainable forest management. This would enable consistent and systematic monitoring and improvement of forest resource conditions and the overall state of the forestry sector in FBiH.
