Šumska Vegetacija I Šumska Zemljišta U Bosni I Hercegovini Prema Corine Projektu

Abstract

Ljudska populacija ima snažan uticaj na životnu sredinu, posebno na šume. Kako bi pratili, analizirali i razumjeli ove utjecaje, E.U. je razvila informacioni sistem pod nazivom: CORINE, program baziran na satelitskom mapiranju zemljišta i vegetacije. Razvijena je jedinstvena nomenklatura i metodologija za izvođenje CORINE programa za sve evropske zemlje. Bosna i Hercegovina je pristupila ovom programu 1998. godine. Sadašnji pokrivač šuma i šumskog zemljišta je analiziran i upoređen sa podacima dobijenim prije 30 godina.

The Dynamics of Stand Structure Development and Natural Regeneration of Common Beech (Fagus sylvatica L.) in Plitvice Lakes National Park

“…Beech forests with dead nettle are distributed throughout the Dinaric area of Gorski Kotar, Mala Kapela, and Velika Kapela, Velebit, in the Plitvice Lakes area and in northwestern Croatia (Samoborsko Gorje, Strahinščica, Ivanščica, Medvednica, Moslavačka Gora, Forests 2024, 15, 357 3 of 18 and Kalnik), which largely overlaps with the distribution range of the species Lamium orvala. This community is distributed at elevations from 400 to 800 m, on varying expositions, flat terrain, plateaus, smaller ridges, and gentle slopes [31]. In the Dinaric karst areas, the dominant substrates are Mesozoic limestone and Dolomites with some presence of silicate and silicate-carbonate clastic rock, with magmatic rock present only locally.…”

“…Common beech is the most widely distributed tree species (65%), followed by common fir (25%), common spruce (5%), and other tree species. Of the total forest area, 9500 ha are seed plants, 4000 ha are coppice forests, and the remainder is covered by various degradation stages of thickets [31,32].…”

“…Plant species nomenclature follows the Flora Croatica database [39], while names of plant communities, their syntaxonomy position, and the sociological association of individual species are taken according to Vukelić [31]. [36].…”

“…Digitisation of the horizontal projection of the canopy and development of the digital terrain map were performed using the ArcMap program v10.8.2, with data preparation and processing in MS Excel 2021 (Microsoft Corp., Redmond, WA, USA), while the programs Stand Visualisation System (SVS v3.36) and EnVision (v2.20, USDA Forest Service, Seattle, WA, USA) were used for stand visualisation and the vertical profile[36].Research of the floral system included the creation of vegetation relevés on the permanent experimental plot in 1980, which was followed up in 1988 and 2004 using the standard Central European Zurich-Montpellier method[37,38]. Vegetation relevés included compiling a list of all plant species found within the tree, shrub, and undergrowth layers that were observed, with records of their values related to abundance and cover.Plant species nomenclature follows the Flora Croatica database [39], while names of plant communities, their syntaxonomy position, and the sociological association of individual species are taken according to Vukelić[31].…”

Influence of Tree Attributes on Silver Fir (Abies alba Mill.) Transitioning to Higher Defoliation Classes Determined by Logistic Regression

“…Two forest stands, each 1 ha in size, were selected for use in measurement and analysis (Table 1). In Croatia, the most common fir forest communities include silver fir with hard fern (Blechno-Abietetum) and the Dinaric beech-fir forests (Omphalodo-Fagetum) of the western Dinarides [34]. Site A is a silver fir forest with hard fern and is a nearly pure stand.…”
