This paper describes the protection of the flora and vegetation of the Mountain Jahorina. The total area of protected landscape Javorina is 11,546,68 ha. Area of protected landscape Javorina is characterized by its geological structure, hydrogeological and hydrological phenomena and processes, soil types, mezzo and micro-climate, fauna, flora and vegetation. Based on the flora and vegetation as the basic elements and creators of the ecosystem, a number of important habitats have been selected: mountain turfs, crevices of limestone rocks, subalpine dwarf pine community, mountainous parts with preserved communities of mountain maple, frost forests, travertine and peat coal area. After evaluation and categorization the following categories have been determined: Ia-strict nature reservations, Ib-wilderness area, III-natural monument and IVhabitat management area. Zone of I protection degree in the area of protected landscape consists of four separate units: Trijeska, Paloševina, Zlatna dolina javora and Dugo polje. In the zone of II protection degree there is Malo Dvorište and the habitat of the endemic species of Balkan Acer heldraichii subsp.visianii.
The paper presents the types of wetlands habitat Gromizelj which is of Europeanimportance. The review is made on the basis of studies of flora and vegetation andthe Guide of the types of habitats according to the European Union (EU) HabitatsDirective. Swamp Gromizelj is located in the northeast of Republic of Srpska (RS)and Bosnia and Herzegovina (BiH), in the municipality of Bijeljina. During theresearch the following habitats have been isolated: 3150 Natural eutrophic lakeswith Magnopotamnion-or Hydrocharition-vegetation type, 3270 Muddy river bankswith Chenopodionrubrip. p. and Bidention p. p. vegetation, 6430 Hydrophiloustall-herb fringe communities of plains and of the montane to alpine levels,Reedbeds, tall sedges and vegetation of Phragmito-Magnocaricetea, 91E0 Alluvialforests with Alnus glutinosa and Fraxinus excelsior (Alno-Padion, Alnionincanae,Salici-onalbae) and 91F0 Riparian mixed forests of Quercus robur, Ulmus laevisand U. minor, Fraxinus excelsior or F. angusti folia, along great rivers (Ulmenionminoris).
Two databases related to grassland in Bosnia and Herzegovina (B&H) have been used in this research-the Copernicus Grassland (GRA) and CORINE Land Cover (CLC). The data have been processed by using GIS tools, and the spatial distribution of grass vegetation in relation to three biogeographical and four elevation zones has been determined. By using the Copernicus Water and Wetness (WaW) database, an insight into the coverage of grass vegetation in wetlands has been obtained. In addition, the analysis of changes in databases determined the total amount and location of the largest grassland losses. Based on GRA database, B&H is one of the richest countries, with 22.4% of its territory covered by grassland. According to the CLC database, pastures occupy 6.3% and natural grasslands 5.6% of the territory of B&H. However, grassland is exposed to various anthropogenic and natural processes that affect its distribution, quality, functions, etc. The CLC database has been processed by extracting the grasslands (pastures and natural grasslands) and calculating their spatial coverage and changes which happened during the three six-year periods from 2000 to 2018. The trend of decreasing pasture areas and increasing natural grasslands has been noticed. The pastures are most endangered by the processes of conversion to other types of agricultural land, while natural grassland increased spatial coverage during the period 2012-2018 mostly due to the revitalization and grazing of burned areas in the region of Herzegovina. Grasslands have been particularly targeted for afforestation and cropland conversion at present.
