Protected and Strictly Protected Wild Species (OG 07/2006), 56 species of fungi are strictly protected. In the „Red Register of fungi in Croatia” there are 71 species and thereof 21 species are found only in the nature park Medvednica (Tkalčec, 2007). Regarding mammals, the common forest species of special importance are bats represented with 24 species. Some of them inhabit the Veternica cave, whereas others inhabit the forests (Hamidović, 2005). Very high faunal biodiversity of Nature Park can be further seen in numerous papers in which Ćiković (2004) and Tutiš (2007) reports on ornithofauna, Janev Hutinec (2007) on amphibians and reptiles, Šašić (2005) on butterflies, Temunović (2007), Šerić Jelaska & Durbešić (2009), Šerić Jelaska et al. (2010) on other insects, etc. MATERIAL AND METHODS Materijali i metode Spatial data manipulation and analyses were done in frame of GIS. Digital elevation model with 50-meters spatial resolution was obtained from the Faculty of Science, University of Zagreb, as well as the spatial distribution of vascular plants mapped based on MTB 1/64 grid (Nikolić et al. 1998), and vegetation map at 1:50000 scale. Map of habitats at 1:25000 scale was obtained from the Nature Park, while one at 1:100000 from the State Institute for Nature Protection. All map layers were spatially harmonized using the same basic spatial unit. Used grid is based on the Central European MTB (abbreviation of German term „Meßtischblätter” that stands for a sheet of topographic map) grid that was proposed for mapping of Croatian flora (Nikolić et al., 1998). Basic MTB grid unit of 10’ longitude × 6’ latitude was further divided into 1/64 subunits, which were then used as a basic spatial units in subsequent analyses. Digital elevation model was used for the calculation of landforms as proxy for very diverse relief of the Nature Park in subsequent analyses. Landforms are classified in six categories (namely: valley; lower slope; flat slope; middle slope; upper slope; ridge) as shown in Fig.1. Topographic Position Index (TPI), necessary for calculating landforms categories was calculated using the neighbourhood of 1,000 meters. All above calculations were made using the Topographic Position Index extension for ArcView 3.1 from |
