Sažetak
In the area of Forest administration (UŠP) Gospić, during the project so far, the preparation of spatial analyses using the Geographic Information System (GIS) and the collected vector and raster layers has begun. The initiated analyses are aimed at gathering knowledge about the distinctive ecosystem properties of the beech coppice, and their differences in relation to other beech silvicultural types in the area. In addition to examination of the quantitative and qualitative characteristics, the possibility of determining their productivity on the basis of stochastic relationships was also examined, on the basis of which, certain recommendations can be made for their improved management. The GIS analysis included three main steps: (1) Collection of available spatial subsets, (2) transformation of layers and their aggregation within the spatial database, and (3) Determining the interrelationships using basic statistical methods. The first step in the analysis was the collection and consolidation of the forest inventory data i.e. management units, departments and sections with the primary goal of isolating beech coppice stands. As the basic basis for this purpose, the available spatial data of the forest distribution, provided by the company Hrvatske šume was used, which were taken over for this purpose from the investor. Vector data with the spatial distribution of structural and other characteristics of stands, up to the forest compartement level, formed the basis for all further steps in the analysis. From raster subsets we used products from Copernicus Land Service, namely: - Corine Land Cove (2018) to analyze the general condition of forest and other cover - Dominant Leaf Type (2012 and 2018) - for precise determination of the distribution of conifers and deciduous trees - Tree Cover Density (2012 and 2018) to determine the density of forest stands, respectively change in the period under review. - Water and wetness (surface cover moisture, 2018) - Product of Net Primary Production (NPP) of MODIS satellite (MOD17A3, annual data 2010 - 2020), taken from the NASA-USGS portal. In addition to the above, spatial subsets with a 30-year average for the period 1960-1990 of temperatures and precipitation (State Hydrometeorological Service) and digital terrain model in a resolution of 25m (State Geodetic Administration) have also been collected.
