Popis: The analysis of data from the first two decades of the 21st century shows that the area under forests in Bosnia and Herzegovina is gradually decreasing. In order to gain a detailed insight into this process, the paper will analyse the forest databases of the European satellite monitoring program Copernicus. This program, among other things, monitors the condition of forests in 39 European countries by using the High Resolution Layer (HRL). The HRL Forests database consists of 3 types of (status) products, and additional change products. The status products are available for the reference years 2012, 2015, and 2018. The status layers provide information on the Dominant Leaf Type and the Tree Cover Density at pixel level for the reference year 2018 in 10 m resolution. The Forest Type layer largely follows the Food and Agriculture Organization (FAO) forest definition. Also, the paper will use the data on forests from the CORINE Land Cover project for 2000, 2006, 2012 and 2018. The time-series includes a land change layer, highlighting changes in land cover and land use. The CLC Changes database will be analysed separately for three periods: 2000-2006, 2006-2012 and 2012-2018, due to more accurate data on forest losses. The results of the research show that forests in Bosnia and Herzegovina were reduced by 2.95%, in the period 2012-2018, where 2.55% of them were coniferous. Forests are primarily endangered by the process of conversion to transitional forest / shrub and fires.
Analiza podataka iz prve dvije dekade 21. stoljeća pokazuje da se teritorija pod šumom u Bosni i Hercegovini postepeno smanjuje. Da bi dobili detaljan uvid u taj proces u radu će biti analizirana baza podataka o šumama Europskog satelitskog monitoring programa Copernicus. Ovaj program, između ostalog, prati stanje šuma u 39 europskih zemalja koristeći bazu podataka slojeva visoke rezolucije High Resolution Layer (HRL). HRL Forest baza podataka sadrži tri tipa (statusnih) produkata i dodatni produkt o promjenama. Statusni produkti su dostupni za 2012, 2015. i 2018. godinu. Statusni slojevi daju informacije o dominantnom tipu lista i gustini šumskog pokrivača na pikselskom nivou za referentnu godinu 2018. prostorne rezolucije 10 m. Forest Type sloj u najvećem dijelu prati FAO definiciju šume. Osim toga, u radu će biti korišteni podaci CORINE Land Cover (CLC) projekta za 2000, 2006, 2012. i 2018. godinu. Vremenska serija uključuje i sloj o promjenama, koji prikazuje promjene u tipovima površinske pokrovnosti i načinu korištenja zemljišta. Baza podataka o promjenama (CLC Changes) za sva tri perioda bit će analizirana zasebno: 2000-2006, 2006-2012. i 2012-2018, radi veće preciznosti podataka o gubitcima šumskog tla. Rezultati istraživanja pokazuju da su šume u BiH u periodu 2012-2018. smanjile površinu za 2,95%, od čega su 2,55% četinari. Šume su najugroženije procesima konverzije u tranzicijsku šumu/šikaru i požarima.
