Pogostost in obseg po?arov v naravi na Krasu in v slovenski Istri // The frequency and extent of wildfires on the Kras and in Slovenian Istria

摘要

Kras in slovenska Istra, ki sta del Kra?kega gozdnogospodarskega obmo?ja sta poznana po pogostih po?arih v naravnem okolju. Prispevek predstavlja rezultate raziskave o pogostosti po?arov v naravi v obdobju 1995–2012, njihovi razporeditvi po mesecih ter o obsegu opo?arjenih zemlji??. Ugotovili smo, da so bila leta z nadpovpre?nim ?tevilom po?arov pogostej?a v zadnjem desetletju, da je mesec z najve? po?ari marec ter da v letih z najve? po?ari niso nujno najobse?nej?a tudi opo?arjena zemlji??a. Za leta z najve? po?ari in najve?jim obsegom opo?arjenih zemlji?? smo pregledali vremenske razmere ter ugotovili, da so bila to leta s podpovpre?no koli?ino padavin in dalj?imi su?nimi obdobji.The Kras and Slovenian Istria, which are both within the “Kras forest management area”, are known for frequent fires in nature. The study presents the results of a research into the frequency of wildfires from 1995 through 2012, their occurrence by months, and the extent of burnt areas. It was discovered that the years with the above-average number of fires are more numerous in the last decade; that March is the month with the greatest number of fires; and that the years with the most extensive burnt areas do not necessarily coincide with the years with the greatest number of wildfires. Weather conditions were surveyed for the years with the greatest occurrence of fires and those with the largest extent of the burnt areas. It was established that these were the years with below-average precipitation and longer dry periods.
