The damage of forests and rainfall in May has resulted in outpouring of forest ecosystems in Slovenia has been assessed the rivers Sava, Una, Vrbasa, Bosna and Drina to 214 million € without VAT.

Many the amount of the total planed annual timber villages have been completely flooded, people cuts (felling volume) of Slovenia. In Croatia, the lost their homes, their cattle, their property, ice-break has in the most part struck the area and unfortunately, floods have also taken of Gorski Kotar (Primorje - Gorski Kotar County). many human lives.

Hence, people are trying to return to their homes as compared to Slovenia, ice-breaks in Croatia soon as possible. Due to the fact that numerous had caused significantly less damage. However, households are oriented towards agriculture, the at more less the same time, specific areas in population of that area is faced with a difficult Croatia (Karlovačka County, Zagrebačka County and uncertain future and we hope that the help and Sisačko-moslavačka County) had been from all of us and from the governments of the affected by floods caused by abundant rainfall flooded countries will facilitate easier recovery and water inflows from the Slovenian territory. of the population and the return to a “normal The floods have activated torrents in forests and life“ for as much as possible. consequently caused significant damage on Even though the damage from floods is far forest infrastructure, notably forest roads. greater due to the fact that human lives were at It is necessary to mention that apart from risk, the foresters from the territory of Slovenia the economic function, the ice-breaks have and Croatia are still adding up damages in forest completely ruined the aesthetic function of the ecosystems that were caused by ice-breaks and destroyed forests. Furthermore, these natural floods at the beginning of February of this catastrophes have also significantly violated year. The ice storm, specifically, ice rain struck forest ecosystem services. Consequently, a the territory of Slovenia and a part of Croatia state of natural disaster has been declared in (Gorski Kotar) on the night of the 1st February, all disaster-affected areas in Croatia.
