The Dyje/Thaya River, together with the Morava River, is surrounded by the largest and ecologically most valuable floodplain complex of Central Europe. By straightening its course in the 1970s and 1980s, the Dyje/Thaya River was shortened by nearly 3.2 km. At the same time, dikes preventing floodings were built on both banks along the state border stretch of the river. These measures had to stabilise the border between Austria and Czechoslovakia on the one hand, and to ensure prevention and control on the other. The whole border stretch being 16.5 kilometres long was for a long time closed by the Iron Curtain. After the above water management measures, there were more than 20 remnants of the original river bed were preserved in the floodplain: these are backwater river branches/cut-off arms or oxbows of various character. Over the years, however, all these fragments of the original Dyje/Thaya riverbed became strongly silted, thus developing themselves towards a rapid termination. The modified river bed caused by puncturing the branches displayed low morphological value and straitening the watercourse contributed to accelerating water outflow from the landscape there. From a point of view of climate change adaptation, this was an unsatisfactory situation. Therefore, the river management authority proceeded to restoration measures.

Since establishing the Šumava/Bohemian Forest Mts. National Park (hereinafter ŠNP) in 1991 game and its management have been an important part of forest management there. The first NP’s Management Plan (Kučera et al. 1992) dealt extensively with the issue. According to its authors, Red deer (Cervus elaphus) numbers were extremely high within the whole NP and keeping and breeding of trophy game was preferred. Moreover, it was clear at that time that due to red deer’s migratory behaviour its management should not be limited only to the NP’s territory but it should be connected with that on the entire Protected Landscape Area’s territory as well as with the whole Šumava/Bohemian Forest Mts. foothills including the Bavarian side. 

According to experts, the current European spruce bark beetle (Ips typographus) plague is unprecedentedly the greatest in the Czech Republic’s history: it avoids neither the Jeseníky Mountains Protected Landscape Area (PLA,) in northern Moravia). In the time full of changes and twists, it has generated a number of issues and questions for forest managers, nature conservationists, and the general public; it stirs emotions and it is the subject of media discussions, where opinions are often mistaken for facts. The aim of this article is to take a closer look at the course of the European spruce bark beetle outbreak in recent years in the Jeseníky Mts. PLA, primarily through specific numbers.
