Hantaviruses are RNA viruses of the Bunyaviridae family, represented in the Czech Republic by three genospecies: Dobrava-Belgrade, Puumala and Tula. They persist in natural foci of infection. In 2004 to 2009, a local outbreak with 18 reported cases of nephropathia epidemica caused by Puumala hantavirus occurred in the Šumava mountains and foothills and was spacially associated with another outbreak in Lower Bavaria, Germany. In the Jeleni locality in the Šumava mountains at 880 m above sea level, we identified a natural focus of infection suspected to be the source of hantavirus infection in forest workers. The focus was characterized geobotanically as a montane mixed forest with the predominance of beeches within the association Dentario enneaphylli-Fagetum, alliance Fagion, sub-alliance Eu-Fagenion, in a cold climate region with a podzolic soil. The biocenoses where hantaviruses are circulating typically show higher microclimate humidity. Their characteristization can be helpful in predicting where hantaviruses are likely to circulate.

Tests for protection of spruce forest stands against spruce bark beetle (Ips typographus) by using anti-attractants were performed in specific conditions of protected areas in which standard sanitary cutting is not allowed. The experiments have shown that application of anti-attractants in a no-cutting zone can significantly reduce bark beetle attacks on the standing trees. In case when the trees at stand edges are not damaged by wind, there is possible to reduce the tree mortality by up to 73%, even in case of large bark beetle populations and even in living green trees growing immediately next to trees attacked by spruce bark beetle. On the other hand, anti-attractants are ineffective at stand edge segments either damaged by freshly wind-thrown or broken trees or wedged with wind-thrown areas, as it was shown in semi-application tests in the NP šumava.
