Description, History

On the 19. November 2004 a storm event with wind speed up to 170 km/h destroyed about 12 000 ha forest in the High Tatra National Park (TANAP). During the following months, the dead trees had been removed in most areas, in some small areas not. It was likely that the nutrient cycling would differ widely between extracted, non-extracted and intact sites in the forest. The CarboTatra project started in spring 2005 to investigate changes in nutrient cycle and microclimatic conditions due to the windfall.

The study was conducted at three different sites in the windfall area at TANAP, so called EX, NEX and IF. At the extracted windfall site (EX, Danielov Dom) the dead wood had been removed shortly after the windfall event. At the non-extracted Site (NEX, Jami) the trees had not been removed. The intact forest site (IF, Tower Site) was chosen as reference site without damage by the windfall event. The aim was to choose three sites with only low heterogeneity within and between the sites.

On all 3 Sites towers were erected (IF 30 m, EX 10 m und NEX 6 m) for examination and particularly for comparison of the exchange of carbon dioxide between different ecosystems, as well as the determination of energy and water balance.
