Invasive tree species are one of the most important threats to the riparian ecosystems. We aimed to check (1) whether invasive tree species have wider annual radial increments than native species and (2) which climatic factors (describing annual variability of air temperature and precipitations) influence radial growth of the investigated species. The study was conducted in the Warta river valley...
The aim of the study was to determine the effect of small forest water reservoirs on the radial increment of Scots pine and Norway spruce. We selected four small water reservoirs that were reconstructed in autumn 2006 in the Maskulińskie Forest District (northern Poland). Around each reservoir we placed transects according to the cardinal directions. At those transects we set up 10×10 m sample plots...
