  • The AA. examine the hypothesis that soil chemical properties other than nitrogen supply partly explain the altitudinal changes in the rain forest. They also compare the soils on Volcan Barva with those on several other tropical mountains to see
  • if differences in soil chemistry are likely to be the cause of differences in forest structure between mountains.

  • This study presents an analysis of the distribution regarding the two main types of the novel forest decline in Norway Spruce stands. The investigated area is the Western part of the Harz mountains. Besides terrestrial methods color infrared
  • photography is mainly used to inspect the extent of novel forest decline in Lower Saxony. This method idnetifies different decline symptoms and small spatial patterns of decline. In addition, the sample density allows to investigate the spatial distribution
