Conception

The aim of the Lower Saxony Forestry is to examine the adequacy to the local climate and growth properties of these exotic tree species. Thus, the habitat requirements of this species are to be determined for subsequent field trials. At installation of a Arboretum special attention was paid to the fact that no unstable monocultures are created, but if whole forest communities from the various climatic regions with the complete tree - shrub range of species to be planted.

In order to have an accurate picture of the development of the trees, they are involved in a long-term designed observation and measurement scheme. The height is determined every five years. Furthermore, various biotic and abiotic damage are detected and detained the plant-specific processes during the year. To check later suitability as commercial tree species, constantly nourishing wood removals are carried out in the various forest communities.
