The Central Database for Cultivated Woody Plants in Europe Ginkgo (www.uni-duisburg-essen.de/ginkgo) now comes into existence, after many years of preparatory work, and at the instigation of the Board of the German Dendrological Society (DDG), and in co-operation with several universities, nurseries, arboretums, botanical gardens, park administrations, nature protection and memorial garden authorities. The homepage gives an insight into the status of the registration of remarkable trees (habitat, location, growth etc.) as well as providing further knowledge about trees and shrubs (nomenclature, origin, distribution, location, growth behaviour, morphology, use, propagation, diseases etc.). More information about the database Ginkgo is found in the same place under “General”, or through the database administration. All those who themselves, out of interest, within the framework of their practical work, or in the course of their studies and diploma work, are concerned in the collection and evaluation of data on trees and shrubs (e.g. registration of specimens, protection of woods, care of memorial gardens, new planting of woods, care of woods, scope of care) may participate in the construction of the Gingko Register (after creating username and password). The woody plants inventory of DDG (1974) and simplified are made available, scientific names are partly available via and are linked to the inventory. The making available of more data such as e.g. aids to age estimation, information about habitat demands, gardening or biological engineering application possibilities, etc., is being worked on. ...

Forest geneticists are frequently confronted with practical questions concerning the origin, the genetic variability, or the adaptability of trees, stands, or forest reproductive material. The posers of these questions can be biologists, ecologists, foresters, private forest owners, firms dealing with forest reproductive material, nature conservation organizations, and, of course, the forest geneticists themselves for their basic research. Awareness is growing within these groups that many of these questions can be answered with the help of genetic marker technology. However, the increasing number and variety of genetic markers available for forest tree species make it difficult for the so-called "end-users" of this technology to judge which type of marker is most suitable for the given purpose. The aim of this compendium is to provide end-users with guidelines for choosing markers that are suitable for the purpose at hand. ... [Information of the supplier]
