    Union Catalogue of Agricultural Libraries in the Netherlands

    The WUR Library Catalogue contains bibliographic data on books and periodicals held by the libraries of Wageningen University and Research Centre and some 15 associated libraries. Holding data are added to each record.

    Subjects covered include Agrotechnology, Food and Food Production, Plant and Animal Sciences, Soil Science, Geo-information, Landscape and Spatial Planning, Water and Climate, Ecosystem Studies, Economics and Society.

    The joint collections of the participating libraries cover a substantial part of the internationally available scientific literature in these disciplines.

    As far as Dutch scientific literature in these fields is concerned, coverage can be considered near 100%, including much of the so-called "grey literature".

    All titles are entered in their original language. Keywords are added to facilitate subject searching.

    The database is updated every day and now contains over 830.000 records.

The beech (Fagus sylvatica L.) occurs in Europe in pure and mixed mesophile, deciduous, dominantly broad-leaved forests belonging to the phytosociological order of the Fagetalia silvaticae. This order includes the true beech forests united into the Fagion alliance and is represented in the area considered by the Fagetum boreoatlanticum (with 5 subassociations), and the mixed beech forests belonging to the Fraxino-Carpinion and represented by the Querceto-Carpinetum medioeuropaeum (with 2 subassociations). A further subdivision into variants and subvariants was made.

Some of the subassociations only occur on soils with a high watertable; others represent ultimate equilibrium stages in vegetational development under normal conditions, called climax vegetation types. Diemont concluded from his investigations that the climax types varied with the soil; nevertheless, within one climatic region, they were so much alike to be considered members of one climax swarm ('Klimaxschwarm'). However distinct differences between the floristic composition on northern or eastern slopes and on other slopes were found; within one region such types may be combined into one climax group ('Klimaxgruppe').

Physical and chemical soil analysis supported the botanical classification. Climatic data were added. Some notes were included on the ephemeral vegetation occurring after removal of the forest.

The natural forest types and the ecological conditions under which they occurred supplied valuable information on the most suitable tree and shrub species for reforestation and the treatment of the forest.
