    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.

To study whether a regular satisfactory wood production could be achieved in the mountain reserve forests of Java, a study was made of natural regeneration and choice of method of selective felling on 3800 ha of the Goenoeng Gedeh complex. In 2 nearby forest areas (34 plots of 110.8 ha in total) and in another area (6 plots of 16.5 ha in total; parallel experiment) comparisons were made of methods of selective felling, to promote the best of the 200 timber species. At first trees for felling were selected by diameter, in later years primarily to obtain open places for regeneration. No more than 10 % should be cut, in view also of the cutting damage. The regeneration was periodically counted in 263 and 26 squares of 1 are, respectively.

In the native forest, regeneration was usually inadequate except sometimes in large clearings. Clearings of less than 10 are, especially those of I are often regenerated well with a mixed stand. Larger clearings of 0. 1-0.3 ha did not always regenerate well because of competition from weeds. An interval of 10 years between the selective cuttings was advised. The duration of the regeneration was estimated to be 50 years.
