Cover of Unasylva magazine 1960The Congress concluded that the multiple-use concept presented new challenges and new opportunities to foresters everywhere, with great prospects for additional services to the welfare of mankind, declared that it was not, however, a panacea to solve all forest management problems, as often one use must be dominant and other proposed uses must not then be detrimental to the major one.


In addition, it warned that there can be disadvantages to multiple use when it is inefficiently applied, although multiple use must be recognized as an important goal of forest policies.


The Congress was attended by 1.970 members, representing 65 countries.
