Standards for biodiversity: a proposal based on biodiversity standards for forest plantations

The 1992 Convention on Biological Diversity has not only focused attention on the concept of biodiversity it has also set expectations that the signatory nations will establish objectives. It is suggested here that the use of biodiversity standards could have a useful role in quantifying these objectives. The use of biodiversity standards is explored in connection with the levels of biodiversity In plantation forests. Forest plantations have been used for the basis of this investigation because such plantations could be used as large-scale experiments in which the use of standards, and the ecological monitoring of these standards, could be researched. The impact of intensive forestry practices on wildlife has often been the cause of concern and indeed controversy. Recently there has been a move towards the development of multipurpose forest plantations where management for recreation and wildlife takes place alongside management for timber. Some forest authorities are actively looking at ways of restoring levels of biodiversity in plantation forests. We suggest that if levels of biodiversity are to be restored, then forest managers must have something to aim for; that is, there must be a standard. The adoption of standards could provide a means whereby forest managers can meet biodiversity objectives. Standards may also enable managers to determine the effectiveness of those management practices which are intended to increase levels of biodiversity. We suggest a conceptual plan which combines a monitoring procedure with biodiversity objectives.
