Note for users

Since its first publication in 1982, this document has been extensively used by field workers, including the author Dr Robert C. Zimmermann himself. This has resulted in some useful feedback on the application of the guidelines which is summarized below for users.

In practice, it has been found that the guidelines are useful in clarifying assessment procedure. Figure 1 outlines this and serves to identify the particular steps to be undertaken in any given situation. The guidelines are also useful in helping to organize one's thoughts and the collection of data. The steps listed on pages 9-10 are especially applicable in this connection.

The Checklist is invaluable in making certain that no items are overlooked. Users have noted that it is helpful to make a separate Checklist based on Appendix I on a large scale, with plenty of room in the "Remarks" section to explain any qualifications of the data. This can then be completed in the field, to provide the information on which to base an assessment.

Future revisions of the text will incorporate more materials on mitigative measures, particularly on the protection of fauna and approaches to encourage useful regeneration of forests. This weakness should be borne in mind in using the present edition.

Finally, these guidelines have provided some structure or formality to environmental assessment in countries where the institutional framework for such procedures was minimal.
