Аннотация: This methodological outline for estimating the primary production of forests and woodlands as part of IBP is based on preliminary documents circulated to more than seventy scientists directly concerned with such studies and incorporates many of their comments. The current version undoubtedly could be improved further but revision can be a never ending process. Rather than trying to produce a polished and generally acceptable version which might not have been ready before the end of IBP it was decided to publish at this stage and to issue corrections and revisions later.
