Workshop held January 13-15, 1987, Nanaimo British Columbia, Canada.
This proceedings, representing 17 years of results from the Carnation Creek watershed study, contains 17 technical papers about the physical and biological
processes of the Carnation Creek ecosystem. These papers represent the scientist's viewpoint of results and their implications.
After each session of technical papers, the proceedings contain thoughtful commentaries from 6 panels of fish and forest agency staff and forest industry representatives. These commentaries present the practical, and often blunt, opinions of the usefulness of the technical papers in real life, with the final panel adding viewpoints from the United States perspective. I hope that readers will carefully examine these audience comments. Our plans for the future as scientists and managers must rest on the reality of actual communication, not what we think people "ought to know". Appendix 1 contains additional comments on this topic by Gordon Hartman.
Finally, the verbatim questions and answers of the audience to each session of technical papers and panelists are also included so that the extent of understanding or uncertainties is preserved.
The technical papers summarize an enormous range of new knowledge, ranging from upstream water and sediment transport processes to consequences in the estuary environment. They also illustrate large gaps in our knowledge such as the necessary recovery time for disturbed alluvial channel stabilization and valley bottom groundwater levels. If anything, the Carnation Creek experience has confirmed that 17 years is indeed a very short time span with respect to documenting the cumulative effects of forest harvesting on a small, relatively stable coastal watershed. The synthesis by Gordon Hartman in the final session underscores the care we must take in drawing apparently "simple" conclusions.
