When the information for the timber supply analysis was collected in 1993, there were concerns about the uncertain nature of some of the data. The potential of some of these uncertainties to affect the timber supply forecast was tested by changing the values for certain critical factors in the analysis. Some of these changed values altered the timber supply forecast greatly, particularly in the short term.
Since the analysis, local Forest Service staff have further examined the information that was used for these critical factors. Their perspectives are outlined in the following discussion. Other factors in the analysis were tested and are discussed in the Timber Supply Analysis Report (see pages 21-34) but were not considered critical to this review and therefore are not included in this discussion paper.

The chief forester must carefully evaluate this information to determine the allowable annual cut and identify where improved information is needed for the next timber supply review. We encourage you to do the same. |
