Purchaser Response Perceptions by timber purchasers of the results of management for retention of green trees, snags, and down wood may be changing response by purchasers to Forest Service timber sales. Sentiments of timber purchasers toward timber sales with retention are almost uniformly negative. Reasons identified for disaffection include rigid contractual stipulations, difficulties in harvest engineering, and dubious profitability. Bidding behavior provides a quantitative indicator of purchaser response. The num- ber of total bidders for timber sales greater than 2 mmbf statistically has declined very significantly. The average number of total bidders for sales in this category was between 1980 and 1987 (n=62 sales, SE=); during the period of initiation of retention trees, snags, and down wood (1988 to 1990), the number of total bidders dropped to (n=28, SE=) (p<). Comparison of average active bidders, those bidders who actually bid higher than the minimum bid offer, declined signifi- cantly but less steeply from between 1980 and 1987 (n=65 sales, SE=) to from 1988 to 1990 (n=28 sales, SE=) (p<). From 1985 to 1990, the number of active purchasers has remained virtually constant (see fig. 2). The con- stancy since 1985 indicates that the decrease in number of active bidders occurred before timber sales included management for structural retention. Decline of total bidders is probably due to industry effects unrelated to purc
