The stumpage price changes were calculated and analyzed from the data collected by Timber Mart-South from 1998 to 2007. We analyzed the relationship between pine sawtimber stumpage prices and timber sale characteristics using hedonic pricing method. Quadratic transformation was employed for sale size and contract length. Stumpage prices increased with sale size, contract length, bid sales, and the number of bidders. The presence of above average or excellent grade, market conditions, and logging conditions also are positively related to stumpage prices.

표준적인 산림 조건을 가정하여 주요 경제수종의 기준 벌기령 입목가를 평가하여 임업의 수익성을 분석하였다. 벌기령의 입목가는 원목가격에서 벌목 운반비를 빼는 시장가역산법으로 평가하였다. 일본잎갈나무의 경우 기준 벌기령(30년)에서 입목가는 약 450만원/ha, 잣나무의 경우 기준 벌기령(50년)에서 입목가는 약 370만원/ha로 산정되었다. 이는 수확후 재조림비용 606만원 이하에 머물러 보조금이 뒷받침되지 않으면 갱신으로 이어지지 않는다. 육림비용을 포함하면 그 차이는 더욱 커진다. 장래에도 목재가격은 상승하지 않을 것이고 인건비는 상승할 것이므로 임업의 수익성은 더욱 악화될 것이다. 현재의 고비용 임업방식을 개선하지 않으면 지속가능한 산림경영을 실현하기 어렵고 공적 투자에 의존할 수밖에 없을 것이다. 따라서 임업의 비용을 절감하기 위해 천연갱신처럼 조림비용이 들지 않는 저비용 임업을 채용할 필요가 있다. 또, 임목수확의 비용절감을 위해 임도를 비롯한 임업 인프라에 투자해야 한다.

This paper presents and illustrates the application of a growth and yield model that supports both forest and mill side volume and value estimates. Traditional forest stand growth and yield models represent the forest landowner view of yield and economics. Predicted yields are estimates of what one would expect from a procurement cruise, and current stumpage prices are applied to investigate optimum management strategies. Optimum management regimes and rotation ages obtained from the forest side view are unlikely to be economically optimal when viewed from the mill side. The actual distribution of recoverable manufactured product and its value are highly dependent on mill technologies and configurations. Overcoming this limitation of growth and yield computer models necessitates the ability to predict and price the expected manufactured distribution of lumber, lineal meters of veneer, and tonnes of air dried pulp fiber yield. With these embedded models, users of the yield simulator can evaluate the economics of possible/feasible management regimes from both the forest and mill business sides. The simulator is a forest side model that has been modified to produce estimates of manufactured product yields by embedding models for 1) pulpwood chip size class distribution and pulp yield for any kappa number (Schultz and Matney, 2002), 2) a lumber yield and pricing model based on the Best Opening Face model developed by the USDA Forest Service Forest Products Laboratory (Lewis, 1985a and Lewis, 1985b), and 3) a lineal meter veneer model derived from peeler block tests. While the model is strictly applicable to planted loblolly pine (Pinus taeda L.) on cutover site-prepared land in the United States (US) Gulf South, the model and computer program are adaptable to any region and forest type.
