摘要：Estimates are provided jor a threshold annual value of the non-market benefits of the forest for which the benejit-cost ratio would equal one. Monte Carlo simulation techniques are used to assess the sensitivity of the estimated threshold valuesJor various water mLlnagement strategies to changes in key assumptions abvut the prices of water and timber products. The analysis is then conducted under alternative assumptions about the growth rate of the value of annual benefits from the envirolUnental amenity of the forest.
