    A cost-effectiveness frontier is developed to compare economic and environmental tradeoffs associated with planting a riparian buffer to reduce stream temperature at the watershed scale. Results indicate that total welfare change and its distribution among sectors vary between scenarios. The policy selected may differ if riparian plantings are voluntary rather than mandatory.

    Sharply increasing timber prices in Minnesota reflect an imbalance in the ageclass distribution of the cover types that are most important to the forest industry. This paper examines the potential contributions that short-rotation forest crops grown on marginal agricultural lands can make in producing biomass for wood-base power plants and in supplying wood to the forest industry. A large-scale regional scheduling model was used to allocate forest and agricultural lands in order to minimize wood production costs for forest industry as well as power plant uses.

    This paper examines whether permanent farmland preservation programs are capitalized into farmland prices.
