A sample of 231 independent timber investments were ranked by internal rate of return, present net worth per acre and the benefit cost ratio--the last two discounted by 3, 6.4. 7.5. and 10 percent--to determine if the different criteria had a practical influence on timber investment ranking. The samples in this study were drawn from a group of timber investments partially financed by Forestry Incentives Program costshare funds. The investment rankings were quite similar among the three criteria. Under constrained investment budgets, the benefit/cost criteria produced the investment selection with the greatest cumulative present net worth. Under less severe budget constraints, all three criteria produced investment selections with essentially the same cumulative present net worth.

In a 1964-1967 study on the Challenge Experimental Forest, seedfall was evaluated in 2-, 5-, and 10-acre circular clearcuttings. During the 4 years, 10 seed crops, ranging from light to bumper, were produced by ponderosa pine. white fir, Douglas-fir, and incense cedar. Seedfall ranged from 76 to 40,691 sound seed per acre (188 to 100,547/ha) for a single species in a given year. From 89 to 100 percent of each species' seed fell within an area 1 1/2 times the height of the average dominant tree. Overall, seed distribution was highly variable.

Avalanche dynamics equations are used to estimate flow heights, velocities, specific thrust pressure, maximum specific weight of avalanche debris, and runout distance for 12 avalanche case studies from the Colorado Rocky Mountains. Suggestions are made for using this engineering approach for avalanche zoning and land use planning.

Plantation forestry is the planting, managing, and harvesting of trees for the production of industrial wood. Originally published in 1983, the principal focus and contribution of the study lies in Roger Sedjo’s examination of the economic returns in twelve forest regions throughout the world. The results of the analysis strongly demonstrate the feasibility of major expansion of plantation forestry in a number of areas around the world and suggest the likelihood of major shifts in the principal supply areas. The results also have potentially important implications for countering the threats of deforestation. This title will be of interest for students of Environmental Studies.
