Reforestation Of Harvested Timberlands In Mississippi: Behavior And Attitudes Of Non-Industrial, Private Forest Landowners, J. E. Gunter, Steven H. Bullard, M. L. Doolittle, K. G. Arano

Faculty Publications

Southern forests play an increasingly important role in the timber economy as per capita demand for wood continues to expand. Moreover, harvest restrictions in the Pacific Northwest in the early 1990s shifted a large portion of United States demand for softwoods to the South. In Mississippi, most of the forestland is owned by non-industrial private forest (NIPF) landowners. Approximately 314,000 NIPF landowners control 66 percent of the state’s forestland base (Hartsell and London 1995). The sizable acreage of timberland held by NIPF landowners nationally and in-state underscores the importance of their role in the timber economy and weighs heavily in …

The Land Expectation Value Calculated In Timberland Valuation, T. J. Straka, Steven H. Bullard

Faculty Publications

Appraisers often use discounted cash flow (DCF) techniques to value timber and timberland. Land expectation value (LEV) is a standard DCF technique applied to many timberland situations. LEV calculates the value of bare land in perpetual timber production and is often used to value evenaged pine plantations. However, it is also useful in the valuation of immature timber stands and uneven-aged timber stands cut periodically. These models have wide applicability in timberland appraisal situations.
