TIMBER AVAILABILITY FOR CROSSTIES
The consumption of wood products in the United States has increased during the past 20 years and is expected to increase further during the next 5 decades. At the same time, the area of commercial timberland has slowly decreased and is expected to decrease even further. In spite of these general trends, available timber resources will meet requirements for current and increased levels of crosstie production in the near future because crosstie production is a relatively small portion of total timber products production. Crossties can be made from lower-quality and smaller-diameter hardwood trees that are not used in the production of other major wood products, and the supply of hardwood timber is increasing and will continue to increase. Following the year 2000, however, hardwood timber inventories are expected to decline and, at the same time, the demand for hardwood timber is expected to increase sharply, which will tend to increase timber prices.
