This article develops a global timber market model which captures how timbe
r supply reacts to future predicted increases in the demand for timber. Hig
her future demand is expected to increase prices, increase investments in r
egeneration, increase establishment of plantations, and expand output. Dyna
mic market responses imply a greater reliance on plantations in productive
regions, allowing large areas of natural forest in low-valued regions to re
main largely intact. Sensitivity analysis suggests that price, harvest, and
management are most sensitive to the rate of demand increase, the interest
rate, the cost of plantations, and access costs of natural forests. Two fo
rest conservation strategies are examined which predict the system-wide imp
lications of forest conservation in Europe and North America. The policies
indicate that whereas set asides can induce net conservation, harvests incr
ease elsewhere, particularly in natural forests.
