Poplars (Populus spp.) have been planted in Europe and Asia since very earl
y times. Known in the Near East as the "blessed tree'', poplars have been t
he primary timber producer in regions lacking natural forests in the northe
rn hemisphere. Now, though, we are seeing poplar plantations becoming part
of the forest resources even in the abundantly forested Pacific Northwest.
Though still a minor contributor to the world's timber supply, the area of
land planted to poplars is, nevertheless, increasing rapidly, particularly
in China, South Korea, and the United States. The 1992 report from the Inte
rnational Poplar Commission listed nineteen countries with at least 10,000
ha of planted poplars and seven with more than 100,000 ha. Much of the succ
ess of poplar plantations results from the breeding of fast-growing and dis
ease-resistant poplar hybrids. Accordingly, at least eleven countries suppo
rt poplar breeding programs. Uses of poplar wood range from peeled poles fo
r rafters and other elements of construction in agrarian economies to the m
anufacture of paper, plywood, oriented strand board, and engineered lumber
in industrial nations. Interest has also developed in poplar plantations as
a renewable source of energy.
