That eastern species will thrive under forest conditions in this
region has not, of course, been demonstrated, but the great variety
of species planted successfully as shade trees in towns and cities, and
in many instances by settlers in the mountains and farming districts,
together with the marked success of various fruits introduced here,
would tend to indicate their adaptability to the climate. In many
respects the climate along the coast of Oregon and Washington is
similar to that found throughout the great hardwood region of the
Southern Appalachian mountains.

Of the many species occurring in the East, several appear preëminently
suited to experimentation because of their particular value in the
trade and rapid growth. Hickory is one of the most valuable of
eastern woods, and the supply remaining is probably least of all
the important species. It is largely used in the vehicle industry,
and because of the fact that the trade can use trees of small size,
and even prefers "second growth" hickory to the more mature form,
a crop can be grown within a comparatively short time. Shagbark or
pignut are probably the best species to plant. Red oak is another
species for which there is a large demand, and while it does not
equal the white oak in value, its more rapid growth makes it a
more desirable species to grow. The increasing scarcity of white
oak has brought about the substitution of red oak for many purposes
for which the more superior variety was formerly used exclusively.
Black walnut is a wood highly prized in furniture manufacture, and
this, coupled with its rapid growth, places it among the first
rank of hardwood trees. Chestnut, white ash, tulip, poplar and
black cherry are other species whose value for various purposes
suggests the possible advisability of their introduction.
