correlates with the severe depletion of timber resources that began during
the Middle Ages. While it took a while to achieve full deforestation, and
forestry reform, the straight grain needed for good riving came largely
from old-growth trees that were heavily shaded as seedlings and all their
early years. Riving really long planks is possible with such trees, and
declined as they were logged out, whether you're talking about planks for
clinker-built ships in Northern Europe or 30-40 foot cedar planks for
house boards on the NW coast of North America.
