ELM -
(Ulmaceae) Elm wood was valued for its
interlocking grain, and consequent resistance to splitting, with
significant uses in wheels, chair seats and coffins. The density of the
wood varies due to differences between species. The wood is also
resistant to decay when permanently wet, and hollowed trunks were widely
used as water pipes during the medieval period in Europe. However this
resistance to decay in water does not extend to ground contact.
In North America the species most commonly planted was the American Elm
Ulmus americana, which had unique properties that made it ideal for such
use: rapid growth, adaptation to a broad range of climates and soils,
strong wood, resistance to wind damage, and vase-like growth habit
requiring minimal pruning; to this day, 'Elm Street' remains the most
common road name in the USA. |
