| Redwood Grain, Then and Now. Photo by Rob Huebschmann |
As a tree broadens and gains more girth the rings become nearly straight, as in this cross cut example in the photo above. By contrast, trees harvested at a young age will more clearly expose wider, separated rings. This sample from a local lumberyard shows the center of the tree and 13 rings, or 13 years of growth that received an abundance of rainfall or irrigation. Old growth center cuts are coveted for their tight grain, strength and rarity, so it is highly unlikely that this piece is one of them. It is difficult to imagine that the old growth lumber within this house could easily predate the American Revolution when it was harvested, sawn, and nailed to the wall. Some of the oldest Coast Redwoods date to the Roman Empire!
Coast Redwoods, or Sequoia sempervirens, are one of three trees identified as redwoods. Sequoia giganteas are known for their great mass, whereas S. sempervirens can be taller reaching heights over 300 feet. Their more unusual cousin, Dawn Redwoods, or Metasequoia glyptostroboides, are deciduous. Turning a russet in fall, the needles convince the misinformed that the tree is dying. Unlike its California cousins, the Dawn Redwood is native to China.
Here's the crux of this commentary: little remains of the old growth forests that are irreplaceable without the passage of hundreds if not thousands of years. In purchasing this home, and most early homes built throughout California, we are investing in the harvested redwood our predecessors took for granted as a resource. People who tear down these homes only to build their cheaper McMansions are contributing to and continuing the decimation of the California rain forests. I cannot think of a more clearer example of why we should preserve our older buildings as the optimal choice in sustainable processes.
