Redwoods really are very remarkable trees. We are so fortunate to be able to work with them here.
Coastal redwood, Sequoia sempervirens, are remarkable stable trees. They rarely fall, which is how they get to be thousands of years old. They prefer to live in groups, where they mesh their roots together, and shelter each other from wind. Those that live outside of a group stay shorter than forest trees, and typically develop multiple trunks that function as a group.
However, they are also remarkably weak in regard to their structural integrity. Limbs are easily broken away from their vertical trunks by wind. Snow, which is rare within their natural range, causes significantly more damage than wind, which is probably why their natural range does not extend into snowy climates. Trees with co-dominant leaders (double trunks that divide from single trunks above grade) have potential to split at the union of the double trunks. Such unions are typically at such acute angles, that the trunks press against…
