Due to the mechanism of epicormic branch regeneration, an individual redwood tree may be much older than any of its branches [C. Don) Endlicher 1847 Coast redwood, redwood, California redwood (Little 1980), coastal sequoia, palo colorado. Don in Lambert 1824 (Watson 1993); Sequoia sempervirens (Lambert) Endlicher (Peattie 1950). Described varieties, all horticultural, include adpressa, glauca, nana pendula, pendula and prostrata (Silba 1986). Evidence of multiple episodes of epicormic branch formation in the BCG tree. Isolated redwood grove in a frequently burned area near the southernmost range limit of the species, in the Santa Lucia Mountains [C. I bet you told her all your trees are sequoias—Grace Kelly in To Catch A Thief Sequoia sempervirens (D.

During historical times there have been Douglas-firs (Pseudotsuga menziesii) recorded as being taller than any coast redwoods now living. Nonetheless, it is fair to say that in the absence of continuing legal protections afforded the species within its native range, it would be at much higher risk than it is now. Lignotuber formation in Sequoia sempervirens: development and ecological significance. Canopy ecology of the redwoods has received a lot of attention in recent years; the best summary of the state of knowledge is provided by Sillett and Van Pelt (2007), who document the existence of an essentially complete forest ecosystem (including water sources and storage, nutrient sources and cycling, soil development, and fairly complex animal and plant communities) 60 m off the ground, with a relatively depauperate zone between that height and the ground. Most of these trees are remeasured at intervals of no more than three years; the tallest are remeasured yearly.

As a point of interest, when I first published this table in 1998, it had only 12 trees.

It proved to be extremely rotten, and yielded little merchantable timber.
