Despite liking this article and wanting more burns, that last parenthetical is misleading/incorrect. Giant sequoia need fire to reproduce. Coast redwood, which is more common, taller, and what most mean by just "redwood" very much do not need fire and reproduce mostly by stump sprouting. Which they do an awful lot of (source: live in redwood forest, have to cut sprouts back constantly).

Coast redwoods are designed for periodic fire and fire suppression does cause problems, like build up of ladder fuel allowing fires to reach the canopy, but reproduction is not an issue.
