Tall trees are generally associated with high-biomass forests. This is particularly true for forests dominated by Sequoia sempervirens (hereafter redwood), the world's tallest tree species. Extreme decay resistance, the ability to survive high-severity fires, shade tolerance and prolific trunk reiteration (resprouting) make the species unique, allowing tall redwood forests to accumulate more biomass and store more aboveground carbon than any other vegetation type.
