The name 'Sequoia' is widely believed to honour which historical figure?

Pick one

or
A: Sequoyah, inventor of the Cherokee writing system

Austrian botanist Stephan Endlicher named the genus Sequoia in 1847 but never wrote down why; today the coast redwood keeps that name, while the giant sequoia has its own genus, Sequoiadendron. The most popular explanation is that he honoured Sequoyah, the brilliant Cherokee scholar who created the Cherokee writing system on his own. Some historians think the name comes from the Latin word for 'to follow' instead, so the mystery is still debated.

What natural event helps giant sequoia cones open and gives their seedlings the best start?

Pick one

or
B: Forest fires

Giant sequoias rely on fire ecology to reproduce. The heat of a forest fire dries out the woody cones, causing them to open and drop seeds onto the freshly cleared, nutrient-rich ash. Squirrels and beetles open some cones too, but fire also clears away competing plants and opens up the canopy, so the seedlings get plenty of sunlight.
