Question

Did you know? Giant sequoias and coast redwoods in California have thick bark that acts like a fireman's jacket — some up to 60 cm thick. Wildfires that kill young trees barely affect adult sequoias. Moreover, sequoia seeds open ONLY in heat: their reproduction depends on fires.

Giant sequoias and coast redwoods in California have thick bark that acts like a fireman's jacket — some up to 60 cm thick. Wildfires that kill young trees barely affect adult sequoias. Moreover, sequoia seeds open ONLY in heat: their reproduction depends on fires.

Reuzensequoia's en kustwitsequoia's in Californië hebben dikke bast die als brandweerjas werkt — sommige tot 60 cm dik. Bosbranden die jonge bomen doden, raken volwassen sequoia's nauwelijks. Bovendien openen sequoia-zaden zich PAS bij hitte: hun voortplanting hangt af van branden.
