The coastal redwood (Sequoia sempervirens) is a long-living tree native to California. Each mature tree contains an incredible amount of durable and splittable softwood, so nearly all were cut down between 1840 and 1970. Old-growth redwood trees are now a delicately preserved rarity, sometimes adorned with sensors or kept secret. The Santa Cruz County History Journal produced a wonderful volume of scholarly monographs covering the exploitation and preservation efforts.
Was any other population of long-living plants so reduced by harvesting? Did it also see intensive conservation efforts afterwards?
