Giant Sequoia trees are protected within Sequoia National Park, Kings Canyon National Park, and Giant Sequoia National Monument.<\/span><\/p>\n\n\n\n<p><span class=\"s1\">The wood of the Giant Sequoia is highly resistant to decay which make it well suited for shingles and fence posts.&nbsp; But the wood is also fibrous and brittle, making it generally unsuitable for construction.<span class=\"Apple-converted-space\">&nbsp; <\/span>Large trees, due to their weight and brittleness, would often shatter when they hit the ground during harvesting, wasting much of the wood.&nbsp; Harvesting of Giant Sequoia ceased in 1924.<span class=\"Apple-converted-space\">&nbsp;<\/span><\/span><a href=\"https:\/\/en.wikipedia.org\/wiki\/Sequoiadendron_giganteum\">Source: Wikipedia contributors. &#8220;Sequoiadendron giganteum.&#8221; Wikipedia, The Free Encyclopedia.
