Coast Redwood, Redwood National Park.
"The House" group is a very dense group of Giant Sequoias in the Giant Forest in the Sequoia National Park in California.
加州紅杉(Redwood),高聳入雲,偉岸挺拔。它們雖然能長到80到90米,但是它們的根卻不像許多高大植物那樣,深深紮入土的深層來吸收養分,抵禦風雨的侵襲。出乎意料的是,加州紅杉的根,卻隻是散布在土地的淺層中。
This is an example of a "fairy ring" sprouted from a stump. All the sprouts are identical clones with exactly the same genomic material.
Two Giant Sequoias, Sequoia National Park. Note the large fire scar at the base of the right-hand tree; fires do not kill the trees but do remove competing thin-barked species, and aid Giant Sequoia regeneration.
紅杉這樣淺根密布的生長方式,就是它長的如此高大的秘密,它的根大範圍密布於地表,方便快捷吸收賴以生長的水分與養分,並將向下紮根的能量全部用以向上生長。
The General Sherman Tree in Sequoia National Park is the largest (by volume) tree in the world.
它們總是成群地相伴而生,並沒有單獨生長的。在地底下,它們的根彼此緊密地相連、絞纏疊繞,形成一片遍及上千頃的根網。它們一株連著一株,形成一片壯觀的紅杉林,除非狂風暴雨大到足以掀起整塊地皮,否則沒有一棵紅杉會倒下。
