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.
加州红杉(Redwood),高耸入云,伟岸挺拔。它们虽然能长到80到90米,但是它们的根却不像许多高大植物那样,深深扎入土的深层来吸收养分,抵御风雨的侵袭。出乎意料的是,加州红杉的根,却只是散布在土地的浅层中。
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.
红杉这样浅根密布的生长方式,就是它长的如此高大的秘密,它的根大范围密布于地表,方便快捷吸收赖以生长的水分与养分,并将向下扎根的能量全部用以向上生长。
The General Sherman Tree in Sequoia National Park is the largest (by volume) tree in the world.
它们总是成群地相伴而生,并没有单独生长的。在地底下,它们的根彼此紧密地相连、绞缠叠绕,形成一片遍及上千顷的根网。它们一株连着一株,形成一片壮观的红杉林,除非狂风暴雨大到足以掀起整块地皮,否则没有一棵红杉会倒下。
