This species forms the extreme edge of the timber line throughout nearly the whole extent of the range on both flanks. It is first met growing in company with Pinus contorta , var.

该物种在两侧几乎整个范围内形成了木材线的最边缘。它首先与 Pinus contorta , var. 一起生长。

The entire forest belt is thus swept and devastated from one extremity of the range to the other, and, with the exception of the resinous Pinus contorta , Sequoia suffers most of all.

整个森林带就这样从一端到另一端被扫荡和破坏，除了树脂状的扭叶松外，红杉受害最深。
