刺参Calamagrostiscanensis(Michx.)美人。是一种分布广泛的根茎草本植物，在北美北部森林中能严重抑制白云杉(Picaglauca(Motch)Voss)幼苗的生长。我们回顾了这种草在四个演替阶段的动态：受干扰地点的定居；受干扰几年后草地对该地点的优势；随着盖层的发展逐渐失去优势；以及在成熟森林的下层中维持低水平的草。我们还描述了加拿大华山松与克隆生长和种子更新的关系，生长的环境条件，草地凋落物积累对针叶树苗小气候的影响，以及总体竞争能力。加拿大隐翅虫的防治策略如下。如果在伐木前林下几乎每一平方米都发现了这种草，除非使用除草剂或深度焚烧来杀死无性系，否则当林分被砍伐时，草将迅速蔓延。大云杉种子..。
Calamagrostiscanadensis (Michx.) Beauv. is a widely distributed rhizomatous grass that can seriously inhibit growth of white spruce (Piceaglauca (Moench) Voss) seedlings in the boreal forests of North America. We review the dynamics of this grass during four successional stages: the colonization of disturbed sites; dominance of the site by the grass a few years after disturbance; gradual loss of dominance with overstory development; and maintenance of the grass at low levels in the understory of the mature forest. We also describe C. canadensis in relation to recruitment from clonal growth and seed, environmental conditions for growth, the effects of grass litter buildup on conifer seedling microclimate, and overall competitive abilities. Control strategies for C. canadensis are as follows. If the grass is found in nearly every square metre in the understory prior to logging, there will be rapid spread when the stand is clear-cut unless clones are killed using herbicides or a deep burn.
