北方白雪松（Thuja occurentalis U）资源的可持续性在其分布范围内的许多地区都是一个问题，因为再生失败，难以将幼苗招募到树苗和杆（损失）中，以及收获水平超过生长。由于缺乏对北方白雪松生态学和造林学的研究，特别是因为北方白雪松是一种异常树种，造成了管理上的混乱。本文综合了最近和历史上的北方白雪松文献，重点是生态，再生，雪松野生动物的相互作用，和造林。虽然一些事后研究产生了矛盾的结果，一些使用的医生可以概括：北方白雪松是身材矮小，生长缓慢，腐烂倾向，除了在悬崖网站，并发现在早期和晚期的演替的立场。北方白雪松似乎是一个高度可变的物种，可以适应广泛的环境压力。由于这种资源的管理已被证明是困难的，北方白雪松造林的指导方针，需要在其整个范围。
Sustainability of the northern white-cedar (Thuja occidentalis U resource is a concern in many regions throughout its range because of regeneration failures, difficulty recruiting seedlings into sapling and pole (losses, and harvesting levels that exceed growth. Management confusion has resulted from the scarcity of research on northern white-cedar ecology and silviculture, particularly because northern while-cedar is an anomalous tree species. This article synthesizes recent and historical northern white-cedar literature, with a focus on ecology, regeneration, cedar-wildlife interactions, and silviculture. Although a number of post studies have produced contradictory findings, some generalizations of use to the practitioner can be made: northern white-cedar is of small stature, slow growing, decay prone except on cliff sites, and found in both early- and late-successional stands. Northern white-cedar appears to he a highly variable species that can adopt to a wide range of environmental stresses. Because management of this resource has proven difficult, northern white-cedar silvicultural guidelines are needed throughout its range.
