部分采伐已被提议作为在加拿大北方森林实施生态系统管理的一个关键方面。我们报告一个重复的实验位于西北部魁北克的北方混交林。2000-2001年冬季，对一个90年生的白杨优势混交林分进行了两种部分采伐处理，一种是分散采伐，另一种是400 m2林隙采伐，设计中还包括皆伐和对照。在接下来的八年里，活树，粗木质残体，再生和地面甲虫库存在可变的时间间隔。我们的研究结果表明，所有收获处理都创造了条件，
Partial harvesting has been proposed as a key aspect to implementing ecosystem management in the Canadian boreal forest. We report on a replicated experiment located in boreal mixedwoods of Northwestern Quebec. In the winter of 2000-2001, two partial harvesting treatments, one using a dispersed pattern, and a second, which created a (400 m 2 ) gap pattern, were applied to a 90-year-old aspen-dominated mixed stand. The design also included a clear cut and a control. Over the course of the following eight years, live tree, coarse woody debris, regeneration and ground beetles were inventoried at variable intervals. Our results indicate that all harvesting treatments created conditions
