This CRD grant proposal is presented in association with the NSERC industrial chair in Silviculture and wood production evaluated on 13 November 2018. This proposal consists of two sub-projects, i.e. mid-term monitoring of silvicultural treatments and forest road reclamation for woodland caribou conservation.Mid-term monitoring of silvicultural treatments: In natural disturbance-based management (NDBM), a range of silvicultural approaches are used to replicate forest structure and composition that is observed after natural disturbances. Within NDBM, partial harvesting (PH) is used to maintain uneven forest structure and biological legacies, such as deadwood, necessary to maintain forest biodiversity. We propose a series of studies that will evaluate the medium-term (i.e. 20 years) effects of PH on understory plant communities, ground-dwelling arthropod communities, deadwood dynamics, and the structure and productivity of boreal mixedwood stands. We will determine 1) how quickly biotic communities (plants and arthropods) recover following PH and 2) whether stand productivity increases after PH thus compensating for harvested trees. Road reclamation: This sub-project will take advantage of the fact that Agnico-Eagle mines is planning to established a new open-pit mine for gold and copper mineral extraction near Val-d'Or. South of the mining project is located the woodland caribou population of Val-d'Or, designated as endangered by the government of Canada. In this region, to facilitate resource extraction, road building caused disturbances to the caribou habitat. Habitat loss has intensified the precariousness of this caribou population making it imperative to restore its habitat. Roads have mainly affected this population by increasing predation rates. The lack of literature on the effectiveness of road closure on habitat restoration, however, makes it difficult to propose restoration plans. This sub-project will be conducted with the objective of restoring part of the caribou habitat by reclamation of forest roads. More specifically, we will evaluate the effectiveness of road reclamation techniques to reduce the use of forestry roads by caribou predators (i.e. black bears and grey wolfs).

该CRD拨款提案是与2018年11月13日评估的NSERC林业和木材生产工业主席联合提出的。本建议包括两个子项目，即造林治理中期监测和林地驯鹿保护林道复垦。造林处理的中期监测：在基于自然干扰的管理（NDBM）中，使用一系列造林方法来复制自然干扰后观察到的森林结构和组成。在NDBM中，部分采伐（PH）被用来维持不均匀的森林结构和生物遗产，如枯木，这是维持森林生物多样性所必需的。我们提出了一系列的研究，将评估中期（即20年）PH对林下植物群落、地栖节肢动物群落、枯木动态以及北方混交林的结构和生产力的影响。我们将确定1)生物群落（植物和节肢动物）在PH值变化后恢复的速度有多快；2)林分生产力在PH值变化后是否会增加，从而补偿砍伐的树木。道路复垦：这个子项目将利用Agnico-Eagle矿业公司计划在Val-d'Or附近建立一个新的露天金矿和铜矿开采的事实。采矿项目的南部是瓦尔德奥尔的林地驯鹿种群，被加拿大政府指定为濒危物种。在这个地区，为了方便资源开采，道路建设对驯鹿的栖息地造成了干扰。栖息地的丧失加剧了北美驯鹿种群的不稳定性，因此恢复它们的栖息地势在必行。道路主要通过增加捕食率来影响这一种群。然而，由于缺乏关于封路对生境恢复有效性的文献，因此很难提出恢复计划。这个子项目的目的是通过开垦森林道路来恢复部分驯鹿栖息地。更具体地说，我们将评估道路填海技术的有效性，以减少驯鹿捕食者（即黑熊和灰狼）使用森林道路。
