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赠款提案与2018年11月13日评估的Nserc Silviculture和Wood生产的NSERC工业主席提出。该提案由两个亚项目组成，即对造林治疗的中期监测和森林公路恢复的中期监测，用于林地殖民地保存的森林恢复。方法用于复制自然干扰后观察到的森林结构和成分。在NDBM中，部分收获（pH）用于维持森林结构和生物学遗产（例如Deadwood），以维持森林生物多样性所需的必要条件。我们提出了一系列研究，该研究将评估pH值对植物植物群落，地面居住的节肢动物群落，枯木动力学以及北方混合木林的结构和生产力的中期影响（即20年）的影响。我们将确定1）生物群落（植物和节肢动物）在pH和pH后恢复的速度和2）pH后的生产力是否会增加，从而补偿收获的树木。 道路开垦：该子项目将利用Agnico-eagle Mines计划在Val-D'or附近建立一个新的用于黄金和铜矿矿物提取的开放坑矿的事实。采矿项目以南的位于瓦尔 - 瓦尔（Val-D'or）的伍德兰北美（Woodland Caribou），被加拿大政府濒临灭绝。在该地区，为了促进资源提取，道路建设对驯鹿栖息地造成了干扰。栖息地的丧失加剧了这种驯鹿人口的不稳定，因此必须恢复其栖息地。道路主要通过提高捕食率来影响这一人群。然而，缺乏关于道路封闭在栖息地恢复的有效性的文献，因此很难提出恢复计划。该子项目将以通过森林道路的开垦来恢复部分驯鹿栖息地的目的。更具体地说，我们将评估道路开垦技术的有效性，以减少驯鹿捕食者（即黑熊和灰狼）对林业道路的使用。
