Resource companies often cause large scale disturbances in the northern boreal forest. Restoration of these areas, often in the 1000's of hectares, is technologically challenging because these areas are not readily accessible by land vehicles. The purpose of this project is to develop an eco-restoration technology (ERT) for the Flin Flon/Creighton area that is suitable for application across large spatial extents. In the Flin Flon/Creighton area, the simple application of dolomitic limestone has not been universally successful. We will evaluate why liming is not always successful and develop a soil amendment that will promote revegetation of the Flin Flon/Creighton area. These amendments will first be tested in greenhouses and then beginning in year two of the project, applied in field scale plots. The effect of amendments on the type of metals present in the soil and the ability of these metals to disrupt ecosystem functioning will be assessed using advanced techniques available at the Canadian Light Source. In addition, we will investigate how these amendments are improving soil ecosystem functioning and how we can modify the amendments to account for the effects of climate change on the Flin Flon/Creighton area. Finally, at the end of five years, we will test if the amendments have resulted in a sustainable improvement in ecosystem functioning in the Flin Flon/Creighton area. If successful, this project will provide the first ecorestoration technology that will be suitable for application in Canada's northern boreal forests. This technology is expected to be commercialized by Prairie Plant Systems Inc. and be available to other resource companies operating in Canada's northern boreal forest.

资源公司经常在北部北方针叶林引发大规模骚乱。这些地区的修复通常在1000公顷的S土地上，技术上具有挑战性，因为这些地区不容易被陆路车辆到达。该项目的目的是为Flin Flon/Creighton地区开发一种适用于大范围空间应用的生态恢复技术(ERT)。在弗林弗隆/克雷顿地区，白云岩石灰岩的简单应用并不普遍成功。我们将评估为什么施石灰并不总是成功，并开发一种土壤改良剂，促进弗林弗隆/克雷顿地区的重新植被。这些修正将首先在温室中进行测试，然后从项目的第二年开始，在田间地块中应用。改良剂对土壤中存在的金属类型的影响以及这些金属破坏生态系统功能的能力将使用加拿大光源可用的先进技术进行评估。此外，我们将调查这些修正案如何改善土壤生态系统功能，以及我们如何修改修正案以考虑气候变化对弗林弗隆/克雷顿地区的影响。最后，在五年结束时，我们将测试修正案是否导致弗林弗隆/克雷顿地区生态系统功能的可持续改善。如果成功，该项目将提供第一项适用于加拿大北部北方森林的生态恢复技术。这项技术预计将由Prairie Plants Systems Inc.商业化，并可供在加拿大北部北方森林运营的其他资源公司使用。
