Eco-restoration of large-scale anthropogenic disturbances in the Boreal Shield

资源公司经常在北方北方森林造成大规模的干扰。这些地区的恢复，往往在1000公顷，是技术上的挑战，因为这些地区是不容易通过陆地车辆。该项目的目的是为Flin Flon/Creighton地区开发一种适用于大空间范围的生态恢复技术（ERT）。在Flin Flon/Creighton地区，简单地应用灰岩石灰石并不普遍成功。我们将评估为什么石灰并不总是成功的，并开发一种土壤改良剂，将促进弗林弗隆/克雷顿地区的植被。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，应用于田间规模的地块。将使用加拿大光源现有的先进技术评估修正物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。此外，我们将调查这些修正案是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Flin Flon/Creighton地区的影响。最后，在五年结束时，我们将测试这些修正案是否导致Flin Flon/Creighton地区生态系统功能的可持续改善。如果成功的话，这个项目将提供第一个适合在加拿大北方北方森林应用的生态造林技术。这项技术预计将由Prairie Plant Systems Inc.商业化。并提供给在加拿大北方北方森林经营的其他资源公司。

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.
