Management practices for growing a forest in a post-mining industrial landscape

关于有益管理措施（BMPs）的有效性的信息，如多物种覆盖作物混合，集群种植，以及改进本地树种的遗传学作为促进植树造林或重新造林的新生物材料是缺乏的。本研究将是第一个联合收割机以上BMPs，并在此过程中提供了一个基础，量化这些做法的价值，促进土壤建设，侵蚀控制，杂草管理在煤矿复垦。首先，我们将测试多年生原生草，一个固氮的一年生物种和多年生原生杂类草低投入杂草控制的效果。其次，我们将测试一种新的种植方法（即，第三，我们将利用改良的原生白杨遗传学来加速树冠覆盖的发展，并促进土壤建设和长期的碳固存。本研究将在阿尔伯塔帕克兰地区的两个矿区（SunHills和杰内塞）实施这些BMP。在这项研究中提出的广泛性质的采样将允许themost广泛的会计的好处，这些BMP促进土地复垦植被恢复的努力。我们期望为开发最佳管理实践提供急需的新知识，以改善受地雷影响的景观中的土壤营养和养分循环、减轻侵蚀和杂草管理。

Information on the effectiveness of beneficial management practices (BMPs) such as multispecies cover cropsmixtures, cluster planting, and improved genetics of native tree species as novel biomaterials for facilitatingafforestation or reforestation practices is lacking. This study will be the first to combine the above BMPs, andin the process provides a basis for quantifying the value of these practices for facilitating soil building, erosioncontrol, and weed management in coal mine reclamation. First, we will test the efficacy of perennial nativegrasses, a nitrogen-fixing annual species and perennial native forbs for low input weed control. Second, we willtest a novel planting approach (i.e., cluster planting) that leaves a clustered distribution of trees that moreclosely mimics historical distributions, while also accelerating the onset of natural processes such asintraspecific competition among trees and providing habitat for later successional understory plant species.Third, we will use improved genetics of native aspen to speed canopy cover development and facilitate soilbuilding and carbon sequestration over the long term. This study will implement those BMPs in two minedland reclamation sites (SunHills and Genesee) operated by TransAlta Corp. and Capital Power within theParkland region of Alberta. The extensive nature of sampling proposed in this study will allow for one of themost extensive accounting of the benefits of these BMPs for facilitating re-vegetation efforts in landreclamation. We expect to contribute critically needed new knowledge to developing best managementpractices for improving soil nutrition and nutrient cycling, erosion mitigation and weed management inmine-affected landscapes.
