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.

缺乏有关有益管理实践（BMP）（BMP）的有效性（BMP），涵盖农作物的农作物，群集种植以及改善本地树种物种的遗传学，作为用于促进治疗或造林实践的新型生物材料。这项研究将是第一个结合上述BMP的研究，而这一过程为量化这些实践的价值提供了基础，以促进土壤建设，侵蚀性控制和煤矿填海中的杂草管理。首先，我们将测试多年生本地草的功效，氮的年度固定物种和多年生天然福布，用于低输入杂草控制。其次，我们将征求一种新型的种植方法（即聚类种植），它留下了树木的聚集分布，该树木的分布是漫画的模仿历史分布，同时也加速了自然过程的开始，树木之间的自然竞争（例如，在树木之间进行互动竞争），提供栖息地，提供栖息地的栖息地，以便以后的耕种植物，以改进的遗传学的遗传和替代的遗传学，我们将逐步开发，我们将依从属于遗传学，我们会逐步覆盖遗传学的遗传学。长期。这项研究将在由Transalta Corp.运营的两个矿区开垦地点（Sunhills and Genesee）中实施这些BMP，并在艾伯塔省的Presparkland地区运营。本研究提出的抽样的广泛性质将允许对这些BMP的好处进行广泛的核算之一，以促进陆地固定方面的重新植被工作。我们预计，为改善土壤营养和营养循环，缓解侵蚀和杂草管理不利的景观的最佳管理做法提供了迫切需要的新知识。
