Mining activities in the City of the Greater Sudbury (CGS) in Northern Ontario (Canada) have resulted over the last century in serious damage to its environment. Logging and ore smelting led to large scale sulphur dioxide emissions and metal contamination. These factors damaged soil quality and vegetation, reducing plant, animal and microbial diversity inhabiting the region. Remediation projects were initiated to restore the ecosystem and to decrease industrial emissions. The land reclamation activities consisted mainly in soil liming and tree planting in areas damaged by mining operations. Assessment of areas that have been recently limed will be useful in predicting their sustainability and in determining earlier, fragile sites that are less responsive to land reclamation. This information is of paramount importance in establishing the long term-sustainability of reclaimed lands within the targeted region. In addition, several tailing regions have been reclaimed by local industries in the CGS. No detailed studies have been conducted on mine tailing in the Boreal Regions with regards to soil development, metal content, and their long term ability to sustain both plant and associated microbiological populations. Hence, this project aims are to 1) determine if recent soil liming and management practices (< 15 years) affect soil physico-chemical properties and microbial diversity and function in the GSR; and identify sites that are not responding to liming; 2) ssess if aerial and manual liming lead to the same outcomes: 3) determine physico-chemical properties of soils developed in tailings in the GSR: and 4) assess if soil developed in mine tailings can be suitable for plant growth and associated microbiological population diversity and sustainability in the GSR after reclamation. The present project will be useful for the Region in addressing key issues of the Sudbury Biodiversity Action Plan (SBAP) and Sudbury regreening Committee. The results of this component will make it possible to track progress and constantly make improvements on long term sustainability of terrestrial ecosystems. The project will develop a detailed environmental health map for the region based on site ecological characterization. It will harness the country's scientific capacity to study and find solutions to emerging issues that affect forest biodiversity. It is through the sustainable development that the project will contribute to the environmental, social, and economic well-being of the people of Northern Ontario, especially in the Greater Sudbury Region..

上个世纪，安大略省北部（加拿大）大萨德伯里市（CGS）的采矿活动对其环境造成了严重破坏。伐木和矿石冶炼导致大规模的二氧化硫排放和金属污染。这些因素损害了土壤质量和植被，减少植物，动物和微生物多样性居住在该地区。进行修复项目是为了恢复生态系统并减少工业排放。土地开垦活动主要由采矿作业损坏的地区的土壤限制和植树组成。评估最近被限制的领域将有助于预测其可持续性，并在确定对土地填海效应较低的较早的脆弱地点。该信息对于确定目标区域内回收土地的长期可持续性至关重要。此外，CGS的当地行业已经收回了几个尾部区域。关于土壤发育，金属含量及其长期维持植物和相关微生物学人群的长期能力，尚未就北方地区的矿山尾巴进行详细研究。因此，该项目的目的是1）确定最近的土壤限制和管理实践（<15年）是否会影响土壤物理化学特性以及GSR中的微生物多样性和功能；并确定没有响应石灰的站点； 2）SSESS是否会导致相同的结果：3）确定GSR中尾矿中开发的土壤的物理化学特性：4）评估矿山尾矿中的土壤是否适合于植物生长和相关的微生物种群回收后GSR的多样性和可持续性。本项目将对该地区解决萨德伯里生物多样性行动计划（SBAP）和萨德伯里（Sudbury Regresing Commant）的关键问题。该组件的结果将使跟踪进度并不断改善陆地生态系统的可持续性。该项目将根据现场生态特征为该地区开发详细的环境健康图。它将利用该国研究和寻找影响森林生物多样性的新兴问题的科学能力。正是通过可持续发展，该项目将有助于安大略省北部人民的环境，社会和经济福祉，尤其是在大萨德伯里地区。
