The footprint of industrial disturbance on native grasslands has been rising since European settlement, and increasingly threatens the conservation of these ecosystems. In western Canada, common industrial activities include oil and gas extraction and high voltage power-line construction, both of which are significant impacts to native grassland vegetation and underlying soils. As these activities form a key component of the economy in the Canadian Prairie Provinces, understanding the specific management practices that can mitigate detrimental impacts of energy development, as well as maximize grassland recovery following their completion, are important for the managers of private and public rangelands, together with those industrial users seeking to minimize their environmental footprint. In this study, we are entering into a collaborative agreement with ATCO Energy Ltd., in order to 1) evaluate the recovery of native grassland disturbed by industrial activities associated with high voltage power-line construction, 2) understand the role of soil biophysical characteristics, including microbiology, in facilitating this recovery, and 3) develop best management practices for the use of access rigmats for conserving grasslands. Collectively, the information provided by this study will reduce the future environmental impact of industrial disturbance in native grassland, and promote the integration of energy development with other land uses.

自欧洲人定居以来，工业干扰对原生草原的影响一直在增加， 日益威胁着这些生态系统的保护。在加拿大西部，常见的工业活动 包括石油和天然气开采以及高压输电线路建设，这两者都是重大影响 原生草原植被和底层土壤。由于这些活动构成了经济的关键组成部分 在加拿大草原省份，了解可以减轻影响的具体管理实践 能源开发的不利影响，以及最大限度地恢复草原 完成，对于私人和公共牧场以及工业牧场的管理者来说非常重要 用户寻求最小化他们的环境足迹。在这项研究中，我们正在开展合作 与 ATCO Energy Ltd. 达成协议，以便 1) 评估受以下因素干扰的原生草地的恢复情况： 与高压输电线建设相关的工业活动，2) 了解土壤的作用 生物物理特征，包括微生物学，可以促进这种恢复，并且3）发展得最好 使用通道垫来保护草原的管理做法。总的来说，信息 这项研究提供的结果将减少工业干扰对原生草原的未来环境影响， 推动能源开发与其他土地利用一体化。
