项目摘要

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.

自欧洲定居点以来，对本地草原的工业干扰的足迹一直在上升，日益威胁到这些生态系统的保护。在加拿大西部，共同的工业活动包括油和天然气提取以及高压电源线结构，这两者都是重大影响到本地草原植被和下面的土壤。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，了解可以减轻的特定管理实践能源发展的有害影响，并在其之后最大化草地恢复完成，对于私人和公共牧场的经理以及这些工业很重要寻求最大程度地减少环境足迹的用户。在这项研究中，我们正在进行协作与Atco Energy Ltd.一致，为了1）评估被打扰的本地草原的恢复与高压动力线结构相关的工业活动，2）了解土壤的作用生物物理特征，包括微生物学，促进这种恢复，3）发展最佳用于保存草原的访问权限的管理实践。总体而言，信息这项研究提供的将减少本地草原工业干扰的未来环境影响，并促进能源开发与其他土地用途的整合。
