Wetlands are multi-functional systems that provide a disproportionate number of ecosystem services given the spatial extent they occupy both nationally and globally. The ecological functioning of these wetlands is dependent on the structure of the landscape, which poses unique challenges when reclaiming wetlands in areas where resource extraction is occurring. Resource extraction mega-projects require that entire wetlandscapes be reclaimed and often involve timelines that necessitate the consideration of climate projections to create self-sustaining, naturally appearing wetlandscapes that meet policy objectives. To understand wetlandscape structure and guide reclamation planning and closure permitting evaluation, a random sample of 13,676 1-km² landscapes were subselected to identify 1684 permanent open-water wetlandscapes. A parsimonious set of landscape metrics were applied and compared across levels of anthropogenic disturbance and across natural regions (i.e., Grassland, Parkland and Boreal). Results demonstrated that permanent open-water wetlands are relatively rare (12.3% of our total random sample) and typically occupy less than 8% of wetlandscapes when present. The majority of wetlands in the study area are less permanent and more variable in nature than the permanent open water wetlandscapes created by megaproject reclamation, which has the potential to alter the distribution and size of open-water wetlands beyond their natural occurrence. Comparison across disturbance levels and natural regions yield statistical differences among landscape structure. General wetland landscapes representing a combination of disturbance level and natural region can be created for each metric to guide reclamation design and closure planning approval.

湿地是多功能系统，鉴于它们在国家和全球范围内的空间分布，它们提供的生态系统服务数量不成比例。这些湿地的生态功能取决于景观结构，这在进行资源开采的地区开垦湿地时提出了独特的挑战。资源提取大型项目要求对整个湿地景观进行开垦，并且通常涉及时间表，因此有必要考虑气候预测，以创建能够自我维持，自然出现的湿地景观，从而达到政策目标。为了了解湿地景观的结构并指导开垦计划和关闭许可评估，随机抽样了13,676 1 km ²对景观进行了次选择，以识别1684个永久性的开放水域湿地景观。应用了一系列简约的景观指标，并在人为干扰水平和自然地区（即草地，帕克兰和北方）之间进行了比较。结果表明，永久性开放水域湿地相对稀少（占我们随机样本总数的12.3％），并且通常只占湿地景观的8％以下。与大型项目开垦产生的永久性开放水域湿地景观相比，研究区中的大多数湿地在永久性上较少，而且在自然方面变化更大，这有可能改变自然界以外的开放水域湿地的分布和规模。干扰水平和自然区域之间的比较在景观结构之间产生统计差异。
