Oil sands mining and reclamation cause massive loss of peatland and stored carbon
We quantified the wholesale transformation of the boreal landscape by open-pit oil sands mining in Alberta, Canada to evaluate its effect on carbon storage and sequestration. Contrary to claims madeExpand

Setting reclamation targets and evaluating progress: Submersed aquatic vegetation in natural and post-oil sands mining wetlands in Alberta, Canada
Abstract Oil sands mining disturbs thousands of hectares of boreal landscape, about 65% of which is wetland. Its reclamation will constitute the largest wetland reclamation project in CanadianExpand

The accuracy of land cover-based wetland assessments is influenced by landscape extent
Widespread degradation of wetlands has motivated the development of tools to evaluate wetland condition. The application of field-based tools over large regions can be prohibitively expensive;Expand

Development and testing of an index of biotic integrity based on submersed and floating vegetation and its application to assess reclamation wetlands in Alberta’s oil sands area, Canada
We developed and tested a plant-based index of biological integrity (IBI) and used it to evaluate the existing reclamation wetlands in Alberta’s oil sands mining region. Reclamation plans call forExpand

Community congruence of plants, invertebrates and birds in natural and constructed shallow open-water wetlands: Do we need to monitor multiple assemblages?
Abstract Biomonitoring is a common means of evaluating wetlands. It is based on the premise that the community composition of one taxonomic group is indicative of overall biology and the underlyingExpand

Aquatic macroinvertebrates are poor indicators of agricultural activity in northern prairie pothole wetlands
Abstract The Northern Prairie Pothole Region (NPPR) of Alberta, Canada, contains numerous shallow marshes that serve as important habitat for wildlife and provide essential ecosystem services. ManyExpand

A plant‐based index of biological integrity in permanent marsh wetlands yields consistent scores in dry and wet years
Plant-based assessments can contribute to wetland conservation and management by providing a standardized method to monitor biological communities in relation to human activity. One major challenge,Expand

Megaproject reclamation and climate change
Megaprojects such as oil sands mining require large-scale and long-term closure and reclamation plans. Yet these plans are created and approved without considering future climate and hydrologicalExpand

Freshwater rainbow trout (Oncorhynchus mykiss) farming affects sediment and pore-water chemistry
Marine aquaculture has come under scrutiny, whereas little is known about the nature and extent of the effects of cage aquaculture in freshwater. We describe the development of changes in sedimentExpand

The strength of cross‐taxon congruence in species composition varies with the size of regional species pools and the intensity of human disturbance
Aim Our aims were to determine whether cross-taxon congruence of species composition patterns varies across regions and human disturbance levels and to infer whether these patterns relate to theExpand
