Impaired Wetlands in a Damaged Landscape: The Legacy of by Kevin P. Timoney

By Kevin P. Timoney

This paintings is a systematic monograph that examines the plant life and plants of ordinary mineral wetlands compared to mineral wetlands laid low with bitumen exploitation. The paintings is of wide relevance simply because (a) wetland loss and degradation is a world challenge; (b) the ongoing international raise in fossil gas exploitation is leading to frequent harm; and (c) bitumen (tar sands, oil sands) exploitation is a quickly becoming and damaging set of actions. The middle of the paintings is a meta-analysis of 417 plants plots. Analyses of swap over the years and chemical and actual attributes of water and soil are provided for the subset of plots with adequate facts. the aim of the paintings is to illustrate that: (1) There are marked variations among average and industrially-affected wetlands. (2) Industrially-affected mineral wetlands range from usual wetlands of their crops assemblages, their depressed crops and species variety, and their abundance of unique weeds. (3) profitable post-bitumen mining wetland reclamation has no longer been comprehensive and should now not be possible in the foreseeable destiny given the ecological and actual stipulations of the commercial wetlands, present reclamation practices, and lax regulatory criteria. In regard to govt coverage and commercial practices, it reveals that they're liable for reclamation failure on a grand scale.

OSREF wetlands are not natural baseline wetlands; they are disturbed to varying degrees by human activities; some OSREF wetlands are reclaimed (constructed). Wetland age data for 38 OSPA reclaimed plots and 22 OSREF reclaimed plots were provided by Rooney (pers. , June 2012). Reclamation wetlands ranged in age from 3 to 29 years with a mean age of 14 years (Rooney and Bayley 2011b). AG wetlands were differentiated from REF wetlands if agricultural activities such as crops, grazing, or haying were detected within 100 m of the boundary of the wetland (Rooney, pers.

Representatives at Shell and Suncor concluded that neither company possesses the vegetation plot data, nor were they able to procure those data from the original consultants. An attempt by the author to procure the vegetation data directly from the consultants was also unsuccessful.
