Bio-Physical Closure Criteria Without Reference Sites: Realistic Targets In Modified Rivers, Melanie L. Blanchette, Mark Lund, Robyn Stoney, Digby Short, Colm Harkin

ECU Publications Post 2013

The use of reference sites for establishing closure criteria in areas disturbed by mining activities is common practice. ‘Reference’ sites are those considered to be largely unimpacted by anthropogenic activity (retaining desirable natural characteristics), and occurring near disturbed sites. Sites are considered rehabilitated when their biophysical condition approximates that of the reference site. However, this approach often creates impossible or unrealistic targets for miners seeking to close rehabilitated lands. For example, reference sites are often limited in availability (or non-existent) due to impacts by other land uses. Further, any available reference sites might not be realistic matches for the rehabilitated ...
