Objectif(s): To determine appropriate methods to restore disturbed sites at Diavik Diamond Mine to productive and sustainable tundra communities following mine closure.
Description du projet: The overall research goal is to determine appropriate methods to restore disturbed sites at Diavik Diamond Mine to productive and sustainable tundra communities following mine closure. There are three main research areas 1) building suitable reclamation substrates for plant establishment and growth, 2) methods of collection and propagation of locally common native plant and lichen species, and 3) longer term monitoring of research sites to assess reclamation success over time. Research plots were established in 2014 on the old magazine store area at Diavik to test the effects of substrate, microsite and organic matter addition on plant establishment and growth. Substrates include processed kimberlite, lake sediment and crushed rock. Native grass and forb cultivars will be sown. Surface soil samples will be collected and analyzed at a laboratory. Data loggers will be installed to monitor soil water content and tempera... Plus de résultats
