Reclamation Research Program 2000, EKATI Diamond Mine (BHP Billiton, 2000)
18 December 2000Report
This 2000 reclamation research report documents BHP Diamonds' revegetation efforts at the Ekati Diamond Mine, including soil topdressing effectiveness at Fox portal, vegetation establishment in the Panda Diversion Channel, and development of a reclamation registry. After five growing seasons, organic soil topdressing proved most favorable for plant growth, while native-grass cultivars achieved highest cover (39-52%), and Arctic Pendant Grass transplants in the diversion channel showed 60-92% survival rates.
