ИСТИНА

The nickel-processing industry has contributed significantly to environmental damage and deterioration both in Sudbury, Canada and the Kola Peninsula, Russia. The internationally recognized Sudbury Protocol for technogenic barren landscape restoration has evolved over 40 years since 1978 from regreening activities that involved application of dolomitic limestone, fertilizer, seeding of agricultural grasses, legumes and planting of tree seedling to a more complete biodiverse restoration strategy. The effectiveness and success of landscape rehabilitation programs initiated in 2003-2004 in the Kola Peninsula is also largely dependent on the continual decreases in pollutant loading onto the landscapes, on continuing improvements in the physico-chemical conditions of regional soils, and on the effectiveness and suitability of the continuously evolving land remediation technologies.
