Experimental recultivation plantations were established in 2001-2003 in three areas allocated depending on the degree of exposure to industrial emissions and the state of woody vegetation in the vicinity of the city of Norilsk industrial region. The first object was the control zone of moderate disturbance, where the vegetation is mostly in normal state - east of the town of Talnakh (Listvyanka river area), the second object is located in zone of strong disturbance (Nalednaya river area, 1 km south of the town of Oganer), and third object of the experimental plantations was established in zone of very strong disturbance of vegetation - at Ergalakh river area (10 km south-east of the city of Norilsk). Experimental plantations were created by planting natural plants (wildings) of Picea obovata L., Larix sibirica L., Rosa acicularis L., Junipeus sibirica L., and different species of willow cuttings using different farming techniques to grow them. In 2008, studies were carried out by state (survival, safety, growth rates) of the created recultivation plantations. The studies have revealed species resistant to industrial emissions in Norilsk region. It has been discovered that survival rates and safety of willow plantings created by cuttings depends on planting technology and site properties. The greatest safety and resistance to industrial emissions were woolly willow Salix lanata L. and Salix hastata L.
