Technogenic Ecological Sequences in Tailing Pond from Căpușu Mare, Built between 1975-1981

In Romania, all actions related to mining management are found in “Strategy of the mining industry for 2012-2035”. Today, numerous tailing ponds have remained outside rehabilitation operations, and they are becoming more natural, as is the case of the tailing pond in Capusu Mare. The vegetation study was conducted in 2015, at the tailing pond III in Căpușu Mare that was operational between 1975-1981. The following phytopopulation and phytocenotic indices were calculated: presence, frequency, class of presence, abundance-dominance and average abundance-dominance (ADm) of species. Floral studies show the presence of 40 plant species. The wood species with the highest mean dominant abundance are Hippophäe rhamnoides (14.78%) and Salix alba (10.55%), and of herbaceous species stands Phragmites communis with 7.49%. After 34 years from the heap closure, the degree of vegetation coverage is 77%. Wood species occupy about 32% of the heap surface.
