Moreover, gold mining destroyed massive tracts of vegetation. Woody species encountered at plot level decreased from artisanal gold mined to unmined sites (P ≤ ). Moreover, dead trees and exposed tree roots were higher in mined than the unmined areas (P ≤ ). This discouraged regeneration and recruitment of woody vegetation.
