Abstract: Mining activities destruct biodiversity in Wazo hill, quarry. The Tanzania Portland Cement Company has revegetated the mined quarry sites for remedy of destructed biodiversity. In order to test the impact of revegetation as means of restoring quarried sites, butterflies were used to determine the effect of restoration by examining their diversity and abundance. Sweep nets and butterfly traps were used for sampling in the revegetated and un-mined sites. However the difference in abundance and diversity between the two sites was statistically insignificant. We concluded that, revegetation has potential to restore the biodiversity by bringing back the species which were lost during mining activities. This suggested that, mined areas should be ecologically restored for rejuvenation of deteriorated ecosystem.
