Abstract

In order to determine the degree of ecological damage inflicted as a result of mining operations around the Gothic area, three tailings piles were identified in Gothic and Crested Butte and an observational study of plant species on and around them carried out. It was found that both total numbers of species on our observed plots and total numbers of individual plants increased significantly with increasing distance from the tailings centrepoint, as well as the Simpson and Shannon indices derived from those numbers (P < .0001), indicating that revegetation has largely failed to occur on these tailings—despite a century or more of elapsed time since their deposition.
