Revegetation of mine tailings often relies on a thin soil cover to support vegetation growth. However, these tailings can be chemically and physically hostile to plants—especially when the depth of the cover soil is limited due to resource constraints. Poor vegetation establishment in these areas increases erosion risk and presents ongoing environmental and regulatory challenges, so when revegetation persistently fails, an in depth investigation is required.

Verterra has specific expertise and prior experience in detailed spatial and quantitative impact assessment and analysis of the effect of subsidence.  This project, carried out for Anglo American’s Grosvenor Coal Mine, assessed the impact of subsidence on native vegetation.
