Abstract

Engineered covers (ET covers) constructed from available materials from the mining process (inert waste rock and topsoil) are widely used In semi-arid to arid environments to restore vegetation on stable and environmentally safe landforms. This thesis examined the functional relationships between soil depth and plant performance, and in particular the effect of soil depth on plant water availability as Influenced by species-specific root distributions and water use strategies. Results emphasise the Importance of understanding the ecophyslology of plants on mined lands, to Improve the restoration success of revegetated disturbed sites in arid to seasonally dry systems.
