During strip mining, one type of surface mining, workers remove the layer of topsoil along with excess soil and rock that overlies caches of minerals near the surface. Once workers finish mining, they usually lay down nutrient-poor soil, called overburden, instead of nutrient-rich topsoil that is more difficult to store during the lengthy mining process, according to Chris Barton of the Appalachian Regional Reforestation Initiative. The overburden soil is also highly acidic, at a pH of 2 or 3, and so doesn't support many trees, bushes or other flora.
