Figure pH values of unamended and amended soils by zones and treatments with standard errors. Unamended soils of all zones are very acidic pH. Highlights Post-disturbance recovery of vegetation and soil is unlikely in xeric regions.
We quantified recovery of semi-arid old fields in below-average rainfall years. Vegetation showed some resilience but remained different to uncultivated sites. Soils largely recovered and did not drive the main patterns in the vegetation. Seed availability may delay recovery rather than environment or Cited by: Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal mines.
Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually within rocks.

Three levels of vegetation restoration in Giant Forest Village were tested, in order of increasing human intervention: 1) Restore Soil Only. Actions are limited to regrading to restore natural landforms, amending soils in highly disturbed sites, cultivating, and mulching with litter and duff or wood chips.
This is considered the minimal treatment. Abstract. Humans have disturbed desert soils and vegetation since man began to occupy arid lands. These disturbances were usually restricted to areas adjacent to towns or villages and resulted from tillage, mining, or access trails and by: practices, and drainage conditions are involved in sa-linity and alkali establishing an irrigation project, soils that are initially saline require the removal of the excess salts and may require chemical amend-ments in addition to an adequate supplv of irrigation water.
On. In acid-sensitive regions, acidic deposition alters soils, stresses forest vegetation, acidifies freshwaters, and harms fish and other aquatic life. These effects can interfere with important ecosystem functions and services, such as forest diversity and productivity and water quality and fisheries.
