Gypsum outcrops of southeastern Spain (Almeria) have been highlighted as the most outstanding for the conservation of Iberian gypsum flora by flora rarity and richness, as vascular as cryptogamic plants. However, plant community distribution patterns

Rehabilitation of open-cast gypsum mines is made difficult by the permanent loss of the original soil resource. Soil development can be accelerated by using organic amendments (e.g., MSW compost), which provide both physical (structural) enhancement
