SponsorsSupport for this research was provided by the Ministry of Science, Innovation and Universities of Spain through FEDER funds (RESCLICONT project - CGL2016-80981-R). A. Peñalver-Alcalá was hired by this project and received a grant from the Technical University of Cartagena for a short stay at the University of Aveiro. We much appreciate the help of Héctor M. Conesa and Irene Sánchez during field and laboratory work. We thank to the technicians of the SAIT-UPCT for their laboratory and analytical assessments. This work is dedicated to memory of our friend and master, Professor Dr. Mariano Simón Torres, one of the best ever Spanish pedologist, who sadly passed away in April 2019.

Soil biological activity
This work studies a set of soil indicators (physical, physico-chemical and biological), evaluated under field and laboratory conditions, in different stages of spontaneous vegetation colonization in abandoned metal(loid) mine tailings from Mediterranean semiarid areas. The results provide evidence about the interest of spontaneous colonization by native vegetation for the phytomanagement of abandoned metal(loid) mine tailings in terms of providing ecosystem functions. Bare soils (B), small groups of pine trees (P), scattered pine trees with shrubs and herbs under the canopy (P+S), and dense patches of pine trees with shrubs and herbs under the canopy (DP+S) were studied inside mine tailings abandoned ≈40 years ago. Besides, pine forests next (FN) and away (FA) from the tailings were also studied. Pioneer and nurse plants were mainly found inside the tailings, although ecological indexes in P+S and DP+S were similar to FN and FA. Pedogenesis evidences such as structure development and ...
