Mediterranean grassland succession as an indicator of changes in ecosystem biodiversity and functionality

Abstract The abandonment of agricultural lands triggers a secondary succession plant species which implies important changes in soil quality. Annual Mediterranean grasslands are known to be persistent on abandoned agriculture the western Mediterranean. We used taxonomic and functional approaches determine role as an indicator ecosystem biodiversity functionality. tested hypothesis that suitable model for monitoring fertility succession. Soil vegetation features 21 permanent plots were monitored 2016 2020. Numerical classifications based floristic composition showed two different communities independently sampling year: early-stage first post-abandonment decade late-stage after decade. Generalized linear redundancy analysis also revealed differences growth forms, traits functionality between communities. Late-stage was characterized by enriched bryophyte coverage impoverishment hemicryptophytes latex segregators growing soils with higher hydrolase enzyme activity TOC content compared grassland. Our results suggest annual siliceous denoting mature-stage succession, floristically symbiont Ascomycota, Tuberaria guttata , high cover, worthy recognition conservation.
