We attended the 2nd PhytoSUDOE (Interreg Project) Stakeholder Workshop held in the Universidade Católica Portuguesa, Porto (Portugal, 17th April 2018). During such workshop, Carlos Garbisu from SMEG gave a talk on “Improvements in soil biodiversity and function after long-term implementation of phytomanagement options”. We focused our presentation on the importance of biodiversity conservation, owing to its potential effects on ecosystem stability (resistance and resilience). The concept of functional redundancy was also discussed. Finally, the fostering of biodiversity under phytomanagement was encouraged.
