The network of multi-species tropical forest plantation plots includes 5 sites in Brazil : 3 experiments with two associated species, Eucalyptus/Acacia model * 2 sites on the Itatinga Experimental Station (USP/ESALQ), State of São Paulo *1 site at the Sinop experimental station (Embrapa), State of Mato grosso 2 experiments with more than two associated species, native species model of the Mata Atlântica *1 site on the Itatinga Experimental Station (USP/ESALQ), State of São Paulo *1 site on the Anhembi Experimental Station (USP/ESALQ), State of São Paulo The Multispecies tropical fORest PlantatIon NEtwork (MORPhINE) focuses on the biological mechanisms and ecological interactions that condition the relationship between biodiversity and forest ecosystem functioning. The Itatinga (SP) site 200 km west of São Paulo and the Anhembi (SP) site 80 km north of Itatinga are representative of sub-tropical conditions. The Sinops (MT) site, 2000 km from São Paulo in central Brazil, has tropical conditions. The size of the experiments varies according to the sites: 5.2 ha and 2.6 ha for eucalyptus/acacia experiments (Itatinga and Sinops), 6 ha for native species experiments (Itatinga), 2.6 ha for native species experiments (Anhembi). Various levels of mixed-species forest are tested: two species with Eucalyptus grandis and Acacia mangium; a gradient of species native to the Mata Atlântica (Itatinga site); and 20, 60 and 120 species native to the Mata Atlântica (Anhembi site). In addition to mixture effects, other practices are studied at the different sites: fertilisation, planting density and spacing between species, the proportion of species in the stand, reduced rainfall, ...
