In Southwestern Europe, studies have showed that Eucalyptus plantations (mainly devoted to paper pulp production, although bioenergy production importance is increasing; DNFF, 2010) have direct and indirect effects upon wildlife: while supporting lower bird's abundance and diversity than native ecosystems (Calviño-Cancela, 2013; Pina, 1989), Eucalyptus plantations affect macroinvertebrate communities of streams that cross plantations, decreasing its abundance and diversity due to alterations on the physic-chemical characteristics of streams,associated for example with leaf and bark litter fall and decomposition differences (Abelho and Graça,1996).
