The effect of mechanical clearing and litter removal on control of Sydney golden wattlewas studied in areas of Portugal that had been invaded for either long or short periods. The plantspecies that emerged and soil parameters were monitored to assess the recovery potential and thesoil status of these areas after Sydney golden wattle control. More plant species emerged in the plotswhere mechanical control in combination with litter removal was applied than in nontreated plots orin plots where mechanical control alone was used. More plant species emerged in the recently invadedareas than in those that had been invaded for a long time. More Sydney golden wattle seedlingswere found in the long-invaded area than in the recently invaded one. Total litter, nitrogen and carboncontent, and -glucosaminidase activity were higher in the soil of the long-invaded compared withthe recently invaded areas. Regarding the efficacy of the methods used to remove Sydney goldenwattle, sprouting was not observed 10 mo after cutting the trees in both areas, although this was notthe case in other parallel studies.
