Coloniza？？o natural por espécies nativas e exóticas das encostas degradadas da Serra do Mar

the landslides are inherent events to the dynamics of the serra do mar, in the stretches most declivous. however, some factors of intervention, such as atmospheric pollution, occupation of the base of the mounts, among others, increase the incidence of this event. furthermore, the present study aimed to evaluate the settling dynamics of degraded areas of hillsides, aiming for a restoration. two experimental areas were adopted, in stretches of the serra do mar, next to the baixada santista where parcels of one m2 had been launched, and phytosociological data was obtained. after that, the areas were cleaned and the same parameters of the initial evaluation were registered, monthly, during 1 year. twenty species were found, pertaining to 14 families, in its majority exotic or not-regional native species.
