Gallery forests are plant formations characteristic of rivers and water body margins with species highly tolerant or resistant to an excess of water in the soil. They form an important habitat for terrestrial fauna and serve as a food source for aquatic fauna. The floristic composition is variable and influenced by the surrounding plant formations. They are distinct from forest formations which occur on drier lands from their initial stages up to their final or climax stage. Generally the more mature the forest higher is the frequency of species from adjacent formations. The degree and duration of flooding as well as soil fertility, both of which are conditioned by local germophological and climatic factors, also have primordial importance in distinguishing the gallery forests from the forest communities around them. It is well recognized their strategic ecological role in water protection; as a shelter for associated fauna; in biodiversity conservation; in the contention of erosive processes; in macroclimate regulation and forming "ecological corridors" which help maintain contact between fragments of preserved natural forests. In spite of the intensive forest clearing in Brazil in last decades the necessity of recovering areas formerly degraded by anthropic action is not yet well recognized. The is little available knowledge about seed technology and plant production of native species and even about adequate models of reforestation using these species in a self-sustainable way. In the present lecture we will try to emphasize the importance of these types of studies for biodiversity conservation, using as a reference the scientific research developed in last years which included considerations about secondadry succession in models applied to restoration of degraded gallery forest areas.
