ABSTRACT: Swamp Forests occur in permanently wet soils, with
specific ecosystem which contributes to the conservation of biodiversity and
water resources. However, there are many gaps in knowledge about the
restoration of these forests. The present study was conducted in a degraded wetland
in the town of Mineiros do Tietê, located in the state of S?o Paulo, Brazil, in
order to test the efficiency of four methods for restoring a Swamp Forest
(small mound, acclimated seedling, dry season and conventional tillage), using
six forest tree species typical of this type of forest: Calophyllum brasiliense Cambess., Citharexylon myrianthum Cham., Cedrela odorata L., Tapirira guianensis Aubl., Ficus
insipida Willd. and Croton urucurana Baill.
The least favorable methods for all plant species were: conventional and soil
pit tillageindry seasons. Analyzing the plant species individually, the best
results in descending order were: Croton
urucurana Baill. (acclimated seedling tillage in dry season), followed by Calophyllum brasiliense Cambess. (insmall
mounds), Citharexylon mirianthum Cham. (with acclimated seedlings), Ficus
insipida Willd. and Tapirira
guianensis Aubl. (insmall mounds). Cedrela
odorata L. presented low performance in all conditions, probably because it
suffered the Hypsipyla grandella Zeller. The results have been successful for the establishment of Swamp Forest
restoration strategies.
