The aim of restoration is recompose a new vegetation structure in order to obtain benefits such as the containment of bank erosion, reestablishment of a hydric and nutrient regime, and increase the diversity of species. The present paper evaluated the development of the vegetation introduced as ciliar forest around a mining lagoon through establishing indicators based on the vegetation structure, physic-chemical characteristics of the soil and the water. Results show that the indicators of vegetation, like dying of species and the covering of top were classified as negative factors. Regarding vegetation development, it was considered positive when individuals out of inundation points were analyzed. According to soil indicators, chemical factor pH acid suggests intoxication by aluminum, iron and manganese impeding development of the vegetation in the local. Topographic factor also caused erosion and dying/extinction of species localized in declining points and carried nutrients to the inundation point and finally to the sand mining pool.

Soil color and other morphological features have definite limitations in differentiating Gleyed Gray Wooded from related Gleysolic soils of similar morphology. Iron and manganese data could provide guides for their separation. Oxalate-extractable to dithionite-extractable iron ratios differed considerably in or below the B horizon. The ratios for the BC horizons were 0.09 for an Orthic Gray Wooded, 0.29 to 0.45 for three Gleyed Orthic Gray Wooded and 0.55 to 0.93 for three Gleysolic soils. Dithionite-extractable iron to clay ratios were relatively constant in the Orthic Gray Wooded, a slight minimum occurred in the Bt horizons of the Gleyed Orthic Gray Wooded soils, and a maximum occurred in AB or B horizons of the Humic Eluviated Gleysols and the Fera Humic Gleysol. Total manganese distribution could aid in the separation of these soils; the maximum accumulation of manganese occurred in the Ae and Bt horizons of the Orthic Gray Wooded, in the Bt horizons of the Gleyed Orthic Gray Wooded, and in the C horizons of the associated Gleysolic soils. Aluminum distribution (dithionite- and oxalate-extractable) did not differ among these soils, indicating that it was not affected by differences in drainage regime.
