In order to characterize the environment where plant species have better adaptation, one way is to associate species abundance and distribution with environmental parameters. To do this, we worked in a tropical forest fragment, with point-quarter sampling. The sampling points were parameterized by topographic, hydrographic and soil components, using slope, aspect, distance and water body altitude differences, and fertility and grain size parameters. With canonical correlation analysis and principal component we could detect preferences of some species for water supply, which in turn correlates with some grain size and fertility parameters. The environmental variation related to species abundance and distribution allowed the indication, especially associated with water characteristics, of species for ecological restoration.
