Survey for potential tree species for vegetation of iron ore mine wastelands of Goa

Abstract

Vegetation survey of various iron ore mine reject dumps was carried out. The paper enlists 64 tree species belonging to 52 genera distributed among 27 families. The list includes both naturally occurring and cultivated tree species. The former species in particular have survived and grown over the years on the once disturbed and degraded mine lands and hence show a tremendous potential in revegetation programmes of iron ore mine wastelands in the state. The families recorded are Mimosaceae (7 spp.), Apocynaceae (2 spp.), Ulmaceae (1 sp.), Anacardiaceae (4 spp.), Myrtaceae (3 spp.), Casuarinaceae (1 sp.), Rhamnaceae (2 spp.), Caesalpiniaceae (6 spp.), Bignoniaceae (1 sp.), Euphorbiaceae (4 spp.), Moraceae (5 spp.), Fabaceae (5 spp.), Annonaceae (3 spp.), Bombacaceae (1 sp.), Rutaceae (1 sp.), Arecaceae (2 spp.), Combretaceae (4 spp.), Verbenaceae (2 spp.), Flacourtiaceae (1 sp.), Clusiaceae {1 sp.), Malvaceae (1 sp.), Sterculiaceae (2 spp.), Lecythidaceae (1 sp.), Rubiaceae (1 sp.), Sapotaceae (1 sp.), Loganiaceae (1 sp.) and Musaceae (1 sp.) with the total number of species given in the brackets.
