Phytosociology of invasive alien therophytic flora of Peddagattu, the proposed site for uranium mining in Nalgonda district, Telangana, India.

Abstract

ABSTRACT:The present investigation reflects the findings of invasive alien species and phytosociological attributes at Peddagattu (Lambapur), Nalgonda district, Telangana, India. Phytosociology studies on Invasive alien species were collected during 2010-2012. Of 30 species of taxa are belonging to 29 genera and 17 families. Compositae is the most dominant family representing   with 6 species (20%) followed by Malvaceae 4 species (13%), Solanaceae 3 species (10%), Amaranthaceae  and Leguminaceae with 2 species (7% each). About 60% of these alien species were introduced from Tropical America followed by Tropical Africa (13%), and Trop. C. America (7%). Among the species, Tridax procumbens shows the highest IVI value (12.94) and followed by Cleome viscose (7.12), Waltheria indica (6.13) and Parthenium hysterophorus (5.57) and Typha angustata (5.22).
