Gundla Brahmeswaram wildlife sanctuary is invaded by many alien plant taxa which interfere with native biodiversity. It is highly important to explore the concerned problems caused by the intrusion of invasive plant taxa and to mitigate the impact on native diversity. To achieve this, the present study has taken up for the first of its kind and listed the 102 plant species representing 84 genera and 32 families. Of these, 54 plant species have their origin in Tropical America followed by many other parts of the world. The predominant family was Asteraceae with 23 plant species, followed by Fabaceae (12), Amaranthaceae (10), Convolvulaceae (7), Malvaceae (6), Euphorbiaceae, Lamiaceae, Solanaceae (4 each), Acanthaceae, Poaceae (3 each), Apocynaceae, Asparagaceae, Cleomaceae and Cuscutaceae (2 each). 18 families were contributed with single species each. The abundant and most serious invasive species were recognized in the sanctuary, namely, Hyptis suaveolens, Lantana camara, Senna uniflora, Parthenium hysterophorus, Ageratum conyzoides, Waltheria indica, Chromolaena odorata, Mimosa pudica and Prosopis juliflora, Cuscuta species. The present study calls for a standard, unique planning in early identification, spreading and infestation of invasive weeds and involve taxonomists, forest managers, ecologists to control and monitor.
