Diversity, Distribution and Uses of Invasive Alien Angiosperms of Rampur District (U.P.), India

Abstract

Invasive alien angiosperms have become an environmental concern in India. A survey of invasive alien angiosperms of Rampur district was made. The data revealed that both aquatic and terrestrial invasive alien angiosperms are becoming threat to the native flora as they reproduce rapidly and crowding out native species. In the present paper 33 invasive alien angiosperms belonging to 23 families are recorded. The contribution of tropical America (70 %) including South America (15 %) is noteworthy. From the interaction with local people and literature survey it was found that invasive alien angiosperms were used as medicine (20), fodder (8), ornamental (8), vegetable (2) and fibre (1).
