Abstract
A survey was carried out from 2005 to 2010 to invent the invasive alien plant species and their economic uses in urban and adjoining rural areas of Uttarpara, Hooghly district, West Bengal. The study revealed the occurrence of 103 alien angiospermic plant species under 32 families, of which four families (Araceae, Poaceae, Cyperaceae, Pontederiaceae) are monocots. Dicot family Fabaceae dominated with 20 plant species, followed by Asteraceae with 17, Amaranthaceae with 8, Solanaceae with 7, Euphorbiaceae with 5, and then other families. Rise in number of alien species was evidenced in year-wise quadrat studies, screening 11 most invasive species namely Parthenium hysterophorus, Eupatorium odoratum, Ageratum conyzoides, A. haustonianum, Chromolaena odorata, Cassia sophera, Leucaena leucocephala, Alternanthera sessilis, Amaranthus spinosus, Lantana camara and tree, Trema orientralis distributed within Asteraceae (5 taxa), Fabaceae (2 taxa), Amaranthaceae (2 taxa), Verbenaceae (1 taxon) and Ulmaceae (1 taxon). Remarkably, the alien species have been used in diverse economic and commercial purposes by local village folks, showing the use of nearly 49% plants in local health-care systems as herbal products.
