Diversity of invasive alien species of Jammu district (Jammu and Kashmir).

ABSTRACT

The present study deals with comprehensive list of Invasive alien plants of Indian Himalayan Region with background information on family, habit and nativity. A total of 60 invasive alien species under 51 genera, belonging to 33families have been recorded. Among these, the dicotyledons represent by 28families and 52 species; monocotyledons represent by 5 families and 8 species. The analysis of invasive species reveals that most species have been introduced unintentionally through trade while only 11species intentionally introduced. Most of the species are of American origin. While in life form analysis, the herbs (45 species) are dominant, followed by shrubs (6 species), Grass (3 species), Trees, sedges and climbers (2 species each). Most of the invasive species are annual habit (57%). A better planning is needed for early detection to control and reporting of infestations of spread of new and naturalized weeds to be monitored.
