The status of alien invasive species in Bangladesh and their impact on the ecosystems.
Introduction of alien invasive species of flora and fauna were deliberate in Bangladesh, primarily, to increase productivity to support the needs of 130 million people in area of only 147 000 sq km. However, some of them were introduced for decorative or ornamental purposes. Almost all of the alien invasive species in Bangladesh possess the characteristics of high growth rate, i.e. high turnover rate.
