Cryptostegia madagascariensis is a fast-growing invasive woody vine. Originally native to north-western Madagascar, 0t has become widely distributed in India, Kenya, Brazil, Hawaii, Australia and the West Indies. Plants can begin to reproduce after about 200 days and they can produce large amount of seeds which are rapidly dispersed by wind, floodwaters, or stuck to the fur of animals. Seeds can remain viable up to one year and studies have reported germination rates ranging from 90 to 95%. The plant has the ability to quickly spread along water courses, coastal forests, pastures, forest edges, and disturbed areas. It can form dense impenetrable thickets by climbing up trees and covering them, and may also displace and out-compete native vegetation[
