THE NEGATIVE IMPACTS OF CHROMOLAENA ODORATA ON THE ENVIRONMENT
I would like to share with you the little information I gathered on C.odorata species. The C. odorata species originates from South and
The C. odorata consist of a single stem with branches growing in pairs to form auxiliary buds. It produces white flowers that contain small seeds of about 3 to 5mm long every year. As it forms a dense thicket, it reduces the level of biodiversity thereby suppressing the growth of young trees. The seeds of C. odorata species can disperse for long distances with its transport media being wind, water, humans, machinery and vehicles. It has relatively large seeds bank longetivity.
The C. odorata is easily propagated from root fragment, stem and from seeds (King and Robinson, 2006) and it preferably grow in open freely-drained ground area with annual rainfall of more than 1200 mm (King and Robinson, 1997). C. odorata can grow in many different types of soils. It prefers to grow in well-drained soils and can not survive on moist and saline soils. The C. odorata has short juvenile period. The C. odorata may also occur in disturbed areas, agricultural areas, planted forest, and also in riparian zones but can not tolerate shade.

The handpulling method can be used to mitigate the spread of this species, more especially in young plants. Herbicides can also be used in order to kill the mature C. odorata species. Annual burning regimes can effectively controls the invasion of C. odorata. This is because fire would kill the mature plants and prevent new seedling from establishing. Biological control may also be used.
