An invasive species is a species which is non- native , usually dominant, highly competitive with native species can cause damage to plants, animals and livelihoods of humans (ISAC 2006)
Many invasive species were introduced intentionally or by accident. Some species were used with good intentions such as to restore degraded lands but turned out to be problematic. The Water Hyacinth also scientifically known as Eichhornia crassipes is an invasive plant species on the Volta lake(Appenteng, 2014). The plant is originally from Amazonas, Brazil and was introduced to Africa because of it ornamental purpose. Water Hyacinth grows fast and forms a dense cover on the surface of water.These characteristics of the plants hinders transportation of boats, serves as breeding grounds for mosquitoes and blocks channels for irrigation( FAO 2002). Invasive species cost lots of money to control and can affect the livelihood of local people.
