Mississippi River water hyacinth, water lettuce and parrot feather, oh my!

Thousands of water lettuce and water hyacinth plants were found in Pool 5 in 2011 and by 2012 the populations exploded into the tens of thousands.

Two weed harvesters and two transport barges for harvesting water weeds were on Wednesday commissioned at Kpong in the Eastern Region to assist in reducing the spread of invasive water plants.

The commissioning formed part of the Environmental Protection Agency (EPA)’s initiative dubbed “Ghana Integrated Management of Invasive Aquatic Weeds Project” which is funded by the African Development Bank (AfDB).
