Research has found that at least seven species of natural plants in wetlands need to be protected because they are able to clean and remove heavy metals (pollutants) from wetlands water and soil.

The findings also indicate that the plants were found to have the capability to fix nutrients in soil and can be turned into organic manure that has the same fertile capacity as that of manufactured fertilisers.

The study was carried out by Dr Elias Bizuru, a biodiversity conservation researcher and director of research, innovation, and post graduate studies at University of Rwanda’s College of Science and Technology. It was presented Thursday during the sixth annual research conference by the Institute of Policy Analysis (IPAR) themed, ‘Secure biodiversity and ensure management of natural resources toward sustainable development’.
