# The Centre for Biological Control has been appointed by Rand Water to manage invasive plants on the Vaal River Barrage reservoir. Efforts target water hyacinth and water lettuce which are highly invasive species exacerbated by nutrient-rich effluent, warm temperatures, and reduced water flow. The organisation’s head, Julie Coetzee, says the aims is to maintain plant coverage below one-hectare using biocontrol agents, physical removal, and chemical methods. She says long-term efforts include community partnerships and rearing facilities for specialised biocontrol agents.
