Exploring the mechanism of submerged invasions in South Africa

South Africa’s long history with floating invasive macrophytes has led to a large body of research into this field, whereas submerged invasive macrophyte studies are far fewer.
This study aims to understand the driving mechanisms underlying dense water weed (Egeria densa) invasions in South Africa, by investigating the ability of this species as a resource competitor against submerged native species, helping to predict where it is likely to establish and to what degree of success.
This will enable informed management decisions, including the importation and potential release of the leaf mining fly (Hydrellia sp.) a promising biological control agent.
