Long-leafed acacia (Acacia longifolia) is one of the many species of invasive alien trees that have invaded riparian zones in the Western Cape. Successful eradication of such species should be guided by context-specific planning strategies to ensure that specific challenges are mitigated, particularly in areas where resources are limited.

Understanding the past, present, and future to guide restoration

A new study by Stellenbosch University researchers shows that a lack of funding, poor communication among stakeholders and inadequate knowledge are the major barriers to successful restoration of riparian zones in the Global South.

The number of (A) invasive alien species across broad taxonomic and life-form groupings for which ecological impacts have been quantified in South Africa; and (B) the number of published studies on each group.

Impacts of invasive alien species in South Africa reviewed

A review of the peer-reviewed literature was undertaken at the Centre for Invasion Biology (C·I·B) to determine the level of understanding of the impacts of invasions of all taxonomic groups in all natural and semi-natural ecosystems in South Africa.

Australian acacias are genetically highly diverse across the globe

Australian acacias are some of the world’s worst invasive plants and their success has been heavily shaped through their usage by humans for various purposes. C·I·B research members Prof Jaco Le Roux, Prof Dave Richardson and Prof John Wilson, together with colleagues from the University of Lisbon, published a meta-analysis on the genetic diversity of 37 Australian Acacia species.
