Mountain roads as conduits for ongoing exotic species expansion

A study by Jesse Kalwij, former C∙I∙B MSc student, Sophia Turner, and C∙I∙B Core Team member, Karen Esler, shows that human activities are the primary cause of exotic species introduction and expansion up the Sani Pass, as well as from the disturbed road verges into the adjacent natural area.

Remote sensing distinguishes species of Tamarix

Remotely-sensed spectral data enable the identification of native, exotic and hybrid Tamarix taxa found in South Africa. This was the finding of a research team including Solomon Tesfamichael (University of Johannesburg) and C·I·B Core Team member, Prof Marcus Byrne.

Does “not in my backyard” hinder invasive species management?

A new study, co-authored by C∙I∙B former PhD student Giovanni Vimercati and C∙I∙B Steering Committee member Dr Piero Genovesi, investigated how and under which circumstances restricted access to private areas limits invasive species management.

Understanding Parthenium invasions: the role of stocking rates in savannas

A recent study by former C·I·B PhD student Dr Blair Cowie and C·I·B Core Team member Prof Marcus Byrne investigated the invasion dynamics of Parthenium hysterophorus in Lowveld savanna reserves with differing stocking rates.

Impacts of alien acacias assessed in a standardised framework

A study by former C·I·B Hons student, Cally Jansen and C·I·B Core Team Member, Dr Sabrina Kumschick used acacias introduced to South Africa as a case study to compare expert assessments with evidence-based impact assessments.
