CIB researchers develop an innovative protocol to map priority areas for detecting new and expanding polyphagous shot hole borer (PSHB) infestations in urban areas.
The potential economic impact of the polyphagous shot hole borer in South Africa amounts to R275 billion over the next ten years if nothing is done to stem the tide. This estimate is the result of a study conducted by economists and ecologists at the Stellenbosch University (SU) and the University of Pretoria (UP).
Urban areas are foci for the introduction of alien species and very often act as launching sites for invasions into natural ecosystems that adjoin urban ecosystems. Until very recently, the study of biological invasions has focused on developing concepts and frameworks mainly for (semi)natural ecosystems.
