The growth of our native Sugarbush (Protea repens) is not negatively affected by the legacy of altered soil chemistry after the clearing of invasive Port Jackson (Acacia saligna).
The soil legacy effects of invasive nitrogen fixing woody species can present several barriers to the restoration of native plant communities. This was the finding of a recent review paper by C·I·B PhD student, Mlungele Nsikani, and C·I·B Core Team Members, Brian van Wilgen and Mirijam Gaertner, in the journal Restoration Ecology.
Native areas that are invaded by the invasive alien tree Port Jackson can experience soil legacies for up to 10 years after its removal. This was the finding of a recent study by a group of C·I·B researchers, led by C·I·B PhD student, Mlungele Nsikani.
