Predicting which introduced plants and animals are likely to become invasive is a key challenge for invasion biology. To help make these predictions, scientists use models that can predict the potential spread of introduced species.
Protected areas (PAs) are a key intervention for conserving biodiversity and ecosystem services. A major challenge for PAs is the control of invasive alien plants that spread into PAs from surrounding areas such as forestry plantations.
It may no longer make economic or environmental sense to pursue forestry endeavours using conifers in the Western Cape. If local plantations are to be maintained, invasive pine trees will continue to spread, the Cape’s water supply will continue to dwindle and the unique natural diversity of the fynbos region will be changed forever.
