Impacts of invasive plant species on river systems
David Le Maitre - CSIR Natural Resources and the Environment
This presentation focuses on the impacts of invasive alien plants on the water flows in South Africa based on riparian invasions.
Wattles and eucalypts are mainly invaders of riparian zones where they frequently become dominant and completely exclude native species.
Riparian invaders also alter river sediment dynamics, nutrient fluxes and assimilatory capacity, with significant impacts on ecosystem services.
