Invasive plant species in South Africa: a simple guide

In South Africa, some plants are not native. When these plants spread into wild places and crowd out local plants, they are called invasive. They can harm ecosystems, wildlife, farming, and water supplies.

How they spread
- They grow fast and spread seeds easily.
- Garden plants can escape into the wild.
- They may be carried by wind, water, animals, or people.

Why they matter
- They push out native plants that many animals need for food and shelter.
- They can clog rivers, lakes, and irrigation channels.
- They can reduce crops and grazing land for livestock.

What you can do
- Plant native species in gardens.
- Don't dump garden waste in wild areas.
- If you see a large patch, tell your local municipality or a nature group.
- For small patches, pull them out carefully and dispose of them in trash or compost where allowed.

Common examples you might see
- Lantana camara (lantana)
- Chromolaena odorata (Siam weed)
- Eichhornia crassipes (water hyacinth) in water bodies
- Opuntia ficus-indica (prickly pear cactus)
- Prosopis juliflora (mesquite)

Note: The presence of these plants varies by region. If you're unsure, ask a local conservation group or your municipality.
