HOW TO ERADICATE ALIEN TREES

Invasive alien species occur everywhere and affect everyone. They spread faster and grow stronger and are more competitive than indigenous species and have no natural enemies. They invade rapidly and become a threat to the ecosystems and natural habitats. They are as such the biggest single threat to our plant and animal diversity, as well as our water resources. Some are illegal to have on your property.

It is our duty to strive to eradicate them at every opportunity; however some attempts at eradication have failed and made the problem worse, e. G. Look at the land on the N2 side of the causeway on the Island. If the aliens are not cut and treated with authorised herbicide, they grow back even stronger (coppice).

So here are a few simple steps on how to get rid of alien trees:

 

1.   IDENTIFY

Typically the ‘baddies’ you will be looking for

·         Port Jackson Willow (Acacia Saligna)

·         Rooikrans (Acacia Cyclops)

·         Inkbessie (Cestrum Laevigatum)

·         Madeira Vine (Anredera Cordifolia)

 

2.   CUT OR PULL OUT (if a seedling)

Cut a clean cut as low down as possible

 

 

 

 

 

 

3.   SPRAY

Use only authorised herbicide. Spray immediately, not a day later. Note the blue dye in the spray for easy identification.

 

4.   REMOVE CUT TREES

Do not clutter the veld with dead trees.

 

That is as simple as it gets. If you need advice in alien eradication, herbicide use and availability etc please contact the Sedgefield Island Conservancy:
