Flora & Invasive Plants

Our aim is to promote the planting of indigenous plants and to eradicate foreign invasive plants. Our Conservancy makes herbicides available to combat invasive plants – contact your committee in this regard.

The conservancy is rich in natural flora such as varieties of amaryllis, crinums, arums, haemanthus, brunsvigias and Natal scilla. Some of these larger, ever popular “muti” plants have been sadly denuded for medical use. Your gardens would be greatly enhanced by propagating them. Plants are often available from indigenous nurseries in our area and from the Botanical Gardens in Pietermaritzburg. Again, good veld burning practices tend to preserve and enhance indigenous flora.

To identify wildflowers in our area – photos included, visit our neighbouring Dargle Conservancy on: http://www.dargleconservancy.org.za/wildflowerarchive/wildflowers.php

The natural forest patches still contain more than 60 species of indigenous trees including sagewoods(Buddleja sp.), yellowwoods (Podocarpuslatifolius, Podocarpusfalcatus, Podocarpushenkelii), Cape Chestnut (Calodendrumcapense), White Stinkwood (Celtis africanus),Sneezewood(Ptaeroxylonobliquum) and Wild Peach (Kiggelaria Africana).

To protect the remaining forest:

  • Use good grass burning practices and never allow the fire nearer than 20m from the verges – read this one pager by clicking here;
  • Do not allow cattle to enter the forest;
  • Do not disturb the forest margin which protects from wind and frost and
  • Discourage bark-stripping for “muti” purposes.

 

Invasive plants are removed mechanically and/or with herbicides. The biggest challenge is to continue to fight the alien plants – they tend to come back. Visit this site for general information in eradicating invasive alien plants. Click Here

Bugweed and American bramble are category 1 plants that must be controlled on land by all land users. Property may not be transferred, subdivided or changed in use, unless listed plants are controlled. “Controlled” generally means eradicated.
