The Cullinan Conservancy is actively involved with the control of invader weeds. The SANBI list of declared weeds and alien invader plants is available here. 

This link from Biodiversity Explorer provide more information on the different invader categories as well as pictures of the plants. Please make sure you do not propagate these plants and eradicate them if they are on your property.

Pom Pom Weed

Pom Pom Weed is seriously threatening our grasslands. Please note that you HAVE to ERADICATE Pom Pom on your property by law.  Please think of your neighbours also, your Pom Pom investation is spreading to neighbouring farms.

As in previous years where we find the weeds on a farm we will notify the farmer by email. If no attempt is made to clear the Pom pom plants within 3 weeks, the letter will be forwarded to the Department of Agriculture who will issue a directive.

Cullinan Conservancy has purchased a limited amount of Plenum, and paid-up members can fetch some from Joan (bring your 500ml container).
