Johannesburg City Parks and Zoo launches the National Invasive Species Week in Roodeport on 11 October, 2016.
National Invasive Species Week is an awareness and action programme that aims to protect the environment, agriculture and other industries from the threats of invasive plants.
The City Park’s key message for this year’s Invasive Species Week celebration says “Don’t lose water or natural resources to alien invasive species!”
The public is encouraged to remove any invasive plants that grow on or near watercourses as they take up a lot of water.
Some of the water invaders in South Africa were introduced as ornamentals. They have now successively spread to the environment causing a negative transformation on our water bodies.
Aquatic invasive alien plants invade wetlands, rivers, dams and estuaries, causing problems such as oxygen deficiencies in the water, dense biomass that block pump inlets, restrictions to the use of boats for fishing and recreation and reduced flow of water in canals.
On 11 October, a joint operation will be conducted at Helderkruin in Region C to fight the spread of alien plants growing in the area, specifically black wattle trees (Acacia mearnsii) and bugweed (Solanum mauritianum).
Some examples of invasive plants found near rivers, dams and streams include:
- Water hyacinth (Eichhornia crassipes) – Category 1b
- Yellow flag iris (Iris pseudacorus) – Category 1a
- Giant reed (Arundo donax) – Category 1b
- Indian shot (Canna indica) – Category 1b
Two more dates are set for 2016 invasive species and herbicide training:
18 and 19 October, 2016 – Pietermaritzburg, KwaZulu-Natal - Dante Hall, DA Language Institute (Società Dante Alighieri), 21 Alice Grange Rd, Scottsville, Pietermaritzburg
15 and 16 November, 2016 – Gauteng – venue details to be confirmed.

What does the training entail?
Module 1: Train to become an invasive species consultant
• NEMBA legislation and Invasive Species Regulations
• Landowners, estate agents & lawyers ‘duty of care’
• Control plan guidelines for organs of state & protected areas
• Permitting, compliance & directives
• Invasive species
Module 2: Introduction to herbicides and control methods
• Invasive species clearing using herbicides
• Herbicides and the law
• Selecting control methods for invasive species clearing
• Professional herbicide training
Join the network of invasive species consultants
All trained professionals will be listed in a SAGIC database of invasive species consultants (www.sagic.co.za & www.invasives.org.za) and will receive a certificate to indicate that they have attended the workshops.
People who attend the module on Invasive Species Control Plans will get an insight into the invasive species control plans that every organ of state (eg. municipalities) need to have drawn up by October 2016.
Did you know?
• Invasive species are defined as a liability under NEMBA. Any person who owns land in South Africa now has a ‘legal duty of care’ to control the invasive species on their land and anyone selling land, must inform the buyer of their land, of any invasive species on the property.
• That under the NEMBA AIS Regulations... all organs of state - which includes municipalities, metros, parastatals (Eskom, Transnet, SANRAL), protected areas (SANParks, all Nature Reserves), military bases, ministry’s, provinces and all state educational facilities - are required to submit control plans, which outline how they will deal with the invasive species on land under their control, to the Biosecurity Unit, Department of Environmental Affairs by 1 October 2016.
• Applications can now also be made to have a directive sent to any landowner who is not controlling listed invasive species on their property. Under these circumstances, large landowners will need the assistance of environment-trained professionals to identify species, develop and submit control plans to the government - to avoid prosecution.
SAGIC invasive species and herbicide training is an entirely self-funding project.
