Alien on my stoep
JOBURG – Are there hidden enemies hiding in your garden in plain sight?
There are surprisingly numerous types of alien plants and weeds invading our gardens.
According to Alien and Invasive Species regulations in terms of section 97(1) of the National Environmental Management: Biodiversity Act, 2004 (Act No. 10 of 2004) there are three categories of invasive and alien species.
Category one lists the species that must be destroyed or removed immediately.
Category two states that the species can be grown under controlled conditions.
Category three species and trees may not be planted at all.
According to City of Joburg, Ronnie Kasrils, Minister of Water Affairs and Forestry, said in 2000, “Invading alien plants pose huge threats to our environment. The most detrimental effects are those that threaten our water reserves, livestock and carrying capacity of the land.”
Any person according to the act above, “Who contravenes or fails to comply with a provision of these regulations is guilty of an offence and is liable, on conviction to pay…”
• A fine not exceeding R5 million, and in the case of a second or subsequent conviction, to a fine not exceeding R10 million;
• Imprisonment for a period not exceeding 10 years;
• To both such fine and imprisonment.
Johannesburg City Parks and Zoo outlined five most common invasive species that are encountered on a regular basis in Johannesburg.
Category one:
Bugweed (Luisboom);
Lantana
Category two:
Black wattle (Swart wattel);
Grey poplars;
Blue gum
Permits can however, be given in specific cases in each category.
