? Projected cost/time frames for eradication of AIS in Western Cape: R3,9 billion – 18 years

? Projected cost/time frames for eradication of AIS in Eastern Cape: R8 billion – 72 years

? Stream flow reduction due to AIS in Western Cape: 529m3/annum

? Stream flow reduction due to AIS in Eastern Cape: 244m3 /annum

? National List of Invasive species (Total of 559): It includes plants (383), mammals, reptiles, amphibians,fresh-water fish, terrestrial invertebrates, fresh-water invertebrates, marine invertebrates and microbial species.

? A Booklet, “South Africa’s National Listed Invasive Species” with the full list in a 34-page A5 format, but not fully illustrated, is available from DEA.

? Aliens-a-coming… The Garden Route has been identified as suitable habitat for two approaching invasive species: Campanoclinum macrocephalum (Pompom weed, Gauteng baddie) and Parthenium hysterophorus (Famine weed, KZN and eastern parts of SA). Both create a sterile monoculture habitat and the latter, especially common on disturbed areas such as around homesteads, causes severe irritation, blisters etc. on contact to both humans and livestock.

  1. Ek is so bly vir die forum wat gestig is bly in Brenton on Sea Knysna en as die mense tog net die wilde piesangs en die Nieu-Zeelands Kersboom (lyk soos ‘n Bottle Brush) wil uithaal sal dit al baie help, waar kan mens kla dat die bure die goed uit hul tuine sal haal of verplig word om dit te doen daar is sulke mooi inheemse plante wat wild groei en hie hoort die ander uitheemse plante gebruik te veel water en lig sement, kraak die sholuns en gaan onder die huise se fondasie in.

    • The New Zealand Christmas tree is listed as a Category 1a invasive ONLY in the Overstrand area, and not listed as an invader elsewhere in the country, so I’m afraid it is allowed in gardens. Regarding the Strelitzia nicolai it is an indigenous species, and I agree it is a pest in Knysna as the starlings and even doves happily spread the seeds into forested areas.

  2. Daar groei lanings luisbome op die plaas langs ons eiendom in die Tsitsikamma. Ons sien gereeld swerms bosduiwe daar van die vrugte (dus ook die sade) vreet. Die duiwe gaan saans terug na hulle neste toe in die inheemse bos wat net aan die ander kant aan ons eiendom grens en ons het al opgemerk hoe van hierdie plante daar opkom. Die duiwe versprei ook die saad op ons grond en ons moet gereeld hierdie plante uittrek waar dit opkom. Waar kan mens die probleem aanmeld sodat die eienaar van die plaas daarop atent gemaak kan word dat hy die plante op sy grond moet verwyder?

    • Eerstens moet jy die eienaar adviseer dat die Luisbome (Solanum mauritianum) ‘n Cat. 1b plant is, en wetlik moet die plante verwyder word. Probeer om rasioneel en billik te wees, ‘n mens kan veel meer bereik deur vriendelikheid. As hy/sy reaksie agresief of onbillik is, kan jy in aanraking kom met Biosecurity Unit, Department of Environmental Affairs, Cape Town vir advies.
