Invasive alien plants – a huge cost to companies.
Clearing land infested with invasive alien plants can cost up to R 10 000 per hectare
These days legislation regulating the prevalence of invasive alien plants on private land comes into play when buying and selling property, so landowners are paying a lot more attention to the matter than previously was necessary.”
“So, where does your responsibility as a land owner start in dealing with invasive species, asks Meiring?” According to the laws governing invasive alien plants on private land, landowners should be aware of which invasive alien plants are growing on their land, and eradicate those plants where they occur”.
Continues Meiring, “for landowners in urban areas invasive species are not such a big deal, but for landowners in rural and semi- urban areas this could be seriously problematic. A prime example is smallholdings on Wilderness Heights, Knysna and on the outskirts of Mossel Bay, where land is carpeted by black wattle, pines and blue gums (not to mention pampas grass, Madeira vein and Lantana”.
“Costs to clear land densely covered by invasive species (for instance black wattle) could be as high as R10 000 per hectare for an initial clearing operation by contractors. For many landowners the task to clear their land, and to keep their land clear of regrowth, is often simply too costly and time consuming to consider”.
Nevertheless, continues Meiring, ” the pressure on landowners to bring the state of their land up to a standard, (free of invasive alien plants), and the matter can no longer be ignored”. “Question is how does land owners deal with the costs associated with invasive alien plant management?”
“Often easier said than done, landowners whose properties are badly affected by invasive species should devise a simple strategy in tackling the problem, and deal with it in sections rather than biting off more than they can handle and keep under control”.
“Land cleared of invasive plants generally recovers by itself if re- growth of invasive species are kept under control, and although natural vegetation is the ideal, even grass cover is preferable to wattle jungles.”
“So, our advice to effected landowners is to take it one step at a time, make steady progress and curtail costs as you go along”.
