A new invasive plant species has been identified on the Agulhas Plain. The Evergreen Kangaroo Paw (Anigozanthos flavidus) has been located on two properties in the area. Although the species has not yet been listed as an invasive plant under the National Environment Management: Biodiversity Act (NEMBA), it is considered a threat to the Western Cape.
The South African National Biodiversity Institute (SANBI) is now working with Flower Valley Conservation Trust to control and look to eradicate this species on the properties. These two partners will now work closely in piloting efficient treatment and control measures, which will include data collection on treatments, population size and the rate of spread. Flower Valley coordinates the Agulhas Biodiversity Initiative (ABI) Alien Clearing Programme.
The Kangaroo Paw stems from Southwest Australia, although it is commercially grown in other countries throughout the world, including the USA and Japan. It is used as an ornamental flower, with some of its artificial hybrids used for the cut-flower market.
Due to its adaptability to different soil types, and ability to cope with water stress, it is considered a threat. The species is also immune to most fungal attacks. It’s believed that the species can be eradicated from the Agulhas Plain, given that it is believed to not have spread beyond the two properties as yet.
