Chandelier plant

The chandelier plant is also known as the mother of millions. It is easily propagated through broken cuttings and seeds and therefore should never be dumped, but sealed inside a black plastic bag until the plant fragments are completely dead. Once established, this plant is difficult to remove as the roots embed themselves firmly under rocks and inside rock crevices. The plant breaks easily leaving the roots behind.

Bongo

The Bongo is an attractive antelope related to the kudu and bushbuck genus. There are two recognised subspecies – the Western or lowland bongo (Tragelaphus euryceros euryceros) which occurs widely across lowland forest of West and Central Africa, and the Eastern or mountain bongo (Tragelaphus euryceros isaaci) confined to mountains of central Kenya. This antelope is listed as a Category 1a species under the NEMBA Alien and Invasive Species Regulations.

Common boa

The common boa is a popular captive snake in the reptile industry. However, under the NEMBA Alien and Invasive Species regulations, a permit is required to keep them in KwaZulu-Natal, the Eastern Cape, Limpopo and Mpumalanga. There is concern that if these snakes escape captivity, they could survive in the warm climate offered by these provinces.

Bluegill sunfish

The North America bluegill sunfish was introduced to South Africa in 1938 as a fodder food for bass. Like bass, they have spread far and wide and in waterways where they have few predators, their population can grow rapidly and outcompete indigenous fish such as tilapia. It is found throughout most rivers and dams in southern and eastern South Africa.

Bloodberry Rivina

Rivina or bloodberry thrives in shaded forests and along rivers and streams where it can form dense thickets. All parts of the plant are poisonous therefore wild animals avoid eating it. Having few natural enemies, it grows rampantly at the expense of indigenous trees and shrubs.

Balloon vine

Balloon vine is a prolific climber which smothers indigenous shrubs and trees. It clambers over trees and blocks out sunlight to indigenous species disrupting photosynthesis. This in turn weakens the underlying tree which may eventually die. The tangled network of vines makes this climber difficult to control.

Asian kelp

Asian kelp (Undaria pinnatifida) is a popular food species in Asia. In Japan it is known as wakame and used in many different dishes. However, it is a highly invasive marine species which has established itself in parts of Europe, North America, Australia and New Zealand.

It may cause displacement of native species. It can change the structure of ecosystems, especially in areas where indigenous seaweeds are absent. It is also said to have potential to become a problem for marine farms by increasing labour and harvesting costs due to fouling problems on fin fish cages, oyster racks, scallop bags and mussel ropes. Heavy fouling may also restrict water flow through cages.
