The African tulip tree is an evergreen species indigenous to western Africa. It has been introduced throughout the tropics and is threatening biodiversity in many parts of the Pacific islands. It favours moist habitats and will grow best in sheltered tropical areas. The tree invades both abandoned agricultural land and closed forest. This species loves rich soil, but puts up with just about any type of soil.
Rubus ellipticus is a stout evergreen shrub with prickly stem that grows approximately 4.5 metres tall. Its stems are covered with prickles and reddish hairs. It has been introduced to several places, including Hawaii, Southern USA and the UK, and is grown in cultivation for its edible fruits. This plant has become a major pest in Hawai'i, threatening its own native species of raspberry (Rubus hawaiiensis), and the ability of this plant to thrive in diverse habitat types makes it a particularly threatening invasive plant.

Banana poka is a vigorous, scrambling, smothering plant that climbs up to 10 m high by means of its tendrils. It can smother trees, reducing native biodiversity and its fruit can encourage pest animals such as rats. Declared weed, prohibited and must be controlled in South Africa.
