Gleditsia triacanthos (weed) (Lmk.) L. - (honey-locust)

The honey-locust tree is native to parts of North America and often grown as an ornamental in other regions. It has become invasive in several areas like parts of South America, Europe, southern Africa and Australia. For example, in Argentina it is one of the most invasive weeds of grasslands, disrupting the ecology (Fernandez et al., 2017).

The tree grows to a height of up to 25 m and the trunk is covered with strong thorns, up to 15 cm long. The pods are eaten and transported by cattle and other livestock. The seeds are durable and can survive for around 20 years. Passage of the seed through the digestive system of an animal promotes its germination.
