Invasive Animals

European flat oyster

Ostrea edulis

Ostrea edulis is a species of oyster. It is a sessile, filter-feeding bivalve mollusc, associated with highly productive estuarine and shallows coastal water habitats.  Each valve differs in shape and size; the left one (the one used by the oyster to attach itself to a surface) is concave, while the right one is flat and fits snugly inside the left. 

European goldfinch

Carduelis carduelis

The goldfinch is native to Europe, North Africa, and western and central Asia. It is found in open, partially wooded lowlands and is a resident in the milder west of its range, but migrates from colder regions. It is a popular cage-bird species and has been introduced to many areas of the world. 

European greenfinch

Carduelis chloris

The European greenfinch is a small passerine bird. It uses its powerful beak to break open seeds, which it feeds on throughout the year. In winter, it may form groups with other finches and buntings, and as natural seed stocks dwindle at this time of year, it increasingly relies on artificial food sources, such as bird tables. It nests in small colonies in trees and bushes, and only defends a very small area around its nest.

European paper wasp

Polistes dominula

A medium-sized wasp with a body length of 12-16mm. It is boldly patterned with black and yellow and almost identical to the German wasp – also invasive in the Western Cape. It has yellow and black bars on the abdomen and constructs communal paper nests in trees, shrubs and under roof eaves.

European pond turtle

Emys orbicularis

The European pond turtle is a long-lived freshwater species of turtle. It selects terrestrial locations with open, high and sandy soil habitats for nesting. It searches for habitats in shallow, fertile areas with adequate food supplies and few predators.
