Why is it a problem?
Altering soil chemistry, lowering veld carrying capacity and preventing access to watercourses when occurring in dense thickets. They can also replace indigenous vegetation to the detriment of the ecosystem as a whole. Also able to survive in a wide variety of environments, forming very dense patches that dominate native habitats. The prevalent sharply-toothed leaves of wintergreen barberry drastically limit its predators, allowing it to grow virtually unchecked.
