History in South Africa
Harrisia balansae has been recorded only in two provinces of South Africa, North West and Limpopo. In North West it has been recorded in Groot Marico where it is suspected to have escaped from an abandoned farm house. In Limpopo it has been confirmed in Modemolle at Mkleuw and 26 Succenvale Farm and Carlifonia Farm in Letsitele just outside Tzaneen.
Harrisia balansae inhabits forests and savannah biomes mostly dominated by species of the genus Acacia and in disturbed areas.
How to eradicate
