Abstract

This paper is a first attempt to describe the flora of domestic gardens from an urban environment in South Africa. A total of 835 plant species of 501 genera in 145 families was recorded from 100 gardens in a 54.9 km2 area of the Tlokwe City Municipality [Potchefstroom], North-West Province. A substantial number of alien species (580) were recorded, but also many indigenous species (255) that included South African endemics (61) and protected species on the National Red Data List (18). A number of the alien species that were commonly cultivated are declared invasive plants in South Africa (88). Most of the cultivated indigenous taxa originated from the southeastern provinces of South Africa.

This study provides new knowledge on the often overlooked biodiversity of urban areas in a developing, mega-diverse country. Most studies of a similar nature were conducted in the developed countries of Europe and are of limited use in the development of management plans of urban ecosystems in southern Africa.
