- Description: Colonialism is a significant legacy across most aspects of urban form, the nature and distribution of public green spaces, and tree species composition in many cities of the Global South. However, the legacy effects of colonialism on urban green infrastructure and the uses thereof have only recently come under scrutiny. Here we collate information from South Africa on urban greening and interpret it through a colonial and apartheid legacy lens in relation to the distribution and types of urban nature found and their resonance with contemporary needs as an African country.

- Description: Urban trees are vital components of urban ecosystems, and thus important for environmental quality, urban sustainability, and quality of life in cities. Regrettably, urban trees are sometimes unequally distributed both between and within towns, a pattern largely associated with differences in the social environment of cities and historical patterns of development, and the dearth in strategic management plans and systematic monitoring of the existing urban forest. Most management plans focus on ecological and arboricultural aspects at the expense of the social, and studies examining perceptions in relation urban forests are largely from developed countries. Accordingly, we conducted a study to examine the perceptions and preferences regarding urban trees of 1200 residents from 10 urban areas across multiple socio-economic contexts in South Africa.

- Description: Street trees are a common feature of urban nature, providing ecological, economic and social benefits. These public functions are highly dependent on specific design principles, including the composition and diversity of tree species within the urban forest. Consequently, it is important to understand the patterns and correlates of street tree distribution and diversity to assess benefit flows. This requires sampling across and within towns. This paper reports on an assessment of the distribution, composition and diversity of street trees between and within multiple South African towns, and ascertains the correlations between tree density and composition with social contexts. Randomly selected streets were sampled in the affluent, township and low cost housing suburbs of ten Eastern Cape towns. Sixty-nine out of 300 sampled transects had street trees, with 888 trees enumerated, spanning 97 species. Alien tree species accounted for 71% of all the enumerated trees while indigenous trees species accounted for 12%. Tree density and composition were significantly lower in smaller towns and those marginalised during the previous racially-based political regime. Within towns, the poor areas had fewer street trees, with many streets having none. Collaboration and constant communication between the various government departments involved in suburb development is crucial to ensure a more rigorous incorporation of green infrastructure into the building and development plans of new housing developments.

- Description: Urban green spaces and trees are increasingly recognised as crucial elements in the quest for urban sustainability internationally, and for the promotion of urban liveability and quality of life in cities. So much so that many countries now have guidelines or regulations regarding either the amount of urban greenery that must be provided per capita, or the maximum distance that any dwelling can be from green spaces of stipulated sizes. For example, the European Union recently more than doubled its recommendation of 9 m2 of public green per person to 20 m2 per person.

- Description: The planting and maintenance of trees in public areas of South African towns is the responsibility of local municipalities. Therefore, it is necessary to appreciate the visions and attitudes of municipal officials and decision-makers in charge of such activities for an understanding of the distribution and abundance of trees along streets and in urban green spaces. We hypothesised that the town size and relative wealth and current extent of trees in public places would influence the visions of such officials. We therefore conducted 24 semi-structured interviews with the officials responsible for urban tree planting in 24 towns in the Eastern Cape province, whilst also assessing the abundance of street trees via GIS counts. The density of street trees was variable, ranging from 0.5 to 9.5 trees/ha. There were significantly positive relationships between town size, relative wealth measures and street tree density. Several of the managers did not include environmental issues or trees in vision of the future for their town, although most did. There was no relationship between the managers’ visions for the future and attitudes and current street tree density. Most of the managers experienced several constraints in trying to implement their vision, notably a lack of funds for urban forestry, limited space for tree planting in low-cost housing developments, vandalism, and lack of skilled personnel.
