Measures of plant and insect diversity show the role of civic-led greening in linking conservation to the ‘good and just city’.
•
Civic-led interventions can contribute towards urban conservation agendas with the acknowledged exclusion of fire.
•
How to integrate civic-led interventions into urban biodiversity planning remains an open question.

Parks and private and public gardens do not exist in isolation, but form part of the urban fabric, contribut-
ing to ecological functioning. There is growing interest in how civil society shapes urban ecologies and
vegetation patterns. This paper explores the ecological outcomes of a series of indigenous plant greening
interventions in Cape Town. The six different sites were sampled: two civic-led intervention sites, one
expert-led rehabilitation site, two conservation sites and one abandoned site. These sites are compared
in terms of their plant and insect diversity and then discussed in relation to their contingent management
arrangements and in relation to conservation and abandoned land. Plant and insect diversity measured
at the civic-led greening intervention sites suggest these sites are similar to adjacent conservation sites,
while floristic composition differs. The inclusion of a vacant lot with poor species and growth form diver-
sity shows the significant role of intervention in the ecological reformation of urban green space. By
emphasizing the ecological outcomes, this study highlights the importance of civil society in linking con-
servation goals to more broad-based notions of quality of life and the ‘good and just city’. Our results
indicate that civic-led efforts warrant attention in keeping with those of experts, both in relation to
meeting indigenous conservation targets, as well as supporting functional groups and wider ecological
processes, with the acknowledged exception of fire. How to integrate such civic-led interventions into
urban biodiversity management planning is still an open question.

1. Introduction
1.1. Forging urban ecologies
Urban ecology is neither natural nor social, but rather a “recom-
binant ecology” (Barker, 2000). It has arisen from historical climatic
and vegetation conditions and shaped by multifaceted urbanization

processes of housing, transport, energy and telecommunication
infrastructure, but also the allocation of ‘green spaces’ (Niemelä
et al., 2011). Among the many heterogeneous urban land uses that
support ecological functions, the broad category of ‘green spaces’
are crucial in several ways. For example, urban forests, park areas,
sports fields, and water bodies and wetlands, have the capacity
to support biodiversity often restricted to these areas, mitigate
climate extremes, sequester carbon, provide educational oppor-
tunities, and facilitate the infiltration of storm water (Cadenasso
& Pickett, 2008; O’Farrell, Anderson, Le Maitre, & Holmes, 2012).
Studies have shown how such green spaces support critical func-
tions and services, in particular when services cannot be acquired
