As people migrated, seeds, plants, and ideas went with them. Some species naturalised with native species, whilst others were labelled alien invasive. This is a study of the interdependence between people’s decisions regarding the use of flora in an urban context. A Nelder plot (fig. 1), grown to walk through as an embodiment of the invasion or naturalisation history of flora. As the artwork matures, audiences learn why the various areas in the artwork feel different. We are conditioned to have a higher regard for megafauna and flora. This interspecies study can track how specific grasses influence tree growth: in a way how, minorities can influence majority rule. Participants’ reaction to different parts will also be influenced by their own histories. Cities are often uncomfortable for humans, a cold grey concrete jungle. Cities in the geological south, from a Gondwanaland lens (fig. 2), had more ancient savannas and warm tropical forests which differ vastly from the temperate ‘northern’ forests. How can future cities in the ‘south’ embrace our informal economies more sustainably? How can we adapt cities to be friendlier to the natural world?  I have an existing network of savannah ecologists, curators, and others to expand upon. We are confronted with a range of environmental and social ‘complex wicked challenges’ in the next decade (Funtowicz and Ravetz, 1995). This work (fig. 3) can mature within a decade to educate ourselves empathically about futures we want to grow.
