A photograph of a compost heap at Agropolis, an urban farm on the corner of High Street and Tuam Street. Organic waste from inner-city hospitality businesses is composted and used to grow food. Agropolis was the venue for several events throughout FESTA 2013.

A city’s planted trees, the great majority of which are in private gardens, play a fundamental role in shaping a city’s wild ecology, ecosystem functioning, and ecosystem services. However, studying tree diversity across a city’s many thousands of separate private gardens is logistically challenging. After the disastrous 2010–2011 earthquakes in Christchurch, New Zealand, over 7,000 homes were abandoned and a botanical survey of these gardens was contracted by the Government’s Canterbury Earthquake Recovery Authority (CERA) prior to buildings being demolished. This unprecedented access to private gardens across the 443.9 hectares ‘Residential Red Zone’ area of eastern Christchurch is a unique opportunity to explore the composition of trees in private gardens across a large area of a New Zealand city. We analysed these survey data to describe the effects of housing age, socio-economics, human population density, and general soil quality, on tree abundance, species richness, and the proportion of indigenous and exotic species. We found that while most of the tree species were exotic, about half of the individual trees were local native species. There is an increasing realisation of the native tree species values among Christchurch citizens and gardens in more recent areas of housing had a higher proportion of smaller/younger native trees. However, the same sites had proportionately more exotic trees, by species and individuals, amongst their larger planted trees than older areas of housing. The majority of the species, and individuals, of the larger (≥10 cm DBH) trees planted in gardens still tend to be exotic species. In newer suburbs, gardens in wealthy areas had more native trees than gardens from poorer areas, while in older suburbs, poorer areas had more native big trees than wealthy areas. In combination, these describe, in detail unparalleled for at least in New Zealand, how the tree infrastructure of the city varies in space and time. This lays the groundwork for better understanding of how wildlife distribution and abundance, wild plant regeneration, and ecosystem services, are affected by the city’s trees.

Hand-written signs on the fence opposite the Gap Filler Pallet Pavillion advertise events at the pavillion. One advertises a plant sale on Saturday 22 December, the other high teas and cakes on Sunday 23 December.

Plant beds made out of corrugated iron, greening the empty building sites along Colombo Street. These were placed here by Greening the Rubble, a community project in Christchurch to create temporary public parks and gardens on the sites of demolished buildings.

A photograph of the location of the Green Room garden on Colombo Street. White picket fences have been placed around the edges of the site and a platform has been constructed in the back-right corner. Two garden plots have been sectioned off using bricks to the right and front of the site. The front plot has been planted with shrubs and grass. A path leading between the gardens up to the platform has been filled with gravel. Wire fences have been placed around the entire section as a cordon.Crack'd for Christchurch comments, "The Green Room was built by Jonathan Hall and planted by Gina Payne."

Damage to the garden of a house in Richmond. Liquefaction is visible among the plants and on the driveway. The photographer comments, "These photos show our old house in River Rd and recovery work around Richmond and St Albans. Back lawn under 10cm of water and silt".
