Stewart, G.H.; Ignatieva, M.E.; Meurk, C.D.; Earl, R.D. 2004. The re-emergence of indigenous forest in an urban environment, Christchurch, New Zealand. Urban Forestry & Urban Greening 2: 149-158.

In this article we examine the indigenous and exotic shrub and tree components of the Christchurch flora as planted street trees, in domestic gardens, and in parks. We also present data on tree and shrub regeneration in parks and domestic gardens in the city. Indications are that the more sensitive, less intrusive management of urban enviornments, combined with the greater density of indigenous seded sources, has already allowed regeneration of a wide range of indigenous species across a broad spectrum of habitats—from neglected gardens to pavement cracks to exotic plantations. If present trends continue through appropriate management and facilitation, native forest regeneration should proliferate into a sustainable mixed origin urban forest that resurrects and preserves the natural character of the region.
