Greening the City:
Bringing Biodiversity Back
into the Urban Environment


The Ageing Tree Population of Christchurch

Dieter Steinegg (Tree Officer, Parks & Waterways Unit, Christchurch City Council)

The Christchurch City Council is preparing various strategies to deal with a raising number of declining trees in urban parks, streets and reserves. It is predicted that hundreds and even thousands of over-mature and declining trees in Christchurch need to be replaced over the next 10 to 30 years.

This provides a great opportunity to work towards an "ideal" urban environment, increased biodiversity, and other long-term planning objectives.

Systematic assessments are in progress to evaluate trees for their conservation status and degree of decline. Timely intervention will reduce the risk of loss of rare and unusual indigenous and exotic plants that are part of the natural and cultural heritage. For the urban tree environment to function to its highest potential, sustainable tree management strategies are promoted, to ensure overall vitality, and to maximise the aesthetic significance of the collection for future generations.

The management and the restoration of these valuable tree assets are of utmost importance to Christchurch's Garden City image. Combined team effort has been promoted to deal with oncoming issues in a proactive manner.

This presentation provides an overview of considerations, the work that is needed, and practical ways to sustain a wide range of suitable trees in the urban environment that make Christchurch a 'Garden City of the World'.
