Conference 2003
Greening the City:
Bringing Biodiversity Back
into the Urban Environment
Abstract:
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'.
