The Wanganui District Council tree strategy which aims to manage the city's urban treescape will be released within the next few weeks.
Councillor Helen Craig, who chairs the council's tree policy committee, said the strategy would replace the tree policy which had been drafted in 2008.
Mrs Craig said "love them or hate them", the city's street trees were here to stay.
The strategy comes after protracted debate last year about the removal of some 130-year-old trees as part of the Taupo Quay upgrade. Mrs Craig said that issue highlighted the need for council to have clearer guidelines in future.
There was a significant cost to managing the street trees, which underlined the importance of the strategy. At present the council's total annual cost attributed directly to trees, including landscaping, is $442,000.
