With 14,500 street trees in Orange, councillors have asked for more help for their management.
Mayor Reg Kidd said there had been a lot of instance of dieback - a condition in trees in which peripheral parts are killed, either by pathogens, parasites or due to conditions like acid rain and drought - in the past decade, yet Orange City Council has only have one team made up of a leader, two arborists, and a horticultural assistant.
And they are struggling to keep up with the required workload.

"It's a hell of a lot of work," Cr Kidd said.
"I just don't think with that team there - they'd be going flat chat for 10 years just to catch up with what we actually have."
Cr Kidd said the problem areas were those with a number of ash trees, including Cox Avenue, Frederica Street and Wiare Circuit, and felling a tree was a long process.
He asked for a report on how long it would take the team to catch up.
"We've got to look at our level of service but the longer we put it back, the further we're going to get back," he said.
"They're good operators, but terribly under-resourced."
General manager Garry Styles said extra resources would be considered in the budget.
Councillor Stephen Nugent said it was positive more street trees had been planted than removed - 358 versus 76 - but was still interested in the idea of tree bonds in subdivisions and asked for a follow-up report on how they might work.
