Concerned residents contacted the Otago Daily Times saying the wilding pines that had been cut down near Shaky Bridge and the Alexandra clock ruined the landscape.
But Central Otago wilding conifer control group project manager Phil Murray said they would not be removed.
"It’s impractical and it wouldn’t justify the cost. The trees will just break down over time."
He said the trees would start to break down within about a year and in 10 years would be completely rotted.
He said many people had spoken to him about how much better the landscape looked.
"Many [people] comment on the landscape saying it hasn’t looked like this in 30 years."
Work to cut down the trees had been carried out on Matangi Station, the Little Valley Station and the Lower Manorburn reserve since November.
When the Otago Daily Times told Mr Murray the trees were covering part of a walking track near the clock, he said contractors had removed the trees from the walking track and put them to the side but he would ask the contractors to take another look.
The area around the clock is part of Matangi Station, owned by John Sanders.
Mr Sanders said some of the trees that had been cut down behind the clock would be removed by businesses to be sold as firewood.
He said the trees in front of the clock, near Shaky Bridge, would not be removed.
The Otago Daily Times reported in November the project was part of a nationwide programme to remove wilding conifers.
Conifers growing in the wrong places can damage landscapes and compete with native plants for sunlight and water.
