A housing developer has lost an appeal against Brecon Beacons National Park to replace seven cherry trees in a conservation area.
Wyro Developments Limited, from Shropshire, felled the trees in Talgarth, near Brecon, in 2008 as part of plans to build homes in the area.
Wyro launched an appeal after the park issued the firm with a tree replacement notice, but it was dismissed.
The company said it had never objected to replanting the trees.
The appeal by Wyro Developments, based in Marton, near Shrewsbury, was dismissed by the Welsh Assembly Government's planning inspectorate.
Giving his reasons for refusing the appeal, the planning inspector said: "The trees that have been felled were not subject to a tree preservation order, but were within the Talgarth conservation area (TCA).
"The trees were on top of a low bund [artificial embankment] that separated the appeal site from the adjacent public car park.
"I found the numerous mature trees with the TCA make a significant contribution to its character and appearance.
"In light of the photographs of the area taken before the trees were felled I consider the trees in question made a positive contribution to the TCA.
"Their removal has resulted in the loss of the screening between the car park and the adjacent area of unused land to the detriment of the character and appearance of the TCA."
Ashley James, of Wyro Developments, said the the firm's appeal was "in the interests of good planning", and it was considered to be in the public interest to seek the replanting as part of a "composite development proposal" for the site.
He said: "We must stress that the principle of replanting the trees was never objected to.
"Indeed we would have thought that it would have been common sense as well as an enhancement for the area for the replanting to complement the location rather than reinforce the bund, a feature that has always been a temporary barrier, erected by the local authority.
"Despite this setback, our planning consultants are in the process of preparing a revised planning application for the comprehensive redevelopment of this gateway site," he said.
"This application will be submitted in spring 2011."
