RSPB Scotland will not object to plans to move T in the Park , but is disappointed at the "minimalist" measures to reduce the impact on birds and wildlife at its new home.

The charity is particularly concerned at what happens to an osprey nest at the proposed new site in the 1,000 acre Strathallan Castle estate in Perthshire.

The festival organisers have to shift the event because of concerns about an oil pipeline running under the Balado site near Kinross which hosted it for 17 years.

They advised by experts to move the osprey nest to another location within the estate in the next couple of months. The young would be likely to have either fledged or be about to fledge by the time the event takes place in July, they were told.

Perth and Kinross Council is due to formally consider the planning application for the festival soon, but a spokeswoman for RSPB Scotland said after detailed consideration of the proposals, the charity would not be objecting to the application to host T in the Park in the estate.

But they continued: "However, we remain disappointed with DF Concerts Limited's minimalist and rather last minute approach to mitigating their impact on birds and wildlife.

"RSPB Scotland has been working with SNH and Perth and Kinross Council to advise on how they can reduce the impact of this major event on wildlife, particularly on the resident breeding ospreys. DF Concerts, the T in the Park promoters, plan to remove the existing nest and construct a new nest a few hundred metres away before the ospreys return for this breeding season. This has been done successfully before and it is probable that the ospreys will simply move to the new nest site but this isn't a perfect solution and doesn't completely remove the risk of disturbance."

She said that ospreys were one of Scotland's most iconic species, and only 33 pairs bred in Perthshire last year. The site was also used by breeding kingfishers, red kites and barn owls, and our advice contains information on how to reduce impacts on all of these species.

She said "We are sure that the thousands of T-in-the-Park-goers would not want the festival to harm Scotland's wildlife and the concert should be a model of best practice in this regard. We therefore look forward to hearing what additional measures DF Concerts will provide to offset any disruption that the concert itself, and the months of setting up, may cause."

But in a statement DF Concerts & Events said: "We have been liaising with the RSPB , as well as independent experts and many other agencies, so we're pleased that this has been recognised and the RSPB has made no objection to the event taking place at Strathallan or to our plans for ensuring that there is minimal disruption to wildlife. We have also offered to start a working group with RSPB and SNH that would begin pre-festival and would allow us to take their ongoing advice."
