Ash dieback disease has been reported at seven sites in Scotland according to a survey by Forestry Commission Scotland.
Environment & Climate Change Minister, Paul Wheelhouse said:
Further surveys, including more detailed surveys in areas around infected sites, will be needed before we can be confident about the full extent of the disease in Scotland.
Experts say little can be done to stop the spread of 'Ash dieback' the disease threatening to devastate the UK's ash trees.
One of the UK's biggest tree growers will seek damages from the government after losing thousands of trees to ash dieback disease.
The disease threatening to wipe out the majority of Britain's ash trees may have spread - as experts say an import ban was too slow.
