MSPs are being asked to declare the Scots Pine Scotland's national tree.
The evergreen can be found on dozens of windswept hillsides throughout the South of Scotland.
Nature lover Alex Hamilton is taking his plea to the public petitions committee at Holyrood this morning.
He says the gesture would make a symbolic commitment to woodlands and natural heritage.
He has the backing of the Woodland Trust, the Scottish Wildlife Trust and RSPB Scotland.
