Sandy the Squirrel – the Trust's epic adventurer – set out from Aberdeen early on 30 November to complete a very special mission.
In days gone by, red squirrels would have been able to get from one side of Scotland to the other without touching the ground, simply by jumping from tree to tree. Unfortunately, thanks to habitat loss, urban development and the spread of grey squirrels northward, the only way Sandy can make this journey now is by public transport!
You can relive Sandy's fantastic adventure in the video below, travelling all the way from Aberdeen to Glasgow on ScotRail trains. You can also see photographs and post comments on the Trust's social media.
