Saving Scotlands's Red Squirrels is a partnership project that is working to ensure red squirrels continue to be a part of Scotland's special native wildlife.
The project controls grey squirrels by live-trapping them then despatching the animals in the most humane way possible. They welcome feedback on both red and grey squirrel sitings which can be recorded on their website site.
Their website is very comprehensive. There is a link to it at the bottom of this page.
