Red squirrels now under threat in Scotland’s south
Only 59 of the rodents were detected in 2017 and 2018, with a shift in favour of greys.
However, the Saving Scotland’s Red Squirrels study is optimistic overall for the future of red squirrels in Scotland’s north-east and central lowlands.

Researchers suggest it shows greys are continuing to move into what was previously “red only” territory.
Project manager Dr Mel Tonkin said: “Grey squirrels have continued to spread in some parts of southern Scotland, particularly in the eastern Borders and in the Nithsdale area of Dumfriesshire.
“It is vital that the work we do in priority areas is stepped up to make sure that the red squirrel populations in these areas remain healthy.”
The most positive survey results were found in north-east Scotland, where red squirrels continue to expand their range, particularly around Aberdeen.
