Scotland is home to around 75% of the UK's 160,000 red squirrels.
There is also a community of the creatures on Brownsea Island in Poole Harbour in Dorset, where a scheme has been set up to help protect them.
Research
Conservation groups have joined together to monitor and research the creatures to help prevent them from dying out.
Both schemes are part of National Red Squirrel Week, which started on Monday.
