A picture built over time: red squirrels in Gatehouse of Fleet

Dr Peter Garson from Gatehouse Squirrel Group shares insights from nearly a decade of careful observation and community-led conservation in southwest Scotland. This case study highlights how long-term monitoring, local engagement and an understanding of place are helping red squirrels remain a familiar sight in the woodlands around Gatehouse of Fleet.

Nestled by the coast midway between Dumfries and Stranraer, the small town of Gatehouse of Fleet sits within a rich mosaic of old mixed deciduous woodland and conifer plantations. With the Galloway Forest Park just to the north, this varied and well-connected landscape supports a wide range of wildlife and provides an ideal setting for the thoughtful, long-term work of Gatehouse Squirrel Group.

The group took its name in 2015, at a time when grey squirrels began appearing locally and questions were asked about what this might mean for the future of the red squirrel. From the beginning, the group adopted a measured and evidence-led approach of observing carefully, recording consistently, and avoiding assumptions.

We were going to have to concern ourselves with grey squirrels if our local reds were going to survive in long-term. Maybe we had arrived ‘just in time’ to stop an apparently inevitable takeover?

Early efforts focused on understanding what was really happening on the ground. Volunteers logged red and grey squirrel sightings with Saving Scotland’s Red Squirrels (SSRS), whilst also carrying out surveys using feeder boxes with sticky pads to collect hair samples and deploying trail cameras. These surveys quickly revealed red squirrel presence across all large woodland blocks accessible to the group, with no greys detected at that stage, providing both reassurance and a clear baseline for future monitoring.

Over the following decade, Gatehouse Squirrel Group has built a strong and committed local network of contributors. Today, more than 100 local people submit records, creating a valuable long-term picture of squirrel activity across the area. Peter uses these records, alongside submissions to SSRS, to track trends over time, allowing changes to be noticed, questioned and better understood.

One of the group’s most effective initiatives has been the development of a simple but robust method for monitoring red squirrels in local gardens. Since 2017, householders have recorded the maximum number of red squirrels seen at any one time each month, as well as the number they can recognise individually. This approach has encouraged people to look more closely at the wildlife sharing their spaces and has provided a consistent way of tracking red squirrel presence. As Peter reflects, it also highlights “how lucky we are to live beside them so intimately”.

Maximum numbers of red squirrels seen at once per month in survey gardens during spring and autumn 2017-25, standardised to 20 gardens to correct for variations in the number of counts returned (15-27 per month). Survey gardens are distributed from the coast south and west of Gatehouse, around the fringes of the town, up the Fleet valley to the north and out to the east.

What is particularly striking is the picture that has emerged from these long-term efforts. Despite wider national trends, the data suggests that red squirrel populations in the Gatehouse area have remained broadly stable over time. Peter describes this as comforting to observe, while also acknowledging the limitations of citizen science and the importance of interpreting results with care. While figures from garden surveys cannot be directly compared with woodland populations, there is growing confidence that red numbers have remained largely unchanged over the past nine years, even as grey squirrel records increased, at least until recently. New evidence suggests greys may be in retreat.

Whilst the group continues to do what it can to slow the spread of grey squirrels, Gatehouse Squirrel Group has also paid close attention to wider ecological changes in the area. In recent years, there has been a noticeable increase in local pine marten records, with the species appearing on trail cameras, visiting feeders and even being spotted by walkers during the spring and summer months. The return of this threatened native carnivore marks a significant and encouraging shift in local fortunes. Research on pine martens in Ireland and elsewhere in Scotland has shown that they can play an important role in suppressing grey squirrels whilst allowing red squirrels to recover.

It would indeed be rewarding if we can eventually conclude that by assisting the recovery of the pine marten, persecuted almost to extinction over most of the past two centuries, we have also helped the red squirrel to survive the often overwhelming threat posed by the grey and the poxvirus it carries, in this small corner of Galloway.

Gatehouse Squirrel Group has embraced this broader ecological perspective through collaborative work with the Dumfries & Galloway Pine Marten Group, helping to support pine marten populations recovery locally. Peter reflects on this with thoughtfulness, wondering whether it is the pine martens rather than the volunteers who have arrived “just in time”. Either way, it is clear that the group’s careful observation, partnership working and long-term commitment are making a positive difference.

Made possible with the Heritage Fund

Now recently registered with the Red Squirrel Recovery Network, Gatehouse Squirrel Group brings with it years of local knowledge, community engagement and a willingness to learn from the data. As part of a network spanning northern England and southern Scotland (including work across Galloway & Southern Ayrshire Biosphere, Restoring Upland Nature, and Bright Green Nature), Gatehouse Squirrel Group's efforts reflect the strength of patient, locally rooted conservation built on collaboration, curiosity and a deep understanding of place. We are incredibly grateful to have them on board.

This project is made possible by the National Lottery Heritage Fund, with thanks to National Lottery players.
