What can we learn from a dead red squirrel?
Here at SSRS we use a lot of data to inform our work, determine priority areas and track the success of the project. From public sightings to camera trap images and hair sample ID, we gather this data from lots of different places, and in collaboration with many different people! One area we’re really interested in is red squirrel health across the country, particularly monitoring the prevalence of the deadly squirrelpox virus, which is carried by some grey squirrels. We caught up with Liam, from the Royal (Dick) School of Veterinary Studies, who carries out post mortems on red squirrels collected by SSRS and the public, to find out more about all the information we can learn from these.
The below post contains images of dead red squirrels.
Hi, I’m Liam Wilson, one of the vet pathologists at the University of Edinburgh, and I help run the mortality monitoring scheme for Scotland’s red squirrels. As you probably know, our native reds in the UK are under pressure from disease and from competition for food with the invasive non-native grey squirrel.
At the Royal (Dick) School of Veterinary Studies and the Roslin Institute, we’ve been running a mortality monitoring programme since 2005. This aims to understand the main causes of death in Scottish red squirrels, and to investigate any factors that might make them more vulnerable to certain threats, such as disease or in-breeding.
