English Red Squirrel Protection Group Reports Surge in Grey Squirrel Numbers

A prominent red squirrel conservation organization in England has reported experiencing an “invasion” by grey squirrels. The grey squirrel, which is larger, is categorized as an invasive non-native species and has played a role in the reduction of the indigenous red squirrel population. The Penrith and District Red Squirrel Group (P&DRSG), an organization that operates across 400 sq miles (1,036 sq km) within Cumbria, was established four decades ago following the initial sighting of a grey squirrel in the area. Robert Benson, the group’s founder, stated: “The last 18 months we have seen a huge increase in their numbers. Unless something changes soon, the reds will disappear from England.” The culling of grey squirrels, which originated in North America, is not prohibited by law, while releasing them from traps constitutes a criminal offense. The grey squirrel is a carrier of a poxvirus, which does not affect it but leads to a slow and agonizing death for red squirrels. Mr. Benson commented: “We think they are probably breeding in Cumbria all year round because of the milder weather,” adding, “We are certainly seeing pregnant and lactating grey squirrels in the winter months.” Mike Denbury, who serves as project manager for Red Squirrels Northern England, an initiative managed by Northumberland Wildlife Trust, indicated that the situations encountered by P&DRSG are “one I’m hearing everywhere.” He further explained: “We’ve had a couple of years when trees produce a lot of seed with a lot of food around for grey squirrels who like broad leaf species like hazelnut and beech.” Denbury also noted: “We’re definitely seeing grey squirrels breeding all year round.” A total of 47 groups operate across Northumberland and Cumbria, all dedicated to the conservation of red squirrels. Mr. Denbury asserted: “Frankly without their work, the red squirrel would have no future in England,” adding, “What we need is a more permanent solution, like gene editing, or contraception, or a vaccine against the pox which only affects the red.” He warned: “If it doesn’t happen soon, we’re going to lose the red squirrel from not just England but Scotland too in time.”
