Lottery boost to the grey squirrel fertility control programme

During Red Squirrel Awareness Week, 02-08 October 2023, the UK Squirrel Accord (UKSA) thanks the Red Squirrel Recovery Network (RSRN) partners for including an important trial in their exciting new National Lottery Heritage Fund (NHLF) project. UKSA will work with RSRN, the Animal and Plant Health Agency and The University of York on a focused trial to better understand how grey squirrel fertility control can be effectively delivered at a landscape scale. As well as community engagement activities aimed at raising awareness of fertility control as a method for grey squirrel management.

RSRN is a partnership project involving the Northumberland Wildlife Trust, Cumbria Wildlife Trust, Lancashire and Merseyside Wildlife Trust, Knowsley Safari and Southern Uplands Partnership in Scotland. This ambitious project brings together conservation partners and community groups across Southern Scotland and Northern England.

Alongside other important red squirrel conservation and engagement activities, the RSRN project will include a cross-border trial that will provide volunteers with skills and equipment to effectively deploy species-specific feeding hoppers. In future, these feeders will contain a bait with an oral contraceptive for the non-lethal management of grey squirrels. Data will also be collected to help optimise bait delivery methods. Activities for the trial will be defined over the coming development phase year and will be guided by the needs of the research and practitioners. It will then be delivered collaboratively during the full five-year project.

Widespread established invasive species, such as the grey squirrel, are particularly difficult to manage. We need to find new and innovative ways to reduce their populations and negative environmental and economic impacts. Fertility control is increasingly advocated around the world as a non-lethal method for managing wildlife populations. Public support for this work continues to grow as the science evolves and as new contraceptives become available.

The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services recently published results of its four-year assessment on invasive non-native species and their management. They found that invasive species play a key role in 60% of all plant and animal extinctions around the world. They also estimated that these species cost the global economy over $423 Billion a year, a figure which has quadrupled every decade since 1970.

Management of established invasive species is most effective when a range of methods are available. Fertility control should offer a less labour-intensive and more publicly acceptable option than current lethal methods. It could be used alone or to complement other methods to reduce grey squirrel densities. This will help protect the UK’s remaining red squirrels and newly planted broadleaf trees.

RSRN brings more hope to the work of dedicated volunteers and conservation organisations across many borders of this vital red squirrel area. UKSA will support this important project through match funding and engagement. As we celebrate red squirrels during this important awareness raising week, we take another step closer to red squirrel recovery across the UK.

Kay Haw, Director of the UK Squirrel Accord, said:

“Collaborative landscape-scale action is needed to protect red squirrels and trees by effectively reducing grey squirrel numbers and their negative impacts. The Wildlife Trusts are important partners in the UK Squirrel Accord and we are delighted to contribute to a project that benefits the needs of two UK countries. We are grateful to the National Heritage Lottery Fund for supporting our work to develop a grey squirrel fertility control option.”

Dr Giovanna Massei, Europe Director of the Botstiber Institute for Wildlife Fertility Control based at the University of York, said:

“I am thrilled to continue to work with UKSA and with the other project partners and to build on the research that UKSA has supported for years. This project will expand the scope of fertility control applications for grey squirrels to larger areas and it will also raise awareness about the use of this method in the context of red squirrel conservation”

Sarah Beatham, APHA Wildlife Ecologist, said:

“It is great to be part of such a large-scale collaborative project that is so important for ensuring the long-term survival of the red squirrel in the UK. This project will allow us to lay key foundations that will, in the future, support the effective delivery of contraceptives as an additional method for managing grey squirrel populations, to give the red squirrel the best chance of success.”
