Grey Squirrels

Jim Shannon Excerpts

[Virginia Crosbie (Ynys Môn) (Con)]

I beg to move,

That this House has considered control of the grey squirrel population.

Thank you, Mr Vickers, for the opportunity to hold this important debate on control of the squirrel population. I also thank my hon. Friend the Member for Copeland (Trudy Harrison)—a fellow atomic kitten. It was while we were visiting nuclear reactors in Finland recently that we discussed this important debate.

In the 1909 poem “An Appointment” by the Irish poet W. B. Yeats, he described the red squirrel as “proud” and “wayward”, bounding and springing around the trees with a

“fierce tooth and cleanly limb”.

He finished by saying:

“No government appointed him.”

Just two years after he wrote those words, American grey squirrels were introduced to Ireland and, as has been the case across much of the UK, this hardier and more aggressive species took over, pushing the red squirrel out and threatening its very existence. Although no Government appointed the red squirrel in Yeats’s poem, it is clearly up to our Government to reappoint red squirrels, a much-loved native species, to their natural homes. Grey squirrels are a menace to British biodiversity. They have proven perilous for our native red squirrel population.

[Jim Shannon (Strangford) (DUP)]

The Ards Red Squirrel Group is full of fantastic volunteers who work tirelessly to protect the future of the red squirrel in my constituency of Strangford, particularly at Mount Stewart. The organisation is led by the National Trust Mount Stewart ranger team, and they are in constant contact with local landowners to monitor red squirrels and eradicate any greys that venture in. Indeed, the issue is the very presence of grey squirrels; grey squirrels are the Hamas of the squirrel world. Does the hon. Member agree that there should be greater integration between the Department for Environment, Food and Rural Affairs and local red squirrel groups in the devolved institutions to ensure that they have the means necessary to preserve and expand the red squirrel species throughout Northern Ireland?

[Virginia Crosbie]

I thank the hon. Member for his intervention. He is a keen advocate not only for his constituents, but for the red squirrel population. I particularly thank him for drawing attention to those who work so hard on this issue. He mentions co-operation with DEFRA on red squirrels. It is absolutely key to all aspects of biodiversity that we see such co-operation.

In the UK, there are now an estimated 280,000 red squirrels. That is just 10% of the grey squirrel population. I am fortunate that many of those red squirrels reside on my island constituency of Ynys Môn in north Wales, which has been grey squirrel free since 2016. An estimated 60% of the Welsh red squirrel population thrive in woodlands such as the Dingle in Llangefni, Penrhos on Ynys Gybi, Newborough forest and the National Trust’s Plas Newydd. I was thrilled to be invited by Dr Rajkumari Jones to become an honorary member of the Red Squirrels Trust Wales, and to be shown around Pentraeth forest by red squirrel champions Rob Macaulay and Dr Craig Shuttleworth.

In 2018, a review of the population and conservation status of British mammals noted a significant decline in UK red squirrel populations over the preceding two decades everywhere except Scotland. The report identified that the decline was due to diseases such as squirrel pox and adenovirus; competition with grey squirrels for resources; deterioration in habitat quality; and a failure to implement effective measures to control grey squirrel populations. Grey squirrels cause millions of pounds-worth of damage to our woodlands by gnawing the bark off trees. That can lead to the loss of particularly vulnerable tree species, such as beech. That in turn creates a decline in the fungi and invertebrates reliant on those trees. In some cases, the damage caused by grey squirrels reduces the value of timber to the extent of disincentivising investment in the creation of new woodlands. The estimated annual cost of grey squirrel damage to trees is £37 million, and the estimated cost to the whole economy of grey squirrels is £1.8 billion.

This Government have taken steps to control the grey squirrel population and protect red squirrels. As we have seen, the Environment Act 2021 includes a legally binding target to halt species decline by 2030. The England trees action plan, published in May 2021, states that we will act now to build resilience in our woodlands by improving the management of grey squirrels, including by updating the grey squirrel action plan. We are now two years on from the Environment Act and 30 months on from the England trees action plan, but the updated grey squirrel action plan has yet to hit our bookshelves. The current plan provides advice to landowners on controlling grey squirrel populations on their land. Provision is also made for countryside stewardship grants to help landowners control the squirrel population.

I was pleased to see that the promised species survival fund was launched earlier this year, and look forward to red squirrel projects receiving support when the results are announced. The Government recognise that this issue is bigger than just giving grants to landowners. To achieve our 2030 target and our 2042 ambition to grow native species populations by 10%, we need focused, sustainable and joined-up action, and we need it soon.

Let us consider the various ways that the targets can be met. The first is through the traditional methods of grants to landowners, to support trapping and shooting of grey squirrels. Although that is effective, it is not always expedient. The Forestry Commission squirrel control plan reminds us that

“the time required to cull high-level populations must not be underestimated, nor should the total period over which a high culling effort will be required”

and

“even after populations are reduced, the time to sustain lower population levels can remain as high as it was previously, despite fewer animals being culled.”

Put simply, squirrel migration may simply displace the problem, and smaller populations are harder to hit. Trapping and shooting are also unpalatable to many people, and there are other more effective methods that need to be considered. I recommend the excellent report “Saving the Red Squirrel: Landscape Scale Recovery,” edited by Bangor University’s Craig Shuttleworth, along with Nikki Robinson of the Red Squirrels Trust Wales and Peter Lurz from Edinburgh University. Its production was supported by my local authority, Anglesey County Council.

That publication looks at alternatives in depth, and I would like to highlight some of the proposals reviewed. One is the reintroduction of pine martens as a method of biocontrol. Those native creatures have been largely extinct in England and Wales since the early 20th century. They prey on squirrels and, because grey squirrels are slower, larger, more populous and spend more time on the ground than their red cousins, they are easier prey for the pine marten. As non-native species, grey squirrels also lack the instinctive anti-predator response to pine marten scent that makes our red squirrels run for cover at one sniff.

There are an estimated 3,000 to 4,000 pine martens in Scotland. That may be in part why red squirrel populations are healthier north of the border. Pine martens have been reintroduced in various areas of Northern Ireland. In recent years, controlled studies have reintroduced them to parts of Wales and the Forest of Dean.
