Tree Health in England

Baroness McIntosh of Pickering Excerpts

Thursday 9th June 2022 Grand Committee

[Baroness McIntosh of Pickering (Con)]

My Lords, I add my congratulations to the noble and right reverend Lord on securing this debate. Will my noble friend the Minister join me in paying tribute to and recognising the work of Fera at Sand Hutton, York, on tree health? I will refer to it in a moment.

In March 2014, in response to the immediate threat of ash tree dieback, the Environment, Food and Rural Affairs Select Committee, which I had the honour to chair, published a report, Tree Health and Plant Biosecurity. Its recommendations and conclusions have stood the test of time. I refer in particular to recommendation 18,

“that ring-fenced funding is provided for long-term research and development work that focuses on preparation for future plant health threats”;

recommendation 20, that Defra set up

“immediate initiatives … to address the lack of relevant expertise in the field of plant health”;

and recommendation 22, to develop resistant strains of ash trees without diverting funds from other, more immediate control measures. These recommendations have stood the test of time and I hope that Defra will continue to honour them.

It is a matter of note, as set out by my noble friend Lady Fookes, that there is a very wide range of potential tree and pest combinations that may be of concern heading towards this country. I welcome that Defra, FERA and others, such as Forest Research, contribute to Defra’s risk register, which helps to prioritise action against pests and diseases posing potential threats to UK species.

I take this opportunity to raise a number of questions with my noble friend the Minister. The practice of exporting ash tree seeds from the UK to, for example, Denmark and Poland—areas where trees subsequently reached high levels of infection in the early 2010s—and then reimporting them as saplings contributed at the time to infection of ash tree disease in this country. Will my noble friend consider whether it would be worth banning this practice outright rather than allowing it to continue, potentially contributing to the spread of the disease? Do we need to tighten up tree inspections at borders to ensure the health of trees and that they are safe to import? I refer to the fact that there is no longer a requirement to pre-notify consignments of high-risk trees, yet all plants for planting are effectively pre-notified via the phytosanitary certificate system. I am told that saplings coming into the UK will have been classified as healthy at the country of origin and will likely face an inspection—but how likely? Should we therefore tighten up inspections at the port of entry?

Developing ash trees that prove resistant to future strains has not been that successful so far. Up to 90% of UK ash trees are still at risk of infection. I understand from the Tree Council’s toolkit that only a third of local authorities have signed up to tree strategies. I believe that this should be increased.

Finally, as my noble friend Lord Caithness asked, what is the current funding for the tree strategy and the prevention and control of tree diseases? Will the Minister ensure that FERA has all the tools that it needs at its disposal to ensure that it can keep controls and innovation up to speed to protect us from future infections and diseases from other parts of the world?
