Predators might be rats or cats, so the management of islands where puffins choose to breed, and where human activity has brought threats onshore, is vital to puffins’ safety. The Farne islands are now managed by the National Trust and a team of rangers based on the islands all summer to monitor and protect this vital habitat. The islands sit within the Northumberland marine special protection area and are now included in the latest set of UK conservation zones. The trust has monitored numbers on a five-yearly basis for decades, and the 2018 census showed some 44,000 pairs of puffins, up from 40,000 in 2013, so Northumberland colonies are in great health at the moment. The National Trust has been doing this monitoring for more than 50 years, which has helped us to keep abreast of colony size and to work out, where there have been drops, what might be causing them. It is great news that the trust now plans to monitor numbers formally on an annual basis to help inform the climate change debate as fully as possible.

Only at the end of last week, puffins were again in the news. The item referred to water temperatures rising with climate change, threatening the puffins’ continued existence. Their mainstay diet of small fish such as herring and sand eels are themselves not exempt from environmental changes and human intervention, in addition to the ongoing problem of plastics polluting our seas.

I hope my right hon. Friend the Minister will be able to give us an assurance that when the Government address climate change and marine pollution, they will not forget not so much the flight of the puffin as the plight of the puffin.

I commend and congratulate my hon. Friend the Member for Berwick-upon-Tweed (Anne-Marie Trevelyan) on securing this very interesting, useful and practical debate. On a day when so many of us, from across the House, have been meeting constituents and talking about the strategic challenge of climate change, we have an opportunity now to discuss one very small aspect of it that is nevertheless very important, because part of thinking about our responsibilities and responding to the challenge of climate change is thinking about what more we can do to protect our natural environment.

When innovative approaches to MPA management planning are being trialled, it is extremely important to work with local communities and other stakeholders to develop them. The examples I have just given show excellent partnership and collaborative working practices. Marine Scotland is also leading a research programme that focuses on Scotland’s seas. It includes work that the Scottish Government are funding to better understand the potential environmental impacts of marine renewable energy.

Puffins are an indicator species. While they are at risk from birds of prey, the biggest threats to their population are man-made. Pollution, overfishing and, perhaps most significantly, climate change are all reducing the population. I was struck by the comment made on the excellent BBC “Landward” programme by an RSPB warden in the Northern Isles at the weekend. Commenting on the distance that puffins have to travel for their food, she likened it to having to travel for Glasgow for her tea and then back again. That is not sustainable, and numbers will suffer.

It is true, as we have heard, that human activity is affecting the habitats of many of our planet’s valuable wildlife species. Through irreversible climate change, habitat destruction and biodiversity loss, we are making the survival of species that we love and appreciate increasingly difficult. In a debate last month, we heard about the cruel practice of the netting of bird nesting sites, preventing sea birds from nesting on some cliff faces. In that debate I made it clear that we must not keep squeezing nature into smaller and smaller spaces. Given what we have heard about puffin habitats, they are already in very small spaces geographically.

I am very pleased that the House recently agreed to Labour’s motion to declare a climate emergency, after an important debate that showed that this place is taking climate change seriously. I know that hon. Members from all parties will have visited climate change protesters at the Time Is Now climate protest today. Although we need to decarbonise our economy, we must not think of climate change as being only about carbon; we need to think equally about how to protect and conserve coastal habitats, bird nesting sites and feed, as we have heard today.

17:04 The Minister for Agriculture, Fisheries and Food (Mr Robert Goodwill)

Puffins are a key part of the marine ecosystem and good indicators of the overall state of the marine environment, including the damaging effects of climate change. That is because their diet consists mainly of small fish, particularly sand eels, whose spawning season is affected by variations in sea temperature impacting upon their own prey of plankton. The puffin breeding cycle is less adaptable. If the sand eels are not available at the time that puffins are breeding, it affects how many birds breed and how many chicks they raise.

In 2000, our friends in the Scottish Government implemented a sand eel fisheries closure in an area off the east coast of Scotland to preserve this important food source for our seabirds. Other pressures on puffins related to climate change include the increasing frequency and intensity of storms, which have had a considerable impact. Indeed, in the winter of 2013-14 a succession of severe storms resulted in 54,000 seabirds being washed ashore, over half of which were puffins. This mass mortality had a serious knock-on effect on the breeding population.

We recognise the importance of protecting the marine environment and we see the health of the ocean as key to tackling climate change. We have already exceeded the current global sustainable development goal to protect 10% of our marine and coastal areas by 2020, with 25% of UK waters currently protected. At the UN General Assembly in New York in September 2018, the Secretary of State for Environment, Food and Rural Affairs called for 30% of the world’s oceans to be marine protected areas by 2030.

The hon. Gentleman also mentioned sand eels, which I would like to say a little bit about, because they are an important component of marine food webs that provide food for many species of marine predator, such as seabirds, mammals and fish. The sand eel life cycle is affected by climate change, as warmer seas have a direct effect on plankton. The puffin breeding cycle is less adaptable, so if the sand eels are not available at the time puffins are breeding, that affects how many birds breed and how many chicks they raise. We also know that that varies annually, and in different parts of the country.

The RSPB’s citizen science project, Puffarazzi, is currently collecting data on puffin diet to complement research being done by several academic groups, which will give us an insight into puffins’ current diet and changes over time. There is some evidence that the exploitation of sand eels affects the wider ecosystem, such as causing a decline in seabird populations. For example, a recent study has found a correlation between kittiwake breeding success and sand eel fishing mortality, although there are many other factors that could have an impact on small fish populations, such as climate change.
