Protecting and Restoring Wetlands

Trudy Harrison Excerpts

Wednesday 31st January 2024 Commons Chamber

[Siobhan Baillie]

I do. I will come on to the fight against climate change, because the hon. Lady is absolutely right. She speaks about Somerset. Investment of £20 million, I think, went in for flood resilience work, and there is work going on with farmers. The expertise she speaks to can be sold around this country and exported around the world, so I am excited that she is able to speak so fondly of that.

With volunteers in mind, I want to speak to the current situation with our wetlands. I send love, respect and absolute hugs to all the Slimbridge volunteers; we could not do the conservation work without them. It is a sad fact that for centuries we have not been looking after our wetlands; there has not been that love and care that everyone in the Chamber wants for them. A staggering 75% of our UK wetlands have been lost over the past 300 years—this is not just a recent thing—and while the rate of decline is now slowing thanks to a lot of the work that is going on, the precious few wetlands that remain are under considerable pressure. They are in a poorer condition than we would like, and we think we could do much more work. I will speak briefly about what we should be focusing on now and in the coming months.

I would welcome a renewed push on four transformative steps that would speed up the progress on creating and restoring 100,000 additional hectares. I invite everyone in the Chamber to join the all-party parliamentary group for wetlands and join the fight, because it is crucial to achieving the net zero target. I would like action, but I will also take manifesto commitments.

[Trudy Harrison (Copeland) (Con)]

Before my hon. Friend comes on to her priorities, may I just set out how impressive she has been in persuading me, as a former Minister, and colleagues across the House of the wonderful benefits of wetlands? We are all more knowledgeable thanks to her and the work of WWT in her constituency. As well as the benefits for climate change and biodiversity, does she recognise the benefits to our health? Our mind, body and soul can really appreciate the value of spending time in green and blue spaces. As there seems to be some competition, let me say that I have 32 miles of coastline and many lakes—a wetland in the English Lake district. The benefits to our mental and physical health must not be underestimated. A wetland can be just a pond, and the 30 million gardeners across this great land can also play a significant part.

[Siobhan Baillie]

Absolutely right. My hon. Friend is a keen walker and gets out into the environment as much as possible. To be beside water is a particularly tranquil experience for most people and that is certainly something WWT campaigns on, because we know the benefits.

I ask the Government to commit to a national strategy for UK wetlands. Most of the work has been done, so let us label it as a national strategy and pull it all together, because the Department for Environment, Food and Rural Affairs is doing some great work. I would like to see a dedicated domestic wetlands team at DEFRA, to ape the success of the peat team, who are brilliant experts. If I cannot have a whole team, I will take a named civil servant we can go to who really owns all the different moving parts, because I know it is in lots of different parts of the DEFRA family.

I would like to create a nutrient offsetting code to rebuild investor confidence in that market, and to provide guidance and training for national flood management to ensure that land managers, councils and practitioners can take advantage of those options. I would like the creation of a saltmarsh restoration grant scheme, as has been done for peatland, and to scale up saltmarsh creation through the nature for climate fund. I would like a requirement for new developments to include sustainable urban drainage systems. We believe schedule 3 to the Flood and Water Act 2010 should be enacted—I have spoken to that in this place on a number of occasions. As I have said, however, plenty of very good work has been done, and I think we should talk about it more and perhaps pull it all together, because wetlands are nature’s secret weapon.

I recall that when my hon. Friend the Member for Copeland (Trudy Harrison) came to Slimbridge, we had a mic-drop moment when the experts explained that wetlands can store 18 times more carbon than trees. While a tree takes 10 years to reach its full “pace”, with wetlands the process is instant. I think that the slogan for wetlands should be #justaddwater—for environmental clout, for wellbeing, for flood defence, for carbon storage and for water quality. I understand that the Minister will speak about some of the work that the Government are doing, because there is an awful lot of it, but I think that if there had been more awareness of what is going on, we would not have seen the nutrient neutrality drama and some of the firefighting that Ministers were having to do. So much work was actually there, but no one had mentioned it. I think that home-builders are already getting there; we just need to light the touch paper and let everyone run.

There is a great deal more that I could say, but you have a life to get back to at some stage, Mr Deputy Speaker, and I know what long hours you work. Let me just mention the powerful benefits to British wildlife. I think that there is too much talk of targets and carbon in this place, but people “get” species and wildlife. In the UK, wetlands cover only 3% of the land, but they support 10% of its species. It is clear that we can scale up biodiversity and other support if we invest, think it through and protect our wetlands.

Let me say a little about flood resilience. The Government’s green recovery challenge fund helps projects such as the WWT’s Two Valleys: Slow the Flow, which demonstrates the effectiveness of using natural flood management to stop flood pressure on properties downstream. That is happening in Somerset, but I know that work of this kind is taking place in local authority areas all over the country. Let us bring it to life and end the devastating impacts of events such as Storm Henk, which we saw recently. Let me also say something about water pollutant filters. I know that in her previous brief the Minister worked extraordinarily hard on the problem of sewage and the Victorian networks that we are trying to repair, but we now know that specially engineered wetlands called treatment wetlands have the potential to remove up to 60% of metals, trap and retain up to 90% of sediment run-off, and eliminate 90% of nitrogen; so we can use wetlands to remove pollutants from water.

As for the point that has been made about physical wellbeing, spending just 10 minutes in urban wetlands has been shown to yield extensive improvements. I urge everyone to go down to Bridgwater and observe the juxtaposition of the big high rises and the wetlands that have been created, which people have been using throughout covid and beyond.

The Climate Change Committee has stressed the importance of protecting and restoring saltmarsh and seagrass because they are so efficient at carbon removal. In the long term, saltmarshes bury carbon 40 times faster than woodland. I know that the Government are obsessed with trees because we can count them, and we like things to be measurable, but there are other options. Let us do the trees, but let us do the wetlands as well.

The WWT has a superb Blue Recovery Leaders Group of businesses which have backed this initiative because they can see the economic benefits and want to invest in the environmental power of the country. Companies such as Aviva have invested a massive amount because they can see that this stuff works for their customers, for their employees, and for the country and beyond. In short, wetlands have nature-boosting, flood-busting, carbon-sinking, mood-lifting, water-cleaning superpowers, so why are we not making more of them—or, rather, even more of them, because I know exactly how much work the Minister and others are doing in this regard?
