If you’re taking part in No Mow May this year, then your garden will be well on its way to becoming a beautiful, biodiverse haven for nature. But there is a bonus to helping the wildflowers grow – as you allow lawn to become meadow, your garden becomes your very own carbon store, helping to reduce your carbon footprint.

When carbon sequestration is mentioned, most minds turn to trees. As a society we are more aware than ever before of the role of woodlands in combatting climate change and creating a space for nature. Much less discussed is the remarkable and equally vital role our grasslands and meadows can play in increasing biodiversity and capturing and storing carbon from the atmosphere.  

How do grasslands store carbon?

Wildflowers growing in a meadow with cattle behind

When we create healthy grasslands and meadows by mowing or grazing livestock, we are simply replicating the activity of the herds of large wild herbivores that once moved across our hills and valleys. These habitats – if the grazing is gentle, infrequent and low intensity – recreate prehistoric landscapes and provide a home for our wild plants, insects, birds and fungi. Natural and semi-natural grasslands (meaning those that are farmed but in a traditional, less intensive manner) improve the quality of our water, prevent flooding and help increase the resilience of farming to summer droughts. 

This grassland – and the healthy soil beneath it – also has an incredible and little-known potential to lock away atmospheric carbon. Soil carbon is a particularly valuable store; it is far more stable and long lasting than the carbon in trees, which is vulnerable to forest fires, pests and disease.

As plants live and grow, carbon from the atmosphere is drawn down into the plants’ roots, where the myriad creatures in the soil make use of it, locking it away beneath the ground. As the diversity of plants on the surface increases, so does the diversity of microorganisms, fungi and invertebrates beneath it. The more diverse the soil life, the richer the entire ecosystem – and the more carbon the soil can store.

The role of Mycorrhizal fungi

The almost mystical role of mycorrhizal fungi is now well known. They connect roots to the nutrients in the soil, trading sugars that plants and trees create from sunlight with locked away minerals the fungi extract from the soil. We now know that plants and trees can communicate through these fungal networks, alerting them to pests and diseases and passing nutrients to others in need.

Mycorrhizal fungi have another important role – they are critical in the ability of plants to transfer carbon to the soil. In areas of farmland, meadow and garden where the soil is ploughed, fertilised or dominated by a small number of grass species, these mycorrhizal networks are much less effective – with fewer species and a lower carbon storage potential. When we look after our farmland and gardens with care, mowing and grazing infrequently and gently, avoiding ploughing and pesticides, we nurture our mycorrhizal fungi, helping the soil to become a more potent carbon store.

How does No Mow May help?

By taking part in No Mow May, you will not only begin to create a home for wildflowers and insects, you will also create healthier soils that nourish your garden plants – and reduce your carbon footprint in the process.

England alone has around 640,000 hectares of private garden. If just a quarter of this area was transformed into wildflower rich meadow – by mowing just once or twice a year and collecting the cuttings – then these garden soils could potentially capture and store an additional amount of carbon equivalent to more than 3 million average cars’ annual emissions within a spade’s depth, and well over 10 million cars in soils as deep as one meter*.

Lawns and gardens are of course just one part of the puzzle – the UK’s farmed grassland landscape offers tremendous potential for us to sequester carbon, while also protecting agriculture and biodiversity.

Farmers and landowners have a fundamental role to play – combining food production with sustainable grasslands that lock away carbon in healthy, ecologically rich soils. Some 40% of the UK’s land area is grassland – but much of this is intensively farmed, limiting its potential for carbon storage.

Globally, studies have suggested that 2.3-7.3 billion tons of CO2 equivalents per year could be sequestered through grassland diversity restoration. Carbon sequestration doesn’t just mean more trees. Healthy grassland, with the more sensitive grazing and less intensive farming that nourishes it, also keeps carbon out of the atmosphere. 

No matter how large or small our garden, we all have a role to play, and we can all make a difference. It’s easy to get started – just put your lawnmower away this May!

How to Grow a Wildflower Meadow

Whether it’s your back garden, local park, community field or lawn, wildflower meadows are amazing spaces with so much to offer.

The 28th UN Climate Conference of Parties has just drawn to a close in Dubai, during which there had been fierce negotiations over the future of fossil fuels.

In the early hours of this morning the gavel went down and 198 governments agreed to “transitioning away from fossil fuels in energy systems, in a just, orderly and equitable manner… so as to achieve net zero by 2050 in keeping with the science”. This wording is not as strong as we had hoped, but it is the first time fossil fuels have ever been explicitly mentioned in a final agreement (in almost 30 years of climate COPs) and as the UN Climate Chief Simon Stiell said, it is the ‘beginning of the end’ for fossil fuels.

This issue is at the heart of climate action and this agreement was long overdue.

COP28 in Dubai

What else was decided?

There are other key outcomes from this COP which give us reasons for hope:

  • The first ever Global Stock Take includes references to the Kunming-Montreal Global Biodiversity Framework – the link between biodiversity loss and the climate crisis and ‘protecting, conserving and restoring nature…’ using not only science but Indigenous Peoples knowledge.
  • The newly established Loss and Damage fund, which if you will recall was implemented on the very first day of the conference, making it an historic moment. This fund now sits at $792 million which will go to developing nations in need, recognising that they have been most affected by climate impacts.
  • The Global Goal on Adaptation, designed to “ensure an adequate adaptation response” to protect people, livelihoods and ecosystems, talks about the multi-stakeholder approach to adaptation needed, using knowledge from different sectors of society.

Successes for biodiversity, food and farming

More specifically focused on the intertwined climate and nature crises, we welcome two new initiatives coming out of this COP.

1.COP28 UAE Declaration on Sustainable Agriculture, Resilient Food Systems, and Climate Action

The acknowledgement and recognition of the adverse impacts of climate change on agriculture and food systems, and on billions of people including smallholders that are dependent on their resilience for food and livelihoods, is a great step in the right direction. Just two years ago, there was little or no mention of this issue, yet 158 governments endorsed the Declaration at COP28.

2. COP28 Joint Statement on Climate, Nature and People 

This was an absolutely vital step in ensuring the climate and biodiversity crises are no longer considered as separate issues. We have known for a long time that they are fundamentally and intrinsically linked, and this is the first step in connecting the outcomes of the UNFCCC COP28 and the recently adopted Kunming-Montreal Global Biodiversity Framework.

This announcement was made: ‘At COP28 during Nature, Land Use and Ocean Day, we affirm that there is no path to fully achieve the near- and long-term goals of the Paris Agreement or the 2030 goals and targets of the Kunming-Montreal Global Biodiversity Framework without urgently addressing climate change, biodiversity loss and land degradation together in a coherent, synergetic and holistic manner, in accordance with the best available science.’

Eighteen governments have endorsed this declaration so far and we need to see many more signing up to this joined-up approach in the weeks ahead.

We’re going to keep talking about grasslands

At Plantlife, we work tirelessly to bring the value of grasslands to the forefront of conversations around farming, nature, biodiversity and climate, both in the UK and internationally. Covering more than half the Earth’s land surface and with the livelihoods of around 800 million people depending on them, the importance of grasslands and savannahs cannot be underestimated.

More generally, this COP marked a turning point for the role of Indigenous Peoples and the recognition of their contribution in not only safeguarding 80% of the world’s biodiversity, but their knowledge in living in true harmony with nature. Adopting this way of thinking will be a pivotal step in combating the climate crisis. Plantlife is aware of the importance of Indigenous knowledge particularly when it comes to Important Plant Areas (IPAs), with one of the criteria for identification being related to cultural significance.

You can read more about IPAs here specifically the Chiquitano people of Bolivia who identified 18 IPA sites to protect the Chiquitano dry forest which many of the community depend on for their food and livelihoods.

It is safe to say there was a healthy dose of concern and scepticism about this COP. What would come out of it? Would this be ambitious enough to secure a safe future for generations to come – from large cities in the Global North to the Small Island Developing States on the frontline of the climate crisis? The reference to fossil fuels and the language in the final text can be considered a win, but now we look to parties to solidify the ‘how’ and the ‘when’ of implementing the measures to ensure we stay at or below 1.5 degrees of warming.

One thing is crystal clear: we are at a pivotal moment, for the stability of our planet and all life on Earth, and Plantlife will keep working to show how wild plants and fungi can be at the heart of the solution.

As I write this, I’m eating a piece of toast. As you read this, you may be eating something too. All 8.1 billion of us need food. Just like other types of consumption, such as oil and gas, our food consumption requires and releases energy. In fact, the food system is responsible for more than a third of greenhouse gas emissions caused by humans.

Why we’re all talking about food

It therefore makes sense that food is a central focus of the climate Conference of the Parties (CoP28) taking place at the moment in Dubai.

The CoP28 theme today is ‘Food and Agriculture’, which is a good opportunity to put down my toast and highlight some of the food and agriculture discussions at CoP28, and what they mean for wild plants and fungi.

Wild plants and fungi – not just for lunch, but for climate

We rely on wild plants and fungi for so much, however they are the overlooked centrepieces at the heart of all ecosystems.

Take grasslands: the livelihoods of around 800 million people depend on them and they cover more than 50% of the world’s land.

Imagine nomadic reindeer herders navigating the Steppes in Mongolia, or small-scale pastoralists grazing their livestock on Kenyan savannahs. Humans are part of a virtuous Venn diagram, with grasslands at the centre:

  • food is produced from the livestock
  • the livestock provide the grazing needed to maintain a balanced grassland ecosystem
  • the healthy ecosystem stores carbon and is also more resilient to the impacts of climate change

But not all agriculture is equal…

It’s important to differentiate this approach to grassland management from the more intensive farming, that shatters the mutualistic relationship between people and the natural environment.

Intensive, large-scale agriculture relies on greenhouse gas-emitting synthetic fertilisers and ploughing, with tightly packed livestock damaging the sensitive flora and degrading the soil.

That’s why we’re looking to world leaders at CoP28 to recognise the value of healthy grasslands and savannahs as part of a sustainable food system, that helps boost biodiversity and tackle climate change.

We need joined-up action across governments and their policies tackling farming, food security, public health, nature & net zero.

CoP28 announcement

At CoP28, 134 countries have signed up to the United Arab Emirates Declaration on Sustainable Agriculture, Resilient Food Systems, and Climate Action, committing to integrate food into their climate plans by 2025.

This could be an important step towards real action to bring down emissions from global agriculture, in tandem with supporting farmers, pastoralists, and smallholders who farm in a low-carbon way.

However, alongside real action there’s also real risk – of greenwashing. We should be sceptical of subsidies that still go towards funding intensive agriculture, or untested technological solutions to reduce greenhouse gas emissions.

We’ll be watching how governments put this Declaration into practice.

Food for thought

Of course, it remains to be seen whether governments will make tangible commitments to actually shift food production away from intensive agricultural practices.

Will governments stop harmful agricultural subsidies and instead pay and support less intensive farming, that helps restore swathes of degraded grassland?

Will they ignore the huge farming and fertiliser lobby to help farmers break free from costly input cycles?

Will the rights of indigenous people and local communities to their land and traditional pastoralism be respected?

We want the protection, sustainable management, and restoration of healthy grasslands to be meaningfully incorporated into countries’ climate and biodiversity strategies.  

As I finish my meal, these are the questions I will ponder ahead of CoP28’s final few days. The solutions to the climate and biodiversity crises are by no means bitesize, but I have hope, if we’re all sat together at the same table.

‘I used to do lots of cultivating, reseeding, and fertilising. This impacts wild plant species and soil health, and releases greenhouse gases. I also realised that they were only short-term fixes and never really paid for the cost of the stress and inputs. Often as a farmer you feel you need to be producing at all costs, but financially, the cost of bought-in inputs has increased way past them being affordable.


Why I changed the way I farmed

I changed the system five years ago, after a conversation with a Civil Servant who said that, in the future, farmers would be paid for more nature friendly farming. The transition was challenging, both financially and mentally: the peer pressure to keep farming conventionally was huge.

Post-war the mindset was all about production, and tenant farmers would have lost their farms if they didn’t meet demands. This doctrine has influenced generations of farmers since. It’s meant we’ve lost the connection between how and why we produce the food, and we sometimes forget the benefits of wildlife within the farm system. 


What sustainable farming methods mean for wild plants

Hywel Morgan standing by a pond with trees behind him

Making the change has meant a large reduction in costs and I can see – and enjoy – the benefits of working with nature.

I try to keep everything simple. I have cut out chemicals and fertilisers. This helps to reduce soil fertility and then encourages the growth of wildflowers and other grasslands plants that need low nutrient levels. I’ve seen many more Birds-foot Trefoil, Yellow Rattle, Yarrow, and Plantain since making the change. I’ve also got loads of different species of waxcap in my fields now, some are even of regional importance.

My hedges are now allowed to grow taller and thicker, and only trimmed every three years. I have also planted a lot of trees and hedging over the last few years and created large pond.

Farming livestock right can benefit biodiversity

Plants need recovery time after grazing so they can flourish. To allow this to happen I now do mob grazing, which is moving cattle in short bursts of high intensity grazing, and bale grazing, which is allowing livestock to feed off a whole, intact bale of hay. I have cut out bought-in feed apart for some hay, and focus on producing high quality, pasture-fed livestock.

I needed a better balance between grazing types, because sheep and cows graze in different ways, so reduced sheep and increased cattle numbers. Without the right management, sheep will nibble out pretty much everything, cattle graze in a less destructive way and are generally better for biodiversity. I’m always working to find out what balance is right for my land.

Nature friendly farming should just be ‘farming’


Government policy should reward smaller family nature friendly farms – it’s a reward for doing good things that benefit all of us. Banks and supermarkets need to support this move too as healthy nutritious food is part of the solution for climate, environment and peoples’ health. More farmer-to-farmer advice and support regarding regenerative agriculture is also needed to move to a sustainable future.

Achieving food security means eating locally and seasonally and certainly, we can’t have a stable food system when nature is in decline. I believe nature friendly farming should just be called “farming” and anything else should be called industrial or chemical farming.’

What’s new in Plantlife’s agricultural work

Many of our upland and lowland landscapes in Wales are dominated by green fields. In fact, 83% of our farmed landscape is managed as permanent grassland or for rough grazing. Our future agri-environment schemes will be a vital part of paving the way to restoring these landscapes. As a result, Plantlife have been working hard on our response to the Welsh Agricultural Bill and the Sustainable Farming Scheme Proposals for 2025. 

Challenges faced by Permanent Grasslands in Wales 

Permanent grasslands (those not regularly ploughed or reseeded) are often overlooked in climate change mitigation. However, they are a key nature-based solution to the challenges we face. One reason they get so overlooked is a lack of collective knowledge about grassland soil carbon.  They are also side-lined by an emphasis on tree planting and peatland restoration in policy. Effective management of permanent grassland is at the heart of Wales’ livestock production and the wider farming economy. We need it to be at the heart of addressing the climate and biodiversity crisis as well. 

Benefits of permanent grasslands 

Grasslands are incredible habitats, which can sequester and store carbon, and improve biodiversity. They provide natural flood defences, enhance our health and wellbeing, lock up pollutants. Importantly, they also sustain an irreplaceable part of Wales’ cultural heritage.

Plantlife’s work in permanent grasslands in Wales

At Plantlife, we would like to see greater recognition for the multiple benefits these grasslands can provide. We are asking Government to support farmers and land managers to adapt their farming practices. Also, for the government to assist farms to restore and maintain species-rich grassland. Unfortunately, in the past, grassland restoration has seen lower payment rates compared to, for example, the support for arable farms. The new scheme needs to be economically viable for all farmers to enter. It will be important that there is good advice for farmers and land managers to access, apply and manage these schemes. 

Working with local farmers around Cae Blaen-dyffryn nature reserve 

As well as putting pressure on Welsh Government to do the best it can for our farmed environment, we are also working towards restoring agricultural grasslands ourselves. 

Hywel Morgan has recently joined the Plantlife Cymru team as our Agricultural Advisor. He will be working in the landscape around our Cae Blaen-dyffryn nature reserve, near Lampeter. He is speaking to local farmers and seeking to understand where the most mutually beneficial and sustainable actions for grassland conservation lie.  

We hope that over time, we can work a lot more with this farming community. Plantlife will be seeking funds for the grassland restoration based on opportunities we identify. Hywel’s brings personal knowledge of farming and will gain local insight from speaking to the farming community. This will help us to advocate for grassland restoration solutions that have the best chance of success. 

Stay tuned to our blog and sign up to our newsletter; Hywel might share his insight what he learnt from talking to the local farming community.
