Far too often, the world’s wild plants have been relegated to the green background for more charismatic wildlife…but no more.We’re thrilled that the Global Strategy for Plant Conservation was adopted at COP16. Just returned from Cali, Colombia – our Global Advocacy Officer Claire Rumsey tells us more.
As the 16th Conference of the Parties (COP) to the Convention on Biological Diversity (CBD) came to a close in the early hours on Sunday morning, we were thrilled to hear the news that the new Global Strategy for Plant Conservation (GSPC) was officially adopted.
Far too often, the world’s wild plants have been forgotten and we’ve been calling to bring them to the forefront of global conservation efforts.
The adoption of the GSPC (and its 21 complementary plant conservation actions) in Cali, Colombia is a big step forward. It means a commitment to align plant conservation efforts with the Kunming-Montreal Global Biodiversity Framework (KMGBF), which is an international agreement made up of ambitious goals and targets to combat biodiversity decline. This includes updating the GSPC with specific indicators and a standardized reporting template, ensuring that progress in plant conservation is measurable and consistent with global biodiversity targets.
A Fungi Pledge was also put forward, which we were absolutely thrilled about. The pledge, lunched at a side event by the UK and Chilean Governments proposed that the CBD introduce a ‘fungal conservation pledge’ to better prioritise fungi in global conservation strategies.
This is great news for fungi. We are starting to see much more profile and attention given to the fungus kingdom and we will be seeking opportunities to work with the fungus community to build on this momentum.
In a truly historic decision, COP 16 delegates agreed to create a special advisory board for Indigenous Peoples and local communities (IPLCs).
This means that the voices and knowledge of IPLCs will be an integral part of the future of biodiversity and nature conservation decision-making.
Pre-COP there was general acknowledgement that this COP must strengthen the role of Indigenous Peoples and local communities, who are “the world’s great guardians of biodiversity, luminaries of sustainable use”. And this decision, has done just that!
This COP had big shoes to fill, being the first one since the landmark KMGBF was adopted in Montreal in December 2022, hailed the Paris Agreement for Biodiversity.
There was more interest than has ever been seen in a Biodiversity COP; we were among a whopping 23,000 other registered delegates, the High-level Segment was attended by six Heads of State, more than 130 Ministers and Vice Ministers, and over 70 leaders of international organisations.
And, staying true to its title of ‘the people’s COP’, for the first time ever in a CBD COP there was a Green Zone (differing from the Blue Zone where the negotiations take place), located in the centre of Cali, constituting an open fair for biodiversity, and attracting around 40,000 people daily. This felt like the true COP, vibrant, full of energy and lots of public engagement with the stalls and activities. Check out our video here.
Our week was (as you’d expect) lots of non-stop talking about plants, fungi and biodiversity. At the conference itself, we shared a booth with Botanical Garden Conservation International (BGCI) creating a hub for discussions of all things plants (and fungi).
We were there, to quite literally wave our (pink!) flags for plants and fungi, and the Global Partnership for Plant Conservation (GPPC). It was very busy and incredibly worthwhile.
Another common thread of the COP was the implementation of a ‘whole of society’ approach to conservation, which we at Plantlife have been encouraging for years. This, for us specifically meant emphasis that it is not the sole responsibility of botanists and botanic gardens to speak up for plants (in the form of these new actions), but all different sectors – the farmers, the foresters, the businesses, IPLCs, national and global NGOs.
We had fruitful and fascinating conversations with new and old friends including New York Botanic Garden, IUCN’s Reverse the Red, Key Biodiversity Areas, the Crop Trust and the IUCN’s Global Species Action Plan. And we connected with people from Mexico, Nepal, California, Switzerland, and Ruth Davies popped in to say hello as the new UK Nature Envoy (a former Plantlife employee and still a big Plantlife fan!).
Our Director of Conservation, Nicola spoke at the GSPC side event about how these new plant conservation actions will contribute not only to the implementation of the KMGBF, but also multiple other UN frameworks and global policies. It was clear this is a moment for plants!
Now that we’re back and the GSPC has been formally adopted, we can follow-up on the numerous connections we made, continuing to strengthen and grow our global network.
We will continue to advocate for the GSPC, particularly beyond the botanical garden world, so that we widen the understanding of the value and relevance of the plant actions and push for a broader societal to apply the actions within their own programmes and activities. Our aim is to make information more accessible and useful and to help bridge the gap from the science to conservation action on the ground.
Currently, a list of threatened and range-restricted plant species is being refined in New Guinea as part of the Tropical Important Plant Areas (TIPA's) project (2022-2024).
In Mozambique 57 IPA's have been identified, which is being used as focus for the Tropical Important Plant Areas team.
Recent studies have revealed that there’s so much fungi out there that we don’t know about.
But how do we know this? Plantlife’s Rachel Inhester, from our science team, tells us why.
This incredible fact from the Kew report, ‘State of the World’s Plants and Fungi 2023’, highlights just how much there is to learn when it comes to fungi. That was certainly my first thought when I read this statement. It’s exciting to think of all the discoveries we have yet to make, and it gives an indication as to the huge amount of work ahead of us, to find and classify such a large number of unknown species. The report goes on to estimate that there are between 2-3 million species of fungi in the world, and as of yet, only 155,000 of those species have been formally named!
Fungi can be difficult to detect for a number of reasons:
As I was contemplating just how little we know about these extraordinary organisms; another thought came to mind. How can we estimate that 90% of fungal species are unknown to science? How did we come up with that number? In other words, how can we know what we don’t know?
Well, it turns out, that to arrive at such an estimate, you first need a team of fungal specialists, known as mycologists, and then you need the time and capacity to critically evaluate all the current knowledge on the topic so far. It was certainly no simple undertaking!
Past methods of calculating the number of fungal species, were not without issue, so the team of experts definitely had their work cut out for them. Previous estimates couldn’t be completely relied upon on their own. Sampling techniques varied and some fungal groups were not considered in certain studies. Some reports were simply outdated due to the discoveries that have been made since they were first published.
It’s important that we try to speed up this process so that we can understand the fascinating world of fungi around us. Fungi are interconnected with nearly all life on earth. They can improve nutrient uptake of plants, improve the immunity of their plant hosts against pathogens, they are biomass decomposers, and some species are used to make medicines [1].
The team of specialists decided to focus on 4 key academic areas to better estimate the number of expected species. These research areas were scaling laws, fungus to plant ratios, actual vs previously known species and DNA based studies.
Organisms are classified into 8 main levels or ‘taxa’. From highest to lowest, these taxa are: Domain – Kingdom – Phylum – Class – Order – Family – Genus – Species. This is a way of organising organisms into groups which become more inclusive with every level. Let’s use the Fly Agaric fungi as an example. At species level we simply have Fly Agaric (Amanita muscaria). The Fly Agaric is an individual species, but individual species can belong to a larger group, or genus, in this case the genus Amanita. A genus is a grouping of similar species which all share a common ancestor. The groupings, or taxa, get progressively larger as you move up each level until you reach the levels of Kingdom and Domain. The Fly Agaric is part of the Fungi Kingdom which includes all other fungal species.
Scaling law studies aim to predict species diversity by looking at patterns in the numbers of ‘higher taxa’ and the number of known species in each.
In this case, information from the level of phylum (the third taxa) to genus (the seventh taxa) was used. Patterns in the numbers of these ‘higher taxa’ were compiled to predict fungal species diversity. Previous studies were assessed by the fungal experts, who adjusted the estimates to include recent discoveries and accurate numbers of known species.
Fungus to plant ratios have been estimated in multiple studies over the years and for a variety of habitats. Therefore, if we know the number of plant species, we can make a pretty good estimate as to the number of fungal species.
However, the fungal experts were still faced with challenges when examining previous research. Studies varied in how they calculated the ratios to begin with. Some only considered fungi with a known association to plants and other studies were much broader. Coupled with the fact that lots of fungi can be difficult to detect and may have no association with plants whatsoever, a lot of the predictions were considered an underestimate. On evaluating earlier research, the specialists felt that a ratio of 5:1, of fungi to plant species, in temperate areas and 4:1 in tropical locations, was more accurate than previous estimates.
Some species of fungi can be difficult to differentiate. This can cause an underestimation of species numbers as multiple species are occasionally classified as one and the same. The fungal experts examined a study which had investigated this in detail where they concluded that there were 11 times as many actual species compared with previously known species. Varying definitions of exactly what a species is, creates difficulty with this method of estimation.
DNA based methods have been an incredibly powerful tool in documenting fungal diversity around the world. A single sample can allow scientists to sequence the DNA of whole communities of fungi. These samples can come from a variety of places, including soil and deadwood. The samples are then analysed and any DNA within the sample is extracted and sequenced.
This DNA gives us a list of all the fungal species found in a sample, including species which we can’t even see, providing us with a more accurate representation of fungal species numbers.
For Kew’s report, it provided the final piece of the puzzle in answering the question of ‘how many species of fungi do we think there are globally?’.
Using all the information and research available to them, the fungal experts refined their predictions and came up with an estimate of 2.5 million species of fungi worldwide! [2]
So there really was a lot of work that went into this seemingly impossible estimation. As it stands, this estimate reveals how many species we have yet to discover.
At this time, around 2,500 new species of fungi are identified and described each year. And if the above estimate is accurate, that would mean waiting 750-1000 years for us to find and describe the rest. [2]
As we discover more species, we shall hopefully uncover more benefits of the fungi around us, as well as conserving as many species as possible before we potentially lose them forever.
Fungi underpin the health of our environment and are key to resolving the climate, ecological and societal challenges we face. Your donation could help increase understanding of fungi and get them the support they need.
For a full dose of positivity take a look through our 2024 highlights. Let's revisit the amazing ways we have helped protect nature for the future this year.
Getting out and looking for fungi can be a great way to connect with nature and discover more about this amazing kingdom. Here our Specialist Botanical Advisor, Sarah Shuttleworth, gives her top tips for finding fungi!
We’re thrilled that the Global Strategy for Plant Conservation was adopted at COP16. Just returned from Cali, Colombia – our Global Advocacy Officer Claire Rumsey tells us more
The peat-rich Flow Country, which our Munsary Peatlands are part of, has been given the same standing as the Great Barrier Reef and the Grand Canyon.
This marks a special moment for Scottish wild plants, fungi and the wildlife that call it home.
With the same standing as the Pyramids and the Great Barrier Reef, The Flow Country has been granted UNESCO World Heritage Status – marking a magnificent moment for Scottish wildlife.
Deep within this historic landscape is our own Munsary Peatlands, which is an incredibly special place for plant life. One of the most extensive peatlands left in Europe, our Munsary Nature Reserve is key for tackling the ongoing climate crisis.
Alistair Whyte, Head of Plantlife Scotland said: “The Flow Country may be less well-known than the Great Barrier Reef, the Grand Canyon and the Pyramids but it is cause for great celebration that it today has achieved the same standing as those rightly revered places on Earth. Recognition of the special significance of this wet and wild habitat in northern Scotland, where ancient peat can be as deep as a double-decker bus, demonstrates a growing recognition of the importance of peatlands to plants, people and planet.”
This historical moment also means the Flow Country has become the world’s first peatland World Heritage Site.
After years of hard work, we are thrilled that The Flow Country, in northern Scotland, has been designated as a UNESCO World Heritage Site – a special moment for Scottish wild plants, fungi and the wealth of the wildlife they support.
UNESCO (The United Nations Educational, Scientific and Cultural Organisation) seeks to encourage the identification, protection and preservation of natural and cultural heritage around the globe considered to be of outstanding value to humanity. What makes the concept of World Heritage so special is its universal application. World Heritage sites belong to all people, irrespective of where they are located.
The list of World Heritage Sites is as varied as the Great Barrier Reef in Australia to the Pyramids of Egypt – and now that list includes the Flow Country of Caithness and Sutherland, located near Lybster in Scotland (among just over 30 sites currently in the UK).
Munsary, a vast and undulating plain of blanket bog, is home to a huge variety of wildlife including some rare and threatened species.
This historic landscape is the most intact and extensive blanket bog system in the world. As well as being very important for biodiversity, it is also classed as an Important Plant Area (IPA). IPAs are key sites for exceptional botanical richness and identified as the best places for wild plants and their habitats.
So far, 147 species of vascular plants have been recorded at Munsary including the nationally-scarce Small Cranberry and a patch of Marsh Saxifrage, discovered in 2002, which is one of the largest colonies in Britain. The reserve in Caithness is also home to a Bog Orchid, a tiny yellow-green orchid which is so slight as to be almost invisible in the few bogs where it grows.
But, healthy peatlands – like Munsary – are more than just wildlife havens; they also have a vitally important role as we tackle the climate emergency. In fact, the vast expanse of pristine peat formed over many millennia at Munsary locks up a staggering two million tonnes of carbon.
Some species to look out for inlcude:
A special feature at Munsary is an unusual-looking area of dark-watered pools, high on a dome of peat, called dubh lochans. This area is particularly diverse, with pools of different shapes, sizes and depths, vegetated pools, and open water, ridges, and hummocks.
Even a visitor who has never studied mosses can spot differences between those forming the peat. Some form neat, rounded mounds, others are brownish or reddish tufts, while others make a deceptive green lawn, floating over water of an uncertain depth.
The drier areas of bog moss are home to many characteristic bog plants: Bog Asphodel, with spikes of yellow flowers, Common Cottongrass, with many white cottony heads in summer, and hare’s-tail cottongrass with just a single, fluffier head. Three species of heather grow here and plenty of sedges too, including such hard-to-find species as few-flowered sedge, flea sedge and bog-sedge.
Insect-eating plants lurk beside streams and wet pools: butterwort, with a basal rosette of broad, yellow-green leaves on which small insects stick, and round leaved and great sundew, with long red hairs on their leaves curving over to entrap their prey.
Peatlands are home to some of the UK’s most distinctive plant communities – they have evolved in response to the low-nutrient conditions. This has led to some remarkable adaptations such as the insect-eating sundews and butterworts, and the spongy blankets of colourful spagnum mosses.
They are also one of our most important terrestrial carbon sinks. But when bogs are drained or the peat is exploited, the peat gets exposed to the air and begins to break down, releasing carbon dioxide. This turns a huge carbon store into a vast emitter, contributing to climate change. Read more here.
As the UK’s new government ministers settle into their new departments, we are calling for action to preserve and restore nature for wildlife, people and the climate.
What the government does in its first 100 days can pave the way for five years of new policy. By acting now to protect and restore nature, the government could transform the fortunes of wild plants and fungi.
We’ve sent a letter to the Secretary of State calling on the government to commit to a Grassland Action plan, establish a National Rainforest Fund, legislate to end peat sales and show global leadership in species recovery.
With 2 in 5 plant species at risk of extinction, biodiversity loss is now the fastest it’s ever been. This means our work has never been more vital.
We would like the new government to:
The ultimate multi-taskers, grasslands rich in wild plants and fungi can sequester and store carbon, clean our air and water, and produce sustainable food.
From farmland pastures to urban road verges – grasslands cover more than 40% of England’s land. Unlocking their economic and environmental benefits, as part of a circular economy, will support communities, local authorities and national agencies.
But the majority of our wildlife-rich grasslands have been destroyed and the losses are continuing.
We need the government to take a strategic approach, starting with the establishment of a Defra-led Grassland Taskforce to understand the social, economic & environmental potential of this national asset for people, the economy, nature and climate.
England’s temperate rainforests are of global importance, with the greatest concentration of oceanic lichens and mosses in Europe. These lower plants are ancient and pre-date humans, flowers and even dinosaurs.
But these habitats are rare, highly fragmented and facing multiple threats.
Whereas previous government plans to recover England’s temperate rainforests lacked ambition and commitment, we need a more far-reaching and detailed approach to help these precious habitats thrive.
Creating a National Rainforest Fund, to attract both private and public investment, will support long-term landscape-scale restoration, reduce external pressures and engage landowner and local communities in practical action.
Despite repeated commitments by the previous government, legislation to end peat sales is still not in place. Meanwhile, the harvesting of peat continues to destroy peatlands and their wildlife – releasing carbon and increasing flood risk.
There have been great strides in reducing peat use. Yet two-thirds of bagged compost sold in 2022 still contained some peat and total peat use for the year was 950,000m3.
With a fair, well-managed and supported transition, there is a bright, successful future ahead for a peat-free, sustainable horticultural industry. But legislation is required if this future is to be realised. To end the uncertainty that has plagued British horticulture for well over a decade and to protect our peatlands, we need to see this as a priority for the government’s legislative programme.
Fast forward to October when governments from across the world will gather at the UN CBD COP16 in Columbia, with the aim of driving global action for biodiversity forward.
This includes leading by example. We are calling on the UK government to set out its national plan, by October, for how it will meet the legally-binding targets in the Environment Act 2021 and the global biodiversity targets to 2030.
At COP 16, we need senior ministers attending and actively engaging in international collaboration for nature. By offering to host COP17 in the UK, the government will have an unmissable opportunity to show true global leadership on species recovery.
These are the critical first steps to building a healthy and prosperous society underpinned by a thriving and resilient natural environment. And as time begins to run out, we are using our position to bring lasting and positive change to our natural world – for everyone’s sake.
We hope the government will commit to protecting and restoring nature, which will help the future of wild plants and fungi, in England and across the world.
As environment policy is a devolved matter, UK government action relating to grasslands, rainforest and peat sales applies to England only.
Managing or making meadows, whether as part of your lawn or larger sites, can sometimes lead to a prickly problem, with plots of docks or nuisance nettles!
Problems can arise by opening the soil or when the nutrients are very high – but our experts are here to help.
While most plants have some value to wildlife, species such as Common Nettle Urtica dioica, thistles Cirsium sp and docks Rumex sp can spread rapidly in meadows or lawns with sub-optimal management and crowd out wildflowers. Small amounts of these species are natural in any grassland, especially along boundaries or corners, large amounts of them can indicate a problem.
However, large swathes of thistles or nettles will result in less space for a diversity of other flowering plants, which could result in a meadow being less valuable for wildlife. Also be aware that an area that has alot of these problem plants already, is usually best avoided altogether if attempting to make a new meadow area.
Preventing problem plants establishing in large numbers is better than a cure . It is best to:
Broad-leaved Dock Rumex obtusifolius can grow up to 120cm tall and has wide lower leaves that are slightly wavy-edged. The upper leaves on the flowering stem are narrower. The leaves may be slightly red tinged.
Curled Dock Rumex crispus is like Broad-leaved Dock but has narrower leaves tapered into the stem with strongly crisped edges. Docks are an important plant for a range of insects such as capsids, weevils, beetles, spiders and many other insects.
Spear Thistle Cirsium vulgare is a biennial plant, forming a rosette of spiny and sharply toothed leaves in the first year and producing large purple flowering heads in the second year.
Creeping Thistle Cirsium arvense is perennial with wavy-toothed leaves that have slender spines and smaller purple flower heads.
Common Ragwort Jacobaea vulgaris is a biennial member of the Daisy family. Its seed germinates in the autumn producing a rosette of leaves. During the second year, the plant sends up flowering shoots which have multiple yellow flowers.
Common Ragwort is known to support more than 129 other species of invertebrates and has enormous value for wildlife. It acts as a nectar source for pollinators as well as some larvae of flies and beetles which feed on the inside of the flower head. The caterpillars of the cinnabar moth eat Common Ragwort acting as a natural biological control agent. In addition, 14 species of fungi use ragwort as their host.
Common Nettle Urtica dioica is a coarsely hairy plant with stinging hairs that have a histamine-containing juice. Plants are dioecious – male or female. It has far-creeping underground rhizomes which can spread creating large clumps of common nettle.
It is an important plant for a range of insects such as ladybirds, damselflies, capsids, weevils, beetles, and spiders. Young nettles are the food plant of many moth larvae such as the snout, dot, burnished brass and younger mother-of-pearl and butterflies such as the peacock, small tortoiseshell and comma.
Many of them have seeds that are very fertile and spread on the wind, usually dropping far away from the parent plant. A single Common Ragwort plant can produce up to 200,000 seeds, and these can lie dormant in the soil for as long as 20 years. Common Ragwort is also a problem in particular for livestock as the plant contains toxic alkaloids which act as a cumulative poison eventually destroying an animal’s liver.
Some species also have rhizomatous roots that are spreading meaning that they form dense clumps in grassland. Accidently breaking up the roots when removing certain species creates larger clumps as even small bits of root can grow into plants and can remain dormant in the soil for years. For example, Creeping Thistle can create a 20- metre patch in just two years from a small bit of root left in the ground.
Spear Thistle, Creeping Thistle, Broad-leaved Dock, Curled Dock and Common Ragwort are classified under the Weeds Act 1959, under which orders can be made requiring their control to help prevent their spread. So, controlling populations of these two species should be undertaken to manage the extent of clumps as total elimination is unlikely to be achievable or desirable.
All methods of managing problem plants need patience above all else. Most often it can take years before problem plants are brought back under control.
Essentially pulling by hand is going to be the simplest and least invasive way of managing most of them, or simply cutting the heads off the plants before they flower or set seed for others. However, if you have large numbers of plants and are unable to physically remove them, then spot-spraying can be used. We would always recommend consulting an expert for suitable and available herbicides that will affect the specified problem plants and how to apply the chemicals safely. Spraying is usually most effective early in the season (May or June) before the plants’ flowers are developed. When found along the edge of watercourses, there are additional concerns about using herbicides.
It is important to take care when digging to remove some species, as Creeping Thistle for example can spread further if fragments of roots are left in the soil, whereas digging and removing Spear Thistle is not a problem.
In a well-managed sward, Common Ragwort seldom gets the chance to establish. Pulling and digging is often the most effective control method. Hand tools can be used to make the job easier such as a ‘lazy dog tool’ and a ‘rag-fork’. Gloves must be worn! This method should be done early in the summer before the flower heads mature with best results when the soil is wet. This enables the whole plant to be removed as small bits of root left in the soil can grow becoming new plants. Roots are more likely to break in dry ground potentially creating a larger problem with a halo of new plants around the removed parent plant. Cutting can be used as a method, however it is essential to cut before seed heads are mature and this must be followed with another control technique. Cutting may stimulate the growth of side shoots and vigorous growth in the following year.
Common Nettle is usually best managed through cutting by mechanical means such as a tractor-mounted cutter, strimmer or by hand, using a scythe. This method is best used where infestations of Common Nettle are small, bird nesting is not an issue, equipment and labour are available and where total control is neither desirable nor necessary. Repeated cutting combined with close mowing of the area will weaken Common Nettles and allow the grass to successfully compete over a period of years.
There are other species of thistles that are not considered problem plants, such as:
There are other Dock species that are present in grassland and are not considered problem plants in the legislation. These include:
There are other Ragwort species that are present in grassland and are not considered problem plants in the legislation. For example:
Managing or making meadows, whether in a lawn or larger site, can sometimes lead to prickly problem plants like docks or nettles. Follow our expert advice for managing problem plants.
Yellow Rattle, is the single most important plant you need when creating a wildflower meadow. Here’s everything you need to know.
Want to start a community meadow, but not sure where to begin? Read our guide to creating a flower-filled haven for your local community.
Known as nature’s meadow maker, Yellow Rattle, is the single most important plant you need when creating a wildflower meadow.
Here’s everything you need to know.
Yellow rattle, commonly known as the meadow maker, is one of the most important plants you need for a meadow. Without it, vigorous grasses can grow unchecked and smother flowers you want to encourage.
As Yellow Rattle Rhinanthus minor grows in a meadow the grass will become thinner, making room for plants like Oxeye Daisy, Knapweeds and Vetches to appear. And if you’re lucky, maybe even an orchid will pop up.
Then large bees, especially bumblebees, move in and pollinate the flowers of yellow rattle and it’s large seed pods dry and ripen. This leaves the seeds rattling around inside. Farmers used to use the sound of the rattling seeds as their cue to cut the hay – hence the name.
Yellow Rattle is a very useful starting plant when making a wildflower meadow, but it can be a little tricky to establish. Here are some top tips to get you started:
If you have very fertile soil, it might be trickier to grow Yellow Rattle. Poor and infertile soils are best and following the steps above will help reduce the fertility of your soil over time.
Your go-to guide for transforming places into flower-rich meadows.
Late summer (August-September) is the best time to sow Yellow Rattle. It will not grow successfully if sown in the spring. The seeds can be sown no later than November because they need about 4 months below 5C to germinate in the spring.
Yellow Rattle is easy to collect by hand. Simply hold a paper bag under the ripe seed pod and shake it gently with your fingers. Collecting larger quantities can easily be done using a vacuum or leaf blower.
WATCH: Plantlife’s Sarah Shuttleworth collects Yellow Rattle with a vacuum.
There are a number of reasons why Yellow Rattle may disappear from a meadow, including:
For meadows, we recommend 0.5-2.5kg per hectare/10-20g per m2 if you are collecting your own seed.
There are several possible reasons:
It’s not just humans and animals that have DNA in their cells, plants and fungi do too.
In fact, DNA barcoding can be used to identify plants, detect invasive species and help conservation work, as our Senior Ecological Advisor Sarah Shuttleworth explains.
Like all living organisms, plants and fungi have DNA (deoxyribonucleic acid) in their cells. DNA is the genetic code, which is the blueprint for genes, which gives an organism its specific characteristics. Different species will have a different DNA blueprint (with small variations within that as well) and these can help us tell species apart and see which ones are closely related.
I was recently offered a place on an exciting course to learn all about DNA barcoding and how it can help my work as a botanist.
Put simply, we can compare different DNA blueprints by comparing just a small section of the DNA sequence. This small section is referred to as the DNA barcode. There is a reference library which contains information about many species with their corresponding barcode.
In order to compare DNA barcodes of different species, the shortened sequence (region) needs to be the same region of the comparison species. However, which region you select to shorten and use for comparison is different depending on which type of organism you have. For example, all organisms within the animal kingdom are identified using the same specific DNA region, whilst all plants are identified using a different region.
The DNA region used for barcoding differs between kingdoms:
DNA barcoding relies on a region of DNA that varies significantly between different species to allow the different species to be identified.
First, we need to collect a tiny bit of plant and/or fungi samples for our study. We don’t need much, just a small amount to get the DNA. To get the DNA out, we cut really tiny pieces from the samples. Then, we put these pieces in a tube with a special liquid solution and smush them with a small tool to break the cells apart and release the DNA.
Next, we need to make lots of copies of the DNA which we do by using a special mix of certain chemicals (there are different special mixes for plants and fungi).
To check if we’ve done it right, we use a method called gel electrophoresis. This method is used to separate mixtures of DNA, RNA, or proteins to molecular size (you will see a nice clear line in the gel if it has been successful.) This helps us see if the DNA we extracted is good and whether we can send it to the lab. The lab will then send us the DNA sequence so it can be compared it to other sequences in a big database.
Using these DNA barcoding skills can help us in many ways, including identifying single species or a community of species.
It is quite a technical process but as local groups (mainly fungi recording organisations) are starting to invest in the kit, more people should be able to get involved in DNA barcoding.
I hadn’t had a chance to do anything like this since my first year at university and I was surprised about how much came flooding back to me. The course was a great opportunity to learn and refresh my skills, as well as meet other people with an interest in species identification and conservation.
After more practicing, we hope to use these skills to add to the genomic database and assist our own species recording accuracy.
In the future, perhaps Plantlife can utilise these skill sets for looking at species assemblages on our reserves or places we are hoping to maximise conservation efforts.
Volunteer biological recording group RoAM (Recorders of the Avalon Marshes) at Somerset Wetlands NNR (National Nature Reserve) organised the DNA barcoding course with funding from Natural England through the Natural Capital and Ecosystem Assessment Programme. I was offered a spot on this exciting course due to my work and contacts in a voluntary capacity with the North Somerset and Bristol Fungi Group.
Natural England: EDNA (Environmental DNA) approaches to environmental monitoring are incredibly valuable to Natural England’s work, but recognise their limitations, not least that some groups of fungi, lichen and invertebrates are poorly represented in genomic databases. By helping to train our highly skilled taxonomic recorders with DNA barcoding means better records and more effective eDNA outputs.
Thousands of people across the country have let it grow for #NoMowMay this year.
Our gardens have bloomed with wildflowers and grasses and we’ve seen our green spaces grow beautifully wild – all to give nature the boost it deserves.
Every No Mow May lawn is different and perhaps that’s what makes them so beautiful. But we are all connected by a common goal…to leave space for nature.
Thank you to everyone who has taken part in No Mow May, we hope you’ve enjoyed watching your gardens and green spaces bloom. Whether you left your whole garden to grow, kept a section short, had a go at growing a wildflower meadow or just left a space to grow wild – it all makes a difference.
We’ve absolutely loved looking through all the pictures you’ve sent in and following your #NoMowMay journeys on social media. Please keep them coming!
Since the 1930s, we’ve lost approximately 97% of flower-rich meadows and with them gone are vital food needed by pollinators like bees and butterflies.
And with 1 in 5 British wildflowers under threat, it more important than ever to change the way we manage our gardens. A healthy lawn or green space with some long grass and wildflowers benefits wildlife, tackles pollution and can even lock away carbon below ground.
There are more than 20 million gardens in the UK, so even the smallest grassy patches can add up to a significant proportion of land which, if managed properly, can deliver enormous gains for nature, communities and the climate.
Here are some of our favourite No Mow May-ers from 2024!

To help nature, you don’t have to leave your whole garden to grow wild. Keeping some areas of your lawn short can help flowers like daisies and dandelions, as well as an abundance of wildlife.
The explosion of colour No Mow May can create can be a haven for us, and for nature.
Green spaces left to grow wild have bloomed with daisies and dandelions, providing a feast for pollinators.
Even if you don’t have a garden, many parks around the country are leaving sections of green space to grow for No Mow May – just like this park in Wales.
Every year we call for people, communities and councils to get involved in #NoMowMay – and you still can this year.
Even though we’re approaching June, you can still join the movement and register your green space. This helps us to better understand how much green space across the UK is growing wild. So please sign up and help us give nature the boost it deserves in 2024 (you’ll even be added to our interactive No Mow May map!).
And the buzz doesn’t have to stop there. If you are able to, why not carry on and do Let it Bloom June.
Grassland wildlife comes in different flavours and incorporating different grass lengths into your garden can be wonderful for wildflowers and wildlife alike. Take a look at our top tips for building on the success of No Mow May.
As well as bringing back the bloom to our lawns, there are many ways you can get involved with No Mow May, even if you don’t have a garden.
If you want to create a home for wildlife in your garden, here’s a couple of nature-friendly gardening jobs to inspire you. If you create the right space, nature will come.
It’s not just wildflowers which benefit from not mowing our lawns this May. Pollinators and other wildlife bring our gardens to life!
The beautiful mountain plant, Rosy Saxifrage, has returned to the wild in Wales after becoming extinct in 1962.
This beautiful mountain plant, that once clung to the cliff edges in Eryri (Snowdonia) has successfully returned to the wild in Wales after becoming extinct in 1962.
The trial reintroduction of Rosy Saxifrage Saxifraga rosacea, led by us, marks a special moment for nature recovery. The plants, which have been maintained in cultivation, have direct lineage to the 1962 specimens.
It is now flowering at a location close to where it was last recorded in the wild – and there are plans in place to boost its numbers now the first trial has taken place.
The species was first recorded in Wales in 1796 by J.W.Griffith (Clark, 1900) and there are up to five records from the 19th century. In the 20th century, there are three records, all in Eryri.
But, it is thought that Rosy Saxifrage slipped into extinction in Wales, primarily as a result of plant enthusiasts over collecting the species, particularly in the Victorian era. Atmospheric pollution is also considered to have played a role. Rosy Saxifrage is not a great competitor with stronger growing plants, so it was impacted by the nutrient enrichment of its favoured mountain habitat.
Each and every native wild plant contributes to the diversity and health of ecosystems and putting Rosy saxifrage back where it belongs restores a lost balance.
The successful reintroduction has been led by our botanist Robbie Blackhall-Miles, Project Officer for the Tlysau Mynydd Eryri (Mountain Jewels of Eryri) conservation partnership project that aims to secure the futures of some of our rarest alpine plants and invertebrates in Wales.
The outplanting took place on land cared for by the National Trust and in future months botanists will conduct surveys to establish places where it will be best to reintroduce the species fully to the wild.

It’s not just trees that capture and store carbon – our meadows and grasslands can play an important role too.
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.
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 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.
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!
Thousands of people across the country have been letting it grow for #NoMowMay this year – and this is what it looks like!
