This autumn, help Plantlife find Britain’s most colourful and important fungi – waxcaps.
Britain is home to some of the most important waxcap grasslands in the world. However many species are becoming rare and declining; they need identifying and protecting.
#WaxcapWatch
Waxcaps are an indicator of rare, species-rich grassland. Knowing where waxcaps and other grassland fungi are thriving helps us pinpoint where fragments of ancient meadows survive, so we can protect them for the future.
Not just important for the hundreds of wildflowers they can be home to, these ancient grasslands are also crucial in the fight against climate change. Species-rich grassland can store up to a third more carbon than areas with just a few species.
You don’t need any fungi ID skills or to be a mycologist for do a waxcap survey. It’s easy for anyone in England, Scotland and Wales to take part in the Waxcap Watch – all you need is a smart phone or access to a computer!
Click through the instructions below to guide you from start to finish.
Alternatively, after you click the link above and select ‘Open in browser’, you can launch the survey in your web browser without having to download Survey123 app.
After you submit your first survey, the next time you open the Survey123 app click on the WaxcApp icon (red waxcap with Plantlife logo) and then ‘Collect’ to fill out another survey.
Visit a field, park, road verge, pasture, heathland, dune or cemetery; in fact, you can visit any grassy area which is open to the public, or for which you have the landowner’s explicit permission, between September and late November when waxcaps look their best.
They can be found growing in:
The easiest way to search an area for waxcaps is to walk in a zig-zag pattern at a slow pace, as some of the mushrooms are only a few centimetres tall!
Use the app to complete a few questions about the place you are visiting and to record which colours of waxcaps and grassland fungi you can see.
There is no restriction on the number of surveys you do – the more the better as this will help build a picture of what can be found at your site throughout the fungus season. Different fungi will come and go as the months change. Some fungi are visible only for a few days or weeks at each time.
Learn more about waxcaps, types of mushrooms known for their shiny-looking caps, and how to find them.
Take your waxcap knowledge to the next level with our training course, suitable for keen fungi finders and land owners.

You are responsible for your own health and safety; Plantlife do not accept any liability or responsibility for the wellbeing of surveyors. Similarly, they do not accept any liability or responsibility for damage to, or loss of, personal property.
We always recommend visiting sites and undertaking surveys with someone else and taking the following precautions:
– Check the forecast and make appropriate arrangements. If the weather changes you may need to rethink your plans.– Take care on uneven or slippery ground and keep to footpaths where necessary.– Take a mobile phone and let someone know where you are going and when you expect to return.– Most fungi are non-toxic; even toxic ones are safe to hold. However, always wash your hands after handling fungi.
England and Wales
Grassland fungi can be found across a variety of different sites, many of which are publicly accessible, such as playing fields, parks or cemeteries. Where there is no open access, keep to public rights of way (footpaths and bridleways). If you plan to carry out a survey on private land, please make sure you obtain the landowner’s permission to access the site.
Scotland
Make sure you follow the Scottish Outdoor Access Code when carrying out this activity.
Where possible, we would highly recommend using the Survey123 app to complete the survey. It is much more convenient to use, especially when filling in the survey outdoors. The Survey123 app allows you to view and/or edit surveys you’ve already submitted, submit surveys while offline, and save answers to avoid re-entering the same information.However, if using the app is not feasible, you can alternatively follow this link and then select ‘Open in browser’ to launch the survey in a web browser on your computer. If you choose this option, we recommend looking over the survey form first to see what information you will need to record when carrying out your survey.
You can still access and fill out the survey without mobile data but you must download the Survey123 app in order to do this.When connected to Wi-Fi or mobile data, download the Survey123 app, as well as the Waxcap Watch survey. You can then begin capturing survey information without a data connection. Upon completingthe survey, you will be given the option to ‘Save in Outbox’, please select this option (see below). In doing so, all your survey results will be stored locally on your device.
When you are able to reconnect to Wi-Fi or mobile data, you will need to submit your survey that has been saved in your Outbox. To do this, navigate to the survey summary page where you will see an ‘Outbox’folder. By clicking on this folder, you will be able to see the survey you filled out and can submit it by clicking ‘Send’ in the bottom right corner of the screen

Plantlife and NPMS staff tested 10 popular plant identifying apps out on the field and picked 3 of the best for you to take out on your next wildflower hunt.
These days it seems there is an app for everything, including finding out what creature critter or plant you are looking at. But are they useful? Are they accurate?
We tested 10 popular apps out on the field to put them through their paces, and picked 3 of our favourites. We looked at ease of use, accuracy, costs involved and what additional features they have.
If you prefer browsing the web, visit our Plants and Fungi page here to learn more about the amazing species you can find in the UK.
Our favourite app from the ones tested, this is free to download with no intrusive adverts or other costs involved.
The aim of the Flora Incognita research project is mapping plants, therefore they record and use the location of where the plants are found.
That means using this app is not only beneficial to your learning, but also makes an important contribution to biodiviersity monitoring and research.
This app combines traditional plant identification with the latest methods of AI. To identify, simply click on the plus symbol which takes you through your options.

Claiming to be ‘the botanist in your pocket’, this app uses advanced artificial intelligence and was accurate for a wide range of species, from Sea Thrift to trickier species such as Mouse-ear Hawkweed.
Advertised as £24.99 a year, you can use the app indefinitely to identify plants without paying: when you open the app you come to a pre-home screen where you click cancel.
Other benefits include the app’s ability to identify common grasses, sedges and fungi – but we recommend some caution with these due to the cryptic nature of IDing these species. Picture This also has common questions and answers for each plant, along with stories and other interesting facts such as flowering times.
iNaturalist was created with the aims of recording your observations and sharing them with the ability to crowdsource identifications. The app is free and has a range of handy features that make uploading a breeze, including an automatic location based on the photos’ GPS tag, and the ability to record other wildlife such as insects and birds.
We found the app very accurate to a plant’s genus, a group of similar species, and sometimes even down to the specific species when multiple photos are added. This makes it the perfect tool for you to take your plant ID knowledge further with a field guide.
Seek is a simpler version of iNaturalist with an easier interface for the family. We found Seek had less accuracy in the field, so if you’re looking for something more thorough, we recommend downloading iNaturalist.

Hywel Morgan
Learn from Hywel Morgan, Plantlife’s Agricultural Advisor, about how and why he made the switch to nature friendly farming on his 230-acre beef and sheep farm at the western end of the stunning Bannau Brycheiniog (Brecon Beacons National Park).
‘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.
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.
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.
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.
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.’

This summer Plantlife Cymru have worked closely with Carolyn Thomas MS, our Species Champion for Butterfly Orchids, to raise awareness of the importance of grasslands far and wide across Wales.
Species Champions are Members of the Welsh Senedd, chosen to represent threatened species found in their constituency and champion them both within the Senedd and across Wales. Carolyn Thomas MS is deeply passionate about supporting our wildlife, from nature friendly green space management to improving protections for our precious biodiversity.
This year, Carolyn was able to join us and North Wales Wildlife Trust for the big Butterfly Orchid count in our North Wales nature reserve Caeau-Tan-y-Bwlch, in June. Participating in the count meant she was able to contribute first-hand to the monitoring and understanding of a rare and beautiful species.
We counted the highest number of Greater Butterfly Orchids ever recorded at the reserve in over 40 years – some 9,456 flowering spikes of this rare plant were found within the diverse upland hay meadow near Caernarfon. Carolyn reflected on this important day in her Senedd statement on 28 June:
“Last Saturday, as the Butterfly Orchid species champion, I took part in a Butterfly Orchid count at a wildflower meadow, owned by Plantlife Cymru and managed by the North Wales Wildlife Trust. The meadow was rich in diverse species, which has created habitat in return for many animals and insects, such as butterflies, ladybirds, damselflies, crickets, spiders and tiny frogs. The place was alive and very beautiful.“
Another visit to a beautiful meadow just outside Mold in north Wales on National Meadows Day gave us the perfect opportunity to discuss some of the threats that our species-rich grasslands face. Our Species Champion was able to see first-hand how a lack of management was allowing scrub to encroach onto the valuable grassland habitat, but also to hear how the efforts of volunteers were protecting the grassland that remained.
Staff and volunteers from Plantlife Cymru and North Wales Wildlife Trust also talked about how incredibly precious fragments of species-rich grassland can too easily slip through the nets of protection and face damage from neglect, but also from development, agricultural use and inappropriate tree planting.
There was also plenty of time just to appreciate the joy of being in such a beautiful place! We were able to admire both Greater and Lesser Butterfly Orchids, as well as Common Spotted Orchids, carpets of Betony and Lady’s Bedstraw, and we were even treated to the sight of a Slow-worm. Some early Field Scabious was just coming into flower, and sheltered sunny meadow areas were alive with butterflies and moths.
In her statement to the plenary ahead of the visit which you can watch here, Carolyn emphasised to the Senedd the vital nature of thriving green spaces and advocated for the protection and restoration of our species-rich grasslands.
Thank you, Carolyn for supporting us in our mission to support grasslands and the wealth of species that rely on them!
How Plantlife is moving one of the most endangered wildflowers in Europe off the Red Data list for Great Britain.
The Fen Orchid Liparis loeselii, is one of the most endangered wildflowers in Europe, but successful conservation efforts have given hope for its survival. The orchid is only found in two areas of the UK:
We believe that the orchid could finally be removed from the Red Lists for both England and Great Britain.
After a decade of research and partnership work, the orchid has been re-discovered at former sites in the Broads, and the total population has estimated to have risen to over 15,000 plants through proper management.
The orchid has also been reintroduced to its former sites in Suffolk, and the signs are encouraging that it will become established in some of its old homes.
In South Wales, the conservation effort to restore the fragile dune habitat at Kenfig and to rediscover the plant at former dune locations.
At Kenfig numbers had dropped from a conservative 21,000 at the end of the 1980s to just 400 when conservation work began.
After almost 10 years of work, over 4000 Fen Orchids have been counted, more than double the highest number seen in the last two decades.
The orchids once grew at eight dune sites along the south Wales coast, but a lack of active management led to their disappearance. The success at Kenfig gives hope for other dune sites like Whiteford and Pembrey, the former of which the plant has recently been re-found after searching.
45% of flowering plants are at risk of extinction.

Reverse the Red
We know there are some endangered animal species in the world, but did you know some of our plants are also threatened by extinction?
The good news is saving them is possible. Here are three plants species that are endangered in Wales and the fabulous work that’s being done to bring them back from the brink of extinction.
This is our only native species of Cotoneaster in Wales, Cotoneaster cambricus, and in the 1970s it was down to as few as only 6 plants in the wild, making it international critically endangered!
It’s only found in the Great Orme IPA near Llandudno, where our vascular plants officer, Robbie, works alongside the National Trust, Conwy County Borough Council, Natural Resources Wales, PONT, and the tenant farmer, Dan Jones, to graze the land in a way that benefits the species.
This, paired with efforts to plant out young plants have been a resounding success, and we’ve gone from 6 to well over 70 plants. We are now working with research students, Dan and Treboth botanic garden to understand the impacts that changes to grazing practices have on this species, so that we can understand how best to manage for it in the future.
What we’re finding is that managing to support this species is having knock-on positive effects on other species on the Great Orme, which demonstrates how targeted species recovery work can have a cascading positive benefit beyond that species, out into the wider ecosystem.
This small, sunny Welsh plant, a member of the dandelion family, is internationally critically endangered. It makes its home on the most inaccessible mountain slopes of Eryri (Snowdonia), where it is safe from disruption.
However, due to the changing climate, even these sanctuaries are becoming inhospitable, it is both literally and figuratively out on the very edge.
Its preference for inaccessible places, makes it problematic (to say the least) to monitor. However, conservation and extreme sports aligned when Robbie, Alex Turner and Mike Raine went out on ropes to survey for this mountain treasure. Their efforts have revealed that the plant’s population has increased from 2 individuals, to 4!
While that is still terrifyingly few, it represents a doubling of the global population of this species, and gives us hope that with support, these populations can recover.
We are delighted to have received funding for Natur am Byth!, Wales’ flagship species recovery project which we are part of, along with nine other environmental charities. Robbie will be leading on the Tlysau Mynydd Eryri (Mountain Jewels of Snowdonia) to provide an invaluable lifeline to species like Snowdon Hawkweed.
Once the project begins in September we’re going to be working with the National Trust to manage the grazing of sheep and goats on the mountain, which will hopefully create more undisturbed habitat for this species to colonize.
This mountain jewel is part of a suite of species that was once widespread all across the UK and Europe, the Arctic-Alpines.
Following the last Ice Age it would have been found over a large extent of Britain, but colonisation of species from the south as temperatures have risen has saw it retreat to all but our highest mountain tops, where the annual temperatures are sufficiently cool.
This species is classed as threatened on the UK level red list, even though globally it’s been assessed as Least Concern (it can be found across the alpine landscapes of Europe). Each species is really important part of our natural heritage and to lose a species native to a country represents a significant loss, not only culturally, but ecologically too.
Rosy saxifrage is one such species that we’ve lost, it is now extinct in the wild in Wales. But efforts are underway to reintroduce it to a trial site later this year. Fantastically, the plants that will be used are of Welsh provenance, saved from a cutting taken in the 1960s, meaning that our national genetic identity for this species will be preserved and allowed to repopulate our landscape one more.
Our species are the fundamental parts of biodiversity – the more species there are in a habitat, the more diverse that habitat is. It is this diversity that allows ecosystems to function healthily and be more resilient.
This means, when we lose species to extinction, it undermines our ecosystem’s ability to adapt and respond to climate change and other existential threats. This is the primary reason why recovering species is one of our priorities at Plantlife. With partners, we plan to recover 100 plant species, and move them out of high extinction risk categories, into lower risk categories.
We are proud supporters of the global Reverse the Red campaign – a movement dedicated to spotlighting all of the work that’s being done to try and stop extinctions and prevent further species decline.
Tune in across the month to find out more about the species that we and our partners are working on to Reverse the Red and fight back against extinction.
The good news is saving them is possible. Here are three plants species that are endangered in Scotland and the work that’s being done to bring them back from the brink of extinction.
The ultimate northerner in our flora, Scottish Primrose Primula scotica grows on coastal headlands on the north coast, including Dunnet Head, the northernmost tip of mainland – but is found nowhere else in the world. Low-growing and easily overlooked, this tiny flower which only grows a few centimetres tall – calls clifftops, mosaics of heath and machair, and rocky outcrops home.
The county flower of Caithness, Scottish Primrose can only reproduce through seeds and is known to flower twice a year, once in the early spring and again in the summer. It is easily distinguished from the common primrose by its blueish-purple petals.
Scottish Primroses greatest threat is inappropriate grazing, as it declined historically to cultural intensification. However, climate change poses just as great a challenge as it is a species that is sensitive to climate extremes.
Incidentally, species that are found in such a small area will inevitably be in danger of becoming endangered. Unfortunately, long term trends show a steep decline in Scottish Primrose populations – that’s why the Species on the Edge project has identified it as one of its key species. Our North Coast team is focused on working to grow current populations, ensuring that this beautiful rarity is not lost.
Every year in late summer, in a handful of scattered locations, constellations of one of our rarest flowers blink into life across the moors. Once much more widespread, Marsh Saxifrage Saxifraga hirculus in Scotland has now retreated to only six places, all of them remote, far-flung, and one of them on Plantlife’s Munsary Peatlands nature reserve in Caithness.
Favouring damp, nutrient-poor areas with good water flow, marsh saxifrage is an attractive plant with bright yellow flowers which appear through August and into mid-September. Where it does cling on, it can flower in great profusion, with over 1000 flowering shoots at Munsary in some years making this population the largest in Scotland.
Changes in land use, such as afforestation, over-grazing and the draining of moorland, have led to major losses of this beautiful plant. Its extinction in Austria, the Czech Republic and the Netherlands, and its dramatic decline in Britain and across Europe, led to its protection under the European Union’s EC Habitats Directive.
Marsh Saxifrage can recover when conditions are right – the population at Munsary was only discovered in 2002. Plantlife has been involved in its conservation for a number of years, and it seems that this appearance was in response to a drop in grazing levels, with the plant having been hanging on undetected for many years.
Growing almost exclusively in the native Caledonian pine forests of Scotland, Twinflower has suffered as these magnificent forests have been lost. Reduced to a handful of fragments, the pine forests are a shadow of their former selves, and are isolated from each other, scattered as small islands of woodland through the Highland landscape.
This loss of the forests means the loss of the Twinflower. Its populations have become so fragmented and isolated from each other that the distances are too great for its pollinators, which it relies on to produce viable seed. As a result, the remaining populations have become vulnerable to extinctions, with none of the genetic resilience that pollination can bring.
This genetic isolation makes the remaining plants susceptible to disease and changing environmental conditions. In the long-term, if it can’t reproduce, the species will be lost from Scotland.
Plantlife is working on the Cairngorms Rare Plants and Wild Connections project with partners to restore the forests and help the Twinflower re-establish itself. To achieve this, we are undertaking translocations of genetically different patches of the flower to areas near to each other to allow pollination to occur. This is being done with the help of volunteers and in partnership with landowners across the national park.
This means, when we lose species to extinction, it undermines our ecosystem’s ability to adapt and respond to climate change and other existential threats. This is the primary reason why recovering species is one of our priorities at Plantlife. With partners, Plantlife plan to recover 100 plant species, and move them out of high extinction risk categories, into lower risk categories.
Robbie Blackhall-Miles
Robbie Blackhall-Miles shares story of how a tiny mountain plant’s name has evolved over the years, and it’s fascinating history in Wales.
Botanical plant names can tell you all kinds of things about a plant. Often, they are descriptive as in Saxifraga oppositifolia – literally, the opposite leaved rock breaker. Sometimes, they tell of the habitat in which the plant is found or its particular use as in Salvia pratensis – the cure from the meadows.
Personally, I prefer the descriptive names; the ones that guide me to where to find the plant or how to identify it. Colloquial names for plants, and those in other languages, can be equally descriptive, and tell of the things that people thought they should be used for, and why they were significant enough to warrant a name.
There are a few here in Wales that I love. Cronnell (Globeflower) just for the way it sounds, Merywen (Juniper) – because it’s so different from any of the common English names and Derig (Mountain Avens).
In our house ‘Our Derig’ has become a pet name for a plant that we visit each year. The etymology – the study of the origins of words – is wrapped up in something more than that though and in this case it comes down to its leaves rather than its flowers.
It seems surprising to me that the resemblance of its leaves to miniscule oak leaves was picked up on by the people of Wales as well as Carl Linnaeus who gave it its binomial name in his ‘Systema Naturae’ published in 1735. The name Linnaeus chose to give to Mountain Avens was Dryas octopetala.
In his book ‘Flora Lapponica’ (1737) Linnaeus wrote “I have called this plant Dryas after the dryads, the nymphs that live in oaks, since the leaf has a certain likeness to the oak leaf…. We found it, a gorgeous white flower with eight petals that quivered in the cool breeze”. The Dryads were demigods, and their lives were tied to the life of the oak tree they inhabited. In Greek mythology a tree could not be cut without first making peace with the dryad that inhabited it.
The Welsh name for the plant takes the same likeness to oak into account with the name coming from ‘dâr’ and ‘ig’; ‘Dâr’ means oak (Derwen means Oaktree) and ‘ig’ is a reduction of the Welsh ‘fachigol’ which means diminutive.
The Welsh name Derig was first published in J.E. Smith’s Flora Britannica between 1800 and 1804, and was published again by Hugh Davies in his Welsh Botanology (1813). This early publication of this name leads to the idea that it was in general use before that point and the plant was known from Wales by the local people.
In 1798 the botanist Reverend John Evans made a tour of North Wales but never managed to climb Yr Wyddfa. Despite this Evans wrote of the routes the Snowdon guides took up the mountain and the plants that could be found there. It is interesting that he lists Mountain Avens amongst these plants despite there being no evidence of it ever having been found on that mountain.
It wasn’t until 1857 that the plant collector William Williams with discovering Mountain Avens in the mountains of Eryri, high above Cwm Idwal. Later, Williams was accused of having planted the species at this site, as it wassuspected that he planted rare species to further establish his notoriety as a botanical guide. It wasn’t until 1946 that a second site for Derig was discovered by Evan Roberts in the Carneddau.
Derig is still only found at just two sites in Wales yet there are a few other sites, including on Yr Wyddfa, where the plant community with which it shares its two known homes exists.
So, what is in a name? In this case it’s a tantalising glimpse of local knowledge surrounding plants, particularly a ‘diminutive oak’ whose first discoverers may not have been eminent botanists of the time. In this case it seems likely that the people who lived and worked alongside it knew it well, certainly well enough to recognise it and give it a name of its own.
Thanks to Lizzie Wilberforce, Dewi Jones and Elinor Gwynn for helping with the research for this blog.

Sam Jones
Plantlife’s Cairngorms Project Manager Sam Jones reveals how a tiny flower in Scotland is fighting back against extinction in the UK, and what we’ve learnt about this mysterious wee plant.
I’ve been spending a lot of time reading what little information there is on One-flowered Wintergreen, Moneses uniflora, doing site visits, and chatting with other experts. I’ve been trying to figure out what has caused its sharp decline in abundance and distribution globally, and how we can help prevent it here in Scotland.
The uncomfortable answer I’ve come to is that we still don’t really know all that well. Around 10% of the Scottish population is in the Cairngorms, the rest distributed sparsely across the Highlands. In the last 50 years, I estimate that we’ve lost half of our populations, and of those remaining, only a few are stable or improving. We may soon lose all One-flowered Wintergreen in the UK without intervention.
Thousands of years ago, before significant human alteration to the landscape of Britain, perhaps One-flowered Wintergreen existed in a particular niche. It may have relied on the bare ground made by a wild boar digging for roots in the woodland, or the wood pulp made by a beaver chopping a tree, or the trampled ground under the hoof a mighty Auroch.
In the modern world humans create this niche for them more than animals, and sadly, our modern management of pine woods has favoured it less. Through research and collaboration, we will be able to manage woodlands holistically, providing a mosaic of habitat for One-flowered Wintergreen in Scottish pinewoods, as well as other rare native species.
In Autumn 2023 we translocated 109 individual One-flowered Wintergreen rosettes from two sites in to RSPB Abernethy, reinforcing a tiny relic population. This is a very early trial, as much a learning experience for future work, as it is to improve the condition of the Abernethy population.
I have been cautious to publicise this work, as, given no one has ever translocated One-flowered Wintergreen before (or even worked towards conservation of this species), I was prepared for total failure. However, the good news is, after 9 months at their new site, survival of rosettes remains above 70%. This is excellent for a plant translocation and bodes well for further Wintergreen translocations.
We hope to do more translocations to allow genetic mixing between populations and to rescue them from threatened sites. In addition to collecting plants for translocation, 12 plants went to Royal Botanic Gardens Edinburgh, where they have been working towards understanding the complex fungal interactions which One-flowered Wintergreen relies upon to survive, and in particular, to germinate.
One-flowered Wintergreen is the only member of its genus Moneses, closely related to Pyrola, a group containing the other wintergreens, such as Intermediate Wintergreen (Pyrola media). Sadly, all are rare and in decline.
True wintergreens are partial-mycoheterotrophs, which means that they have an alternative to photosynthesis for acquiring their energy to grow. They can parasitically take sugars and other minerals from fungus in woodland soils.
This ability to uptake energy from the soil as a supplement to their photosynthesis is likely part of why they are so challenging to understand and to propagate in captivity. There have also been suggestions that the presence of specific fungi is necessary for the tiny powder like seeds to germinate.
One-flowered Wintergreen does not seem to have an easily definable niche. It is very rare, only occurring at specific sites, and often isolated to an area a few tens of metres across in a large and apparently suitable woodland.
Recently, we have had some breakthroughs helping us to understand this plant better. Trials of cattle grazing in woodland have yielded rapid recovery in a One-flowered Wintergreen population. Another site was heavily trampled and disturbed in the process of Rhododendron removal, again yielding rapid recovery of Wintergreen. These plants all seem to recover on sites where bare ground, trampled wood, and organic material are present.
On forestry sites, One-flowered Wintergreen appears to grow only along forestry tracks and where the ground has been historically disturbed. A picture is starting to emerge of this species favouring periodic heavy disturbance of woodland soils.
Armed with this information we are providing advice to current land managers. We are also investigating options for a small-scale trial translocation of One-flowered Wintergreen, as much to aid in our learning of the needs of this rare flower, as to aid the genetic resilience of a small and struggling population.

Plantlife Volunteer Story
Ever wondered how biodiverse meadows are made? Plantlife Members and volunteers Andrew and Helen Martin live on a 5-acre smallholding in rural Carmarthenshire.
Here they tell us in their own words about their own ‘Meadow Story’, and how their field is now a haven for orchids and rare plants.
In recent years, the public has been alerted by the media to worry about declines in insects, especially bees. As a former bumblebee research scientist, this wasn’t news to me because the range of many bumblebee species contracted significantly in the middle of the last century. There is little doubt that big changes in UK agriculture (and therefore most of our landscape) were responsible.
To put it very simply, there aren’t as many flowers in the countryside now as there were (for over 1,000 years) So, for us, it was always an ambition to have a little bit of countryside of our own that we could manage for biodiversity, and after my getting early retirement, and Helen being made redundant, we were off like a shot to rural Wales in 2012.
Our fields had been sheep grazed for as long as anyone locally could remember, and they were still being grazed by a local sheep farmer who rents lots of small fields along the Tywi valley.
We decided to manage one of ours as a hay meadow. Research has shown that in a new meadow the plant diversity increases more quickly if you introduce Yellow Rattle, which is partly parasitic on grasses and inhibits their growth. So, in 2013 we collected Yellow Rattle seed from a neighbour’s field about a mile away and sowed it in the field. We began excluding the sheep every year from the end of March and by April 2014 the Yellow Rattle was growing well.
In mid-June 2014 we got the neighbouring farmer to cut and bale the field, but decided that it would be better in future to choose when to cut and so acquired a 1963 tractor and some small-scale haymaking implements.
I’m not particularly keen to produce a hay crop, but for floral diversity the main thing is to ensure that all the cuttings are removed from the field to reduce the soil fertility; and the easiest way to do this is to cut and bale the hay. All we produce is sold to the farmer whose sheep return after the hay cut when grass regrowth begins. I leave the hay cut as late as possible, to allow more species to drop seeds.
Each year, different species’ dominance rose and fell as the county plant recorder predicted they would. For a couple of years there was so much Yellow Rattle, but soon it settled down to more of an equilibrium, while other things rose in frequency then settled down. Eyebright appeared after a couple of years, as did Whorled Caraway (the County Flower), and Cat’s Ear.
Some plants (like Meadow Buttercup) were probably there already, but never got to flower because the sheep ate them. Broad-leaved Helleborines appeared in 2016, and in 2017, a single Southern Marsh Orchid. Common Spotted and Heath Spotted (with hybrids between them) followed, and each year the orchid numbers have increased, it was up to 50 a couple of years back and well over 100 now.
The field looks different as different plants come into flower in succession, but it even looks different on the same day in the morning and in the afternoon because the Cat’s Ear flowers close about lunchtime, so the field is much more yellow in the morning.

Plantlife has done valuable work towards achieving that aim (especially with the recent “Magnificent Meadows” campaign). County Meadows Groups also do their bit to help small landowners to get results like this field, and in the group I chair (Carmarthenshire) we’re also trying to raise the profile of species-rich grasslands generally with the UK wide “Big Meadow Search” (www.bigmeadowsearch.co.uk).
There are few people left who can remember when every farm had a hay meadow, but I hope we can succeed in bringing some back.
