The Rare Lichen that Travelled from Cornwall to Norfolk

An incredible story of returning one of England’s rarest lichens to its historic home – more than 350 miles away.

Let’s learn how expert Dave Lamacraft translocated the lichen across the country.

 

Dave Lamacraft translocating Scrambled Egg Lichen in Norfolk

The Scrambled Egg Lichen, a rare and endangered lichen, has been reintroduced to its historic home in East Anglia.

This yellow lichen with a white fungus on top really does look like an egg. But before you start imagining carrying it in a frying pan, let’s follow the amazing journey of transporting this lichen 350 miles.

Translocating Scrambled Egg Lichen

Taking a Lichen from Cornwall to Norfolk

The Breckland, in the east of England, has suffered more than other places with habitat loss. One of the casualties is the Scrambled Egg Lichen. It became extinct in the Breckland due to habitat loss resulting from changes in farming practices, an increase in tree cover and a loss of rabbits. The Scrambled Egg Lichen is 1 of 3 specialist lichens lost from the region, where they were once common, along with the Starry Breck and Scaly Breck Lichen.

Fortunately, we have found a way to reintroduce it back into the Breckland. Our Lichen and Bryophyte Senior Specialist Dave Lamacraft collected small patches of the lichen from Penhale in Cornwall and transported it using a process called translocation.

Scrambled Egg Lichen

What is the Scrambled Egg Lichen?

The rare Scrambled Egg Lichen Fulgensia fulgens is not just striking, but also a crucial part of the biological soil crust community which stabilises soils and facilitates the growth of other plants. It also hosts a globally rare fungus Lichenochora epifulgens which is even rarer than the Scrambled Egg lichen itself.

The UK is home to globally significant populations of rare lichen species, some of which are found nowhere else on earth. However, lichens face increasing threats from habitat loss, climate change and air pollution. Projects such as this are vital and will help us to reverse these declines.

What is Translocation?

Translocation is a process used in conservation which involves moving an organism to a new location, where it will hopefully survive and thrive. To translocate the Scrambled Egg Lichen, small patches of the lichen were carefully removed and reattached using a combination of water and bookbinding glue.

Some 200 small pieces of the lichen – about the size of a 20p piece – were removed from Cornwall and 160 transplanted into the Breckland chalky landscape. The site in Cornwall is managed by Cornwall Wildlife Trust.

About 160 lichens were translocated to a small area of about 100m at a site managed by Norfolk Wildlife Trust.

Did it work?

Measuring long term success of this translocation will take a few years, but it is hoped that if successful, the lichen will show evidence of growing after one year and spread naturally afterwards.

None of this work would have been possible without the support from Cornwall Wildlife Trust and Norfolk Wildlife Trust, with funding from Natural England as part of the Species Recovery Programme.

Hazel Gloves Fungus’ common name comes from the finger-like projections of the stromata, cushion-like plate of solid mycelium. Found on Hazel trees in Britain, it is actually parasitic on the Glue Crust fungus Hymenochaete corrugate, and not the Hazel tree itself.

It was incredibly exciting to find Hazel Glove fungus. I knew about its importance as a rainforest indicator species and also its rarity status. I had seen many photos of it and so when I turned to take a second look at something I saw in the corner of my eye, I knew at once what it was.

I couldn’t share my unbridled joy at my discovery with anyone else in that moment, unless you include telling the singing Dipper I had just spotted or indeed talking to myself about it as I walked back along the trail. However, I was able to capture that moment on camera to relive again.

What does finding Hazel Gloves Fungus tell us?

Hazel Glove fungus is an indicator of good air quality and temperate rainforest conditions, making it a flagship species for this threatened habitat. Temperate rainforests are found in areas that are influenced by the sea, with high rainfall and humidity and damp climate.

They are home to some intriguing and sometimes rare bryophytes, plants and fungi. Plantlife are working in many ways to protect and restore this globally threatened habitat. 

Fungi need you to find them!

I have since sent in my record to the county fungi recorder with a 10 figure grid reference, only to discover that this species has not been officially recorded in that area before, which only heightened my sense of achievement.

Recording fungi and sending your finds to local wildlife recorders creates a more accurate picture of the wild and wonderful world around us – and helps people like us know where to target conservation efforts.

It’s estimated that more than 90% of fungi are unknown to science, and only 0.4% of the fungi we know about have enough data to be assessed for global conservation status – letting us know if they’re critically endangered or not.

“Lichens are cool because they are everywhere. Once you notice them, you realise they are crazy, weird, colourful and interesting.”

Rob Hodgson started his lichen journey in lockdown as a complete beginner. Walking around Bristol one day, a lichen peaked his interest and from then on he was gripped by these secret miniature forests.

As an illustrator, Rob has created dynamic and lifelike lichen characters to help more people starting out.

We went to chat to Rob and join him on a lichen hunt.

What’s it like as a lichen beginner?

“It was kind of my lockdown project and I just got interested one day, like what is this crazy thing. When I first started looking at lichens, you go online and there’s a million Latin names and I was just like, no this isn’t for me – I’m not a lichen expert. But once you learn the common names and you start to spot different ones, it gets easier. You don’t have to go anywhere far away, you can see these things just on the street. There’s one called chewing Chewing Gum lichen that you can see everywhere once you tune into it, just on the pavement.

Where are all these lichens?

“You do definitely notice if you go to the countryside, it’s like a lichen explosion. But I live in the centre of Bristol pretty much and there’s still lichens everywhere. On my doorstep, you see them on the pavements, you see them on walls and in my local parks there’s loads of lichens.

It’s a really good time of year to go lichen hunting [autumn/winter] and you don’t need any stuff. You can just go and as soon as you get out of the house you are on a lichen hunt – that’s as easy as it is. You just need to look on the floor, look in the tress and you’re good to go.

Let’s meet the lichen characters…

How did you make the lichen characters?

“The way I work things out sometimes is through my work. When I was looking at lichens, I thought how can I make this more interesting than all of these super technical, botanical drawings. I drew one, and then once you notice one, you notice another, and then all of sudden I had drawn 20 different lichens.

There was a lot of back and forth between going out and looking at lichens and going back and modifying them.

That was where I was coming from, trying to make them fun and accessible.”

 

Rob has made beautifully designed lichen characters including dust lichen, shield lichen and oak moss. Follow him on social media here.

Characterised by the presence of unique lichens, bryophytes, mosses, and liverworts, rainforest habitats are highly fragmented and face threats from invasive non-native species, such as Rhododendron ponticum, alongside ash dieback, inappropriate grazing, and air pollution. 

How governments can protect and restore this internationally-rare habitat

Temperate rainforests have some of the highest diversity and abundance of wild plants and fungi in Britain, with many sites qualifying as Important Plant Areas.

Protecting and restoring this ecosystem would speed up progress in meeting national and global targets to address the nature and climate emergencies, including the 2030 Global Biodiversity Framework. Investment in rainforest restoration would also build on past and present conservation actions, and help to build a green economy through employment, skills training and tourism. 

 

The future of Britain’s temperate rainforest and its unique species depends on targeted action by the Scottish, UK and Welsh Governments to:    

1. Establish national rainforest funds from both public and private sources to support long-term landscape-scale projects and other practical action.

a) The Alliance for Scotland’s Rainforest has identified the cost of restoring the temperate rainforest zone in Scotland to be £500 million.   

2. Increase protection of remaining rainforest sites and species through national strategy, policy, and legislation.  

3. Provide advice and support for land managers to enhance and restore rainforest on their land.  

4. Take urgent action to tackle key threats to rainforest including air pollution, invasive non-native species (INNS), and deer management.

a) More than 94% of the UK’s woodland is impacted by excess nitrogen deposited through air pollution and rainfall. Lichens are essential species in temperate rainforests, but they need clean air to thrive. Lichens provide food, shelter, and microhabitats for invertebrates, in addition to carbon cycling and water retention.  

b) Invasive non-native species, like Rhododendron ponticum and ash dieback currently have the potential to wipe out much of the species diversity in Britain’s temperate rainforests. Funding projects that address this, in addition to making powers of enforcement more widely known and used where necessary, give rainforests to chance to thrive.  

c) Deer are a natural part of thriving temperate rainforest areas; however, at their current population density, particularly within Scotland, their grazing prevents essential tree species from growing and this leads to a decrease in long-term regeneration of woodland areas.

Saving Species in Devon and Cornwall’s Rainforests

Saving Species in Devon and Cornwall’s Rainforests

Our wild and wet woodlands and the species that live within them are facing severe threats which Plantlife will be tackling through the Species Recovery Project.

Thriving in areas where there is a high annual rainfall with relatively constant temperatures, our temperate rainforests are full of wonder and mossy goodness, capturing imaginations and lifting spirits of visitors.

However, they are more than just woodlands; it’s a mosaic of trees, open glades, crags, ravines, rocks and gorges. With surfaces absolutely bursting with liches, mosses, liverworts and a variety of fungi; they support a vast array of insects, birds and other wildlife, absorb carbon and slow the flow of floodwaters.

What is damaging temperate rainforests in the UK?

Nitrogen gases in air pollution have the potential to destroy these beautiful places. This pollution can take the form of ammonia emissions from farm manures and fertilisers, or nitrogen oxide emissions from fossil fuels.

Even rainforest areas far from the source of pollution, such as the northwest coast of Scotland, are affected by this threat as it can travel long distances in the atmosphere.  

UK Nitrogen depositions map

In fact, data shows that most areas of temperate rainforest in Britain have exceeded what is known as critical load. Critical load refers to the maximum amount of pollutants that something (either a person or habitat) can be exposed to before significant harmful impacts start to occur.

This map shows how the temperate rainforest zone (the area in which we would expect to see temperate rainforest sites) has been impacted by this overabundance of nitrogen from ongoing air pollution. Almost all of the rainforest in England and Wales – and almost half in Scotland – has exceeded the critical load. In total, 66% of the zone has exceeded critical load, and in many areas of England and Wales the overabundance of nitrogen goes way beyond this threshold.

Impacts of nitrogen pollution will soon be evident as trees within the rainforest will temporarily show increased growth from extra nitrogen.

However, in the long term, any growth will soon stagnate as the earth becomes saturated with excess nitrogen (more than 94% of woodlands are affected UK wide!). Higher nitrogen levels mean trees will often suffer from discoloration and increased vulnerability to drought, frost, and disease like acute oak decline.

Woodland fungi are no exception to impacts of air pollution, as many are closely associated with tree roots and health.

Their loss will result in a further decline of tree species, leading to increasing carbon emissions and further contributing to the ongoing climate crisis. 

How does air pollution affect our wild plants?

A change in flora is sure to follow an increase in air pollution as tougher nitrogen-tolerant plants, such as nettles and brambles, will outcompete the more sensitive and specialist species within the rainforest. This has a cascading effect on other wildlife which rely on certain wild plants for food, shelter, and reproduction.  

Losing species which make up a significant part of the rainforest ground cover, such as mosses and liverworts like Greater Whipwort, reduces the ecosystem’s ability to retain water. This makes the whole area more vulnerable to droughts and floods.   

Facing the loss of lichens

As an essential part of temperate rainforests, many lichens are incredibly sensitive to changes in air quality and require low levels of air pollution to thrive. These lichens provide food, shelter and microhabitats for invertebrates, in addition to contributing to carbon cycling and water retention.

Some rare lichen species are only found in rainforest areas and are being pushed to the brink of extinction. Without lichens, our temperate rainforests would struggle even more to survive.

Tree Lungwort Lobaria spp in particular is an amazing indicator species, as its presence signals that the forest is healthy and functioning as it should. This is because it is a slow growing species that is even more sensitive to air pollution than most other lichens.

Tree Lungwort often can become outcompeted and swamped in nitrogen-tolerant algae, knocking the ecosystem out of balance. When we see populations of lungwort recovering, we know that our air quality is improving and with that, the rainforest. 

How can I help protect temperate rainforest for the future?

Hope is not lost! For one, you are reading this and arming yourself with information to pass onto your family and friends. When you take action on air pollution, you’re benefiting wildlife as well as people’s health – making it doubly important!

We are working hard to combat air pollution in parliament and beyond.

Want to take it a step further?

Join us at the Restore Nature Now march in London on 22nd June, to demand that future leaders prioritise nature and biodiversity. We need immediate political action to bring endangered plants and fungi back from the brink of extinction and restore species-rich habitats, like our temperate rainforest.
