What is a sand dune?

Sand dunes are wild, dynamic landscapes. They are homes for wildlife, where carpets of orchids survive alongside songbirds, butterflies and an array of endangered insects. As a society we have forgotten the mystery of sand dunes.

They are more than just sand and less well-known is their role as a sanctuary for endangered plants and animals, like the Fen Orchid and sand lizard. Sand dunes in the UK look very different today than they did even just 100 years ago.

They are now missing the open sandy features which are homes for rare and special creatures, because bare sand has been replaced with dense vegetation and scrub. This is why our work to restore dunes is so vital.

Where are sand dunes in Wales?

If you would like to visit a sand dune, why not visit one of the sites we have protected?

  • Cymyran, Tywyn Trewan, Tywyn Llyn and Tywyn Fferam on Anglesey
  • Morfa Bychan in Gwynedd
  • Pembrey in Camarthenshire
  • Broughton, Oxwich and Penmaen burrows on Gower
  • Crymlyn and Baglan Burrows in Swansea

Dynamic Dunescapes also collaborated closely with Plantlife project Green Links Bridgend at Kenfig National Nature Reserve.

In addition to our work in Wales we have undertaken conservation management work in Braunton Burrows – Devon, working closely with National Trust, Christie Estates and the MOD.

What are the problems that dunes face?

Our coastal sand dunes are under threat. In fact, they are listed as one of the most at risk habitats in Europe for biodiversity loss.  

Since 1900, the UK’s sand dunes have declined by a third, and almost two-thirds in Wales.

One of the key problems is that many dunes are becoming more densely covered by vegetation and scrub and there is less bare open sand.

A lack of bare mobile sand is having negative impacts on many rare dune-specialised species that need areas of open sand to thrive. Healthy sand dunes need to move and be dynamic.

Helping sand dunes in Wales

Our work with Dynamic Dunescapes was a partnership funded by the National Lottery Heritage Fund and the European LIFE fund and:

  • Worked across 7,000 hectares of coastal sand dunes
  • Restored 22 sand dune sites across England
  • Restored 11 sites in Wales

Plantlife’s work with local communities to explore and learn about dunes in both Wales and Devon with Dynamic Dunescapes ran from 2020-2023.

We have also:

  • Supported the restoration of sand dunes by raising awareness of pioneering conservation action. We have provided training for young people and volunteers to contribute to sand dune restoration.
  • Raised awareness that healthy dunes need moving sand. Previously, sand dune management favoured stabilisation of dunes and we now know that sand dunes need to be dynamic.
  • Encouraged more people to explore, enjoy, and help protect the dunes through. Our work delivered a programme of innovative public engagement and citizen science events and activities from guided walks to Tai chi and musical workshops.
  • Developed skills to manage dunes better, both now and in the future through in person and online training and workshops, supporting collaboration and increasing accessibility for all to dune landscapes.

Natur am Byth! 

Many plants are special to Wales. Some of them are vulnerable and could even become extinct. It is these gems which Plantlife Cymru is working to save as part of the Natur am Byth! flagship project. This larger project unites nine environmental charities (of which Plantlife Cymru is one) with Natural Resources Wales (NRW) to deliver the country’s largest natural heritage and outreach programme to save species from extinction and reconnect people to nature. We are running two projects within the Natur am Byth project.

A team effort

In the Tlysau Mynydd Eryri project Robbie Blackhall-Miles is working with volunteers, mountain guides, local plant nurseries, land managers and botanical experts. Together they are painstakingly turning around the fortunes of these rare mountain species and setting them on the road to recovery. Along the way they are celebrating these beautiful mountain jewels and the landscapes they live in.

 

Snowdon Hawkweed

The challenges

The selected species are rare because they have, and continue to, face many challenges. Tourists in the Victorian era indulged in the fashion of collecting ferns and montane plants which reduced their numbers substantially. More recently farming practice and the way the land is used has changed out of all recognition. Today air-borne pollution, in particular nitrogen, together with climate change are making life very difficult for these clean air and cold loving plants.

The Welsh Marches/Gororau Cymru project

This project is saving very rare lichens and bryophytes living on veteran trees and dry rocky outcrops and hilltops in an area stretching from near Presteigne, Radnorshire to Gregynog near Newtown. Project officer Ellie Baggett is working to revive populations of 15 species which include some of our rarest lichens, mosses and 3 insect species.

Working with farmers

In the Welsh Marches Ellie Baggett is working with farmers and local communities to develop and put into action various practical techniques. These include clearing scrub – bushes, bracken and rank grass – so that the light loving lichens can thrive. She is also encouraging farmers to care for their veteran trees so that the lichen and moss which depend on them survive. By planting trees in the right places, Ellie hopes in years to come they will become veteran trees and provide habitats for these lichens.

The challenges

Several factors mean the selected rare lichen, moss and insect species are in danger of extinction. Some of them are actually adapted to the climate of the Mediterranean, and are near the northern limit of their global range in Wales. In some places there’s too much growth from adjacent vegetation which stops sunlight from reaching the specific lichen or moss. Elsewhere it is the veteran trees which provide the lichen or moss species with homes, which are themselves at risk of falling in storms. Another threat comes from the air, since many of the lichen species are sensitive to nitrogen pollution.

Extinct montane plant reintroduced to Wales  

Through the Tlysau Mynydd Eryri partnership project, the beautiful Rosy Saxifrage has been reintroduced to Wales, more than six decades after becoming extinct.

The Arctic alpine plant was last seen on cliff edges in the Eryri (Snowdonia) region in 1962. Now plants that have direct lineage to these specimens are blooming once again, close to where they were last recorded.

Our work is just one part of the wider Natur am Byth! programme. The 67 target species were chosen as a result of culmination of a major piece of work to establish  those that are facing the greatest threat of extinction, and are of particular importance to Wales. This was informed by the Environment (Wales) Act section 7 list, and through consultation with natural heritage experts across Wales and the UK.

Natur am Byth! Project Overview

Learning About Our Mountain Environment

Tlysau Mynydd Eryri will also collect data about some of our scarcest species to inform habitat restoration at scale.

Did you know that on the high peaks of Yr Wyddfa (Snowdon) and on the Glyderau there grows a forest that is little more than a foot high? A forest of Juniper nestled among the rocks in the crags and crevices.

A recent study undertaken in conjunction with Tlysau Mynydd Eryri and Bangor University used the fragmented records of trees that still exist on Eryri’s high peaks, historic literature, and evidence from peat cores, to piece together what the composition of this woodland may have been in Wales.

What the study found was a complex mosaic woodland made of:

Downy birch Betula pubescens, Alder Alnus glutinosa, Hazel Corylus avellana, Goat Willow Salix caprea, Grey Willow Salix cinerea, Rusty Willow Salix cinerea subsp. oleifolia, Creeping Willow Salix repens, Eared Willow Salix aurita, Aspen Populus tremula, Dwarf Willow Salix herbacea, Juniper Juniperus communis subsp. nana, Mountain Avens Dryas octopetala, Sweet Briar Rosa rubiginosa, Burnet Rose Rosa spinosissima, and Wild Raspberry Rubus idaeus.  

The trees of Eryri are still under recorded and the records of trees in the high mountains are limited. Alpine Juniper Juniperus communis subsp. nana is the most recorded tree in the uplands of Wales due to some targeted survey work that took place in the 1990s. Discover more about these miniature forests in a blog by Robbie Blackhall-Miles here.

Our Work in Wales

Wales is crammed with a multitude of vibrant habitats full of wild plants and fungi. Sadly, many of these are becoming endangered. Plantlife Cymru has a growing team of knowledgeable and dedicated staff working to safeguard them.

What’s new in Plantlife’s agricultural work

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

Challenges faced by Permanent Grasslands in Wales 

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

Benefits of permanent grasslands 

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

Plantlife’s work in permanent grasslands in Wales

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

Working with local farmers around Cae Blaen-dyffryn nature reserve 

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

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

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

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