Review of the status of Devon Special Species

and of current priorities for action

Robert Wolton

March 2020

Report commissioned by Devon County Council on behalf of the Devon Local Nature Partnership

1. Summary

In 2017, 96 species were identified as ones for which Devon has a special responsibility for their UK survival. These are known as Devon Special Species. This report reviews their current status in the county, in terms of trends in population and range, and whether sufficient action is being taken to secure their future. It has been commissioned on behalf of Natural Devon, the Devon Local Nature Partnership. The review is based largely on the knowledge and opinions of relevant experts: some relevant information may not, however, have been captured reflecting time limitations.

For those species were an assessment could reasonably be made, 48 are currently, or have recently been, the focus of targeted conservation action. This is encouraging. Nonetheless, at least 21 species have been identified as requiring new or increased conservation effort. Of these, eight are likely to require urgent action to secure their future in Devon. They are:

1. Opegrapha subelevata, a scribble lichen

2. Goldilocks aster Aster linosyris

3. Strapwort Corrigiola litoralis

4. Freshwater pearl mussel Margaritifera margaritifera

5. Coleophora linosyridella, a case-bearing moth

6. White-clawed crayfish Austropotamobius pallipes

7. Allis shad Alosa alosa

8. European smelt Osmerus eperlanus

More species (53) are being adequately monitored than not (35), with insufficient information being available to make an assessment for the remaining eight species. 17 species have been assessed as priorities for further monitoring or survey. These are:

1. Wadeana dendrographa, a lichen

2. Toadflax-leaved St John’s-wort Hypericum linariifolium

3. Plymouth pear Pyrus cordata

4. Triangular club-rush Schoenoplectus triqueter

5. Apple lace bug Physatocheila smreczynskii

6. Actocharis readingii, a rove beetle

7. Beach comber beetle Eurynebria complanata

8. Bog hoverfly Eristalis cryptarum

9. Sphaerophoria potentillae, a totem hoverfly

10. Perkins' mining bee Andrena rosae

11. Broad-faced furrow bee Lasioglossum laticeps

12. Long-horned bee Eucera longicornis

13. Six-banded nomad bee Nomada sexfasciata

14. Infurcitinea albicomella, a tineid moth

15. Lichen running spider Philodromus margaritatus

16. Hazel dormouse Muscardinus avellanarius

17. Grey long-eared bat Plecotus austriacus

As expected, given that Devon Special Species were selected on the basis that they are threatened, more are decreasing (or likely to be decreasing) in range or abundance (20 species) than are increasing (12). Nevertheless, the good proportion (57%) of species that are believed to be either increasing (20) or stable (36) is positive news and reflects well on the considerable conservation effort being made by individuals and nature conservation organisations across the county.

3. Acknowledgements

This report is based on information provided by many natural history experts with in-depth knowledge of Devon. Most are acting in a voluntary capacity: without their willing help and passion for the natural world and its conservation, this report would not have been possible. A huge thanks to all who have contributed. They are:

Many others have helped to conserve Devon Special Species over recent years, whether by monitoring, survey, research or site management. That an unexpectedly high proportion of the species are faring well is a tribute to their involvement and action.

Devon Biodiversity Records Centre has worked hard to raised awareness of Devon Special Species with partners and the general public, and in project development, as well as maintaining the county records database.

Finally, thanks to Devon County Council for commissioning this review on behalf of the Devon Local Nature Partnership (DLNP), especially to Sarah Jennings, County Ecologist and DNLP Manager, and to Tom Whitlock.

4. Introduction

In 2017, a list of threatened or scarce species for which Devon has particular conservation responsibility at a UK level was produced. The 96 species on this list are known as ‘Devon Special Species’. The list covers fungi, plants and animals, of both land and sea. Please see the 2017 report for the context within which the short list was produced, the criteria used to select species for inclusion, and a breakdown of the 96 species by major taxonomic groups and by habitat.

Just over two years on, this report reviews the status of each of these 96 species in terms of trends in their ranges and population sizes in the county. It identifies which species are priorities for further survey or monitoring work, and, most importantly, which species are priorities for increased conservation action, to ensure their continued survival.

As with the production of the short list in the first place, this review has relied heavily on information provided by species experts, most of whom were also involved in drawing up the short list in the first place. They are acknowledged above. Additional information was taken from published sources such as the new county atlases of flora and birds.

The search for information was not exhaustive, reflecting time constraints, and without doubt some knowledge and information has not been captured. There are likely to be conservation actions being taken for some species of which both consultees and the author were unaware.

5. Key findings

17 species have been assessed as priorities for further monitoring or survey (Table 1). These species have been picked out either because they are believed to be declining, even at risk of county extinction, yet we have poor understand of their current status, or because we simply known very little about how they after faring in the county in the 21st century. A full list of species assessed as needing better monitoring is given at part 8 of Annex B.

Eight species urgently require new or increased conservation action if we are to secure their future in Devon (Table 2), as suggested by available evidence. A full list of species assessed as needing further conservation action can be found at part 14 of Annex B: there are 21 of these.

The numbers of species assessed as increasing in range or abundance in the county since 2000, or decreasing or remaining stable, are presented in Table 3. The numbers in each category are split according to whether the evidence for change is strong or weak. 12 species are, or are likely to be, increasing, 20 to be decreasing, and 36 to be stable. For 28 species insufficient information was available to make an assessment. Note that some species have been assessed on the basis of expert opinion of habitat or site status rather than actual monitoring of the species themselves. See parts 1-7 of Annex B for details of which species fall into which category/evidence class.

The numbers of species for which current levels of monitoring are either considered adequate or inadequate to detect changes in range or abundance with reasonable confidence, or to pick up new threats, are presented in Table 4. For 53 species existing levels of monitoring are probably adequate, but for 35 they are not. For eight species insufficient information was available to make an assessment either way. Of the 35 species where monitoring was assessed as inadequate, 17 are apparently in urgent need of further monitoring or survey, as listed in Table 1 and noted above. See parts 8, 9 and 10 of Annex B for details of which species fall into each category.

A breakdown of species according to whether or not they are currently either the focus of conservation action specifically targeted to benefit them, or they are likely to benefit from action currently being taken to improve their key habitats or sites, is given in Table 5. 48 species are the focus of conservation action, 36 are not. For 12 species insufficient information was available to make an assessment – further consultation with experts and the conservation and land management community is needed. See parts 11, 12 and 13 of Annex B for details of which species fall into each category. Note that a lack of targeted conservation action is not necessarily a failing – for some species no action is apparently needed at this time, as far as is known. Examples include rare species occurring in places that appear ecologically stable.

Finally, Table 6 considers the numbers of species for which available evidence suggests that further conservation action is needed to secure their future in Devon. In all, there are at least 21 species requiring new or increased conservation action. Of these eight have been picked out in Table 2 as being priorities for action, as stated above. There is, however, a rather large number of species, 42 of them, for which insufficient information was available to make an assessment as to whether further action is required or not. See parts 14, 15 and 16 of Annex B for details of which species fall into each of these categories.

Table 1. Species for which further monitoring or survey work is urgently required.


This globally rare lichen is at high risk from ash dieback disease. Most of its known sites in Devon have not been visited recently. The land managers should be aware of the lichen and advised not to fell host trees unless they pose a high risk to safety or property.

2. Toadflax-leaved St John’s-wort Hypericum linariifolium

The last review of the status of this rare plant was in the in the mid-1990s. Further survey work is required now to establish the current extent of populations.

3. Plymouth pear Pyrus cordata

In Plymouth, one of just two sites for the tree in the UK, populations have not been monitored for some years. Plans are underway to rectify this in 2020.

4. Triangular club-rush Schoenoplectus triqueter

This critically endangered plant was reintroduced to the tidal stretch of the River Tamar, the only place in the UK where it exists. However, populations do not appear to have been monitored since 2013.

5. Apple lace bug Physatocheila smreczynskii

Other than at one site, which is on the National Trust’s Killerton Estate, the current status in Devon of this nationally rare bug of lichen-covered apple trees is unknown.


Last recorded at just one site in 2017, the Devon status of this beetle, which unusually lives in the intertidal zone on sandy shores, is uncertain.

7. Beach comber beetle Eurynebria complanata

This strandline beetle has not been seen at its only remaining locality in England, Saunton Sands (backed by Braunton Burrows), since 2002. Further focussed survey is urgently required to establish whether it still exists here.

8. Bog hoverfly Eristalis cryptarum

This Critically Endangered hoverfly is now known in the UK only from a few mires on Dartmoor. Although it is known to continue to exist in low numbers at a few sites, there has been no comprehensive survey since 2008 of its known sites, or assessment of their condition.


This hoverfly is known from only three sites in the British Isles, two of which are Culm Grasslands in northern Devon. It appears to have very restricted habitat requirements and as such could be at risk from well-intended but uninformed management. Detailed surveys of its occupancy of its two Devon sites are required.

10. Perkins' mining bee Andrena rosae

The nationally rare and declining bee was last seen in Devon in 2009. It seems to have been lost from Exmoor and Dartmoor but may yet survive on the north Devon coast near Hartland. Survey work is required, to inform site management.

11. Broad-faced furrow bee Lasioglossum laticeps

This very rare bee is known in the UK only from the soft sea cliffs of East Devon and West Dorset. However, the current status of the bee in Devon is unclear: targeted survey effort is required, especially within the Axmouth to Lyme Regis National Nature Reserve.

12. Long-horned bee Eucera longicornis

Although nationally the range of this bee is expanding, in Cornwall it is declining and its status in Devon is unclear. The bee is of particular importance as the host of the Six-banded Nomad Bee, another Devon Special Species (see below).

13. Six-banded nomad bee Nomada sexfasciata

This Critically Endangered nomad bee is known only from the vicinity of Prawle Point in the British Isles. Here just a single individual was seen in 2019, and the species is at risk of extinction in Devon and hence in the British Isles. Together with its host, the Long-horned Bee, another Devon Special Species (see above), it requires considerable research and survey effort.


It is no longer certain that this moth survives at its only known British location – a single place on the coast at Torbay – following work to remove non-native invasive plants including Cotoneaster, one of the larval foodplants.

An attempt to re-find the moth is planned for 2020.

15. Lichen running spider Philodromus margaritatus

Devon is one of just two national strongholds for this rare and declining spider of lichen-covered trees. Its current range and abundance in the county are, however, at present unclear.

16. Hazel dormouse Muscardinus avellanarius

This charismatic small mammal continues to decline rapidly in abundance at a national level. Although it remains widespread in Devon, a national stronghold, trends in populations are not clear in this county. Either further analysis of existing data, available through the National Dormouse Monitoring Programme, is required, or a more comprehensive monitoring regime should be established.

17. Grey long-eared bat Plecotus austriacus

East Devon and Dorset together form the main centre of distribution for this very rare bat, a species which is thought to be declining nationally. Trends in range and abundance of this species in Devon are currently unknown.

Table 2. Species for which new or further conservation action is urgently required (beyond monitoring or survey)


At Berrynarbour, on the north Devon coast, a sheet of ivy cascading down the cliff is putting at risk a major site for this lichen.

2. Goldilocks aster Aster linosyris

At Berry Head, Torbay, carefully planned management is required to ensure the long-term survival of this flower which may not have produced seedlings for decades, and of the micromoth which is dependent on it, Coleophora linosyridella, another Devon Special Species (see below). A balanced approach of scrub control and grazing is required.

3. Strapwort Corrigiola litoralis

At Slapton Ley, its only native site in Britain, the survival of this plant remains perilous despite recent conservation action including propagation and reintroduction. The seasonally inundated, open, muddy shingle around the edge of the Lower Ley continues to be lost due to invasion by other plants including reed and willow scrub, reflecting the historic loss of cattle grazing.

4. Freshwater pearl mussel Margaritifera margaritifera

On the River Torridge, which has the only remaining population of any size in southern England, this species is not thought to have bred successfully since the 1960s – all individuals seen recently have been older than 50 years. The Freshwater Pearl Mussel Project, led by the Devon Wildlife Trust, which has included improving habitat quality and captive breeding, should be continued and bolstered.


Berry Head, Torbay, is one of only two known places for this micromoth in the British Isles. It is dependent on Goldilocks Aster, a Devon Special Species in need of urgent conservation action – see above.

6. White-clawed crayfish Austropotamobius pallipes

The River Culm population, one of just two remaining in Devon, is under severe and imminent threat of extinction from crayfish plague. The location and establishment of ark sites using wild caught and captive bred animals, needs to be achieved as a matter of urgency. The status of the crayfish at its other Devon site may be unknown.

7. Allis shad Alosa alosa

The River Tamar is now the only known spawning site in the UK for this fish. Like the European Smelt, another Devon Special Species (see below), it spends most of its life in coastal waters but moves upriver into freshwater to spawn. The River is currently considered to be in unfavourable condition for the fish, largely due to the barrier to migration presented by Gunnislake Weir. Funding is currently being sought to put a fish pass in place.

8. European smelt Osmerus eperlanus

The River Tamar is an important spawning site for this fish and indeed the river’s estuary is the only one in the UK designated a marine Special Area of Conservation for the species. Like the Allis Shad, another Devon Special Species (see above), it spends most of its life in coastal waters but moves upriver into freshwater to spawn. The River is currently considered to be in unfavourable condition for the fish, largely due to the barrier to migration presented by Gunnislake Weir. Funding is currently being sought to put a fish pass in place.

6. Conclusions

Given that a key criterion used in the selection of Devon Special Species was that they should be threatened nationally, it is not surprising that for those species where it has been possible to make an informed assessment more are decreasing in range or abundance (20 species) than are increasing (12 species). Nonetheless, it is encouraging that the just over half of the species where an assessment was possible are probably stable at present (36 species) and indeed that 12 are either certainly increasing or likely to be increasing. This reflects the high number of species on the Devon Special Species list for which conservation action is currently being taken or has at least been taken very recently – 48 species (57% of those where it was possible to make an assessment on the matter).

There are numerous examples of relevant conservation projects. To list a few:

· The Dynamic Dunescapes project at Braunton Burrows led by Plantlife and the Christie Estate. This will lead to habitat improvement for some seven Devon Special Species.

· The Freshwater Pearl Mussel Project led by the Devon Wildlife Trust.

· The north Devon coast bumblebee project led by the Bumblebee Conservation Trust.

· All the Moors and other fritillary butterfly projects led by Butterfly Conservation.

· The Culm Community Crayfish Project led by East Devon AONB.

· The conservation of the Horrid Ground Weaver spider and Hedgehog Harvestman in Plymouth led by Buglife.

· The Cirl Bunting recovery project led by the RSPB.

· The Dartmoor Moorland Birds Project led by the RSPB and Dartmoor National Park Authority.

· The Back from the Brink project which covers species such as the Narrow-Headed Ant (led by Buglife and the Devon Wildlife Trust) and Grey Long-eared Bat (led by the Bat Conservation Trust).

· The Devon Greater Horseshoe Bat Project led by the Devon Wildlife Trust.

Further projects are planned but not yet funded, such as Life on the Edge, a South Devon AONB and Buglife initiative, and work by the Environment Agency and Natural England to improve the fortunes of Allis Shad and European Smelt.

Outside of major projects a diverse range of Devon Special Species are receiving targeted conservation action. To name but a few: Heath Lobelia, Southern Damselfly, White Spot moth, European Spiny Lobster and Hazel Dormouse. This is all positive!

It is also encouraging that 60% of species for which the relevant assessment could be made are being adequately monitored at present (53 species). Voluntary groups and individuals play a major and essential role in this monitoring and their efforts are to be thoroughly commended. Examples of groups include the Devon lichenologists, Devon Moth Group, Devon Fly Group, Devon Birds and Devon Mammal Group. Their efforts are complemented by numerous volunteer surveyors working for organisations such as Butterfly Conservation, Devon Wildlife Trust and Bat Conservation Trust.

Nevertheless, we do not know enough about the status of at least 35 Devon Special Species, so cannot rest on our laurels. In particular, we know so little about the status of some species, or at least have insufficient knowledge about the fates of several that are Critically Endangered at a UK level, that 17 require urgent monitoring or survey if we are to be in a good position to take any positive conservation action that may be needed to secure their future (see table 1 for details of the species).

For a high proportion of Devon Special Species, that is 44% (42 species), available evidence on status was not strong enough to be able to say with any confidence whether further conservation action is needed or not. Some of these species are very elusive or appear intermittently or unpredictably, such as three of the four fungi, making them very difficult to monitor, while for others we know so little about their current status in the county that no judgement can reasonably be made at this time on whether they require special conservation measures or not.

Nonetheless, it is apparent that, despite all the excellent conservation action that is being taken, for at least 21 species new or further conservation action is needed, beyond that already being delivered or about to be delivered. Eight of these probably require such action as a matter of urgency (see Table 2 for details of these species).
