The Nottinghamshire Glow Worm Survey
...
Towards the end of 2020, I came close to the point of ending the Nottinghamshire Glow Worm Survey after some nine years. While the idea of a county wide Glow Worm survey was initially well received, actually encouraging people to become engaged with the survey proved infuriatingly difficult and it still does.
...

  Even those managing various nature reserves around the county, never contributed and they are the people claiming to be interested in the wildlife their reserves hold. In the end it came down to a few sterling members of the public, who regularly went out after dark to survey as many sites as was possible during the 'glowing season'.

Each Spring and Summer, this small band of volunteers, went out and  surveyed local sites for Glow Worms and the results of the survey since 2012, are produced further down this page. Glow Worm records can be sent directly, by using the online form and any records (both positive and negative) will appear on this page.
The Glow Worm in national decline

The Glow Worm (Lampyris noctiluca) is one of our most fascinating and endearing insects. Well known for its ability to produce light, the Glow Worm holds a unique place within UK fauna. The female Glow Worm's bioluminescent glow has formed the basis of fairy tales and folk lore over countless centuries and has charmed both children and adults througho1ut history.

Although still regarded by many authorities as being both nationally and locally common, this delightful beetle appears to be in a serious decline. Habitat loss through urbanisation and industrial development and the use of pesticides and herbicides through modern farming practices, have all contributed towards the Glow Worm's decline.

Today, we know little more about their current UK range, than Victorian naturalists did over 100 years ago. But has the Glow Worm actually declined in Nottinghamshire? Certainly there is a lack of modern records from many of its known sites, but is this through a genuine decline, or just a lack of recording?

Glow Worm distribution in Nottinghamshire

Back in 2008, our knowledge of the Glow Worm's Nottinghamshire distribution, still relied on what we thought, rather than what we actually knew. There was a total lack of modern records, even from many of it's reported sites and it was obvious that no one was actively recording Glow Worms. At the time, the coleoptera recorder for Nottinghamshire was of the opinion that Glow Worms were quite widespread throughout the county, yet the first Glow Worm distribution map we produced, instantly disputed that claim and a few of us voiced our concerns.

...
The lack of historical records or even reported sites, suggested that the Glow Worm had never actually been widespread in Nottinghamshire, but rather had always been mostly confined to the dry, sandy soils of the Sherwood Forest area and with few records (or claims of records) from other parts of the county.

It's interesting to note that most of the Nottinghamshire sites listed on the UK Glow Worm Survey's website, no longer seem to hold Glow Worms, which has been proved over the last few years by the Nottinghamshire Glow Worm Survey.

Sometimes though, proving a decline is difficult and can only ever be proved by a large amount of effort. Volunteer surveying has proved without any doubt, that the Glow Worm has indeed declined. This decline continues, even in the beetle's stronghold of the Sherwood Forest and Clumber Park areas, where it suffers from the effects of commercial forestry operations. More on this is available to read on the historical records link further down this page.

The Nottinghamshire Glow Worm Survey

In 2012, ourselves and a small group of dedicated Glow Worm enthusiasts, set out to map the Glow Worm's distribution across Nottinghamshire, in a determined effort to secure enough data to help confirm the Glow Worm's decline. Our first task was to gather and collate all available records and sites, some dating back over 100 years.

Mapping produced some unexpected results, showing that the Glow Worm's distribution was much more restricted than was previously thought. There was an almost complete absence of records from the Trent Valley, where they perhaps might have been expected. Our mapping showed that Glow Worms are largely confined to those areas of Nottinghamshire which lie on Sherwood Sandstone. This includes areas such as Clumber Park, Sherwood Forest and Sherwood Pines and it is possible that new Glow Worm sites still await discovery somewhere.

Why survey?

It is surprising how little we actually know about the distribution of many of our insects. So by surveying one of the most easily identified species, we have the chance to accurately map the Glow Worm in the county for the very first time. And since 2012, this is exactly what we have been able to do.

Site access permissions

As a general rule, you will not require any access permissions if surveying for Glow Worms along designated public footpaths or bridleways. If wanting to survey for Glow Worms on any private site, please check and arrange access permissions with the landowner before your visit.

Disclaimer:- The NGWS is not responsible for matters regarding personal safety, vehicles left unattended at remote sites, or any form of tresspass on private sites, whilst conducting any Glow Worm surveys.

  How to survey for Glow Worms

No specialist equipment is needed and the whole family can take part. Glow Worms traditionally prefer grassy habitats, but disused railway lines, forest rides and roadside verges on well drained soils, are all ideal sites to look for them. Surveying for Glow Worms is easy, but here are some simple pointers to help.

  • Surveys should be carried out at night, from about 10:30pm onwards in mid-June (depending on cloud cover) and without the use of torchlight. Your eyes will fully adapt to the dark after about 20 minutes.
  • Females will usually find a prominent stone or leaf, from which to attract a male, but can sometimes stay low to the ground. Walk in suitable habitat as soon as it becomes dark enough to see stars and simply look for the female's green bioluminescent glow.
  • A temperature of around 8ēC and a clear sky will mean few Glow Worms will bother lighting up, especially if there is a bright Moon. Surveying is ideally undertaken when the weather is cloudy, as the temperature will be higher than on a clear night. Higher numbers are often reported on damp, rainy nights.

Results

All results are needed. Negative results are as important as positive results, in helping us to map the Glow Worm's distribution across the county. Knowing more about the Glow Worm's present distribution, would also give us an idea of how we can help site owners to manage their sites more sympathetically to conserve them.

Publication and use of results

At the end of the Nottinghamshire Glow Worm Survey, all site owners will be contacted and informed of the presence of any Glow Worm colonies found on their land. All Glow Worm records will be reported to the Nottinghamshire Biological and Geological Records Centre at Wollaton Hall. All survey sites and grid references producing either positive or negative results, will be published on this website. Sites on private land will be listed as private and with no public access. Only four figure grid references will be used for such records.

How to submit your Glow Worm records/sightings to the NGWS

The quickest and easiest way to contribute your records to the Nottinghamshire Glow Worm Survey, is by completing the simple online survey form on the right. The form can also be used to send in any old Glow Worm records you may have. Old records are important in helping to determine an accurate picture of Glow Worm distribution and how it may have changed over time.

It is just as useful if we know where Glow Worms are not found, so please remember that negative results from a site, are equally as important as positive results to the survey and will help in our mapping of the Glow Worm's distribution at the end of the survey.

Nottinghamshire Glow Worm records 2022

 The season of larval surveys ended on May 13th, with the first survey for female Glow Worms commencing with surveys on May 10th and May 15th. The first female was recorded on May 17th at the bottom of Section D. This is an early date, in fact the second earliest ever female Glow Worm recorded at Clipstone Old Quarter. The latest count is of eight on June 2nd. Scroll down for the recorded glowing dates of all females on site.

Overall, this has been a hugely disappointing season, yet not really surprising, with a huge decrease in the number of Glow Worms recorded from Clipstone Old Quarter. There remain stretches of some survey sections free of Glow Worms and so far (June 19th) the grass strip sections of A,B,C and D have showed an enormous drop in numbers since 2008, but particularly within the last few years. Just 18 females have appeared in Section D so far in 2022, which has always been the most prolific section for Glow Worms here annually and a mere total of just six females have been recorded from Sections A, B and C this year combined!

As someone who has walked and surveyed this site most evenings and nights surveying Glow Worms since 2008, you can imagine how I feel to have to be recording and writing about such counts. The years of hundreds of Glow Worms at Clipstone Old Quarter, now seem a lifetime ago.

Larval survey data 2022

Early larvae were recorded on March 10th (14mm) and March 12th (20mm) and following an apparent reduction in Glow Worm numbers along the grass strip survey sections of A, B, C and D over recent years, it will be interesting to see what the subsequent larvae and female numbers will be during Spring and Summer 2022.

Larval survey data, counts and a high mortality rate - a summary of Spring 2021's larval surveys

Data gained from larval surveys during March, April and May each year, has showed a decrease in the average length of Glow Worm larva at Clipstone Old Quarter over that time. The data for March 2021 showed in Figure 01 further below, was obtained from 15 late afternoon or early evening surveys. But unfortunately, the usefulness of the data for March was rendered relatively useless by unsuitable weather conditions which followed in April.
...
  April 2021 ended up being the driest on record and although daytime temperatures were pleasantly warm on most days, the temperature dropped before late evening and made larval surveys pointless in the cold conditions. May ended up in a similar fashion, with the weather becoming very wet and cool throughout the month, halting the early progress of leaf opening on the trees, meaning very few evenings were suitable enough for surveying.

It all means that apart from the week March 22nd-31st, there has not been enough data to allow any comparitive size analysis this year, with a total of just 44 larvae meaning Spring 2021 was a poor one in terms of size data. On the whole, the overwhelming feeling the surveys gave, was the impression that the number of larvae was down on most previous years, but this was just my 'gut feeling' rather than anything which could be stated as fact.

But of the total number of larva found in Spring 2021, there has been an unusually high mortality rate. To date (May 31st) some 10/44 larvae had been killed by the increase in footfall and cycles through Sections A,B,C and D. That equates to almost a quarter of larvae found and in most years ten dead larvae would more than equate the combined total for a complete Spring period out of around 100 larvae.
...
While the effects of lockdowns as a result of Covid-19 led to a greater increase in public using the site, the blame really has to be laid firmly at the door of the site owners/managers etc, who's non commitment to Clipstone Old Quarter as part of the Birklands West and Ollerton Corner SSSI, has mean that the Sustrans path is (for most of its length here) now 30-50% the width it was originally. A narrow path meant that public use was concentrated to the centre and unfortunately Glow Worm larvae took a heavy toll. However, the Sherwood Forest Trust seem to be making moves to get together all those parties involved with managing the site and restore it to how it was a decade or so ago.

Spring 2020 - larval survey results and data

I wasn't expecting to do any larval surveying this year, but when a couple of daytime walks through Clipstone Old Quarter unexpectedly produced early active larvae, I have so far (March 24th) attempted to continue the regular routine of late afternoon/early evening larval surveys of sections A, B, C and D, which Dilys and myself did pretty much annually between 2009 and 2017. However, with the current restrictions on movement imposed by the Covid-19 pandemic, any continuous surveying is unlikely this year.

There are three tables below which I've added this past few weeks, showing the larval sizes per months of March and April. Fig 03 shows how the average size of Glow Worm larvae at Clipstone Old Quarter in Spring, has decreased since 2009. Work continues.

Survey reports and accounts

Edited survey accounts kindly sent to us and originally written by Martin Dale.

Sunday May 27th 2018 - Martin Dale .. I teamed up with Ludwik Michalek again this year and accompanied by Anna Kulpa, we set out for an early survey of the southern end of Clipstone Forest (Sherwood Pines) alongside Rainworth Water. We arrived early on a pleasantly mild evening and whilst still light, decided to walk into the forest, west along a disused mineral line from Bilsthorpe that conveniently took us back over the A614 into the woods. As the light faded we descended into a deep cutting and took a well worn mountain bike track up the bank to head for the main east-west ride where Glow Worms had been recorded in 2013 by Andy Lowe.

None found there so we peeled off down a narrow overgrown path through the trees to get down to the river bank. Within no more than 30 yards, there was our first Glow Worm of the year. After taking a quick peek at the river (audible in spate with the recent rain) we headed into an adjacent clearing and placed two lures down, before heading further in over a low sward of grass and light scrub. Just a few metres on and our second female found, followed by more and more. Great team work paid off as we fanned out to scour the transect for all we could find. Much to our surprise, a total of 25 females - three already with males. Several larval glows were noted on our way round with one peculiar bright and rapidly moving glow under foliage fading and disappearing left us all perplexed as to what it could have been.

....
Returning to the point where we came in, we found that no males had been attracted to our lures. We also noted that barring the first female in undergrowth on the path, all other females were located within the clearing. 

So a new location for Glow Worms centred at SK616601 (see accompanying map of the area) and in an area of Clipstone Forest where none had been recorded before.

A great night had by all and for me, particularly rewarding to be able to report my first Glow Worms to the Nottinghamshire Glow Worm Survey in some seven years of 'none-found' reports! At last, and a big surprise to us to find so many at this location so early in the glowing season. A site I will visiting regularly from now on.

Thursday June 7th 2018 - Martin Dale .. I teamed up with Ludwik Michalek and Phil Parry for a second visit to the Black Hill area of Clipstone Forest. The intention was to quickly check the transect we found 24 females in on the 27th May and then to look at other areas east and west along the line of Rainworth Water. Our route would initially be along the northern side of Rainworth Water, before crossing over the river to the south side, to survey any similar habitat up to the riverbank and around Damside Covert.

 
....
The weather was cool on the night, with a clear sky interspersed with cloud and light showers of rain throughout the evening. Phil and myself surveyed areas around SK622606 on our way to meet up with Ludwik but no glow worms were found. However, Ludwik had found a single female at a new location of SK620603.

Moving on to the transect previously surveyed on May 27th, just four females were found in broadly the same area. Progress was slow due to surprisingly long grass and the Bracken having grown up in the intervening days since, and now wet with the fresh precipitation. We then headed south to cross river at what was presumed from the map to be a bridge, but turned out to be a ford, so time to get our feet wet as well!

Now on the south side of Rainworth Water we surveyed east and west along 2 open transects parallel with the river. The habitat appeared to be quite different, with high grasses and boggy areas that didn't look too favourable. No glow worms were found here and it was becoming clear that the wet and cool conditions and the late hour (now after midnight) suggested that our chances of finding any were diminishing. Maybe one to do again in better weather perhaps but the habitat was less attractive that found north of the river.

Thursday June 28th .. Teamed up with Ludwik Michalek again. We decided to survey one of the dismantled railway lines leading towards Clipstone Forest. Now part of the national cycle route, we picked it up leading north from the outskirts of Rainworth at SK605584, towards the south-west corner of the forest. Disused and dismantled railway lines seem to have gained near mythical status among naturalists studying Glow Worms elsewhere in the UK, so I was anxious to check yet another one, on my continuing quest to see if this assertion holds true for Nottinghamshire.

Access was very easy from a new build corner of Rainworth and once on the former colliery line, it quickly descended into quite a deep sandstone cutting with a mixture of tussock forming Grasses, Heather and scrub with some bare sandstone areas. After about a mile, the line met the point where Rainworth Water enters a culvert, to then head west down towards a water treatment works near to Rainworth Heath. From there we picked up the track leading east into Clipstone Forest, initially going under a concrete bridge carrying the rest of the former line north to Clipstone. Up to this point, no glow worms had been found despite some promising looking habitat in the cutting.

Passing three ponds to our left and Rainworth Water to our right, we headed into the south-west corner of the forest and quickly surveyed a small clearing under some trees. None there, so carried on to find our now familiar transect centred on SK616601 to find just one female in what was by this date, chest high bracken. Very difficult to survey, leading us to conclude that there may have been many more there, that we could neither see, or realistically find.

Returning to the main ride, we decided to continue surveying on our way back and were pleased to find 3 females in the bracken on the north verge of the ride and one on the south side, include one right in the middle of the path! Also much in evidence, several bright glows from larvae down in the short grass on the north verge edge. One located in torch light turned out to be just 10mm size and it was heartening to see larval hunting behaviour at Clipstone Forest, following the now familiar pattern seen at other sites locally and in captivity.

In conclusion, once again Glow Worms seem to be mostly confined to areas of the forest rather than tracks in open land. Despite surveying many disused mineral lines in Notts, I'm yet to find a single glow worm on one, but I'll keep looking. Finally a big thank you to Ludwik for again providing transport and his company on the evening.

2017 Survey reports from Martin Dale and Ludwik Michalek

Edited survey accounts kindly sent to us and originally written by Martin Dale.

Friday June 16th 2017 .. Quick visit to Thieves Wood and Normanhill Wood prior to Monday (June 19th) evening visit. Two lures checked after foray into Harlow Wood and towards a known Glow Worm site. We had recorded three females on the footpath leading to the colony's location within Harlow Wood. Afterwards we returned to our lures placed at SK546561 and SK547562 in Normanshill Wood, but no males were attracted.

Monday June 19th .. Went to Rob Lane, at first in daylight and left a lure in an open part of Comb Wood, running along side of Rob Lane. Site very remote and dark at night with good habitat, both along the lane verge and in the woodland.  We didn't reach the sunken part of the lane due to a heavily rutted track, but were within 100 metres of it. The 1992 report location of glow worms from SK630550 is now almost directly under a huge wind turbine and the lane up to the farm is managed with lawn and young trees.  No males to lure when we returned but lane and site was not fully surveyed for females due to late hour and long difficult track on our return.

After returning from Rob Lane we went back to Thieves Wood, concentrating on the transect between coniferous and deciduous woodland, roughly parallel with the A60 and placed a lure at SK547568. We then spent some time traversing the site looking for females. None found including the area directly opposite the path on the other side of the A60 where the three females were found in Harlow Wood on Friday June 16th. Despite this, no females were found in Thieves Wood, nor any males attracted to our lure.

Thursday 6th July 2017 .. Met Ian Major of the Sherwood Forest Trust and Norman of the Friends of Sherwood Heath group, in the car park of 'The Alders' public house, where we convened to begin a survey of Sherwood Heath for Glow Worms.  Following surveys of Sherwood Heath in June by Trevor and Dilys Pendleton and Ludwik Michalek, we were keen to find if they were still there following the sustained crash in numbers over the last 8 years from the high counts (200+ females) recorded on two nights in 2008. To assist in determining this, lures were placed in two locations, at SK644674 and SK 645676 to be checked later. One female was found by Norman at SK644674 and returning to the lures, one male was found at each lure, so at least they are still present on the site, albeit in much reduced numbers.

Friday 7th July 2017 .. Teamed up with Ludwik Michalek again, this time to survey the area around Loath Hill and Robin Hood Hill centred on SK634535 where there is an Iron Age hill fort and burial mounds. Lures were placed at 3 locations; SK634537, SK633535 & SK633532 but no males were attracted and no females found following an extensive search of the area. 

We also completed a more thorough survey of Combs Wood and the sunken part of Rob Lane, centred on SK641547. No lures were set but the full extent of Combs Wood was surveyed including the full length of Rob Lane from the east and west ends. The location of the 1992 Glow Worm record, is now at the foot of a very large wind turbine! No glow worms were found, although the sunken part of Rob Lane is well worth a visit for it's unusual character!

Nottinghamshire Glow Worm Survey results 2016

An enormous effort was put into the survey this year, especially by Martin Dale and Ludwik Michalek. Even though all of Martin's surveys produced negative results, they were useful in confirming that (around Nottingham at least) Glow Worms have certainly declined in recent years. The Holme Pierrepont and Colwick Park areas, seem to be less suitable now for Glow Worms, than perhaps they were a few decades ago.

Survey report from Martin Dale - Kneeton, June 6th 2014

Phil Parry and myself did a survey of the area of wood and flood plain alongside the south bank of the Trent called Watson's Piece. This was the location where a work colleague had reported seeing Glow Worms present in 2008. The location was accessed off the Kneeton Road between East Bridgford and Kneeton via Old Hill Lane - a track leading down to a large open field grazed by cattle. Historically, Old Hill Lane connected to one of the Trent's old ferry crossing points - the image of which can still be seen in the aerial view here; The area called Watson's Piece is partially in the flood plain of the Trent and on the wooded mudstone bank of Old Hill.

We surveyed Old Hill Lane itself and approx 1km of the adjacent flood plain and wood for Glow Worms between 22:20 and 00:10. None were found. The lower lying parts of the flood plain were totally inaccessible due to standing water, and much of the area extremely muddy due to recent rain and churning by cattle movement.

To the south-west of the area, we reached the enclosure that contained the location where Glow Worms had been previously recorded (SK697453). An established path was marked with arrow marker posts and a stile here; but the access through was severely restricted by overgrowth and high nettles making access near impossible at present. The likely presence of Glow Worms was inconclusive. Whilst the enclosed area did seem to be quite a haven for bird-life and has not been grazed, the nettles and overgrowth would not immediately suggest idealised Glow Worm habitat! We briefly checked out a track down to the other end of the site here; but the whole area of wood has been cleared and is now a crop field right down to the river.

Many thanks to Phil Parry for providing the transport for the evening and assisting in the hunt.

Nottinghamshire Glow Worm Survey results 2013

Unfortunately and despite much publicity, we had very few responses to the 2013 survey. Perhaps the real shame is that despite the large number of people being employed by conservation organisations, land/site management and wildlife groups, it seems that no one could spare just one hour, during the course of the Spring and Summer. However, despite this, four new Glow Worm sites were located within Clumber Park by Ludwik Michalek and James Glendenning and an additional three areas of Clipstone Forest/Sherwood Pines covered by Andy Lowe, were found to have Glow Worms.

The Nottinghamshire Glow Worm Survey results 2012

Survey sites away from Clipstone Old Quarter (not listed here) and providing negative results for Glow Worms are shown in grey. But there is always the possibility that Glow Worms could still be present at most of these sites given further surveys. Sites where Glow Worms were recorded are in blue. The lower site survey results, refer to searches for late females and/or larvae.
