Diary of a Heritage Intern

Chris Bradley – previous Building Conservation Intern

Having completed my Masters degree at the University of York I was excited to be applying for jobs and starting a new career. After a year of applying and volunteering, I Chris in his natural habitat - Ryedale Folk Museum, Hutton le Hole.was elated to get the opportunity of an internship with the North York Moors National Park Authority.

Meeting the Building Conservation team was great, they were friendly and encouraging and offered to help in every way possible whilst of course keeping to the social restrictions in place. My mentors, Maria Calderon and Clair Shields, presented a clear desire to provide a practical opportunity for new starters in the heritage sector which is something that I have found to be limited in my time searching for work.

My main objective was developing a Conservation Area Appraisal and Management Plan (CAAMP) for Hutton Le Hole. Having read and interpreted some of these official documents for past academic research I was both excited and nervous to be able to produce something that would inform and offer professional guidance whilst finally gaining experience in the career path I wanted to follow.

The first week revolved around researching the history of the village and going out to see the area in person to understand the full scope of the work. The initial research phase felt instinctual, reminiscent of my previous studies and was a comfortable start to my internship. For the initial walk in Hutton Le Hole I met up with the team to get my bearings and discuss the vision and style of the Conservation Area which helped settle my nerves as we all had similar thoughts as we walked around. The starting week was informal and friendly which helped me to quickly settle in and feel like part of the Building Conservation team.

The following few weeks I began to work on my own with supervision meetings with Chris (in the distance) appraising the beckside fencing, a feature of Hutton le Hole.Maria periodically who really helped to encourage me and regularly offered some much needed advice. Through my second week I felt my work had been making slow progress into the Conservation Area Appraisal. But I then started to create my own schedules and push myself to reach bigger targets each day. My first site visit alone felt like a big and unorganised mess, I found the hours of the day had passed but I had hardly made any progress giving me cause for concern about my deadline. However, as with everything new, this quickly changed once I had a routine and the workload soon felt manageable and was an interesting and fun job to produce and complete.

Come the sixth week I had completed a draft of the CAAMP and got the opportunity to expand my experiences with using a Geographical Information System (GIS). This is something I had only heard of briefly through my studies and through applying for jobs. I had zero experience and I believe this was just as useful to practice as the Conservation Area Appraisal process. Using the Authority’s Earthlight system, under the supervision of Nick Mason the Archaeology Officer, I was tasked with plotting and producing information for the non-designated local list for the Hutton-Le-Hole parish. This, again, was a fun task to take part in and I enjoyed the opportunity to gain the additional knowledge. I knew the Conservation Area very well at this point but now I had to expand this to the whole parish, being able to explore and research the wider setting was now easier having gained the experience of recording the data for the Conservation Area already.

By my final week I had completed the Conservation Area Appraisal documents and the non-designated local list. So I got the chance to review and discuss planning applications with Maria. This gave me an insight into how the Building Conservation Team works on their more regular tasks, giving me more opportunities than planned within the time of my internship.

My internship was a fully positive experience and offered more than I expected in the time frame. I am very grateful to have been given the opportunity by Maria and Claire and I feel I have built strong relationships with them both within the short period of time at the North York Moors National Park Authority. I hope this can become a regular internship there where they can offer more experiences and, more importantly, encourage others to get involved in heritage.

Our Ryevitalise Landscape Partnership Scheme has been active now for over 16 months; it’s had quite a time so far. We thought it would be courteous to introduce the very adaptable delivery team.

“I’m Alex, the Programme Manager for Ryevitalise. My main role is to work closely with all of our wonderful partners and the National Lottery Heritage Fund to deliver our Ryevitalise vision to ‘conserve, enhance and restore the natural and cultural heritage of the area, enabling people to reconnect with the history, wildlife and landscapes of the River Rye and its tributaries’.

I’ve always had a passion for nature. Growing up locally I have great childhood memories of taking part in lots of activities with the North York Moors National Park. In my early teens my family moved to the Falkland Islands where I was fortunate to volunteer for Falklands Conservation, spending days on end undertaking penguin chick census checks … it was amazing! My family then moved to Ascension Island where I carried out bird, turtle and endemic plant counts, and these experiences led me to pursue a career in conservation.

Alex Cripps, Ryevitalise Programme Manager. Copyright NYMNPA.I studied Environmental Science at the University of East Anglia, including a year in Canada – my dissertation focused on the impacts of habitat fragmentation on ungulates (moose, elk and deer) near Banff National Park. I then spent two years travelling and working in New Zealand before I decided I’d better get a ‘real’ job.

I was delighted to be offered a job in 2013 working for the North York Moors National Park as their Conservation Graduate Trainee. Since then I have developed a huge passion for rivers; I became the Esk and Coastal Streams Catchment Partnership Officer in 2014 before taking on the role of Ryevitalise Catchment Restoration Officer in 2017, part of a small team to develop Ryevitalise. In 2018 the final Ryevitalise application was submitted and now here we are, delivering this ambitious landscape partnership scheme and it’s great to be leading the team as Programme Manager.

I love sharing my enthusiasm for rivers and the fascinating wildlife that our freshwater habitats and surrounding areas support. For those of you who know me you will know that I absolutely love aquatic invertebrates – one of my favourite moments in the Rye catchment was watching mayflies dancing above the River Rye near Helmsley, there’s nearly always a dipper bobbing about here too.

Ryevitalise will be raising the profile of rivers, looking at how valuable these ecosystems are and how important they are to local communities. We will be working alongside local communities, including land managers and young people, reconnecting people to their local river systems and exploring how simple every day actions to help care for our rivers can collectively make a huge, positive difference. So it’s great to be underway, delivering a wide variety of projects, and I look forward to meeting some of you soon!”

“Hi everyone. My name’s Paul Thompson and I’m the Programme Officer for Ryevitalise currently overseeing our ancient woodland restoration work, access improvements, and community arts project. I’ve also been supporting land managers in Bilsdale carrying Paul Thompson, Ryevitalise Programme Officer. Copyright NYMNPA.out habitat improvement works. I’ve been really inspired by our community who care passionately about our local heritage and rural landscape. Finding solutions to key conservation challenges that benefit people, the economy and the environment is incredibly rewarding, and demonstrates the power of National Lottery Heritage Fund’s landscape partnerships.”

“Hello! I’m Amy, Ryevitalise Education & Engagement Officer; my job is exactly what it says really. Anything from working with schools, volunteers, local communities, running events and bit of historical work thrown in for good measure!

I started conservation life as a seasonal ranger for the National Trust on the lovely South East Cornish coast. Then moving closer to home to work for the Tees Valley Wildlife Trust as part of the River Tees Rediscovered project. All my roles have involved people (and rivers) in some way! Whether it’s bossing… I mean working with… volunteers; mammal surveying, running community events or working with local people of all ages. I love seeing folks reaction to the first path they have built, catching their first tad pole or that first cup of tea after a gruelling task. It’s amazing how inclusive conservation can be; wildlife doesn’t care who you are or what you can do.

Having spent many of my days as a teenager walking the Cleveland Way and hiking up Hasty Bank, it’s great to actually work here and show off what a lovely place the Ryevitalise area is!”

“Hi! I’m James and I’m the Catchment Restoration Officer. Essentially my job involves working to improve the water quality of the River Rye by engaging with land owners, whether by creating conservation agreements which typically address point source James Caldwell, Ryevitalise Catchment Restoration Officerpollution issues, promoting opportunities to increase habitat connectivity, controlling invasive species, or helping to create a more natural river by removing obstacles to fish migration.

I had a rural upbringing and have always had a passion for the environment which is reflected in my career choice, starting as an assistant ranger for a trust in Peterborough, moving to a countryside ranger position with a borough council in Surrey and most recently settling at the North York Moors National Park Authority. 

I enjoy exploring, whether walking, running or cycling, and am delighted to have such variety on the doorstep that also forms my wider “office” and supplies great photo worthy content.”

“Hi everybody! I’m Sam Lewsey, the Field Officer for the Ryevitalise project and my main areas of responsibility are the citizen science programme, and the delivery of practical works with our wonderful volunteers.

Sam Lewsey, Ryevitalise Field OfficerI came to the North York Moors from the National Trust, where I worked as a Ranger for the last few years, and before that I worked for Cambridge University. Both my parents had a huge love of the great outdoors and natural history, and this was something I picked up from an early age. I am passionate about wildlife and love working with volunteers setting up programmes of surveying – developing my own ID skills and helping others develop theirs. Hay meadows and their associated pollinators hold a particular fascination for me. When not crawling about looking at wildflowers and fungi you’ll find me out on a run – the longer and hillier the better!

If you’re keen to get involved in volunteering with us please give me a shout and I can talk you through the opportunities that are available within this fantastic scheme.”

“Hi everyone – my name’s Ann Pease and I am the Administration Assistant for Ryevitalise, overseeing all of the background paperwork that keeps the project ticking Anne Pease, Ryevitalise Administration Assistantalong! One of my many roles is liaising between the team and the National Lottery, helping to collate and provide the evidence needed to receive our funding. 

I’ve volunteered for many years across the conservation sector – and am over the moon to be able to work on a project having such a positive effect on our areas landscape and wildlife. 

Being a local girl I am deeply connected to this landscape – I’ve spent much of my life up on the North York Moors and it’s great to see this project champion what makes the area so special. 

If I’m not working you’ll probably find me out walking somewhere – I am a big fan of National Trails and long distance walks…I am also a big fan of butterflies, moths and birds of prey and never miss a chance to have a bit of a geek out!

At the moment I am on maternity leave having had a baby boy in July (mid lockdown!), so am watching from afar – but am very much looking forward to being back in February to see how the project is getting on…”Ryevitalise logo banner

No lockdown for Ring Ouzels

Vic Fairbrother, Ken Hutchinson and the Updale Natural History Recorder

We have been studying Ring Ouzels on the North York Moors for over 20 years. This has involved intensive fieldwork every week throughout each breeding season, commencing before the birds return from North Africa in order to establish first arrival dates. Courtship behaviour, nest building, egg laying, the hatching and fledging of chicks and levels of predation have all been carefully monitored. Simple and complex song was also recorded and analysed and the presence of a local dialect established. Conservation measures were identified and implemented. Although our intensive study had ended, we had hoped to continue to maintain a general overview of the Ring Ouzel’s foothold on the North York Moors again this year.

An early indication of problems ahead came when the annual meeting of the UK Ring Ouzel Study Group in Penrith on 21 March this year was cancelled in view of the imminent pandemic lockdown. Shortly afterwards, the BTO and RSPB suspended all survey work, nest monitoring and bird ringing and it became clear that our own observations were also going to be severely affected.

Although our ability to monitor them this year has been severely disrupted, this remarkable bird’s annual struggle for survival has continued on our doorstep.

It was sunny with a cold wind in Rosedale on 21 March and with travel about to be severely curtailed, it was cheering to watch Curlews and Lapwings back on their upland breeding grounds but even more special was the sight of two Wheatears which are often the first migrants to arrive back in the dale. Sudden chacking at Nab Scar then revealed the exciting sight of the first Ring Ouzel of the year to return to Rosedale from their winter quarters.

As more ouzels gradually returned to local sites, small groups of ouzels (presumed to be passage birds i.e. migratory birds on their way to somewhere else) were also reported from a number of locations during much of April.

With restrictions still at a high-level, the permitted daily exercise walks provided a real treat on 29 April, when a female Ring Ouzel was observed gathering nesting material at Sturdy Bank and taking it to a suspected nest site whilst the male was singing nearby. A week later, the female flew into this suspected nest site where she remained and was presumed to be sitting on eggs.

During the next few weeks, territorial behaviour by two more pairs of ouzels was also reported from Reeking Gill and Reeking Gill South and with the easing of restrictions in mid-May, slightly more detailed monitoring was enabled.

An increasingly rare sight and an experience to treasure occurred on 27 May, when a pair of Cuckoos flew in towards Reeking Gill, the male calling beautifully. When he came to the south end of the embankment a male ouzel promptly chased it away. A few minutes later the male Cuckoo returned to land on a rock just inside the entrance to the gill. As walkers approached, he flew higher up the gill to land in the rowan tree opposite a first brood nest site, at which the second male ouzel immediately chased it down and out of the gill.

Cuckoo, Rosedale. Copyright Vic Fairbrother, Ken Hutchinson and the Updale Natural History Recorder.

Three days later two female ouzels were being closely watched at Reeking Gill. A male and at least two fledglings could be seen below the first brood nest site high on the north east side when one female flew up the gill and straight into a new and presumed second brood nest site, almost opposite the first brood nest site and close to where the Cuckoo had been evicted on 27 May. To our great surprise the second female then gave her nest site away by flying straight in to heather just outside the south east entrance of the gill and in the vicinity of the other Cuckoo altercation. The discovery of these new nest sites explained the agitated behaviour of the two male ouzels towards the Cuckoo a few days earlier. Later, the two male ouzels were heard counter-singing.

The welcome easing of restrictions eventually enabled eight nestlings to be fitted with BTO rings at Sturdy Bank and Reeking Gill. The three nests here and the one at Sturdy Bank all fledged young but a nest at Reeking Gill South was predated. Fledged young were also seen at Bank Top, Hob Crag and Blakey on the west side of Rosedale, along with a number of rather inconclusive ouzel sightings. In view of the many constraints it is almost certain that other breeding attempts went undetected in the study area this year.

Ring Ouzels switch to eating berries as they prepare for migration and during our study, we had become concerned at the lack of regeneration among the scattered rowan trees in the study area.

The Ring Ouzel’s remarkable link with the industrial heritage in Rosedale was recognised during the Land of Iron Landscape Partnership Scheme, funded by the National Lottery Heritage Fund. We were delighted when as part of a number of biodiversity initiatives a small-scale tree planting project was developed in an attempt to provide a sustainable supply of rowan berries here.

Copyright Vic Fairbrother, Ken Hutchinson and the Updale Natural History Recorder.It was a sunny day but with a strong chill breeze from the south west when on 3 September we decided to check how well the rowan tree planting was faring. There were widespread reports of good berry crops elsewhere and as we descended below the railway track and worked our way towards Blakey Swang from the south, we could see that the surviving mature rowan trees here were a splendid sight.

We then turned our attention to several small enclosures and scattered individual saplings carefully placed in the vicinity of mature trees along the steep escarpment. In some of the small enclosures we could see that numerous strong saplings had grown well above the tree guards. Vic pointed out a particularly healthy group in one of the highest enclosures and Ken looking through binoculars observed that one bore a small clump of berries. At first, Vic thought that he was joking but the first fruits of the planters’ efforts were there on display. He could not resist the impulse to climb the steep bank for a photo.

A poem from the North York Moors

What is the sky?

Everchanging and expressive,
space and heaven combined.
Infinite and important,
vast desert on high.

Mother Nature flaunting her power,
April showers, hurricanes and storms.
Summoning angry clouds, heavy with rain,
Later filled with light, warming your bones.

Blustery winds and excitable gusts,
fresh air fills and cleanses the lungs.
Billowing clouds, creating beams and rays,
dappled across the undulating land.

Everchanging season casting shifting light.
Rainbows, shooting stars and Aurora Borealis
flashing colours over the great canvas.
Heaven’s glory or natural phenomenon?

Streaked with man’s machines, airplane trails,
aerials, satellites and drones.
Great machines can’t compare
nothing more than flecks on this dome.

Sunrises and sunsets marking our days,
celebrating with glorious colours.
Ink-washed turning to boundless jet black,
encrusted with the finest jewels ready to wish upon.

Way! Hey! It’s Lamprey!

Amy Carrick – Ryevitalise Education & Engagement Officer

My friends in the world of fresh water have always tried to convince me that lampreys are beautiful creatures that are an essential part of our eco-system. I was somewhat unconvinced! Their slippery skin, suckers and razor teeth never quite made them the most attractive of animals. Having grappled with measuring elvers in plastic trays in the last Ryevitalise blog post, I was never convinced that neither eels nor lamprey were anything other than something out of a horror film. However whilst Riverfly monitoring on one hot sunny morning recently along with one of our (socially distanced) experienced volunteers, we came across one of the blighters. Even though notoriously difficult to catch, one landed right in our net after our 3 minute kick sample. As our volunteer excitingly popped it onto his hand and waved it in my face, I really wasn’t sure why he was that excited … so he explained how fantastic they were for our rivers.

So why the Rye?

Firstly we have three species of lamprey in this country – sea, brook and river lamprey. These have been a rare sight recently in this area until the past few years. As a result of an improvement in water quality, the removal of migratory obstacles and the installation of special tiles that help movement, the lamprey are navigating through the River Derwent. The population has become so important that the lower reaches of the Derwent now have protected status, reflecting the spawning distribution of the species in the catchment.

That this ancient species has made it back up to the River Rye towards the top of the Derwent catchment is very encouraging. Small numbers have been recorded in the past few years by our Riverfly monitors.

So why should we care?

Well over the past few decades high levels of pollution in our rivers has nearly wiped out any chance of seeing lamprey in the UK. All species of lamprey require clean sandy gravels to spawn. The young larvae then swim off to the soft marginal silt of the river to grow; feeding on the algae, bacteria and detritus. Sediments can also smother spawning gravel sites, also effecting other species of fish too. Dramatic changes in water flow and levels also affect these spawning sites. The migratory sea and river lamprey require good water quality to survive their long journey from sea to spawning sites.

This means that if you do have lamprey in your river, something is going right!

So what can we do to help?

Although the fate of the lamprey population depends on the goings on in the lower catchments, the more we can do in the upper catchments to keep lamprey here the better for our freshwater ecosystem, and that’s exactly what the Ryevitalise Landscape Partnership Scheme is trying to achieve. The reduction in sediments is one of the biggest factors; reducing Himalayan Balsam eroding our river banks, stopping cattle predation in rivers, changing the way riparian land is farmed to reduce runoff, all helps in the battle against sediment. Water level management and the planting of trees also helps with reducing the dramatic water level changes during the winter. And most importantly (slightly biased) is engagement! If people don’t know why we should care for lamprey, then they never will. Sharing the beauty and importance of this slippery creature with as many people as possible will help in protecting these quirky river species.

Did you know for example lamprey predate dinosaurs by 200 million years?! And my favorite – apparently during the Middle Ages, lampreys were widely eaten by the upper classes throughout Europe. It is thought King Henry I died from overindulging on lampreys.

So while I will still recoil in horror at seeing one, I now know how special lamprey are and I will attempt to make these as popular as the cuddly otter or water vole….well one can try…..

A miscellany of wildlife encounters

During the last few months, alongside everything else that has been going on, there has been the chance for additional up-close and personal nature experiences. Here’s a few from the (mostly) home life of the Conservation Department – some in pictures some in words.

Here’s a stunning patchwork green view that could be seen when looking over towards Whitby from Borrowby while completing a grassland survey. Copyright Victoria Franklin, NYMNPA.

Golden ringed dragonfly being pointed at. Copyright Rachel Pickering, NYMNPA.“A golden ringed dragonfly let both our children [very gently] touch it. For me I guess one of the more striking things about this encounter was that we were in Cropton Forest – part of Forestry England’s ‘commercial conifer forestry’ which some people write off as having no wildlife value. My family and I have spent many happy hours in Cropton Forest during the past couple of months enjoying wildlife and cultural heritage and just for that time not seeing another soul.

There was a nesting blackbird squashed into a hole in a wall in my parent’s potting shed which successful fed and raised a brood of chicks. On our usual dog walk near home we came across a cobweb of small eggar moth caterpillars. We took some home for a week or so and they enjoyed living in our kitchen fed on blackthorn. We let them go back into the hedgerow when we realised that when they form a cocoon they stay in it overwinter and perhaps even for 2 or 3 winters! So much better off back in the hedge.”

“Last week after a dawn bird survey I stumbled across a fantastic small quarry … With three species of orchids; Bee, Butterfly and Fragrant (maybe Chalk Fragrant) … I was as they say Well Chuffed!”

“I’ve been seeing loads of wildlife; it’s photographing the pesky thing’s that’s the problem – for some reason they don’t seem to want to cooperate! There’s the barn owl that’s been hunting at the bottom of the garden and in our neighbour’s field almost every morning and evening for the past couple of months; I’ve seen more badgers this year whilst out running than ever before, including an adult with two cubs; then there’s the hare that’s taken up semi-permanent residence on the lawn; the herd of 10 fallow deer in the barley field next door that I see from the kitchen window most evenings; and I’ve been dived bombed by lapwings when running on the moor above Kepwick.”

“I came across this delightful critter in my garden yesterday – it’s a Nicrophorus Nicrophorus Investigator. Copyright Briony Fox, NYMNPA.Investigator – it is a burying beetle and like other burying beetles they bury the carcasses of small vertebrates such as birds and mice as a food source for their larvae. They are common and widespread (although I’ve never seen one before!). They have a very good sense of smell and are reputed to be able to smell a carcass up to two miles away (ewww!). It was quite a big bug – around 2cm long.”

“I had a rather unpleasant wildlife encounter at Falling Foss on Thursday when our friends dog ‘found’ a nest of agitated bees on the path and they swarmed and chased us. I evaded the inevitable but the others all got stung so that wasn’t fun. We did see a toad later on so that made up for it a bit!”

“Me and my family have spent hours watching the wildlife in our garden and in and around the village throughout lockdown, this is my favourite event because I love a happy ending…We have a troop of sparrows who eat their way through a big feeder of bird seed every day. I enjoy watching them line up on twigs waiting for a go and squabbling over the perches on the feeder. They have a dust bath under the hedge often alongside our chickens. The group fledged lots of young and my two children loved watching the fluffy youngsters hanging around under the feeder waiting for attention from their parents. Just before the children’s bath time one day we heard a loud thump on the lounge window. I ran out followed closely by the children and found a stunned just fledged sparrow lying on the ground. I picked up the little bird and we all peered down at her – she opened an eye! We decided to put her in a big cardboard box while the children had their bath and see what happened . . . After the quickest bath on record we opened the box and there she was standing up and looking up at us. The children carried the box out into the garden and off she went back to the troop…”

Swallow Beard - Alasdair wearing a swallow chick. Copyright NYMNPA.“Earlier in the year I had about 50 whooper swans fly low over the house! What a noise! I’ve had a pair of redstarts nesting in the eaves of the house…A pair of swallows built a nest in the chicken coop and the chicks fled the nest early to escape the temperature of a hot day (nest was very close to the tin roof). So I moved the nest, scooped up the chicks and popped them back – one got attached and found comfort under my beard for a while before I popped it back with siblings – happy to say all four have fledged! Good work mum and dad!

Being at home more has meant that I’ve gotten to see the green woodpeckers more often rather than just hearing them ‘yaffling’ in the woods…”

“My main experiences with wasps have mainly been negative…it normally involves providing a glass of sacrificial cider to keep them at bay in the beer garden on a sunny afternoon. They also act as play things for my cats when they invade my house. I don’t know much about wasps but never the less I know how important these little beasties Alex's wasp nibbled bird table. Copyright Alex Cripps, NYMNPA.are, although trying to explain that to anyone outside of the conservation sector can prove challenging. Whilst attempting to tackle my garden I noticed my log bird table had slowly started to shrink, once a solid round log was now two thirds of its size. I assumed I was not feeding the birds enough food and they had taken to destroying my table as a form of protest, until I noticed a wasp happily munching away at the wood. I was unsure why a wasp might have taken a liking to my bird table until I stumbled across an episode of Springwatch where Chris Packham was stood excitingly next to a wasp having a good old munch on his old shed door. I didn’t realise that this ritual was part of the nest building process until seeing that episode, so although my bird table is not as smart of it used to be, it’s great to see nature in action!”

“No major surprises but it’s been a lockdown pleasure to watch goldfinches, tree sparrows, magpies, wood pigeons, doves, crows, etc. pop into the garden and the occasional herring gull pop down to eat any scraps left out and remind me just how big they can get! We also have three cheeky hens who are resident in the back garden…We’ve also had a few visits from hedgehogs in the front garden, including one who popped by at 5pm for a quick snuffle in the soil – we haven’t actually seen a hedgehog in the front garden for quite a few years now, so our late afternoon visitor was quite welcome. There was also some distinctive paw prints left out on the front step one night and we think it had popped back for some more exploration. We’ve also had rabbits in the garden too, probably from the close-by cemetery which is home to a few. Last weekend I joined a small group of friends in a mates back garden to celebrate his birthday and at dusk we had the pleasure of watching the local bats pop out and skitter around the sky for insects – one bat came very close to brushing all of our faces with its wings as it did a loop around the table top! I’m presuming they were common pipistrelles, we have them at home too and they have been a delight to watch.”

“In my tiny garden I’ve had three blackbird nests, one thrush nest, and two robin nests … and the butterfly is a common blue seen in a quarry near my house.”

Ephialtes manifestator. Copyright Sam Newton, NYMNPA.“I’ve had lots of red mason bees and leaf cutter bees using my solitary bee ‘hotel’ and holes drilled in the fence. While watching them a few weeks ago, an impressive parasitic ichneumon wasp called ‘Ephialtes manifestator’ visited and started laying eggs in some of the full nesting tubes. I’ve since found out that it’s only the 10th record of this wasp in Yorkshire, so I’m really pleased that I’m helping support these associated parasitic species as well.

More small eggar moth caterpillars. Copyright Sam Newton, NYMNPA.I ventured on a few new footpaths not far from home, and on one came across a really nice veteran oak tree. While looking at it, I found a number of deathwatch beetles on it – which this far north are very rare in natural situations (i.e. not eating National Trust properties!) – so were quite an exciting find (for me anyway!).

When lockdown began to ease I spent some time looking for small eggar moth webs in the nearby hedgerows, and have also reared some caterpillars. They’ve all pupated now, but they kept me very busy as they ate an immense amount and needed daily supplies of fresh blackthorn!”

“I saw a hedgehog as I was leaving a site visit in Bilsdale last week, makes a refreshing change to see a live one rather than the many killed on the roads.”

Not all the species have been rare and not all the locations special – but each encounter made an impression.

Microscopic wildlife

Recently the Hoopoe blog by NHBS hosted an interview with Ben Fitch, the Riverfly Partnership’s Project Manager.

Ben emphasis how important riverfly monitoring is as an initiative because it is such an effective way of monitoring the health of a river through its fly life. Ben also happens to mention the flat-bodied mayfly larva (Ecdyonurus dispar – Autumn Dun) as one of his favourite river flies, particularly the white-spot variant.

Excitingly during a socially distanced riverfly training session a few weeks ago Alex, Sam and Amy from the Ryevitalise Team found this very variant here in the River Rye. Apparently the exotic looking spots might be caused by a recessive gene, but what triggers it remains unknown.

Riverfly monitoring in the Rye catchment is getting going again now, whilst keeping in line with current Covid-19 restrictions. So we thought we’d have a chat with one of our own riverfly people – Sam Lewsey, Ryevitalise Field Officer.

Riverfly monitoring in the Rye Catchment. Copyright Sam Lewsey, NYMNPA.How long have Riverfly volunteers been out in the Rye catchment this year?

We started the phased return of riverfly monitoring from the middle of June. Amy (Education and Engagement Officer) and myself have been meeting individual volunteers on site to go through revised risk assessments and answer any questions they may have, as well as conducting the first kick-samples of the year. Normally riverfly monitoring would have started up at the beginning of May, but due to restrictions our volunteers understandably weren’t able to get out and monitor for the first 6 weeks of the sampling season.

How many Riverfly volunteers have you got on the Rye?

Currently we’ve got 30 riverfly volunteers registered through the Ryevitalise programme, although not all of these are currently ‘active’; unfortunately due to C-19 we had to Riverfly monitoring in the Rye Catchment. Copyright Sam Lewsey, NYMNPA.cancel our riverfly training and refresher days in April, so some volunteers are still awaiting their official training, including health & safety. Others have received training previously and are in the process of being assigned a site to monitor. Our first phase of volunteers to get back to volunteering were our established riverfly volunteers (8 in total) at sites where they had monitored before.

Riverfly monitoring is a good thing because…

“Riverflies (and other freshwater invertebrates) are at the heart of the freshwater ecosystem and are a vital link in the aquatic food chain. Because riverflies are riverfly populations are affected by many factors, predominately water quality, habitat diversity, water level and flow rate. Their common characteristics of limited mobility, relatively long life cycle, presence throughout the year and specific tolerances to changes in environmental conditions make them powerful biological indicators to monitor water quality, and so are commonly referred to as ‘the canary of our rivers.’  The Riverfly Partnership spearheads an initiative to allow interested groups to take action that will help conserve the river environment. This initiative provides a simple monitoring technique which groups can use to detect any severe perturbations in river water quality…”

Basically this Citizen Science initiative “ensures that water quality is checked more widely [than it would be otherwise] and action taken at the earliest opportunity if any problem are detected”.

Ryevitalise is participating in the national riverfly monitoring scheme run by the Riverfly Partnership. It’s important that we’re part of the wider scheme for several reasons: it standardises the methodology used across the UK; we get top-notch training and support from the Riverfly partnership’s extremely knowledgeable qualified trainers; we can run reports of our results easily from the database that our result go into; and we get to contribute important data on water quality and catchment health to the wider national scheme so that research into trends in the health of our rivers can be carried out and lead to informed changes and positive impacts on terrestrial and aquatic management.

Riverfly monitoring focuses on three groups – the up-wing flies or mayflies (Ephemeroptera), caddisflies or sedges (Trichoptera) and stoneflies (Plecoptera).

Such tiny creepy insects are actually fascinating and wonderful because…

Good news story: Turtle Doves in a weedy corner

Richard Baines – North Yorkshire Turtle Dove Project Officer

On 24 June I got a text message from one of our Turtle Dove volunteer surveyors. The message went something like…

‘A good morning’s survey – I saw five Turtle Doves including two feeding alongside eight Yellowhammers in a weedy corner of a nearby field’.

I was very pleased Andy had seen five Turtle Doves because that was one more than I had seen in the same survey square the previous month. But hang on a minute … ‘feeding in a weedy corner’ ?… that phrase pushed me to the edge of my seat … I messaged Andy back and asked him to send me a map of where they were feeding … as soon as I saw the map, I gave a big hurrah!!!

The ‘weedy corner’ was in fact the wild flower plot sown in the last couple of years by a farmer especially for these endangered birds as part of the grant scheme through the North Yorkshire Turtle Dove Project. Even better – Andy had actually got a photo of one of the doves (see below), great evidence of success! I rang up the farmer to give him the good news – not surprisingly he was very pleased that his hard work was having the desired effect. The flowers in the mix he planted include Turtle Dove favourites such as Common Fumitory, Black Medick and Birds-foot Trefoil. Three species which were once commonly found by the side of arable fields but are now increasingly rare.

The farmer and I had located the flower plot in one of his arable field alongside Forestry England woodland. This forest-farmland edge is a habitat known to be favoured by Turtle Doves, and other species such as the Yellowhammers Andy had also seen.

Our Turtle Dove Project has been overwhelmed by the good will shown by local communities and farmers. Now we have direct local evidence showing that these wild flowers and their seed really do make a difference for these beautiful birds when it comes to feeding – so we can continue our work with an extra spring in our step!

Sweetening the land

Ellie Leary – Monuments for the Future Project Officer

Not all of the archaeology within the North York Moors is as ancient and enigmatic as the standing stones or rock art (see previous posts). Once a ubiquitous presence within the landscape, you can still stumble across the remains of a more industrial feature – lime kilns. These structures were part of an industry that has shaped and changed the landscape of the area from the extraction of the limestone from quarries to its end use as a building material and soil improver.

Over 400 lime kiln sites are recorded within the National Park’s Historic Environment Record, with the evidence coming mainly from historic maps, but also earthworks and standing remains. Only three of these kilns have the benefit of protected status as Scheduled Monuments, and in all cases they are included as part of a wider monument rather than in their own right. Another three have protected status as Grade II Listed Buildings.

The use of lime has a long history in Britain dating back to at least the Roman period and over time it has had a wide range of practical uses from forming the base of plasters, mortar and concrete; as lime-wash for waterproofing walls and lightening interiors; in the bleaching of paper and preparing hides for tanning; as a disinfectant; and as a soil improver for agriculture.

During the Roman period it was used particularly for lime-mortar, plaster and lime wash; while during the mediaeval period the need for quantities of lime hugely increased with the construction of large stone-built buildings and bridges. From the 17th century onwards however the main use of lime has been in agriculture, with it being added to soil to improve acidic soils or as a top dressing to pasture to “sweeten” the land.

In most cases in order to turn raw limestone into a useable product it has to be fired in a kiln, creating a process called calcining where calcium carbonate is converted into calcium oxide. This process was both labour and fuel intensive and the trade was known as lime burning – those working at the kilns, were lime burners.

Most of the kilns known of within the North York Moors date to the 18th and 19th centuries, although earlier examples do exist. Excavations at Ayton Castle, for example, revealed a lime kiln dated to the 14th century, which may have produced lime mortar and cement for the construction of the castle’s tower house, the ruins of which still stand.  (This is one of the three kiln sites included within a wider Scheduled Monument – see above).

The earliest kilns were simple clamp kilns which consisted of a circular or rectangular hollow within which the limestone and fuel were layered, covered with clay or turf, and left to burn for a few days. Often clamp kilns leave little obvious trace, however the remaining protected kiln sites in this area (as mentioned above) include two clamp kilns built into the bank of a scheduled prehistoric cross dyke and another cut into the edge of a scheduled Bronze Age barrow – the actual kilns are all thought to be 18th or 19th century in date. Their remains can be seen as horse shoe shaped mounds of earth and stone rubble.

As the demand for lime increased kilns became more substantial in size although the transformation process remained the same. Kilns were generally circular or square stone structures, about 3m in height, with a bowl lined with sandstone or firebricks and at least one draw hole located at the bottom of the kiln. As the contents burnt through the lime was extracted through the draw holes at the bottom. Additional layers of stone and fuel could be added to the top if necessary, otherwise one-off firings were carried out as needed. A good example of this kind of kiln can be found at Old Byland where the remains of four lime kilns stand next to a road (see image below). They are located on the edge of a quarry to the south west of the village and some parts survive to 5m in height, with two of the kilns having the roof and flue surviving.

The end product removed from a kiln was called ‘lump lime’, ‘burnt lime’ or ‘quicklime’ and in order to convert this for use it has to be ‘slaked’ – a process involving adding water to cause a reaction which produces heat and steam. By then adding enough water, putty is produced, which, mixed with sand, produces a mortar. Over time this reverts back to calcium carbonate and hardens.  When used in agriculture the ‘lump lime’ was left in heaps, covered in earth and left to slake, eventually creating a powder that could be ploughed into the soil. Other methods were used too, including leaving the lime uncovered and occasionally turning to produce the same result.  ‘Lump lime’ is a volatile material and there were inherent dangers if it started to ‘slake’, producing heat, before it arrived at the final destination.  By the late 19th century, hydration plants were introduced that could grind the lime, sprinkle it with water, dry it and then bag it for transporting.

The location of kilns largely depends on the final use for the ‘quicklime’, so that if it were needed for building construction the kilns would most likely be located close to the building site. They could then either be dismantled and moved or left to decay once they were no longer needed.

Field kilns were sometimes built by farmers and land owning estates from the 17th century. Smaller kilns would have been built by farmers for occasional use to improve their land but estates often built larger kilns to serve the whole estate and wider area, providing a profitable source of income.

Another common location for kilns was close to or within limestone quarries. Many of these quarries are still obvious on the ground now as large excavated pits; historic mapping helps to identify the full extent of the quarries and the location of kilns. The 1893 Ordnance Survey map (below) shows Sour Ley Quarry near Helmsley with up to 20 lime kilns within the quarry.

Extract from 1:2,500 Ordnance Survey Map 1893

Easy access to transportation was also another consideration for the location – for fuel to be brought in and for the final product to taken away for sale.  Colonel Sir Joshua Crompton, 19th century owner of the Kepwick Estate on the western edge of the North York Moors, built a railway line in the early 1820s which carried limestone from a quarry on Kepwick Moor down to the lime kilns and stone yard to the west. Fuel for the kilns could be easily brought in and the final product taken away on the Thirsk to Yarm turnpike road (now the A19). With a very steep incline up to the quarry the railway used gravity; as the full wagons were sent down slope they pulled the empty ones up towards the quarry, whilst horses pulled the wagons along the flat plain to the west. The quarry and the start of the now dismantled railway line lie with the National Park boundary and the lime kilns themselves are a short distance outside the boundary and are protected as a Scheduled Monument.

As the demand for quicklime grew the process became industrialised, with new kilns designed with efficiency in mind as well as a higher quality lime product. As a result most of these smaller local kilns were abandoned by the 20th century, with some being dismantled and others left to decay, remaining in the landscape as a reminder of this chapter of industry.

Biological recording for the soul: recording nature – Part Two

“Biological recording on a national scale enables effective nature conservation”

Sam Newton

Sam Newton – Land of Iron Natural Heritage Officer

Like I said last time you still don’t necessarily need to go far to observe nature.

If you can identify wildlife as you come across it then you can add to a growing wealth of knowledge. The basic ingredients you need are:

  • what you saw
  • where you saw it
  • when you saw it
  • who saw it

Then all you need to do is submit these details. There are many different recording societies and schemes, but if you are new to biological recording, the easiest way to start is uploading records to iRecord (also available as an App). Uploading photos with your records will help the experts who will check your records. iNaturalist is an alternative for uploading pictures of species you have not been able to identify, and then other users of the site can try and identify them with you.

Please note – we do know what most of these are – but we left them un-named so you can have a go yourself.

Being able to observe and identify a plant or animal species, and in doing so understand a bit more about nature, can be incredibly satisfying. But you don’t need to act in isolation – other people are already doing this and can help and encourage with their expertise, experience and enthusiasm. There are a number of really great local and regional naturalist groups that are interested in the species you are perhaps most likely to encounter in your garden and nearby outdoor spaces. Things to remember are that not all species can be identified from photos, and if you use one of these sites, please read any introductory information or pinned posts to find out precisely how they operate.

For general wildlife in and around the North York Moors
Check out the Ryedale Natural History Society, Whitby Naturalists, Scarborough Field Naturalists, and Cleveland Naturalists Field Club for links and information. You could also follow the Whitby Naturalists and Scarborough Field Naturalists on Facebook. Also have a look at the Yorkshire Naturalists Union, who as an organisation study and record Yorkshire’s Flora and Fauna – look for their latest news, wildlife sightings, their Twitter, their Flickr Early purple orchid on a road verge near Sam's house. Copyright Sam Newton, NYMNPA.and they also have a list of the wider Yorkshire groups and societies.

For general plants in and around the North York Moors
Look out for a copy of one of the late Nan Syke’s books, such as A Picture Guide to the Wild Flowers of North East Yorkshire (now sadly out of print*) or Wild Flowers on the Edge: The Story of North Yorkshire’s Road Verges. Maybe join North East Yorkshire Botany on Facebook.

For local invertebrates
Have a look at Butterfly Conservation Yorkshire, and their publication The Butterflies of Oak Beauty Moth from Sam's home moth trap. Copyright Sam Newton, NYMNPA.Yorkshire, which brings together a huge amount of identification and ecological detail. Also consider joining the Butterflies and Moths, North and East Yorkshire Facebook page. There are around 2,500 British species of moth. I’m keen on moth trapping which allows more time for identification – the moths are released without being harmed. You can use a purpose made moth trap, or check out the BBC’s Springwatch Blog on Moth Trapping for Beginners. To find out more about dragonflies have a look at the species information and other resources on the Yorkshire Dragonfly Group website, and maybe join Yorkshire Dragonfly Group on Facebook.

For nearby birds, fungi, bats, other mammals and more
There are a multitude of other local websites and groups to follow, such as Scarborough Birders, the North East Fungi Study Group, North Yorkshire Bat Group, the Yorkshire Mammal Group – to name just four! To keep up with local biodiversity and nature news, follow Tim Burkinshaw’s Connecting For Nature Blog, and have a look at Yorkshire Coast Nature’s Blogs and News.

These are resources from around the North York Moors but if you’re from further away there will be similar local and regional naturalist groups for you too. Recording nature is something to do together for a shared purpose without actually needing to be side by side.

When you’re out and about, having a look around, always remember to stay safe during the present Covid-19 pandemic. To keep up to date with the latest National Park response to Covid-19 – see here.
