Pond Purr-fect!

Richard Baines – North Yorkshire Turtle Dove Project Officer

There is something magical about ponds: the mystery of what’s lurking in the depths, the tranquility of water and the constantly changing scene as many types of wildlife come and go on a fleeting visit or stay on to take full advantage of the precious habitats provided.

Turtle doves are no different from every other bird on the planet – they need water to survive. During the summer when our doves are raising a brood of chicks or squabs, finding water becomes even more important. Turtle doves feed crop milk to their small chicks in the nest in the first four days of their life. The milk is made from secretions from a lining in the crop. After four days the milk is mixed with regurgitated food and slowly changed to solid food as they become older.

That’s why through our Turtle Dove Project we have been keen on providing water sources – in particular now during the winter before our turtle doves return in the spring. This post celebrates one local farmer who has been keen on restoring his dew pond for a long time in the south west corner of the North York Moors and we were very pleased to assist his aim with a bit of project funding, especially as there were turtle doves recorded on the farm in 2019.

Over 100 years ago there were many dew ponds across the landscape. Originally used for livestock to drink from and created at sites which naturally collected water, many of the older ponds have now vanished as farming systems have changed and the ponds have dried up.

This is the story of the recent dew pond restoration revealed through photography…

One week later! After Storm Dennis we have water in the pond.. All we need now is the vegetation to grow back up and of course our doves to come back from Africa! 

Esk ventures

Ryan Harvey – River Esk & Coastal Streams Catchment Partnership Officer

Hi there, I’m Ryan the new Partnership Officer for the River Esk & Coastal Streams Catchment – its part of a Catchment Based Approach and my post is jointly hosted by the National Park Authority and the Yorkshire Esk Rivers Trust (YERT) . I started back in August and what a fantastic experience I’ve had so far. My role is very varied and fulfills a broad range of objectives: liaising with landowners and farmers, managing volunteers, working with partner organisations and carrying out surveys. All this effort is in the hope of benefiting the ecology of the Esk and building strong relationships and partnerships to maintain the ecology into the future.

It all started with the electro fishing season. That meant getting to know our e-fishing volunteers and arranging some refresher training for them. This was a great opportunity for me to meet the team ahead of our actual surveys and set the scene for the coming weeks. Once the work started along with volunteers I had the much appreciated help of Victoria Franklin (our Conservation Trainee) and Ami Carrick (our Ryevitalise Education & Engagement Officer). Electro fishing is a hugely important element of our data collection on the Esk. It allows us to gain a better understanding of our fish species diversity and abundance, in particular migratory species such as salmon (Salmo salar), sea trout (Salmo trutta), European eel (Anguilla anguilla) and lamprey (Lampreta planeri).

Our sites are repeated year on year and we now have a record of each species population over the last six years. This along with a whole suite of other data collecting techniques better informs our next steps and future conservation measures.

We are looking for new electro fishing volunteers for the 2020 season, so if this is something that may interest you please don’t hesitate to get in touch with our Volunteers Team. We can offer all the training you might need.

Another aspect of my role has been working alongside our Pearl Mussel Volunteers who have a long standing history in the National Park; some of its volunteers have been working with us for over 10 years. The volunteers’ work is invaluable because it’s through this group (along with contractors) that we get most of the physical works and restorations done on the river. There are usually volunteer tasks every two weeks at locations along the Esk and in surrounding riparian habitats. Tasks can vary from week to week for instance woodrush and tree planting for bank stabilization and habitat creation, riverbank fencing and repair to help water quality, as well as hedgerow and riverside grassland management to enhance biodiversity. We don’t stop for winter; this year so far we’ve tackled left over Himalayan Balsam pulling/bashing tasks on the upper Esk catchment.

Our 26 existing Riverfly Volunteers have been busy as ever in 2019, providing vital spot data on the Esk’s freshwater invertebrates. This data is crucial as many of our invertebrates are indicator species and being very sensitive they act as useful litmus for water quality and pollution. Many invertebrates are key component of freshwater and riparian food webs and many other species feed on them. Rivers need to be clean for them to thrive and in turn every other species will benefit. The data returns from 2019 have all been highly valuable for us and the national Riverfly Partnership, with most sites showing high levels of target group abundance and a few showing the highest levels in the last three years, which is encouraging news – hopefully this trend continues into 2020!

Our Adopt a Stream initiative is also a great source of data for the catchment. Another long standing citizen science project, this has volunteers who “take ownership” of given sections of the Esk, which they monitor on a month to month basis. Volunteers note down the general ecology of the site, the state of the river (flow regimes and water levels), any pollution inputs, any litter and invasive non-native species. This allows us, through the eyes of the volunteer, to recognise any apparent issues along the Esk. So if this is something you might be interested in, if you have a favourite walk or spot along the catchment you care about and like to visit frequently, then please get in touch and help us to continue to monitor the ecological health of the Esk Valley.

In addition we are hoping to start addressing some of the remaining in-river obstacles such as weirs, culverts and fords. This work could help towards the restoration of natural river processes and hydrology of the Esk and also importantly aid the passage of migratory fish species, such as salmon, trout, lamprey and eels. Structures can prevent fish species migrating up river to spawning sites and also prevent successful downstream migration of our salmon smolts which, added to the decline of salmon at sea, has further compounded population declines in the catchment in the last few decades. We found extremely low juvenile salmon numbers from our electro fishing surveys; this suggests that the installation of fish passage and fish easements could be a vital part of the continued conservation efforts along the Esk.

Lastly but most importantly there are our pearl mussels. The catalyst for all this work over the last decade and into the future is our Freshwater pearl mussel (Margaritifera margaritifera) population in the River Esk. We work with land managers as well as our volunteers and contractors to fence river corridors, plant trees/vegetation, stabilise and restore river banks in order to:

  • reduce diffuse pollution because mussels require oligotrophic (low nutrient) conditions, and
  • tackle erosion and sedimentation leading to suspended solids in the river because juvenile mussels require clean gravels with good oxygen circulation.

A strong salmonid population supports good healthy mussel numbers as the fish are crucial to the mussel’s life cycle – the larval form (glochidia) use the fish as hosts by attaching to the gills until large enough to detach and then self sustainably live within the river gravels. This is why we’re so keen on our river obstacle work because we want fish to spawn all the way up the catchment, creating strong, wide spread populations. Helping the fish helps the mussels and the mussels, being bivalves, help clean the river which in turn provides better conditions for our freshwater invertebrates, which then are fed on the by the fish and the cycle continues….

Everything in the river is connected and helping one species will help another, this is why all our conservation work is so important and why partnership and cooperation between our volunteers, land managers and partners is crucial for the future of the River Esk.

Ryevitalise Discovery: Woodlands

Ann Pease – Ryevitalise Administration Assistant

The Ryevitalise Landscape Partnership Scheme focuses on a fascinating river catchment landscape encompassing the Rivers Rye, Seph and Riccal. The area contains some truly amazing woodlands which support an enormous array of wildlife, including some real rarities.

River Rye and riparian woodland. Copyright NYMNPA.

Over the next four years Ryevitalise will focus on the conservation and restoration of woodlands and adjoining habitats such as sunny clearings and marshy grasslands, to support the wildlife that relies on these important sites.

Patience is a virtue, and what can often seem like a quiet woodland setting on first glance can be a veritable highway of activity.  Back last summer a remote, motion sensitive camera was set up in a quiet corner of woodland near Helmsley ahead of an invasive-species control task we ran to control Himalayan balsam, just to see what we could see.  The device was left in situ for two weeks, and in that time stealthily caught the comings and goings of some of our most loved British wildlife. So here are a few of the captured images of the wildlife of the Ryevitalise catchment from last summer to lighten and warm up these cold winter days.  Some are easier than others – see if you can identify the roe deer, the badger, the bat, the fox, the rabbit, the thrush feeding its chick, the roe deer, the partridge.

Spring is not too far away – but the winter itself is a particularly great time to spot wildlife in your local patch.  An influx of winter visitors such as fieldfare, wax wing, and short eared owl boost bird populations, and many animals become bolder in their search for sustenance and shelter and food hotspots can support great concentrations.  If there is a covering of snow (or mud!), head out into the countryside to find footprints and secret paths hidden during fairer weather. The Nature Calendar pages on of the National Park’s website has some great information on the types of wildlife you are likely to see throughout January and February, as well as the best places to see them.

We are always keen to see your photos of wildlife on and around the Rye area – so if you can, when you post them online please include #Ryevitalise or @northyorkmoors so we can see them too. Whatever you do this winter – take time out in nature and enjoy the best that the National Park has to offer.

STOP PRESS
The official Ryevitalise launch event will be held on 25 May 2020 at Sutton Bank National Park Centre including lots of opportunities to learn more about the habitats and wildlife of the River Rye area within that week … more details will be announced shortly!.

Going with the FLO

Victoria Franklin – Conservation Trainee

At the end of October last year it was the turn of this National Park Authority to host the National Park Authorities’ Farm Liaison Officers (FLO) Group Meeting. It was the thirtieth such meeting and we welcomed 23 farm officers from 11 National Parks with attendees from the Brecon Beacons, Exmoor, Lake District, New Forest, Northumberland, Peak District, Pembrokeshire Coast, Snowdonia, South Downs and the Yorkshire Dales.

The main purpose of these three day meetings is to enable discussions between colleagues about the common opportunities and challenges of working with landowners and land managers to conserve the special qualities of farmed landscapes. This is an annual event shared out between the 15 UK National Parks. The last time the North York Moors played host was back in 2002. There have been a lot of changes since then so we had a lot to showcase.

DAY ONE

The meeting was based at Wydale Hall near Scarborough on the southern edge of the National Park – a very peaceful and beautiful setting. Everyone arrived by midday and we started with a brief introduction and catch up from each National Park with representatives talking through their new projects and current issues from their point of view. We had a cup of tea and a presentation on the new Woodsmith Mine near Whitby followed by a drive past to see the setting within the landscape. The mine sparked much discussion around light pollution, the local economy, offsetting carbon emissions and the scale of the planned operation. We ended up in Whitby that evening for much appreciated fish and chips.

DAY TWO

Day two was all about the Ryevitalise Landscape Partnership. We started off in Nunnington, a village towards the southern end of the Rye catchment within the Howardian Hills Area of Outstanding Natural Beauty (AONB). We had roped in various members of the Ryevitalise and the Howardian Hills AONB teams to help. Paul from Ryevitalise was able to present an overview of the Landsdcape Partnership, highlighting why the National Lottery’s Heritage Fund decided to fund this 3.2 million project for the area – i.e. to enhance water quality, to improve water level management and to reconnect the people who live within the catchment with their river.

We went on for a short walk along the riverbank in Duncombe Park, Helmsley. Duncombe Park is a National Nature Reserve (NNR) because of its important ecology. We talked about the potential for alleviating some of the impacts that weirs can have on both water level management and the ability for fish to spawn throughout the length of a river.

Copyright NYMNPA.After indulging in pie and peas at Hawnby Village Hall for lunch we drove further upstream through Bilsdale to visit a farm where the farmer now has a land management agreement through the Ryevitalise programme. We looked at his riverside fields where trees will be planted through the agreement to create a riparian buffer, along with the installation of new fencing to stop stock accessing the river directly which can cause sediment to enter the water and negatively impact on the river ecology.

We ended up at Chop Gate Village Hall near the top of Bilsdale where we got to hear about riverfly monitoring from two very enthusiastic and interesting volunteers who are already actively engaged in monitoring the water quality in the Rye catchment.

Back at Wydale Hall dinner was followed by a range of after dinner presentations from invited speakers on Turtle Doves, Championing the Farmed Environment and the Esk Valley Facilitation Fund group, as well as an appreciation of Geraint Jones from Pembrokeshire Coast National Park who has been coming to these meetings from the beginning and for whom this one would be his last as he is due to retire shortly.

DAY THREE

Straight after breakfast the morning session began with a talk from Forestry England on their enclosed beaver trial ongoing in Cropton Forest.  There was fascinating video footage of how the beavers’ natural behavior of building dams can help with slowing the flow of water which has great potential as a natural and sustainable flood alleviation method.

We rounded off the session with in depth discussions of current issues including the development of the new national environmental land management scheme and rural development initiatives post Brexit and how National Park Authorities might be involved. Other subjects considered were; how National Parks could help companies offset their carbon, providing advice to farmers on how to reduce carbon emissions, opportunities for more landscape scale projects within National Parks, the always contentious issue of fencing on common land and how best to share farming stories with the general public. The meeting wrapped up at lunch time and everyone set off back to their respective National Parks hopefully with good memories of the North York Moors and its work.

It is always useful to meet up with like-minded people and discuss pertinent subjects with colleagues from other National Park Authorities. We do tend to consider ourselves to be a family of National Parks and it is great to be able to come together occasionally, to discuss ideas, to learn from each other and to return to our individual Parks refreshed and inspired by what we have seen and experienced.

The Winter King

Paul Thompson – Ryevitalise Programme Officer

Trees give us so much – visually from a landscape perspective, environmentally by cleaning the air producing oxygen and storing carbon, and emotionally as spending time in a woodland is said to boost our immune system and have a restorative effect on our mental wellbeing.  They have also had a leading role in our cultural heritage and seasonal festivals for thousands of years.

At this time of year there is one tree in particular that stands out in hedgerows and woodlands across the land – relishing the freezing temperatures, still in leaf and adorned with bright red berries, it’s the humble holly tree (Ilex aquilarium).

Image of Old Father Christmas with a holly crown and a yule log on his back. From Wikipedia.This species’ highly recognisable spiky, waxy leaves contain cells with anti-freeze properties and were historically used as winter forage for sheep, while the berries now continue to provide food and shelter for migrating fieldfares, blackbirds and thrushes. Pagan folklore has the Holly as the Winter King ruling over the cold winter months and providing food and shelter for wildlife during this crucial time, while the warmer half of the year is personified by his counterpart and adversary the Oak King; the two doing battle at the spring and autumn equinox to regain their crown. It is suggested that the origins of Father Christmas hail from the idea of the Holly King, traditionally dressed in evergreen.

The Romans gave boughs of holly to friends during the festival of Saturnalia – a celebration of Saturn and the winter solstice, later christianised to make Christmas. Christian mythology had it that holly sprang up under the footsteps of Christ, “the leaves’ spines representing the crown of thorns and the red berries the drops of his blood”. The name holly derives from “holy tree”; Jesus’ cross was said to have been made from holly wood. From medieval times holly was being used to decorate churches and people’s homes during the festival of Christmas, and it wasn’t until Victorian times that conifer trees started to take centre place thanks to Prince Albert.

In the Ryevitalise Landscape Partnership Scheme area we are lucky to have some of the largest specimens of holly in the UK.

We also have some fantastic veteran and ancient oak trees in the Ryevitalise area; indeed one of the largest collections of ancient oak trees in northern England.  These arboricultural giants are home to one of the rarest mammals in the UK, the alcathoe bat. The presence of alcathoe bat was reaffirmed by the British Trust for Ornithology (BTO) who were commissioned to carry out research into the distribution of bat populations as part of the development of the Ryevtialise scheme. The River Rye riparian corridors and adjoining hedgerows provide feeding super-highways for bat species. Ryevitalise will be expanding on this research through a citizen science project that will train up and empower the local community to monitor both the local bat and veteran tree populations to ensure they are valued and continue to thrive in our landscape.

Inspirational birds

Richard Baines – North Yorkshire Turtle Dove Project Officer

The North Yorkshire Turtle Dove Project has benefited from huge support since we started back in 2016; from local farmers to national celebrities, we have been amazed at how many people want to help the project.

This year we entered what will be our last funded year as part of our current National Lottery Heritage Fund Project. Because of this we were determined to continue the conservation effort and to keep creating habitat to help the local Turtle Dove population survive. To help resource planned future work and to generally raise awareness of Turtle Dove conservation we decided to launch an autumn of fund raising.

So – how could artists, celebrities and a couple of cyclists help Turtle Doves?

The major art theme grew out of a donation from international wildlife artist Alan Hunt who lives in North Yorkshire. Alan donated two beautiful pieces of original art to the project.

Alan’s art along with other pieces were displayed at two venues in October (Danby and Dalby) ahead of an auction of the art works. This was a big success attracting a wide range of artists from sculptors such as Jennifer Tetlow to a local poet Tiffany Francis.

Alongside the formal art auction was our unique ‘Doodle a Dove’ celebrity auction. This was run by the local Forestry England’s Funding & Development Manager Petra Young, following on from her Scribble a Squirrel project in Scotland back in the 1990s. Over 30 doodles of Turtle Doves were donated with a crazy range of images by famous people including Bill Oddie, Chris Packham, Lolo Williams, Derek Jacobi, Sophie Thompson, Derek Jacobi, Miriam Margolyes, Lily Cole and many more.

Then up popped fellow Birders Jonny Rankin (RSPB Dove Step fundraising hero) and Nick Moran (BTO) who said “How about we cycle from Thetford to Spurn and raise £3,000 for your project?”. So naturally I said a big yes please! And they did it in September, arriving at Spurn at the start of the iconic Spurn Migration Festival.

The total raised for future Turtle Dove work in North Yorkshire currently stands at £8,000. All of the funds will be spent on conservation one way or another, such as the creation of tailor made wild flower plots, pond restoration or scrub creation.

Our year was rounded off in style with news that our project had won the platinum award for the best conservation project at this year’s UK National Parks Conference. We could not have won this award without the amazing efforts of many people from survey volunteers to farmers with habitat space. We were highly commended on the international links achieved through the project such as Bird International’s Flyways Initiatives.

Traversing the Esk

Christopher Watt – River Esk Project Officer

Hi there, I’m Chris and I’ve just recently joined the National Park Authority as a River Esk Project Officer, having moved down from Scotland, and seemingly brought the weather with me! My role will involve working with farmers and landowners to implement river restoration techniques that seek to improve the water quality of the River Esk catchment.

Over the last month I have started to piece together the Esk catchment, worked with volunteers in delivering practical tasks and began undertaking fish obstacle river surveys. It has certainly been a varied introduction to the role and area.

Autumn colours in Westeredale. Copyright NYMNPA.

Volunteers braved the drizzly elements back in October to repair a broken fence on the River Esk, near Castleton. Thankfully, the task allowed us to remain on dry land and avoid venturing into the river which was rather swollen after recent heavy rainfall. A bankside tree had fallen and crushed a section of the fence-line, slackening the wire and dislodging posts. The volunteers assisted with installing new posts, including a heavy duty straining post, re-attaching the wires and finally tightening them. The volunteers worked extremely hard and it was a pleasure to meet and work with them. The task was also completed in one afternoon and the sun even came out, which is a bonus!

This task was one of the many on-going works to restore and enhance the riparian habitats of the River Esk. Maintaining riverside fences assists in keeping cattle and sheep away from the bankside vegetation and so causing sediment loading through erosion. Bankside vegetation stabilises the soil and is an important habitat in its own right. The reduction of sediment loading should help improve conditions for conservation priority species such as Atlantic salmon (Salmo salar), Sea trout (Salmo trutta) and Freshwater pearl mussel (Margaritifera margaritifera) which favour clean, fast-flowing rivers and streams.

In combination to riparian habitat enhancements, we have also been undertaking fish obstacle surveys stretching from Westerdale down  to Goathland. These involve inspecting an assortment of obstructions from weirs, fords and culverts and assessing how severe they impinge on fish migration. At each obstacle the length, width and height are recorded, along with a written assessment of the level of severity the obstacle poses to migrating fish populations.

Due to recent high rainfall, many of these obstacles have been partially or fully submerged, and although looking dramatic, have been just too dangerous to take measurements from. Electro-fishing will also accompany these surveys at a later date to inform us about fish species diversity and abundance at each obstacle. The purpose of these surveys is to update our records on obstructions across the catchment and prioritise where mitigation measures would best be targeted to benefit fish populations of the Esk. Migratory fish are a vital aspect of the biodiversity of the river.

Electrifying activities

Victoria Franklin – Conservation Trainee

Last week some National Park Volunteers (all fully trained) have finally been able to carry out the first electro fishing surveys this year along the River Esk. Delays had been caused by the weather.

The priority are sites up and downstream of the Sewage Treatment Works (STW) and one Combined Sewer Overflow (CSO) in the upper catchment. The first day of surveying was at Commondale.

The concept of electro fishing is to collect samples of fish living within the river, the higher the fish count the healthier the river should be. This will also show the type of fish living in our rivers, the cleanliness of the river and theoretically what the invertebrate population is like along that stretch of river.

The river levels had settled down by Thursday meaning the water was back to a slow flow and all the previous rain had made the water clear giving the perfect conditions for electro fishing.

We fished the river in two 50m sections, one upstream and one downstream of water treatment works. This was done using a zig zag motion to ensure that no area was left unfished. Each 50m section was fished three times to ensure a fair population of fish were caught.

The equipment used to stun the fish is called an electro fisher and consists of a positive charge the anode at the front and a negative charge called the cathode which trails along the back. These are both attached to a battery which is worn by the person conducting the fishing, today it was Volunteer Paul. Both the anode and the cathode must be in the water to cause an electro charge which is what stuns the fish, but don’t worry rubber thigh waders were worn by everyone so the electro pulse did not affect us humans like it did the fish. The rest of us were in charge of catching the stunned fish in nets alongside the anode, which is harder than it looks as the fish soon spring back to life! They are then transferred into a bucket from the nets.

We set the voltage output at 150- 200 volts which is enough to temporarily stun the fish making them easier to catch in the net. Once the section of river has been fished the data collection begins. The fish are identified – on this day we found 57 trout downstream and 104 upstream with the largest being 180mm and the smallest recorded at 52mm. The information collected will now be analysed before being sent onto Yorkshire Water, they will then compare this with the other locations which are due to be fished over the next few weeks, and that will all help inform management of their sites as necessary.

An amazing day was had by all the volunteers and staff that attended. More data collection will happen in the next few weeks on different sites along the Esk.

Much Ado About Mothing

Sam Newton – Land of Iron Natural Heritage Officer

MOTH NIGHT

Records generated from moth trapping with light traps by amateurs naturalists all over the UK is the main way conservationists can understand how moth numbers are changing. N.B. The moths are subsequently released unharmed. While many enthusiasts moth trap year round, Moth Night is an annual celebration of moth recording throughout Britain and Ireland aimed at raising awareness of moths among the general public. It is organised by Atropos, Butterfly Conservation and the Centre for Ecology & Hydrology. Usually held in the summer months, this year it is being held from 26-28 September to target the spectacular (in appearance and in name) Clifden Nonpareil, and other late summer migrants moths.

The records generated from Moth Night, and from all other moth trapping is useful to conservation. While declines in large and ‘charismatic’ species are regularly reported in mainstream media, insects are often forgotten. For example in the UK, Butterfly Conservation reported habitat specialist butterflies (26 species) to have declined by 77% since monitoring was started in 1976, while more generalist butterflies (24 species) decreased by 46%. This is unfortunately also seen on a global scale, with 40% of insect species declining, and a third classified as endangered. It’s also not just the numbers, but the biomass, with the total mass of insects falling by 2.5% a year – suggesting an unsustainable future for populations.

The more we know about insects, the more we can do to try and save them. Below are a few images of moths recently seen within and around the North York Moors, including our own brilliant Clifden Nonpareil – the first time this moth has been seen in Yorkshire for many years.

In the Zone

Aside

The North Yorkshire Turtle Dove Project area is now considered a Turtle Dove Friendly Zone. These zones form a loose association of areas in England where Operation Turtle Dove is in action. Here’s a link to a recent Operation Turtle Dove blog post with a bit more info on what’s going on across the different zones including ours.
