Talking about trees

We continue our series of interviews by Lucy Johnson, in which she interviews some of the key players in the development past, present and future, of The Aire Rivers Trust. We thank her for her commitment and expertise in putting these pieces together.

This month she interviews Roger Parkinson in preparation for National Tree week (22-30 November 2025)


At the beginning of August I sat down with Roger Parkinson, who has a wealth of experience volunteering with nature-related charities, in particular focusing on trees. Roger currently leads local education sessions for the Woodland Trust and has previously worked with the RSPB locally, in addition to undertaking many projects in his local area.

We spoke about how trees can form part of shaping different landscapes across the country, and Roger commented that although sycamore may not be the right tree for every situation, when millions of trees can be lost to a single storm, it has a part to play in recovering tree numbers. The Wakefield district in the 1980s had under 4% of tree cover, which is now a healthier 14%. Sycamore is playing its part in that and in taking carbon from the atmosphere, although it wouldn’t be selected for planting.

Aside from his interest in nature, Roger also enjoys motorbikes, having been a motorcyclist for over half a century. However it is trees which have formed the spine of his volunteering commitments. “I’m still fascinated by it,” he commented. He hopes to pass this on to local children, “How does a tree know to wrap its seed in a fruit, that a creature which it can’t see is going to come and collect it, then eat the fruit and then drop the seed somewhere else?”

Roger stood in front of a tree

Roger began planting acorns and growing whips 37 years ago, to show to his son how they grew. Combined with living near many former industrial sites near Wakefield, which had been used as landfills and capped off, with the support of the council, the family began efforts to improve the regeneration of these areas. Over a period of years, Roger built up relationships with Wakefield Council’s tree officers, who were tasked with managing the countryside sites as well as forestry tasks.

This led over time to the creation of the arboretum at Newmillerdam, a beautiful site which is free to visit year round. The group was initially refused National Lottery funding, which Roger sees as potentially a blessing, as it led to them exploring alternate angles to fund their diverse collection of trees. Some are planted as memorial trees, whilst others are funded by members of the public who enjoy the area and want to make a donation towards the paths or bird boxes, for example. The trees within the arboretum all have individual signs detailing their species, meaning that people can visit and choose species for their own gardens, causing an increase in visitor numbers. 

In planting on disused industrials sites, trees planted in Roger’s son’s boyhood now tower over the landscape. Roger also used his industry expertise to suggest using trees to reduce the effects of rain that was soaking through household waste and emerging as polluted water. Roger terms this as, “using trees as a piece of civil engineering,” and also evidences his belief in improving areas that others might be quick to write off. Around 13,000 trees were planted there, some by local primary school children, to slow the run-off. The trees are unlikely to grow to their full potential, but they will adapt to the site and do the best they can. Tolerant native species such as oaks and hawthorn were specially selected for this site. Kestrels and kingfishers have also returned to some sites.

Each small success buoys Roger on: “that’s what motivates me because I can see that we can make a difference, you know, we can change things in a positive way.” Part of that is making himself available to advise on hedgerows or orchards, for example, in addition to providing support on where to buy trees and how to get permissions. Roger firmly believes in selecting the right tree for the right places, and that all trees bring benefits for people and wildlife whether native or non-native. One of Roger’s projects is to give away thousands of trees each winter, funded through various sources. This is usually timed for the Tree Council’s National Tree Week in November.

Discussing a tree in a forest with a group of people

Roger’s mother was brought up on a farm in North Yorkshire, then moved to Barnsley on getting married, which was a huge contrast for her. Roger attributes his interest in nature to hearing stories about her experiences. His father was also aware of the benefits of getting out in the countryside, being a keen walker. Roger theorises that having been in the second world war, his father was able to find peace in the countryside. In the countryside around Barnsley, Roger comments, “Within 20 minutes you could be in some lovely countryside with magnificent trees in hedgerows.” Roger can still remember some national campaigns half a century later, in particular, the campaign by the newly-formed Tree Council, Plant a Tree in 1973, which was a response to the loss of elm trees.

In his family life, recycling and care of the environment has always been a priority for Roger, from the early eighties onwards. He encouraged his young son when he showed an interest in acorns, making makeshift planting containers to show his son the process of growing. The result of this early exposure was that his son studied for a degree in ecology and now manages woodland restoration for the Scottish Forestry.

After winding up his career in civil engineering, Roger travelled around the world with his family, then began working with the RSPB on nature reserves, primarily with education. He was enthusiastic about the return of the St Aiden’s site to nature, praising its transformation into the home of bitterns, amongst other wildlife.

Roger commented that Fairburn Ings, having once been the largest spoil heap in Europe, used to be “a grey scar on the landscape.” Having seen its transformation over the course of his lifetime, he said, “that gives me hope that we can change things.” He identifies networking as a key source of change, “working with lots of different bodies, government bodies, groups, organisations, whether they be charities or community groups.”

Sixteen years ago, Roger saw an advertisement for volunteering for the Woodland Trust as a volunteer speaker, which he was already doing at Fairburn Ings. He quickly adapted the provided off-the-peg talk to his audiences, to better convey what was happening at locations relevant to them. He wanted also to make audiences aware of the positive initiatives in their local area and ways that people could get involved. This often also led to groups organising walks at the locations mentioned.

For Roger, volunteering is a force for good, allowing people to contribute in positive ways. “I’m a great believer that we all must have a purpose in what we do in our lives.” In Roger’s opinion, lack of purpose can exacerbate depression and other issues. He credits the Rivers Trust movement and other charities with giving many people the opportunity to improve their own circumstances.

Threaded through Roger’s tree projects has been a commitment to the use of trees not only as enhancing natural spaces but to achieve civil engineering goals. He sees trees as being of vital importance in creating corridors to connect nature, whether by rivers, canals or even highways. Even as areas are regenerated and rebuilt, trees can be included to help with infrastructure and increasing the area covered by trees. Alongside that it is vital to ensure that people are aware of the benefits of trees, such as keeping temperatures cool, and not merely the minor inconveniences of maintaining them.

Although not formally trained in civil engineering, Roger ended up working with civil engineers by happenstance doing a variety of tasks, experience he has clearly used to great effect. Part of his former company’s philosophy was to use environmental managers to improve areas when jobs were complete. As the company worked on a variety of sites for a variety of stakeholders, this gave Roger valuable insight into designing and managing sites.

Roger has seen approximately a ten-fold increase in demand for his Woodland Trust tree talks following COVID. He attributes this to an increase in people discovering firsthand the benefits of time in natural spaces. Within this he sees an opportunity to educate people and give them a tangible way to contribute to improve their local spaces, which may otherwise not be available to them.

Roger doesn’t have a favourite woodland per se, but imaginatively, he sees older woodlands as a form of time travel. He commented that further south, “You can be walking through a woodland and you’ll come across an old tree that might have been there hundreds of years. When I look at a tree like that you think, my God, if that tree could talk, the things it’s seen walking down this path. That tree’s had a life and there’s a story to tell. It’s still alive, it’s hanging on, it’s hollow now, because that’s part of its cycle. What a characterful thing, to see that.”

Roger did have an answer for my pet question about folklore. He chose the Green Man, seeing him as a representation of humans’ connection with nature. We went on to talk about my new habit of assigning trees a gender, and Roger was open in embracing all ways of relating to trees and nature, commenting, “Just enjoy the space and for whatever reason you’re there, just absorb your surroundings.”

Roger with a bag of tree saplings to give away

If you are interested in the tree giveaway, Roger and other volunteers will be at Thornes Park Nursery in Wakefield WF2 8QE every Sunday from 23rd November 10am to 12pm. A variety of native trees are available. Please text Roger on 07973 421146 for further details.

Olivia Holmes

We continue our series of interviews by Lucy Johnson, in which she interviews some of the key players in the development past, present and future, of The Aire Rivers Trust. We thank her for her commitment and expertise in putting these pieces together.

Olivia Holmes

Olivia is decidedly unflamboyant and undemonstrative, but also patient, unflappable, resilient, measured, knowledgeable and supportive. She gives the distinct impression of being able to rise to any challenge handed to her. Olivia joined the Trust as Project Assistant in July 2023, and has recently taken on the role of Project Officer (subsequent to this interview taking place) after the departure of Gareth Muir. In speaking of the opportunities the Project Assistant role has given her, she was extremely positive. “I’ve loved the variety of stuff that we’ve done. We do different things every season and pretty much nearly every week. You can’t really get bored in the role.”


Olivia was also positive about her workmates. “It’s such a nice team to work with, so supportive. They care a lot about my development. They’ve been encouraging. Even if I have doubts about my own abilities.” Olivia singled Gareth out for praise in particular, stating, “he’s been a very good teacher, supported me with development and he’s not coddled me.” ART’s Senior Project Officer Nick Milsom has also played a major role in Olivia’s development.

Olivia was full of praise for volunteers, commenting that she enjoyed interacting with people of varying backgrounds and life experience, which informs their approach to tasks. She noted, “One of my favourite things is working with volunteers, building up nice relationships with interesting people who’ve lived lives that I want to hear about and then also doing meaningful work in a place that I care about.” She also commented that apart from the obvious benefits of participation, it has occurred that corporate volunteers have managed to initiate business deals after meeting on volunteer days.

Olivia comes from a large family, being one of five, and has always been active and outdoorsy. She remembers childhood walks in nature fondly, where her parents drew on their science and history knowledge to make the walks interesting. The Malham Tarn walk is a particular favourite of Olivia’s, although she states, “I also feel very linked to pine woodland dune walks that we do in Dorset, specifically on Brownsea Island near Bournemouth.” Olivia attributes her interest in using questions to draw out further knowledge to these walks.  “I like to find out things about people, about places, things. Walking along, always pointing stuff out and wondering what they are, why they’re there and what they’re doing.” A useful approach for a Project Officer!

In addition to the practical conservation skills developed alongside Gareth, other staff and the volunteers, Olivia also has an impressive academic background, taking part in a substantive research project in her placement year, examining the protocols used by ex situ seed banks around collecting seeds, for which she will occasionally speak at professional meetings. This can be viewed here https://www.kew.org/wakehurst/whats-at-wakehurst/millennium-seed-bank

Prior to working for the Aire Rivers Trust, Olivia worked on bat surveys, enjoying working at night and talking to landowners. She has also worked in cafes and spent a year volunteering with the Yorkshire Dales National Park Upskill Downdale scheme, which is aimed at young people in the Dales. It was a “full circle” moment for Olivia when the next year’s cohort were able to come along to an ART organised day. The group worked to remove Himalayan balsam at Trench Meadows, an SSSI located near Saltaire. Long term, Olivia would like an educational role or potentially to work with farmers in environmental land management. A return to academia does not appeal due to the pressures of deadline structures.

In her free time, Olivia is a highly trained dancer and a skilled sewer, most recently creating a beautiful orchid-coloured silk dress (for which a formal occasion is required, if anyone would like to organise a gala dinner). The next project will be a lined denim shirt.

Olivia emphasised the seasonality of her work, and how much she enjoys experiencing the seasons change. When asked if she had a favourite bit of folklore, she picked an Irish tradition threaded through the 2025 Lia Leendertz Almanac, the interplay of St Bridget with the Cailleach, the one representing spring and summer, the other representing autumn and winter. She appreciates the interplay between the two, and is grateful to live somewhere that actually experiences distinct seasons. Her link to seasons extends to having a dedicated playlist for summer. “I live my life a lot around nature, especially in the work I do.”

Rachel, our new Chief Executive

We continue our series of interviews by Lucy Johnson, in which she interviews some of the key players in the development past, present and future, of The Aire Rivers Trust. We thank her for her committment and expertise in putting these pieces together.


Headshot of Rachel Forsyth

Arriving early for our scheduled interview (I have a healthy mistrust of scheduled bus times), I found the Aire Rivers Trust’s new Chief Executive Rachel Forsyth tucking into her lunch in the midst of the rest of the staff, swapping stories and jokes. I had already met Rachel on her official first day, when she came across as down to earth, knowledgeable and approachable, but I wasn’t expecting such a warm, communal atmosphere. Geoff, current trustee and former chair of ART, commented that Rachel stood out from other applicants because of her “vision.” He credited her with the ability to “see where we need to go” and “not get sidetracked,” but this comes with a big helping of playfulness.

We settled in with our drinks in the communal kitchen and picked up where we left off. Rachel is a law graduate who has spent most of her career working with the National Trust in varying roles, initially in more on the ground roles, but most recently working as Countryside Manager in the Yorkshire Dales, managing a team of rangers and an ecologist and determining long-term plans for the land. Within this Rachel looked at everything from soil and water health to public access and heritage. Throughout each role, learning and developing was important to Rachel, and this knowledge will be used for everything from delivering huge projects to having the edge on pub quizzes.

Like Geoff, Rachel has had a close connection to the outdoors and nature since childhood, spending a lot of time in the garden as a child. There were no early ambitions to work in nature, in fact the opposite as she was very intrigued by the idea of racing cars, but the experience of studying law reoriented her back towards her early interest. Her childhood, initially in Kent then in Northampton, sounds idyllic, with family walks and outings as a family to watch a nearby badger family in their large sett. She also remembers seeing hedgehogs and dormice in the garden, in addition to watching birds on the North Norfolk coast and whale watching trips. Rachel added, “It wasn’t like that all the time,” but clearly it was enough of the time to spark a lifelong interest and satisfying career.

Alongside her keen interest in knowing details and facts to get just a smidgen more points than her peers in quizzes, Rachel has a knowledge of and interest in management theories across diverse sectors, citing several during the interview. These were mostly focused on helping team members achieve their best, which is something Rachel has thought about in detail and drawn upon ideas from fields such as technology to hone her own perspective. We discussed the idea of creating multiple ideas, most of which will not be acted upon, but which can lead to a greater diversity of solutions and a better utilisation of staff skills.

Rachel is still in the early stages of her role. I asked her if she had any changes she had in mind, and she clarified that initially she wants to focus on “listening,” and finding out what’s currently in place. She also commented that some things may alter, but they may well be led by what the rest of the team have identified as possible to improve. Throughout the interview Rachel was quick to praise the support she has received from the trustees, particularly Wendy the chair, and Geoff, all staff members and her predecessor Simon, who she credited with managing a very high workload very effectively.

Rachel defined the Chief Executive role as providing a key link between the trustees and the staff, alongside taking a role in high-level partnerships and overseeing the future direction of the charity. Current partnerships are with Yorkshire Water and the newly formed regional group across Yorkshire, of the Don Catchment Rivers Trust, the Calder and Colne Rivers Trust, the Yorkshire Dales Rivers Trust, the East Yorkshire Rivers Trust and of course the Aire Rivers Trust. Rachel will be co-leading one of the group’s work-streams on community and volunteering.

Meeting with the other local rivers trusts has sparked some reflection about the structure of the charity, as each trust has their own individual set-up and set of expertise. One trust has a geomorphologist and a farm adviser, but they don’t benefit from administration support. Equally, as charities grow more specialised roles emerge such as dedicated fundraisers, but this also means more team members who are not directly engaged with the core aims of the charity.

Finally, we spoke about what wisdom might be contained in folklore relating to the natural world. Rachel pointed to people’s personal connections to woodlands as a way of connecting to the past, and said that the reaction to the felling of the tree at Sycamore Gap showed the depth of connection that people feel which they aren’t always aware of. Pragmatically, she picked the example of planting rowan trees by your front door to ward off evil as not necessarily true, but emblematic of a broader relationship between planting trees and good things resulting. Let’s hope good things result from Rachel’s new role and the Trust’s current tree planting and other projects.

Geoff Roberts

This is the first in a series of interviews by Lucy Johnson, in which she interviews some of the key players in the development past, present and future, of The Aire Rivers Trust. We thank her for her committment and expertise in putting these pieces together.

            Before Christmas I sat down with Geoff, a former Chair of the Aire Rivers Trust and current trustee, to talk about what led him to become involved with the charity and to discuss some of his aspirations for the future including partnerships with other Rivers Trusts and Yorkshire Water. Our conversation took place on a gloomy day in December, in a small room furnished with vending machines just behind the post room at the ART HQ.

            Geoff is tall, bluff, direct and straightforward, with a warm manner. He comes across as very grounded in practical matters, so I was surprised at the almost whimsical nature of the quote he chose when I asked him for a favourite piece of wisdom. He plumped for the famous quote from the 1989 film, Field of Dreams, “build it and they will come,” which he interprets and puts into practice as, “create opportunities for people who will take those opportunities.” This has been a focus for Geoff since winding down his second career as a consultant on organisational change post several decades with Yorkshire Water, within his work with ART and a recent new trustee role with the Bradford-based Participate Projects.

            Geoff characterises the River Aire as the “life-blood” of the community, and has worked for many years to enhance that. He has also been able to bring the environmental focus into play in his role at Participate Projects, using his expertise to guide young people as part of the Venturists programme.

A theme that emerged through our conversation was the importance of the exposure to nature in childhood. Geoff himself during his childhood in Hull would frequently go fishing with his father. He credits these trips with giving him exposure and knowledge that was definitely not part of his schooling, commenting, “you didn’t talk about the environment. No one was worried about it.” Geoff was also influenced by the author Henry Williamson and his books, “Tarka the Otter,” and “Salar the Salmon,” both titles coming readily to mind. Building on this personal experience, Geoff states, “If we can work with children and get children to value the environment and to value water in particular, they will become advocates for life.” Education and engagement are part of the Trust’s key strategies.

            We also spoke about ART’s early days. We’re getting into third-hand information here as Geoff was not on the roster till 2013, but it seems that Kevin Sunderland called a meeting a couple of years prior to that, identifying the need for action to improve the River Aire, and a small charity was formed in 2012 comprising some trustees including current chair, Wendy. With typical understatement, when Geoff heard about ART, he contacted them saying, “I know a bit about the Aire.” He has been putting his knowledge to good use on ART’s behalf since, notching up hundreds of hours.

Geoff was asked to become Chair a couple of years after joining. He remained as Chair for seven or eight years, during which time the annual turnover of the Aire Rivers Trust increased tenfold, mainly thanks to the DNAire project. This project was based around getting salmon up to Skipton, and creating fish passes at four significant weirs.

Throughout the interview Geoff emphasised the importance of working in partnership with other organisations, and commented that in his own career he saw a shift from technical skills to relying more on people skills to move forwards. Sam Riley-Gunn leads the ART citizen science projects, and with his professional background Geoff is able to advocate for the use of data gathered to supplement the knowledge base of organisations such as Yorkshire Water.

Recently, in addition to supporting Wendy, Geoff has been instrumental in bringing about a regional partnership with Yorkshire Water between the Aire Rivers Trust and four other Yorkshire rivers trusts – the Yorkshire Dales Rivers Trust, East Yorkshire Rivers Trust, Calder and Colne Rivers Trust and the Don Catchment Rivers Trust. As a group, there will be opportunities to learn and develop, and perhaps to have more of a voice at a broader level.

Geoff’s journey from being a young boy with an impressive chemistry set, to working within analytical chemistry at a firm which was itself polluting, and from there to Bradford to work for many decades with Yorkshire Water working with pollution at all levels, is one that has made him invaluable to the Aire Rivers Trust and to the broader community and given him irreplaceable knowledge and experience.

Extended Riverfly Monitoring

Extended Riverfly with the Don Catchment Rivers Trust River Went Project

The usual hazard I encounter getting to river volunteer event days is sleeping through my alarm clock. This Friday I had a legitimate extra hour in bed courtesy of the Don Catchment Rivers Trust, who had organised an event close to me. However, my pleasant walk to the site, a favourite walk for me, was held up by a large cow making strategic use of a necessary gate as a scratching post. I tried five minutes of gentle cajoling, before deciding to risk being crushed and squeezing past.

The event was an introduction to Riverfly Extended Sampling. The site chosen, championed by Hiram and Jason, was the intriguing location of before and after run-off from the A1. There is an iconic viaduct, built in the 1960s, which brings a gentle roar to the valley, which houses attractive villages and the beautiful unspoiled Brockadale woodland. Also in attendance were Sally and Rebecca from DCRT, Dave and Sue who river monitor locally, and the ‘Knowledge Man,’ who was indispensable over the course of the day, Sheffield-based Paul. Throughout the day Paul frequently identified several species at once, and wryly commented to me when I announced that I thought I had a tray, “with nothing in it,” that “there’s a sleeve in it.” As with all of his pronouncements over the day, this was duly proven to be correct.

My walk to the event, much more direct than the route by car, followed the river Went the whole way. Whilst I have a sentimental attachment to this river, my dad having played in it in the sixties, and some of the locations are beautiful, let’s not pretend it’s teeming with life to the fullest extent. I walked past the large sewage treatment centre a mile and a half upstream of the sampling site, which discharges so frequently that it is rumoured phosphates are going to be removed first in a facility upgrade.

Why is an extended riverfly necessary? It runs alongside the regular ARMI count and is cross-compatible, although the stone search is slightly shorter, replaced by a surface sweep. It is designed to give a more detailed picture of the character of a river. After numbers are inputted into a bespoke spreadsheet, the output is a Water Quality score and a Silt and Flow score. It is a new scheme, developed from two pilot schemes in Dorset and Lincolnshire. Unlike the regular riverfly, there are not currently trigger levels. Typically, this type of survey would be completed two to four times a year.

Riverfly monitoring equipment

When I arrived, three tables were set up in the shelter of the viaduct, one laden with coffee and treats, one set up with traditional “party food” trays placed on laminated A2 labelled sheets, and the third with a more compact and orderly labelled trays with compartments of the type you might keep beads or nuts and bolts in, with some leaflets and books. I’m afraid I didn’t refer much to the printed matter, preferring instead to defer to Paul and Sally’s knowledge. There were also sturdy long-lived Soviet-era microscopes inherited from the University of Sheffield, which revealed surprising details and colour in our invertebrates, an ample supply of plastic spoons (for sorting insects, although Dave and Sue came armed with long-handled paint-brushes, a tip new to me), and small-handheld lenses, in addition to a fair amount of river-water confidently dispensed by Sally at one point as she tried to pour some of the sample through a tiny net.

After an explanation of the survey we proceeded to our first sample. The underlays to the trays were beautifully designed. Sally had done an amazing job using colour and type of species to delineate them. We gravitated towards the table with the octagonal trays for the most part. I did make a token effort to use the bead-box system, but for me at least the larger layout was far more intuitive and educational. In practice the more compact version is probably far more viable in the field, but for accessibility, ease and enjoyment I’d plump for the space-consuming way.

Our first sample had everything from bivalves to olives, and plenty of them. We spent about 90 minutes sorting through the weeds, leaves and vegetation, rescuing the occasional fish, then completed the first survey form. The form is straightforward and is cleverly designed to make obtaining the standard ARMI numbers very clear.

 I didn’t find it intimidating or overwhelming. For some reason I was able to spot incredibly tiny invertebrates comfortably – I often struggle with doing things involving very fine motor control such as embroidery, but in the context of shuffling little invertebrates around outdoors with other people this was fine. Many of the additional species were immediately obvious, such as leeches and hoglice, and those that weren’t became more familiar over the day, such as blackfly larvae. I remain incompetent at distinguishing blue-winged olives from regular olives, as of the several species of mayfly covered only olives had received the invitation.

After a delicious lunch thoughtfully provided by Hiram from legendary local bakery Hinitts, I helped Sally as timing buddy and spotter for the second location downstream. My favourite spot in Brockadale is the wall of Hart’s Tongue fern, and our second sampling location was right there, approached from the south bank after squeezing through a gate. I’m not sure how Sally got the bucket through, I was too busy wiggling and hoping I wouldn’t get stuck. There were significantly less reeds at the second location, but we made do, Sally performing the surface skimming which is added to this sampling type with confidence. With the light and people’s energy fading, we analysed the second sample, which was less abundant, particularly in gammarus, but very rich on minute bivalves, which were challenging to count.

The day was extremely well-organised and we were lucky with the weather. As for the sampling itself, obtaining the sample is mostly the same, and analysing it is not too taxing. I’m still at the happy to be able to identify a cased caddis stage, never mind whether they have hoods, bush-tails, or weighted cases, but I will know to look more closely the next time I see one.

If you have tried the standard riverfly and not enjoyed it, Extended probably won’t change your mind, but I would recommend trying out Extended to anyone who does river sampling, to bring a little more context to regular sampling. The final scores were Site 1, an ARMI score of 7, Water Quality 28, and Silt and Flow 32, Site 2, ARMI score of 5, Water Quality 21, and Silt and Flow 26.

I’m disappointed that the River Went, through unspoiled woodland, couldn’t muster better ARMI scores than I get with monitoring with the Calder and Colne Rivers Trust, on my blue-tinged stretch of Spen Beck. I guess that’s what you get when you channel run-off from a dual carriageway into a watercourse, which is itself already essentially an outfall for a large village by the time it reaches Wentbridge. Sally and Paul were optimistic that the phosphates measure will improve matters.

Please contact Sam Riley-Gunn at contact@aireriverstrust.org.uk if you are interested in monitoring with the Aire Rivers Trust next season, or if you would like to hear more about other river-related events.

Sally of DCRT can be contacted at info@dcrt.org.uk or www.dcrt.org.uk if you are in the catchment area for the River Don and would like to know more about standard or extended riverfly or practical days.

Be safe near water

Hardly surprising that much of our work is in or near water, so this blog from Lucy Johnson, one of our volunteers, is very timely.

Clambering carefully up the wooden steps in the old boat house, we find a cosy space, brightly lit. A half circle of chairs surrounds Dave of the Northallerton-based River Mountain Experience, ready to deliver another insightful session on water safety. Dave delights in defying expectations, in presenting a fact then placing it in context, or conversely, turning it on its head. His enthusiasm and evident expertise in his subject comes across clearly, lighteningsome of the somewhat sobering facts he covers.

The upstairs room is peaceful, as occasional pairs of rowers glide by, visible from the balcony. The floorboards are worn, and staircases lead off in all directions. Bright sunshine comes in through the skylights angled in the wooden roof. On the walls are photographs of various rowing teams going back through time, framed newspaper articles, and a large-scale river map with hand-marked additions. Dotted around the room are loud-hailers, indeterminate plastic boxes and a covered pool table. There is also an A frame stand, which turns out to be Dave’s, not part of the general fixtures and fittings.

Dave runs over some of the key facts related to drowning in the UK, and highlights that traditional Health and Safety regulations target fixed not dynamic situations such as water environments. We created a lengthy list of specific water environments and hazards we might encounter, with everything from livestock to World War 2 ordinance. Next we assessed a series of photographs showing a range of water environments, including weirs, tidal rivers and becks covered in vegetation.

We discussed the drawbacks of using PPE, and the importance of staying alert to weather conditions. Different hydrology features were discussed, some of which can easily catch the unwary out, such as the rolling movement at the bottom of weirs.

Next was an equipment run-down, split into things that keep you dry and things that keep you afloat. Waders can actually cause accidents as they will fill with air if you slip. We looked at life jackets and buoyancy aids (the difference is in the amount of buoyancy they provide) and tried various models on. We also checked the internal workings and discussed the various ways in which they operate.

Cold water immersion is a key factor in water safety in the UK, as the water temperature is often below 17°C. Different factors affect the onset of hypothermia but it is a real risk. The fire service is responsible for river rescues, but access points may not always be ideal. Be prepared to provide as much location information as possible, such as postcode, grid coordinates and a what3words location.

The final part of the course was spent outside in warm sunshine reliving school sports days. We lined up one by one to carefully throw a tow-line using the correct technique to a hand-made, red-painted wooden casualty, who obligingly had his arms up in the best position to receive the rope. This is a skill worth having; take up the chance to practise on a practical volunteer day with one of the Trust’s tow-lines.

Which tree is which?

One of our volunteers, Lucy Johnson, writes about trees.  

If you want to learn how to identify trees in winter when many of the most obvious clues are absent, you could do worse than buy a copy of John Poland’s “The Field Key to Winter Twigs,” published by the Botanical Society of Britain and Ireland. Alternatively, you could volunteer with the Aire Rivers Trust in the winter months and pay attention to detail, or give yourself a helping hand by attending Sheffield General Cemetery’s excellent tree identification event, intended to be held annually each January.

A Miniature Quest

As a regular Aire Rivers Trust volunteer who is not particularly observant, I went to Sheffield to learn more about the species we have been planting and to sneak a peek at the beautiful deconsecrated Victorian cemetery. I wanted to increase my ability to identify “whips,” the very young trees carefully planted by the Aire Rivers Trust in the winter months. Not just any old whip will do – the ones selected by ART are chosen to bear in mind their nativeness, their ability to coexist with water, how susceptible they are to climate change and sometimes how appetising deer find them. I was envious of the project coordinators’ and other volunteers’ ability to identify the whips at a glance, with a surety and ease that eluded me. With many phenomena, knowing how it’s done or knowing more about the topic can take away its simple enjoyment; let’s see if that would be the case for me.

A Picturesque Setting

Navigating to the cemetery was pretty easy – I headed out of the city centre and soon found a steep road heading up a hill signposted “Cemetery Road.” Reasoning that I was likely in the right place, I ended up in an oasis of calm, surrounded by lovely, currently unidentifiable to me, old trees and picturesque gravestones. There was a sense of peace in the setting, enhanced by the occasional strolling dog walker. Sally and a team of dedicated volunteers manage the cemetery.

Three Experts in One Day

I quickly found my way to the Samuel Worth Chapel, where I was greeted by one of the day’s experts, Gerry, who has spent many years researching plants and is currently working on a monograph about the plants in the cemetery. Ushered inside to the warm, I was given a handout detailing eighteen types of trees; all merged into one to my untutored eyes. I chatted with Sally and Claire, who were highly knowledgeable about trees and birds, respectively. Sally’s interest in trees developed following her employment at the cemetery, whereas Claire has had an interest in birds since childhood, thanks to her father.

Out Into The Cold

The tour began with the languorously beautiful weeping ash pair that framed the chapel. These trees were planted to enhance the chapel’s design, which they have faithfully done for over a century. They are nearing the end of their life span. Fierce debates are underway as to which is the most suitable replacement for the good of the cemetery in years to come and to form a backdrop for weddings. During 75 minutes we saw everything from Turkey oak to Oriental planes, via ash, elm, elder and everything in between. Claire also identified the sounds of several less common birds for us.

A Little Bit Muddy

We were invited to step off the path at various points to get in the slightly squelchy ground among the trees – this was not a pickled-in aspic tour led from behind wire fences. While Sally ably led the tour and provided details on identifying key features, whether bark or bud position, Gerry provided a broader context and history. Of course, this being a graveyard, there was a glorious yew, which we were gently reminded was wholly toxic to humans.

A Final Test

Dodging squirrels and the occasional runner, we returned to the chapel for the dreaded test. We were encouraged to handle the long stems numbered on the table, representing 12 key species, all covered during the talk. I confidently identified yew, horse chestnut, hazel and hawthorn, and then my attention span maxed out after about seven guesses, leaving five remaining unidentified. Sally patiently guided me through the remaining five.

Some Wizardry Here

Are any Harry Potter fans reading? Does anyone recall the moment in the first book where Ollivander the wand-maker, says something to the effect of, “The wand chooses the wizard.” I got to experience something similar when Sally placed one particular branch in my hand – it felt so wholly right, and I am sure it would form my wand in a Harry Potter existence. Indeed, I think it does form the wand for at least one character. I shall re-read the whole series from a tree-lore perspective and report back.

Did 75 Minutes of Tree Talk Work?

A week later, waiting at the bus stop, I looked up, noting that the tall, bare trees marching down the road and clustered opposite were still a mystery to me. Then my eye fell on some unmistakable buds – horse chestnut. Conker cases still litter the ground. I am very familiar with this tree, but now I can decode its bare branches without needing to look down or to have seen the tree in summer. I may not be able to tell my rowan from my field maple yet, but my knowledge and confidence have improved. The trees have lost none of their beauty, for knowing a little more about them.

An Outfall Safari at Oddfellows

One of our volunteers, Lucy Johnson, recently took part in the training for our Outfall Safaris. Outfall Safaris are walks along the river by volunteers looking for pipes, or outfalls, from which water is spilling from in dry weather. Most of these spills are the result of misconnections where homes and businesses have been connected to underground waterways rather than the sewer. Throughout October and November, Lucy and the other volunteers from the Aire Rivers Trust will be recording these, and the impact of licensed sewer overflows, to urge Yorkshire Water and others to take action to improve them.  

In the article below Lucy reflects on her experience and hopes for the project.

Last Saturday I traipsed out of the house with a selection of pens, a notebook, delicious sandwiches and footwear suitable for any condition from completely dry to slight rainfall in a paved area. On the train from Leeds, I struck up a conversation with another compatriot from my part of West Yorkshire, also venturing out west of Leeds to enjoy a walk from Crossflatts to Ilkley for the first time since COVID. Having properly set the world to rights before the day had really begun, I speed-walked my way through Skipton to my destination. Unfortunately, my outing was not to explore the countryside at Skipton (nor my favourite cafés) but to attend training, not something I generally feel well disposed to on a glorious Saturday.

How to spot sewage

The training was the final of four recently organised across the Aire Valley by Sam Riley-Gunn of the Aire Rivers Trust, to empower citizens to take action on polluting outfalls in their local rivers and becks, and was successfully crowd-funded. Within the umbrella of the Rivers Trust, many of its member organisations across Britain and Ireland have adopted the model originated by the Zoological Society of London to record and respond to polluting overflows.

In Oddfellows most people (presumably having had more reliable modes of transport than two early morning Northern trains) were settled and ready to go, provided with a feedback card, a brightly-coloured white-board marker, and a tricky-to-prise open oversized plastic lanyard containing key reference information, and a hot drink. We cracked straight on. Over the course of the day, we learned about everything from the history of sewers to the inside story of how to get Yorkshire Water to cough up a £1,600,750 fine, to the finer details of Whatsapp features and a tailor-made form including photographs, descriptions and other monitoring details.

A Legendary Pollution Hunter

Rob Hellawell is a veteran of the delicate dance of reporting water pollution to the Environment Agency and Yorkshire Water, primarily in the area around Bradford. Some reports can take years to come to fruition. Rob was instrumental in helping the Environment Agency prosecute Yorkshire Water in Bradford years after the pollution took place, thanks to his careful documentation. He recommends arming yourself with the key phrase, “I’d like to report an incident of pollution to the water course,” in order to get connected to the right phone operative. Provide photographs, report immediately if you witnessed it first-hand, document the location using what3words (be prepared to spell the words out to avoid confusion), and wangle a no longer provided standard reference number out of them for follow-up, which of course as a newly-minted intrepid pollution hunter you will do.

Safely as you go

There were some safety considerations to bear in mind. Be careful to cover open cuts on your hands, use the antibacterial gel provided after contact with the river, don’t wade above ankle depth and be aware that flash-flooding can occur. The energetic pollution hunter also has to know when to stalk their quarry; breakfast and evening times are best, when people are likely to be using toilets, sinks and washing machines. Industrial areas are also likely to be busy at similar times of the day, allowing people on Outfall Safaris to spot and monitor where misconnections mean that untreated water is going straight into the river. While the Aire Rivers Trust are dab hands at cleaning up litter, any major fly-tipping should be reported directly to the relevant council authority (North Yorkshire, Lancashire, Bradford or Leeds, according to the stretch of river where the fly-tipping is found).

Putting it all into action

Brains thoroughly expanded, and knowledge of gooey and unpleasant substances, colours and aromas forever increased, we headed out in a crocodile chain to a small beck close by, a stretch of water which changed in appearance over the short time that we surveyed it. Some more recent pipes sat alongside older infrastructure, including a Heath Robinson contraption from the roadside high above. We had a go at grading the different outfalls once we had got our eye on them, firstly at spotting them, then secondly at judging if they met the 20cm minimum criteria. Wrapping the day up with a group photo on a bridge, we returned to civilisation, ready to use new knowledge on the stretches of river meticulously mapped out by Sam. And no, my smart sneakers were not adequate for the river path, but I managed to avoid falling in and becoming part of the river detritus myself.

Outfalls at Oddfellows (a poem)

Bright lights, PowerPoint on
Walking boots, bright-coloured coats.
Mugs of coffee, insulated water bottles.
Rob hanging on every word, poised to interject.
Kettle boiled, cups full.
Graphs, charts, images, the works.

The audience are polite, focused.
Relevant questions, print-outs to hand.
We spill out
Onto the pavement
Into the sunshine.
Beck time!

One pipe, two pipes, four
Blue paint, ‘Heath Robinson’
Fast-flowing water.
Peculiar arrangement
Alleviating the surface water.
Many points of interest on a short stretch.

Now time for me to be
Eastward bound.
A kind fellow musafir points
The way to the Wilderness
A little grotto
A haven from the crowds.
A place to linger, but there’s a train to catch

Now to meddle with Google docs
Entice friends to explore
Bring along someone new
One pipe at a time
Follow in Rob’s footsteps
Create a flow.

(Musafir is Arabic for traveller, from the same root as Safari.)
