100 Hours with Aire Rivers Trust!

Betsy Matten (now proudly BA Hons.) writes about her placement with our Trust.

As part of my final year studying BA Geography with Quantitative Methods at the University of Leeds, I undertook a 100 hour placement with the Aire Rivers Trust (ART). ART immediately stood out to me, as a human geographer looking to gain insight into the world of environmental conservation, so I reached out and asked if I could get involved. From the very beginning, I was introduced to a variety of exciting projects, as well as many members of the team, a group of incredibly passionate and kind individuals.

During my time with ART, I managed to get out on some practical conservation days, working on important tasks with the amazing local volunteers! From scrub clearance to hedge laying, it was eye opening for me to see the work taking place on the ground to protect the Aire and its natural ecosystems.

Meeting the ART volunteers was a real highlight of the placement for me, showing such dedication to their local river and its tributaries. At a time when the topic of nature and the environment can evoke feelings of anxiety, this was a much needed reminder that there are many passionate people working towards a better world! 

My key project with ART involved working closely with the Catchment Coordinator, Ruth McBain, who really supported me throughout the placement. This project was focused on Catchment Management Planning. I undertook research around best practice across the UK, and began to compile information which could be used for ART’s updated plan.

A proud achievement for me was the publication of a web page and interactive map I created on the ART website. This page aimed to direct potential new volunteers to the best ways for them to get involved. The map involved the collation of many of the existing local action groups along the Aire, including contact details and a blurb to assist viewers in choosing the most suitable group for them. This webpage can be found here: https://aireriverstrust.org.uk/friends-of-the-river-2/ 

I thoroughly enjoyed every part of my placement. During a very stressful period of my education, the ART work provided me with engaging and inspiring days to break up the endless library sessions! In addition to this, my portfolio on all of my ART involvement received a high first class mark.

Thank you so much to the brilliant team at ART, for an invaluable 100 hours, I loved it!

Roots in the River: Celebrating Spring and connecting with nature!

Welcome to our blog series as part of our Roots in the River project, where we will be sharing different stories and experiences as the seasons pass by. First up – celebrating Spring and connecting with nature!

Having passed the spring equinox on Friday 20th March, spring is officially here! Over the past few weeks, we have seen shoots appearing, the first flowers of the year blooming, and that cold edge in the air has gone. Spring offers a great opportunity to get out into nature, connecting with the natural world to reap the well-being benefits it can offer. As the cold and shorter days of winter have passed, engaging communities with nature becomes easier, as many people are ready to be outside again, and the natural world becomes a more inviting place to be. Rivers are a great place to bring people together. For those of us involved in conservation work, surveying, or simply walking the same stretches of river regularly, spring is when everything starts moving again.

Connecting with nature has been shown to provide us with many benefits, such as improved mental wellbeing, greater meaning and purpose in life, and more pro-environmental behaviours (University of Derby). Nature connection can be very simple, it is about the feelings you get whilst in nature. Spring is one of the easiest times of year to feel a real connection to nature, especially when walking by a river. The senses seem to wake up along with the landscape. The more time you spend in nature, especially in spring with longer days and warmer weather, the more you realise that nature connection comes from noticing small things, using your different senses to recognise them, and think about how this makes you feel. Standing by a river at this time of year, you are reminded that nature connection is not complicated, it involves simply being present long enough to see, hear, smell, and feel the natural world around you.

Spring can also provide an excellent time to feel inspired! Through our Roots in the River project, we have recently run some river workshops with the Art4All groups at Keighley Healthy Living, where we explored different river themes and took inspiration from various photos and a visit to the River Worth. The groups are currently producing some wonderful river related artwork that will be displayed at an exhibition at the KHL centre on Saturday 25th April.

Next time you walk near your local river, or are passing by some nature, take time to notice and pay attention to any wildlife around you. You might notice new buds and shoots on ash, beech or oak trees, leaves emerging from alder, field maple and silver birch, or blossoms blooming on blackthorn and crab apple. Look out for pollinators too as they begin to move around to feed on newly grown flowers. Peacock, comma and red admiral butterflies can be spotted this time of year, and you could also spot beetles, spiders and ladybirds. You may also spot some special migrant bird visitors that return to the UK after spending the winter in warmer areas, including blackcap, chiffchaff and wheatear.

At the Aire Rivers Trust, practical volunteer days, guided walks and surveying activities can help people notice things they might otherwise pass by. Why not join us on one of our very rewarding volunteer days, which run on Thursdays and Fridays, or help us with our citizen science monitoring programme.

Trench Meadows – helping an SSSI recover

Trench Meadows is a Site of Special Scientific Interest (SSSI) off Higher Coach Road next to Load Pit Beck and not far from Shipley Glen. The site contains 4.7 hectares of lowland meadow – a nationally rare habitat. The grasses in the neutral grassland on the site include red fescue, sweet vernal and crested dog’s-tail; wildflowers include herb black knapweed and bird’s-foot trefoil. Devil’s Bit Scabious (Succisa pratensis) also indicates the importance of this species-rich grassland. The land adjacent to the meadow is designated as a wet woodland with common alder being the dominant tree species.

The site is owned by the City of Bradford District Council and managed by The Countryside Service, with support from the Aire Rivers Trust. Aire Rivers Trust volunteers have carried out several tasks on both the meadow and in the wet woodland including Himalayan balsam removal, scrub clearance and hedgerow maintenance.

Volunteers make a difference

To date, Aire Rivers Trust volunteers have contributed 335 volunteer hours. 540m2 of scrub has been cleared, which otherwise would have resulted in the meadow becoming woodland. 900m2 of Himalayan balsam have been pulled across the site. The holly hedgerow on Coach Road Bridleway has been improved to provide habitat and act as a stock-proof barrier. Aire Rivers Trust works in partnership with several organisations. West Yorkshire Combined Authority, WSP and Keighley College have all contributed volunteer time to carry out practical environmental tasks.

A local farmer grazes the site, with cattle selectively grazing scrub, keeping down bramble encroachment and providing soil improvements. Bradford Council Countryside service has also undertaken willow thinning on-site to prevent woodland succession.

The site has permissive access for the public and visitors are encouraged to stick to the path and keep their dogs on the lead to prevent disturbance of wildlife and prevent dog fouling. The Trust will continue to carry out management works on-site. To find out more please visit our volunteer website: Volunteer with Us – Aire Rivers Trust

Ellie’s Weir…ed Blog

In this post our GIS whizz Ellie Spilsbury outlines some of the work we have been doing to identify ways to improve the sustainability of the fisheries in our rivers and hopefully aid the return of salmon for the first time since the Industrial Revolution.

Look closely and you will see hundreds of Minnows collecting at the bottom of this weir, unable to ascend. See the area in the water that looks dark brown; they are Minnows.

A familar story

Once upon a time, our River Aire had the highest Salmon population of any Yorkshire river. Then came the Industrial Revolution, which saw the wool and fabric industry boom throughout Yorkshire. Mills were constructed accompanied by weirs to harness our river’s energy. Although the mills are now closed and are becoming swanky new flats, the weirs often remain, isolating ecosystems that lie between them. Weirs disrupt the natural transport of sediment downstream, causing a build-up of silt and gravel behind the weir, which is detrimental to the habitat of spawning fish. Since 2011, one of the Aire River Trust’s goals has been to increase the connectivity of our river and its tributaries by removing or re-configuring weirs to allow fish passage. Following earlier work to install fish passes through and downstream of Leeds, significant steps towards this goal were made in 2022 with the successful construction of four fish passes as part of the DNAire project.

When we see water flowing over weirs, creating the sounds of waterfalls and visually pleasing white waters, it is easy to forget their man-made heritage and artificiality. It is hard to imagine seeing through the eyes of a migrating trout or salmon; every cell in its body instinctively directing it upstream to spawn, using both the stars and the earth’s magnetic field for navigation and then facing an unpassable wall of Yorkshire-dressed stone. It is often not just the height of the weir that presents the issue but the combination of weir height and the shallow depth of the concrete sill below the weir. The height at which salmon and trout jump is directly affected by the relative depth of the water at the foot of the barrier and the “hydraulic jump,” which boosts their leap.

The Environment Agency (EA) has identified around four hundred river obstacles within the Aire Catchment. However, we believe there to be many more. For example, the EA recorded two barriers to fish passage on Pitty Beck, yet on our Bradford Becks Walkovers, we found 11. This pattern is most likely repeated on each beck.  Currently, tackling the removal of every weir in the catchment is unattainable. So, how did we prioritise them into a workable top twenty?

Data analysis with a Salmon splash of professional opinion

With help from The Rivers Trust, we are the first regional rivers trust to code an ArcGIS tool to accurately calculate the length of a river (including tributaries and forks) that would be opened and re-connected by the removal of every mapped weir in the Aire Catchment. Alongside this, we analysed ecological assessment data, invertebrate biodiversity, local community data (including deprivation), and weir visibility to the public. We assigned a score to each outcome and designed a weighted decision-making matrix that identified the weirs that scored the most highly. The data only tells us half the story, so we took our results to our expert team and discussed those weirs for which a solution in the short(ish) term might be feasible.

Once we had twenty feasible weirs, it was time to ground truth our ideas. The purpose of site visits is to add or, more often, diminish our confidence in the feasibility of the weir so that we only carry the most achievable sites to the next stage. We evaluated the weirs’ condition, site access, utility services or abstraction points, and landowner engagement by photographing and recording the area, our thoughts, and encounters.

The most surprising discovery for me was the actual size of a weir. After months of viewing photographs without visual perspective, weirs can appear to be half the scale of the real-life structure. Take a moment to analyse this photo: how tall do you believe it to be? See the very bottom of the blog for the upside-down answer.






(Tr)outcomes

We are fast approaching the end of the site visits and write-up stage. It is time to narrow our shortlist of twenty weirs down to four. So, it will be back around the table for our professionals to decide on the four “leak” proof projects to invest in. These four weirs will be subject to a comprehensive feasibility study and design process. I hope my next blog post will include more designs, machinery, hard hats and re-naturalised rivers.
