Jumbles: Pond Restoration

Pond Restoration 4th May 2025

As well as a big reservoir Jumbles Country Park also has some smaller water bodies that are less well known. In May 2022 we began a restoration project, back then the ponds had become overgrown and shaded out by vegetation. The ponds were dredged to remove leaf litter and silt and oxygenating plants were introduced to the ponds. Brash and branches were cut back and used to create linear habitat piles, Himalayan balsam was pulled up or cut down.

In May 2023 we came back and the areas around the ponds had transformed from a lunar landscape to a carpet of flowers, the work continued with cutting back invasive vegetation, and planting marginal plants.. and a bit of pond dipping. Today’s task involved cutting back willow from around the pond to let in more light. We used the chipper to process most of the brash and spread the resulting chips along the path, the rest of the brash was used to create a linear habitat pile. Want to know more about ponds? Then have a read of this.

In 2023 we found toad tadpoles, this year we had alder fly larvae and baby newts. The ponds should continue to attract frogs and toads as well as insects such as dragonflies. Thanks to everyone involved and big thanks to Tom and Caroline for organising and keeping the group going.

Darcy Lever Marshes: New Frontier

Pond Management 9th March 2025

Darcy Lever Marshes is a new site for Bolton Conservation volunteers. The site is hidden between housing estates near Hollycroft Avenue, playing fields and Radcliffe road and if one of Bolton’s secret wildlife havens.

The marshes provide habitat for great crested newt and other amphibians, and potentially could benefit dragonflies. About 20 years ago Dave Orchard and the Amphibian and Reptile Group for South Lancashire developed the site but willow trees are now starting to take over and threatening the site’s usefulness, a process know as succession (to find out more about succession see this earlier post).

We were last here in November 2023 when BCV and Dave Orchard removed willow trees that shading ponds deeper in the marshes. As this is privately owned land we had permission to burn all of the material we cut down, on this particular site this method of disposal was preferable to making habitat piles.

This time we were working on a different pond. Trees were shading out the pond and needed cutting back, the brash produced was used to create a linear habitat pile along one edge of the pond to deter intruders

Many thanks to the site’s owner for allowing us to work on this site, Tom and Caroline for organising and everyone who took part. Photos from both tasks below.

Anderton Centre: Winter Resi

8th-9th February 2025

When we first came to the Anderton Centre on Lower Rivington Reservoir in January 2007 the site was dominated by rhododendron. It took us 4 years to bring and end to this sea of green, using bow saws, mattocks, winches and brute muscle power. Over several years we returned to do other work to help both improve the site for wildlife and as an outdoor education centre by planting trees and hedges, repairing walls, building footpaths and habitat management. This year we returned again for our Winter residential, or resi as we call it. Our work this season would involve repairing dry stone walls, clearing some scrub, and trimming hedges. This was also the last winter resi we do here, although we will still be doing the summer resis.

The first task of the weekend was to clear an area large enough for a shipping container to be installed. This involved removing a couple trees and some scrub, and also moving a pile of brash.

The wallers repaired several sections of wall along the front of the reservoir. Why the walls had collapsed is anyone’s guess: livestock rubbing against them, people climbing over them, tree and root growth, land movement, or a combination of factors.

Well that’s the work bit done, but the other reason people go on resi’s is the social angle. For those staying over-night there was plenty of time to fill, and most of that time was filled with beer, banter and being silly. After work on the Saturday we hurried through the cold and dark to The Bay Horse. Like Hobbits at the Prancing Pony we sampled the ales, but thankfully there were no hooded figures with pointy swords. After much merriment we rushed back for Lynn’s evening meal. Meaties and veggies both being catered for.

The morning came and kicked everybody out of bed into the kitchen for breakfast and second breakfast. Between breakfast and dinner, or lunch if you prefer, we finished off the walling and finished the day by trimming the hedges we planted in previous years.

Many thanks to Tom, and Caroline for organising, the Anderton Centre staff for having us back, and to everyone who attended the weekend. Special thanks to Lynn and Trish for catering, doing a great job as always.

Chew Moor: Hedge Laying

Hedge laying at Chew Moor Lostock 26th January 2025

Hedgerows are not a naturally occurring feature of the landscape, they are a consequence of human land management. The oldest hedgerows date back to the Bronze Age and were originally remnant woodlands left around land that had been cleared for farming or settlements. Over the centuries these leftovers became an established method of creating field boundaries and an important feature of our landscape, increasing in usage through Roman times and the Medieval era.

As farming became more mechanised, and post-war intensive farming practices were implemented to feed a growing population, hedges were destroyed to reclaim a few extra yards of farm land, in doing so they changed a landscape that had endured for generations. What wasn’t fully appreciated was the impact this had on wild life. Wild life had taken advantage of this human creation; nesting birds, pollinating insects, wild mammals all found a home or sanctuary in hedgerows. As hedgerows were systematically destroyed biodiversity and species populations fell. By the mid 1990s the loss of hedgerows had largely stopped, but by then many hundreds of thousands of miles of hedge had been lost.

Thankfully, the conservation value of hedges has been recognised and hedges are making a comeback.

If left alone hedges will start to fail within a few decades, individual shrubs become thick and woody and gaps appear in the hedge as they die, the hedge soon loses its form and function. Hedge laying is the best way to manage a hedgerow. Hedge laying prolongs the life of the hedge, improves its function as a field boundary and provides increased habitat for wild life. There are many styles of laid hedge, BCV use a Lancashire style which, while being a bit rustic in appearance, is very effective. The methods of laying a hedge are also varied. On today’s task two methodologies were used: using a bill hook and using a saw.

Generally the process for both is the same: decide which way direction the hedge is being laid, if the land slopes upward that’s the direction the stem or pleach should go. Next clean up the side branches of the stem you’re working on. If you are using a saw make a cut two thirds of the into the stem several inches above the ground on the opposite side of the stem to the direction you want to lay it; if you’re using a bill hook slice downwards to that point from a point a foot or so up the stem so that the cut tapers inward. Then the stem, or pleach, is bent over in the direction you want it to go. Repeat with each pleach until the hedgerow is complete. Hammering stakes as you go along gives the newly laid hedge support.

Today’s task was at Chew Moor and led by Francis and Nathan. Well done to both for doing a great job and to everyone who turned out.

Nob End: Everything In Apple-Pie Order

Orchard tidy up 22nd September 2024

A few years ago Tom planted some apple trees for the Canal Society. Our first task there was on Easter Sunday in 2022, in an area not far from the place where James Mason ran down the cobbles in Spring and Port Wine. Although I’m sure our own James would have preferred cider with Rosie, it was all a taste of honey and we looked forward to returning at a later date.

In the 2 years of Saturday nights and Sunday mornings the site had become over grown with willow herb, balsam, bramble, and the odd sprig of bracken, and so need a good clearing out. So, armed with loppers, bow saws and no fear what so ever we started the task.

Cutting through the brambles would have been easier with something a bit bigger than loppers, but within a couple of hours we had started to clear the site. As well as the vegetation we also removed hawthorn and pushed the tree line back a few metres to reduce shading and competition. Everything that was cut down was used to create a linear habitat pile, or dead hedge.

Apple trees provide habitat for invertebrates, pollen and nectar for pollinators, and fruit that can be eaten by a variety species from birds to foxes; as far as wildlife goes apple trees are the room at the top.

BCV: The Show Goes On

Three Tasks in June 2024

Between Rick Parker’s passing and his funeral we had three tasks. Although we no longer have Rick leading the group our work continues; nature doesn’t stop and neither do we.

2nd June – Moses Gate Country Park
After a 30 second silence in memory of Rick (chosen because 30 seconds is the longest he could go without talking), we got to work clearing Himalayan balsam from the woods around Rock Hall. I won’t go into details about balsam bashing but if you want to know more about it follow this link to the beginners guide.

16th June – Grimeford Village
Our second task of the month was just down the road from the Anderton Centre and involved dry stone walling for United Utilities. The wall wasn’t just in disrepair it was a pile of rubble. We re-built a good stretch of it but still plenty left. Walls have both landscape value and wildlife value; they are a part of the character of the countryside plus they provide corridors and refuges for invertebrates, amphibians, small mammals, and even small birds.

30th June – Dunscar Woods
The Woodland Trusts millennium woodland has a balsam problem. Last year we cleared vast areas of woodland of this invasive non-native plant but this year it’s back again. It will take a few more years before we exhaust the seed bank and start to see the benefits of our work.

Conservation is not a ‘quick fix and move on’ operation, it’s a long term campaign to improve and maintain habitats, something Rick knew very well and always had in mind when planning tasks. It’s not about this year or next year, or even the next decade, environmental protection needs to seen in terms of centuries until what has been lost has been restored. BCV is proud to be a part of that legacy, we may not get to see the end results of our work but we work towards that end just the same.

Thanks to Tom and Caroline for organising, to everyone who turned out on the tasks above, to all BCV members past, present and future, and to conservationists everywhere working to make a better world.
