My time going (Aber)Forward at Pwllpeiran

Guest blog by Damian Osmond

It was during that wonderful time of year we all know and love, exam season, that I received an email asking if I would be interested in working with the university as part of their AberForward scheme.  Looking for any excuse to distance myself from exams, I naturally filled out the applications and wondered idly about whether I’d see anything about the placement I opted for.  A couple of months later, I was stood in the wonderful hills in Cwmystyth, as we discussed agricultural practices with some visitors in what would later be dubbed as “my office”.

The feeling you’re experiencing now is an odd mix of tranquillity and envy.

On paper, my roles were rather simple; help out with what I could, learn some new skills and assist with analysis and data collection.  However, it did not take long for my responsibilities to expand massively.

I mentioned data collection, this varied from taking grass cuttings, daffodil measurements, so many daffodils…  Sheep weighing and soil core taking, which was nice but rather odd to hear metal striking across all the hills, echoing like thunder.  I also had the opportunity to speak with some visiting school kids.  Now, I’d never worked with children before, but it was staggering just how many questions were asked.  To this day, I have no idea how local wildlife in the hills lead to me trying to answer about reverse scuba octopi, but what I can say is that no day in my eight weeks working were ever the same.

The hardest day there was when we represented IBERS at the Royal Welsh; it was still early into my placement, I had some idea of information to share about moss, peat and water retention but the heat made everything seem much harder than it was. Still, whilst a hard day, it was not the worst, in fact, during my time here I never did have a bad day.

Never did find out if a rolling stone gathers moss.

Although, saying that, whilst not a bad day as such, the one I disliked most would have to be the day I overheard there would be sheep shearing and volunteered possibly too enthusiastically to assist with it.  The work was definitely interesting, and I can now say I’ve sheared a sheep!  (Even got to keep the wool.)  However, sheep are incredibly messy, and after the being avoided at lunch, due to the horrendous smell I had picked up, I had the joy of trying to remove many a sheep’s lunch and half a field from my clothes.

In all my time working with Pwllpeiran, my favourite role was just being part of the team; I was working alongside doctors, a professor, researchers and people with far more experience than myself but I was never treated less than anyone else or just as the temp to shift stuff or run tea.  I joked about my least favourite time there, but I think it has to be when I had to say my goodbyes and leave.  Still, the work done they do there is incredible, I could list all I learned but we’d be here until the next AberForward steps in, but I can’t thank everyone I worked with enough for the chance to be a part of the team, but thank you nonetheless!

From the old to the new!

by Hannah Vallin

Last year, Pwllpeiran obtained a small amount of funding for additional engagement from the Joy Welch Educational Charitable Trust, thanks to our PhD student Dan putting in the application.  The aim of the Trust is to provide funds for the promotion of educational outreach work.  So, what did we do with the funding?

The fun begins.

Here at Pwllpeiran we have many useful outbuildings surrounding our office centre. These include field labs for sorting and analysing samples collected from plots; drying and milling rooms; and garage space for the all-important machinery.  However, there was one particularly large space that was becoming a bit abandoned, collecting more and more boxes and cobwebs – it was time to make a change!  On a rare sunny day the whole team got to work clearing out the cluttered room, filling trailer after trailer with old rubbish, and re-allocating stored furniture.  It took the best part of two days to completely empty the space, and then the cleaning began….  Needless to say I made the others get rid of all the spiders!!  After endless hoovering and mopping, the place was clear and clean, and we could start to envision how to revamp the space.  As it is a breeze-block building we decided a lick of paint was needed to brighten up the space; even the floor got a shiny covering of paint.  With the addition of some benches, tables and notice pin boards we had a turned a dusty out-room into a great space to use for multiple events!

The big clear out – go team go!

As someone who loves to engage and inspire children into the world of science, I am keen to develop educational field sessions held at Pwllpeiran, making use of our newly revamped outbuilding, aka the ‘field classroom’.  Pwllpeiran represents a unique resource for education and research; for the University, local groups, and schools.  Thanks to the funding from the Joy Welch it was possible to purchase some ecology kits, magnifying lenses, vegetation quadrats, identification cards and tables for the new classroom.  With these facilities in place we were ready to invite small school groups to Pwllpeiran, offering the chance to attend organised ecology fieldwork sessions based on interactive learning experiences out in the field, supported by the field classroom back at the centre.

Finished, and ready for an event!

Since establishing our field classroom, we have had two visits from Plascrug Primary School, and held a session as part of Aberystwyth’s Summer University program.  Both events were very successful, thanks to my trusty sidekicks, PhD students Caroline, Ben and Dan who helped run the sessions!  Everyone, even the adults, had a lot of fun! Wellies and waterproofs on, everyone was ready for river kick sampling to identify fresh hv4water invertebrates and mini-beast hunts in the woods and grasslands.  Our best find was a bright pink and olive-green Elephant Hawk moth, caught by a young pupil who at the age of 10 already knew she wanted to be a zoologist (girl after my own heart!).  Plus, some budding botanists of the future very much enjoyed showing off their plant and tree identification skills.  Not to forget my favourite activity: learning all about super Sphagnum and its role in our pristine peat bogs.  It really has been a great experience to show off the area around Pwllpeiran, but the most rewarding part is seeing first-hand the excitement and inspiration on the pupils’ faces from the opportunity of learning in the great outdoors; priceless! As a certified STEM (science, technology, engineering and mathematics) Ambassador, along with the team at Pwllpeiran, I plan to continue developing our connections and educational outreach work with the local community.

For those of you who keep an eye on our Facebook page (find it here) I am sure you will have seen additional events over the summer, such as our Open Day and the Miscanthus safari tour, also took advantage of our new snazzy field classroom (yes, the name is sticking).  Look out for more events and visits in the future!!

Heat from the Hills

PROGRASS

Rank Molinia tussocks – a fuel of the future?

by Mariecia Fraser

A few months ago, we were shocked and deeply saddened to lose our friend and colleague John Corton.  This blog is about an area of research he was tremendously passionate about.

Managing native grassland is a challenge right across Europe.  Its low nutritional value together with declining stock numbers has increasing led to under-grazing and agricultural abandonment.  But what other land use options are there for unimproved, semi-natural vegetation?  Especially if it’s been taken over by problem plants such as bracken, rushes and Molinia (purple moorgrass).  Dominance by these brings big biodiversity challenges, and large areas of hill land are now being mown by conservation bodies such as the RSPB, National Trust and Natural Resources Wales to try and maintain habitat value.

ProGrass was an EU project which was the first to consider bales of discarded vegetation being produced by this type of land management as a potential feedstock for bio-energy.  IBERS worked with partners in Germany and Estonia to test a pilot processing plant that turned this biomass into a liquid substrate for anaerobic digestion and a dry cake for burning.  The vegetation was cut and baled using standard (but robust!) farm machinery any time from mid-August on.  One of the advantages of using this type of vegetation as a bio-energy feedstock rather than a forage is that the decline in herbage quality over the autumn and winter doesn’t matter.  And waiting until the ground is frozen can mean areas that would normally be too wet to access can be cut, helping to knock back e.g. rushes.  Lots of great data was collected as the processing plant (known as Blue Konrad to his friends) toured across Europe.  Testing of the material produced confirmed that minerals that could damage boilers had been removed from the dry cake, making it suitable as a fuel.

The processing plant (a.k.a. Blue Konrad) in Germany

Several follow-on projects have taken the ProGrass concept further.  Burning material at high temperatures without oxygen (a process known as pyrolysis) produces char, which everyone who’s ever had a go at cooking with charcoal knows has a high heat potential.  It’s also a great way of concentrating energy into something small and light.  Mobile char rigs could offer a great way to make the most of material located in inaccessible areas that would be too costly and difficult to transport out as bales.  The latest project has us working once again with several of the ProGrass partners plus new collaborators across Europe to broaden the range of ‘waste’ green material being considered even further.

If the technical challenges of scaling up can be met and the economics work out we could have a triple win: reduced reliance on fossil fuels without growing extra biomass crops; improved biodiversity; and an alternative income stream for land managers.  And there’s an awful lot of land we can use without damaging sensitive areas.  The ideal set up could be to establish areas that are cut annually on a rotational system; with stock grazing on the greener, more nutritious, growth the following year; then a fallow year or two to build up the biomass again.  At a landscape scale this would be a great way of creating mosaics of vegetation at different ages and heights – just the sort of thing our rare upland birds and other wildlife love.

Adventures with a camera trap

Adventures with a camera trap

by Ben Roberts

An area rich with diversity 

We’re not short of interesting animals in the area around Pwllpeiran. Doubtless many of you will know about the presence of some of them, from iconic raptors gliding in the skies above, to the variety of wildlife in the woodlands around Hafod and beyond.  The diversity of sometimes rare and endangered species in the area is plain to see, whether it be on a trip to Nant Yr Arian to see the red kite feedings, or evidenced by Vincent Wildlife Trust staff out and about on the roads or scouting the forestry for pine martens and pole cats.

Finding the motivation…

Knowing this, I had always liked the idea of going out at some point to attempt to photograph the animal wildlife that might be present around Pwllpeiran. Unfortunately, a number of factors including frequent wet weather, lack of spare time, and a general lack of patience to sit out on the hillside for hours on end hoping to see something more than just sheep meant somehow I never got round to it….  However, this time last year it began to become a reality via an unlikely route.

Daffodils on the menu?

IMAG0035

No daffodil grazing, but ‘Larry’ the lamb was very keen to show his best side

Having completed our first daffodil harvest, we were preparing to put sheep back out on the plots to let them eat the grass which had grown in their absence whilst the daffodils grew, when we came across a conundrum. We had always believed that the sheep would be unlikely to eat the daffodils, given that the alkaloids
which we are after are actually in the plant to stop mammalian herbivory and were expected to make the plants bitter.  But given no one had tried this combination before, we lacked solid scientific data as to whether our assumptions were true or not. So the question was, how do we check that the sheep aren’t eating them?

Finding a hands-off method

Being the lowest grade member of staff, and knowing that a suggestion of a straw poll was unlikely to win out as the method of deciding who had the honour of keeping a vigil over the daffodils, I decided to quickly search for a solution that involved a less hands-on experience!

Having seen a good deal of BBC nature documentaries throughout my life, I knew that camera traps were a good way of catching animals in action without having to be there. You simply strap the camera to a tree or post facing a trodden path or area where animals are likely to be seen, and leave the camera on standby ready to snap/ record at any time when something crosses its field of vision.  This led me to think this might be a useful solution.  Rather than looking out for exotic wildlife, we would simply have the camera overlooking the daffodil rows, and when a sheep came in its vision we would see whether they were just eating the grass or choosing to sample the daffodils as well.

The adventures begin!

After a few stints at a few different places, we felt confident that the sheep weren’t eating the daffodils.  It was at that point we realised that now having a spare camera trap, we could maybe have a look at some wildlife after all.  We started putting it up at different places around Pwllpeiran, and because it didn’t require us to be there – we could leave it for weeks at a time taking pictures and videos.

Below are a few of the sightings we’ve had…

IMAG0017

Its not just sheep on the plots, this polecat was found hanging around.  Can you spot it?  It’s hiding behind the daffodil leaves.

Despite the rarity of deer in the area (see previous blog), there have recently been one or two sightings not too far from Pwllpeiran, and there was lots of excitement when we managed to get one of them captured on camera.  But it was travelling at speed, and it’s not clear from the image what type it might be.  We’ve had a go at re-positioning the camera to try and catch it head on, but haven’t had any luck as yet.

Birds are a lot more easier to catch.  Here’s a a blackbird playing hide and seek.

 

But it’d better watch out for what’s lurking in the undergrowth!

Messing about with moss… (it’s educational, honest!)

by Caroline Freeman

I am not based at Pwllpeiran, but am perhaps best described as a ’part time’ team member. I’m a first year PhD student and am making good use of Pwllpeiran for my project, studying the impact of management on soil water infiltration, with the aim of understanding links between land use, land management and flood risk. I love being outdoors instead of in an office, so escape up to the hills whenever I can.  I have a background in ecology and environmental education, having worked as a countryside ranger for many years in Scotland, as a warden at Ynyslas Nature reserve and more recently as an Education Officer for Natural Resources Wales. I’ve always enjoyed education work, so when I heard that Pwllpeiran were planning to organise a stall for the University science week I was keen to get involved. They were also planning an activity focusing on sphagnum moss, which plays an important role in flood mitigation, something very relevant to my PhD.

During Science Week, a range of hands-on exhibitions at Aberystwyth University are provided for over 1400 school children from around Wales, as part of British Science Week, to enthuse young people about science. The fair is organised by the University’s Centre for Widening Participation and Social Inclusion (CWPSI).

Collecting moss on the hill

Lots of different departments get involved and the activities can include anything from guiding robots through mazes, to making slime and playing with model rivers.  We wanted to provide hands-on activities to demonstrate the important role that sphagnum moss plays in storing and filtering water. Luckily, Hannah had the answer – a ‘high-tech’ solution that involved water, a bucket of moss, and a little bit of digging…

Our stall consisted of three activities. Firstly, sphagnum soaking in water was placed in one tub, next to another holding some sponges soaking in water. The schoolchildren could grab a handful of sphagnum to see how much water it holds, and compare it to a sponge. This was a very popular activity, with the pupils enjoying squelching and squishing the sphagnum moss. It gave us a chance to chat to them about how sphagnum could help mitigate flooding, by storing large amounts of water and reducing surface run off into the rivers.

Secondly, three tubs with three different types of vegetation cover were set up next to each other. These had been dug up from Pwllpeiran, there are some nice square shaped holes somewhere up there now…   One tub held peat soil, one had soil and grass, and one had soil and sphagnum. Water could be added to the top of these tubs, which ran through to clear plastic bottles underneath.  Children could see first-hand how much water came through each tub, and also compare the colour of the water and amount of sediment it carried.  There was less sediment in the water that had run through sphagnum, showing the role it plays in filtering water.

Showing how sphagnum helps to manage water

Finally, some microscopes were set up so that the pupils could compare dry and wet sphagnum and see the differences in shape and structure as it took on water.

We had many visitors to the stall, so with a bit of luck some young people went away with a new interest in environment, the natural world and the difference one small plant can make to the natural world.

Following the success of the science fair, we are planning more education group visits to Pwllpeiran, watch this space!

 

Horsepower and hats (Stepping back in time: Part 1)

By Mariecia Fraser

Old photos and films can give such fascinating insights into bygone days.

“Shadow on the Mountains” is a short film showing life in the hills in 1931 which is free to watch on BFI Player.  It has no audio or soundtrack, and this together with the jerky haste of early films gives a real sense of atmosphere.  Much of the film is shot on steep hillsides typical of the sudden transition from valley floor to high upland plateau.  Men incongruously dressed in Sunday best, complete with ties and hats, head out to gather their sheep.  They ride stocky little hill ponies and are accompanied by a motley collection of working dogs.  Shots of abandoned mine workings are a reminder that other ways of life have come and gone in these areas.

Later footage captures the more rolling and fertile lower lands near the coast and the crops grown these.  This gives a link to a section showing experiments with grass and clover underway in the greenhouses of the Welsh Plant Breeding Station, which had been opened in 1919 (see more here).  We see scientists with a surprisingly simple set-up doing pioneering work a world away from the high tech systems of today.  Back up the hill a caterpillar tractor and plough working at an alarming  angle and speed prepares ground for reseeding with these new, improved grasses and clovers, leading to concluding shots of an apparently contented ewe chewing her cud with her lamb by her side.

What is striking is how similar much of the landscape is to what you’d see today.  This is a time well before support subsidies and headage payments, yet we see vast tracts of the same floristically challenged grasslands that are now considered synonymous with over grazing.  No trees, no heather.  It’s just one area,  but it’s a reminder that it’s often worth questioning just how good the ‘good old days’ really were.

 

From staff to student (again)

Decisions, decisions…

This time a year ago, February 2016, I was writing the first posts for this blog; very much into my job at the time and not really wondering what was going to happen when the fated day of September the 6th rolled by and my contract was to finish. Having spent 6 months (with 5 remaining) as a KTP Associate; mapping the pipeline for producing the Alzheimer’s disease drug galantamine from daffodils and supplying the related QA documents; I hadn’t bothered to worry myself too much on the future.download

Though, unfortunately as it does, time went ticking by. And by the beginning of June I was beginning to scratch various parts of my head quite a bit over what I should do come the big day. Fortunately, my nails and receding hairline were saved from too much damage.

One particularly wet lunchtime (we get lots of those at Pwllpeiran), Mariecia asked me what I wanted to do post contract – a dangerous thing to ask any not-long-graduated 22 year old. I had however been mulling it over in anticipation of such a question. Having greatly enjoyed my job, my time at Pwllpeiran, and the university in general- I thought that given the opportunity I might like to stay on. I also realised that the thing I enjoyed the most was the research side. And fortunately, when Mariecia told me about her future projects – one in particular stuck out.

Sooo, what was this new project?

Well, it was an upcoming PhD project due to start in September 2016. A collaborative project between IBERS, the computer science department, RSPB Lake Vyrnwy, and the Elan Valley Trust titled ‘Understanding and exploiting livestock behaviour to manage upland vegetation for wildlife and ecosystem services’ (catchy title i know!).  70a57409a2cb2f99a7951f54883c4023_vector-white-sheep-eating-a-sheep-eating-clipart_1300-1025An application led to an interview, the interview led to an offer, and here I am.

The basic premise of the project is to understand more about how, and why cattle, sheep and ponies eat what they eat; what influences their choice, and by knowing this- can we manipulate the influencing factors so they eat what we want them to? The utility of this being to create grazing prescriptions that could be used to help restore habitats that are often impeded by certain vegetation e.g. Molinia caerulea over-dominance on restoring upland blanket bogs.Which when we consider that these habitats provide valuable ecosystem
services, such as climate regulation (UK peatlands contain at least 3000 million tonnes of carbon, which is twenty times as much carbon stored in the whole of the UK’s forest biomass (IUCN, 2009))- it seems important to try and restore them as best we can.

  “I trust you can handle this contraption, 007?”

One of the real fun parts of this project is the collaboration with Aber’s Computer Science department. Given the scale of plots used in this study, and the need to know where these animals are at one time- we joined forces with Comp Sci in order to try and develop some specific equipment to do the job. I wont say too much now, as they’ll be a blog on that at the beginning of next month, but to keep the suspense going I will say it involves specially developed electronic ear tags, and auto piloted drones (exciting i know!).

Until next time!

Lots to look forwards to I’m sure!
