After I had finished
school I was looking for a job, project or organization where I could gain new
experiences. I worked a lot in hotels, restaurants and coffee shops but I
wanted to find something totally different before starting my apprenticeship in
Accidentally, I found
out about the Scottish Invasive Species Initiative (SISI) project on the
internet and fortunately they agreed to host me for a three-week internship. In
advance, Karen and Al (the local SISI Project Officers) helped find accommodation
for me in a shared student apartment and for the second part of the internship
I was camping at the Findhorn Foundation.
Finally, my internship started and I was welcomed by friendly, warm and funny people. Most of the time it was hard work, crawling through bushes to find and cut Giant hogweed, but it felt easy because of the fun and laughs we had together. I also had the opportunity to take part in an animal tracking course, learned about invasive species, and I learned a lot about the anatomy of birds and fish.
I was amazed how diverse the tasks in this kind of job are: On top of the work against invasive species, the work demands a lot of creativity – at events I coloured in fish masks with children and I helped to craft a giant hogweed with paper, felt, glue and wire.
I would recommend to everyone
who likes adventures, being in nature, new tasks and wants to get an insight to
a varied job, to take the chance to volunteer with the SISI project. Thanks to
the three project officers (Karen, Al and James) I had an unforgettable time, a
lot of fun and on top of that I got to see beautiful, unpopulated places in
Al Reeve, Project Officer, Scottish Invasive Species Initiative, June 2019
In an era where people are increasingly environmentally aware and there is a move away from the over-use of chemicals we want to investigate a solution to invasive species control that can be done inexpensively, at low intensity, and with minimal environmental impacts….so, enter the humble sheep!
This trial project by the Scottish Invasive Species Initiative is a practical experiment to discover if a land manager could use sheep to control a substantial giant hogweed invasion. A previous sheep grazing trial, by the Deveron, Bogie and Isla Rivers Charitable Trust at Auldtown (near Huntly) which began in 2013, shows that in a controlled environment, sheep can make light work of giant hogweed infesting a field. (Read the Auldtown Grazing Report). However this new trial is not just about measuring the impact of the sheep on the giant hogweed and woodland environment, but of the real life example of managing the site and sheep from the farmers perspective, recording the successes, failures and lessons learned from the outset.
The new trial site is at Kirkside Farm, Macduff, where we are working in partnership with the Gordon family who farm here. It is a 1km stretch of woodland sandwiched between arable fields and the River Deveron. Giant hogweed has begun dominating the woodland, particularly around the sunnier edges, and along the numerous streams that flow through the wood to the river. In the past, attempts to control the giant hogweed has been via pesticide application using a knapsack sprayer, which proved very time consuming and costly. Due to the scale of infestation and the difficult terrain of the site so far little progress has been made in restricting the giant hogweed’s expansion.
After fencing in the site, in April this year we released 25 sheep into the woodland area, asked dog walkers to keep their dogs on leads and waited to see what happened… and for the first month, nothing did! The sheep lazed around the entrance to the site, maybe due to the new environment or maybe because they had never eaten anything other than grass before.
During this time we started mapping the extent of the hogweed through the site both though ground surveys as well as using drone footage (courtesy of TAHR Media) to visualise the infestation. Working in partnership with The University of Aberdeen we will be monitoring the site and have developed a base map of the hogweed which, after an annual survey, we can compare to. We have also identified 40 monitoring spots where we will measure the effect of the sheep on the rest of the woodland vegetation.
As time went by though, we
started to pick up more indications of the sheep growing in confidence with
clear trails developing through the wood showing where the sheep had been
walking as well as a few nibbled hogweed stems.
Fast forward a couple of months and the sheep have well and truly gained a taste for the hogweed. There are now large patches of much-munched hogweed, a huge change from previous years. It’s worth mentioning here that sheep don’t actually kill the hogweed plants just by chewing on them but by restricting the plants from flowering they are slowly removing the amount of energy stored in the hogweed’s tuberous roots. Hogweed take 3 or 4 years to mature before finally sending out a flower spike to release seeds but by continually grazing the plants sheep can stop the older plants from flowering and mow down new seedlings as they emerge from the soil.
The alternative control method of using a broad spectrum herbicide like Glyphosate results in the killing of the target plant but, however carefully applied, also results in some collateral damage of the other species surrounding it. This has the effect of opening up the soil which enables more hogweed seedlings to germinate and fill the newly cleared space. One of the many benefits of grazing as a control method is that the ground flora is not killed off and this acts as a barrier against hogweed seedlings emerging.
Despite the great work of the sheep this year, there are still some patches of hogweed that have grown too big and dense for the sheep to get on top of and so this first year has not been a complete success, but we’ve learnt a valuable lesson – next year we need to get the sheep on site earlier in the year. However, on a positive note we’ve been delighted by the response of the site users and dog walkers in acting responsibly and the local awareness raising and signage has been a success.
The sheep will stay on site for a few more months and hopefully continue their good work and we can get a fair idea of what their impact has been so far. Next year, we can act on our lessons learned and improve our methodology.
This is a multiple year project and one of the outputs will be to develop practical and useful advice to empower other land managers to use sheep – or other livestock – as a means of controlling invasive plants on their land. This will include public open days and site visits etc. as well as written findings.
This project truly is a work of collaboration and the Scottish Invasive Species Initiative would like to thank all the partners for their continuing support and input; the Gordon family of Kirkside Farm, The University of Aberdeen, the Deveron, Bogie and Isla Rivers Charitable Trust, the Macduff Distillery and the local people of Macduff.
Cally has been volunteering with the Scottish Invasive Species Initiative (SISI) for a year and shares her experiences with us of her time volunteering so far.
I was studying applied science when Karen from Scottish Invasive Species Initiative (SISI) came along to the college to give us a presentation explaining her role as project officer, which included, conservation work and reaching out to the community to help identify and tackle the problems we are facing with invasive species along our water courses. As Karen went on to explain in more detail about the activities her role involves the entire room turned to focus on me. Everyone who knows me understands how I love to be outside investigating and seeking out anything out of the ordinary. Hearing about her talk about her work and the benefits to the native wildlife and biodiversity, really had me interested. That was what I wanted to do. I got in touch via email immediately with Karen who works within the Deveron, Bogie and Isla rivers catchment area, and with James who works within the Lossie, Nairn and Findhorn rivers catchment. They both put me to work straight away…
My first volunteering expedition, and I call it an expedition because it was exactly that. Karen took me to a stretch of the river Ugie in Aberdeenshire which to say the least was varied terrain. We were surveying the presence and amount of the invasive non-native Himalayan Balsam plant. Along our route we encountered some overgrown bramble, nettles and some boggy areas which I almost lost a wellie in. I fell to the ground many times, which was mostly due to my lack of balance and finesse. However, it was a superb experience and we had some serious fun along the way. There was an area of intense overgrowth so we decided to it would be easier to cross the river onto the other side. No-one fell in, which was a real achievement, although we made sure that we were perfectly safe by choosing a relatively low and slow running area to cross, but the wellies did fill up. Fortunately, it was a scorcher of a day and during our lunch break I was able to dry my socks out. I think we must’ve walked about two and a half miles that day, and did what we set out to do, survey complete. I wasn’t sure if Karen would take me back out with her again or if she went away thinking I was a bit of a liability, but thankfully we have tackled the rivers many times since, mostly controlling Giant hogweed.
James also got in touch and offered me my very own Mink
Monitoring Raft, which I was delighted about. He came and explained how it all
works and gave me information about what I could look out for and left me to it.
It’s always very exciting to go and check a raft for any signs of wildlife. I
have had several prints but none of them mink, which can be a positive sign. I
have seen otters down by the river while I have been down checking my raft,
which is always nice to see. Since James gave me my first raft, he offered me a
second raft along a different stretch of river which again I was happy to agree
to. When I go to the river to check on my rafts, I usually spend a few hours
there just taking in the surroundings and taking that time to relax. I noticed
other signs of wildlife presence, including footprints and padded down plants,
holes in the embankments and feathers, so I bought myself a trail camera. Since
I have set it up, I have had footage of roe deer, badgers, mice, pheasants and lots
of various native birds.
I have been learning as I have been going along from the project staff, I have attended events including Wild about Aden, which is a family event within a country setting for all ages. We set up an information stall for SISI which was a public engagement role. Spending a couple of days engaging with the public, educating them about the invasive non-native species and their effects improved my confidence and I was surprised at how much I had learned in the short time I had been working with them. SISI has also given me the opportunity to attend courses, including the pesticide spraying course where I gained my certification which now enables me to use pesticides to treat invasive plants.
There have been so many opportunities in my first year working
as a volunteer with SISI that I would never have expected, which I am very
grateful for. It has been very rewarding seeing the impact we are making on embankments
of the rivers and streams, and successfully handing over the opportunity and
support to landowners to take the reins and continue.
I have been out many times now with Karen, James and Al on
long days of Giant Hogweed control and my fitness levels have improved
remarkably. I have noticed that my breathing has improved and my balance too. I
can carry weights of 15 litres on my back and walk for many miles. But most of
all, my mood is always on top form when I am out and about with them. They are
a super team to work with.
I have a lot of exciting times ahead with SISI and a lot more conservation work to do which I am looking forward to. Thanks SISI.
Guest Blog – Gill Hatcher, Saving Scotland’s Red Squirrel Project, May 2019
It’s ‘Invasive Species Week’: an opportunity to talk about
the threats non-native species can pose to our special wild places, our natural
heritage, and global biodiversity; as well as what people can do to help. But
often the first challenge in raising awareness is simply explaining what ‘invasive’
means. It’s not a household term, and it can be a complex – and sometimes
controversial – subject to discuss.
Perhaps none more so than the grey squirrel. The grey squirrel
is equally one of the most familiar examples of an invasive species in
Scotland, and the most clouded in confusion, misinformation and emotion.
The eastern grey squirrel is a North American species that
was first brought to Britain to decorate the gardens of Victorian stately
homes. With an abundance of food and fewer competitors to contend with, they
quickly settled in their new surroundings and began to spread across the
As the only squirrel species native to the UK, red squirrels
struggle to compete with grey squirrels for food and living space. Some grey
squirrels also carry squirrelpox, a virus that doesn’t harm them but is deadly
to reds. As grey squirrels have moved into an area, reds have gradually
disappeared; and today greys have completely replaced reds throughout most of
England and Wales, as well as Scotland’s Central Belt and the city of Aberdeen.
In many of these places grey squirrels have been present for
well over a hundred years, with the native red squirrels barely a distant
memory. So for many people in the UK today, grey squirrels are the norm. In
cities and towns, they are often one of the few wild mammals people come into
regular contact with, providing a rare connection with nature. It’s not
surprising that many don’t realise that grey squirrels are not native, that red
squirrels were once widespread or even that the two are different species of
squirrel. Before we can even begin to explain the term ‘invasive species’, we often
have to start with the basics if we want widespread understanding and support
for red squirrel conservation action in Scotland.
While raising awareness of the threat from invasive grey
squirrels, it’s also important to emphasise that there are still many places in
Scotland where red squirrels are thriving. Home to 75% of the remaining UK
population, there are healthy populations in the Highlands, the Central
Lowlands and parts of South Scotland. Red squirrels are under threat, but they
are still very much worth saving.
Saving Scotland’s Red Squirrels is a partnership project led
by the Scottish Wildlife Trust. Established in 2009, its aim is to protect
Scotland’s red squirrels by combating the spread of grey squirrels. With the
help of landowners and volunteers, grey squirrels are being controlled through
live trapping and humane dispatch in the areas where this action will have a
positive impact on core red squirrel populations.
In 2017 the project was awarded a £2.46 million National
Lottery Heritage Fund grant to begin a new phase called ‘Developing Community
Action’. Recognising that landscape-scale community involvement will be the key
to the long-term protection of Scotland’s red squirrels, the project is now
focussing on building a strong network of local volunteers, providing them with
the skills and resources they need to carry out red squirrel conservation work in
priority areas. The first step is community engagement: building a basic
understanding of why red squirrels need our help and why, at this time, control
of grey squirrels is the only way to ensure red squirrels will continue to have
a home here.
One way to start this conversation, and one of the simplest
ways people can help the project is by reporting red and grey squirrel sightings.
The sightings map contributes to our understanding of squirrel distribution
across Scotland, and it could act as a stepping stone to getting more involved.
There are lots of ways to take action for your local red squirrels, from survey
work, to grey squirrel control, to helping spread awareness by volunteering at

This year Invasive Species Week is being held from 13-17 May, the purpose of the week is to raise awareness across Great Britain about invasive species and their impacts.
Being a project all about invasive species, here at the Scottish Invasive Species Initiative, we’re quite excited about having a whole week of all things invasive and we’d love everyone to share in our enthusiasm and get involved!
There are lots of ways to get involved in Invasive Species Week, you can join in with a practical hands-on volunteering session to remove invasive plants, adopt a mink raft, go on a guided walk, drop in on one of the pop-up stalls or follow our social media posts throughout the week to learn more about invasive species and what you can do to make a difference.
Here’s a list of events we and our partners are running during the week – click on each event to follow the link to our website where there are more details.
If you can’t make any of the events, don’t worry you can still stay involved in Invasive Species Week! Follow us on social media on Facebook, Twitter and Instagram, we’ll be posting lots of information all week about invasive species, what to look out for, what to do about them, alien facts, what things everyone can do to help, gardening tips etc.
Or why not take the initiative and do your bit in your local area? Learn how to identify Himalayan balsam, (download an ID guide here), an invasive plant found growing widely along river banks and head out with a friend (always advisable not to work alone near a river) and go and pull some up! It has a really shallow root system so its easy to pull by hand, put it in a pile away from a path to compost or hang it roots up from a fence/tree (so it doesn’t re-root). It might still be quite small at this time of year but it’s great to pull it and remove it before it flowers and spreads more seeds.
Don’t forget to share how you’ve got involved in Invasive Species Week with us on social media – tag us into your posts and let us see what you’ve been up to!
Invasive Species Week is coordinated by the GB Non Native Species Secretariat. Read more about the week here.
We’d like to kick off by telling you a bit about the Scottish Invasive Species Initiative (SISI). We are a 4 year project (2017-2021) which aims to engage local people, volunteers, groups and communities with the control and management of Invasive Non-Native Species (sometimes referred to as INNS).
We are a partnership project; Scottish Natural Heritage (SNH) is our lead partner, and our other partners are 10 fishery trust/boards and the University of Aberdeen. Our funding is from The National Lottery Heritage Fund and SNH, with in-kind support from our fantastic volunteers.
Our project area is vast, covering nearly 30,000 km2 (which is an area larger than the country of Wales) so we are really working at a landscape scale. Our area includes Highland & Eastern Perthshire, Angus, Aberdeenshire, Moray and Highland.
We have a team project staff employed by the Scottish Invasive Species Initiative and work is also delivered by local staff from the fishery trusts/boards.
We are dealing with a specific list of Invasive Non-Native Species (INNS) – Giant hogweed, Japanese Knotweed, Himalayan balsam, American skunk cabbage, White buttebur and the American mink. All these plants and animals are causing damage to our native species, our countryside or to the way we live, so removing them will provide benefits to our native wildlife and local communities.
What we aim to do is to work with local people and local groups to support their involvement in invasive species control work. This includes provision of equipment, training opportunities and co-ordination of resources to build the capacity and skills within the communities, with the ambition that when our project finishes there will be enthused, inspired, qualified and equipped people out there to continue control work, giving a legacy and sustainability to our project.
We will also be working hard to raise awareness about invasive species and their impacts, through working in schools, producing films, going to local shows and talking to local groups, as we want more people to be engaged with, and care for, their local river environment.
