Foreword

“We have come to the end of Capturing our Coast and what a journey it has been. We have made new friends, and explored new parts of our coastline. Both scientists and volunteers have challenged themselves and pushed the boundaries of what it is to do science, together, working in new ways. Marine citizen science is one way we can share the responsibility of making a difference and work towards healthier, biologically diverse seas. Our power lies in our numbers and co-operative working in a systematic way. Each Capturing our Coast member who took a record or a measurement has helped build up to an impressive wealth of information. Never underestimate the importance and value of your contribution. The information you have shared is being put to use right now, and will remain available for use by scientists, conservation groups and environmental consultants for decades to come. Coming together and collecting data systematically is a powerful tool that aids our understanding of species’ responses to environmental change, the ways in which coasts are impacted, and when recovery occurs. One goal for Capturing our Coast was to explore the degree to which you, the great UK public, wanted to participate in scientific research. The research and learning, for both volunteer and professional scientist, centred on finding out what worked. You have astounded us in your perseverance, your skilled eye, and your willingness to share and engage. Your questioning of how we work as professional scientists has made us reflect and be more critical of what we do. The potential of marine citizen science is enormous, but for it to be most influential moving forward, the challenges of working in this way together must be acknowledged. So, not only have you added to knowledge of distribution and ecology of marine species, but you have extended understanding of how marine scientists and marine citizen scientists can best work together. It is our hope that marine citizen science will become accepted by the professional scientific community, decision makers, policy makers and governments as ‘the norm’ - a usual and legitimate way of investigating and building knowledge. If this is achieved, what we can accomplish together is unlimited. Seeing what we have achieved here together in Capturing our Coast awakens great optimism for the future of marine conservation and for our fantastic UK seas. Our data will enter the pool of evidence that is used to leverage support and political change for environmental benefit.”

“Never underestimate the importance and value of your contribution.”

the story so far...

Data from Capturing our Coast species package surveys up to

the end of July 2018 are being verified and analysed. They will be

uploaded to the National Biodiversity Network and available for

use by environmental consultants or scientists as a baseline

against which to monitor change.

One use of the data from your species’ surveys is to explore responses to environmental change. This graph shows the species recorded by volunteers, mapped against the average temperature at those locations and at what temperature each organism was found (within their known temperature tolerance range). We can identify which species are closest to the edge of their thermal tolerance, and therefore are most at risk if a 0.5 degree Celsius change in temperature occurs. This demonstrates the UK’s unique combination of warm and cold water species, which exist together due to our latitude and the warming effect of the currents that feed our seas.

National Results

Species package surveys have been conducted along most stretches of the UK coastline, with the only notable exceptions being areas where rocky shores are sparse, such as East Anglia. Over twenty scientific papers are planned or being written utilising data from the species package surveys and from the special investigation projects. We hope that numerous other scientific studies and publications will be made possible by the existence and availability of the data you have collected!

Why carry on collecting data? A view from the scientists

“Capturing our Coast has created a unique picture of the patterns of life on our rocky shores. This has been hugely useful for understanding how our coasts might change with our changing climate in the face of heatwaves, storms, and a generally warming world. Where the data becomes incredibly valuable is as a baseline against which we can judge the effects of such events as they happen. Has the hot summer of 2018 had an impact on rocky shore species, for example? While the first CoCoast project will end in October 2018, we welcome more CoCoast data from our network of trained volunteers. There will not be the ongoing support that we were able to offer during the project but, as highly trained surveyors, you will be able to upload results to the website for the period leading up to the possible next phase of CoCoast. Practically, surveys of the same sites every year at the same time would be most useful. We will review these data every few months and use them to answer those questions about the continuing changes on our seashores.” Professor Mike Burrows, SAMS, Scotland

Fabulous finds in the North East

The first ever record of a stalked jellyfish at Boulmer was made in April 2016. Volunteers also spotted sperm puddles at Cresswell as well as over 120 species on a Bioblitz at the same site this June. Species spotted here included the worm pipefish ( Nerophis lumbriciformis ) and the invasive orange-tipped sea squirt ( Corella eumyota ).

Wonderful Wine and Science

Two of the most popular Wine and Science nights in the North East were held in early 2018 with a whopping 38 attendees at both events! Dr Thomas Linley, who was part of the research team that discovered the world’s deepest recorded fish, fascinated us with his talk ‘Deeper than Deep: tales of science in the deepest reaches of our oceans’, whilst Professor John Bythell gave us a plethora of ‘Fascinating facts about sea anemones to entertain people at parties’. Thank you to all the speakers that have given their time to inspire and share their work with our volunteers.

Boat trip in the Solent

In August 2017 we took a group of 10 volunteers out on a boat in Langstone Harbour and onto the research pontoon. We had our eyes peeled and were lucky enough to see two local harbour seals, as well as a lot of marine life on the pontoon itself, including some blue velvet swimming crabs.

Beachy Head East:

Marine Conservation Zone

In early 2018, Portsmouth volunteers started to survey a rocky headland site that is part of Beachy Head East. It is a 193 km^2 area of shore stretching from Beachy Head Cliffs to Hastings Pier and is being considered for Marine Conservation Zone status. This site is included in proposals to create a “blue belt” of protected areas around the British Isles. All data collected here are being given to the decision making bodies for this proposal, further contributing to marine conservation in the UK. We have found lots of amazing marine life here from topshells and periwinkles to snakelocks and beadlet anemones, even a strawberry anemone too!

Fantastic finds at Looe

During a survey at Looe, the team and volunteers were treated to a very special sight: hundreds of mating Sea Hares (Aplysia punctata) in shallow pools that had been exposed on a great spring tide! Strings of eggs resembling pink silly string noodles were strewn everywhere. We couldn’t believe how lucky we were to see so many large specimens, between 15-20 cm each!

Capturing our Coast Southwest citizen scientists have completed quadrat surveys and special investigations within Skerries Bank and Surrounds, Tamar Estuary, Whitsand and Looe Bay, Padstow Bay and Surrounds, Mounts Bay, Land’s End, Newquay and the Gannel, Hartland Point to Tintagel and Bideford to Foreland Point Marine Conservation Sites. CoCoast staff were involved in the designation process for several of these MCZs.

Seasonal Surveys

For Christmas 2017, the Southwest team ran three BioBlitzes in just five days across Cornwall and Devon. There was fantastic attendance of volunteers who all got involved with some fun ‘search and identify’ tasks, whilst also helping us record data for the Marine Invaders, Wading Birds and General Quadrat surveys. Those attending our Trevellas Cove BioBlitz were treated to a sighting of a stalked jellyfish! Each event was a great success and loads of fun regardless of some bitter weather… hot chocolates in the local pub certainly hit the spot at the end of a hard day’s work!

Fantastic finds in Bangor

Volunteers found this gorgeous stalked jellyfish (above) at a field support event at Porth Cwyfan. Their funnel-shaped bodies grow up to 5cm in height, and have eight webbed arms.

Shore in the spotlight: Port Cwyfan

Porth Cwyfan on Anglesey’s west coast has provided a perfect location for multiple Capturing our Coast investigations including: Race to Recovery, Seaweed vs. Limpets, Microlives, Species Packages, Marine Invaders and Beach Babies! Renowned as the location of St Cwyfan’s Church, the Church in the Sea, this beautiful bay was home to some of our most fantastic finds including a stalked jellyfish and a common octopus!

Extended reach

With over 20 events throughout the years, the Wine and Science series has been a great success, and enjoyed by hundreds of volunteers all over Scotland (and the world!) due to the live-streaming of the talks. Together, we’ve seen penguins in the Antarctic, watched marine mammal autopsies and discovered what barnacles can tell us about climate change. Thanks to all our inspiring speakers, and everyone who came along.

Capturing our Coast Scotland has been a fantastic example of partnership working, with support from organisations such as the Hebridean Whale and Dolphin Trust, Scottish Wildlife Trust, RSPB, Scottish Seabird Centre, local coastal partnerships and more community groups than it is possible to name here.

Success in Scotland!

Capturing our Coast has been a success due to the drive, enthusiasm and good humour of all the volunteers in Scotland. They have walked, climbed, driven, canoed and sailed to shores all across Scotland, in blazing sun and driving rain, all in the name of science. Particular highlights shared by some volunteers include finding sunstars on a cloudy west coast day, discovering Oban Bay is secretly full of painted topshells, and getting a view into the hidden squishy world of jellyfish, worms, bryozoans and sea slugs during kelp surveys!

Invasive species are one of the top threats to

global biodiversity. Globalisation of maritime

and marine activities has resulted in increased

rates of introduction and establishment

of non-native and invasive coastal marine

species through increased maritime traffic,

unintentional escapes of species deliberately

introduced for aquaculture, and introductions

through hitchhiking with imported species.

The effects of individual species can be

complex, with both positive and negative

potential impacts.

Marine Invaders is a Capturing our Coast initiative designed to record the abundance of 16 coastal invasive species, for Horizon Scanning (not yet found in the UK), or monitoring the distribution and spread of currently introduced or established species. Species were selected to align with policy requirements, with consultation from UK conservation bodies from the outset. The species surveyed are of interest for the Marine Strategy Framework Directive, which aims to ensure healthy, productive, safe and biologically diverse seas in Europe.

Using the power of mass-scale participation from Citizen Scientists around the UK and Channel Islands, Marine Invaders has been hugely successful to date. Over 2,000 records have been collected in less than one year, with more than 100 volunteer surveyors participating in this work. Marine Invaders has collected 162 confirmed Non Indigenous Species records. The three most commonly found species to date are Sargassum muticum (Japanese Wireweed): 75 records, Crassostrea angulata/Magallana gigas (the Portuguese Oyster and Pacific Oyster): 30 records and Undaria pinnatifida (Wakame): 21 records. The first record of the Asian kelp Undaria pinnatifida (Wakame) in the UK was in the Solent in 1994. Since then, this species has been spreading around the coastline of southern England. During Marine Invaders searches performed in south Wales in August 2018, the first record of this species within the Skomer Marine Conservation Zone was collected on Skomer Island. This was shortly followed by Marine Invaders surveys contributing the first record of this species on nearby Skokholm Island. Both islands fall within the Skomer, Skokholm and the Seas off Pembrokeshire/Sgomer, Sgogwm a Moroedd Penfro Special Protection Area.

New records, such as those collected by Marine Invaders, are an important contribution to scientific understanding and the management of Non Indigenous Species. To date Marine Invaders has been very successful, with data collected around the UK and Channel Islands. Thanks to an excellent effort from a fantastic group of surveyors. Marine Invaders will continue to run after the end of the CoCoast programme. Please carry on surveying and submitting your records to www.capturingourcoast.co.uk/specific-information/marine-invaders

surveyed

1,817 quadrats were surveyed over 2 years at 8 monitoring events - that is the equivalent of almost 2 tennis courts. CoCoast volunteers and staff measured over 620 metres of canopy seaweed – that is twice the height of the Shard!

Huge thanks to all those CoCoast citizen

scientists who took part in the experiment

and worked with their local CoCoast teams to

generate all of the data! With your help, we

have gained more insight into how rocky shore

communities recover from disturbance!

The figures below shows the percentage cover (a) and size (b) of brown algae at Porth Cwyfan, North Wales. The orange line are the sites that were cleared at the start of the experiment. The blue line are the sites that were not cleared. The horizontal line shows the average abundance across sites, the vertical lines how much variation there was in abundance across sites (standard error).

monitoring events

With the number of storms hitting the UK each

year increasing, we wanted to understand

how rocky shore communities across the UK

recover from storm-like disturbances. We were

particularly interested in whether there were

latitudal differences position North to South

in the recovery of rocky shore communities,

or whether local environmental context, such

as how exposed the shore is to wave action, or

the geology of the shore, were more important

in determining the pace of recovery.

Five CoCoast hubs around the UK took part in an experiment across 14 shores. At the start of the experiment, we simulated a storm-like disturbance,

by clearing small sites of shore of seaweed. On each shore, we also had a set of sites that we did not clear, so we could compare the recovery against these sites. 63 CoCoast volunteers, alongside CoCoast staff, monitored these sites every three months, recording percentage cover of different groups of algae, such as canopy, turf, green and fucoid algae, as well as the maximum length of the canopy algae. We are still in the process of analysing the data, but the initial results that show there is a lot of variation in the rate of recovery from disturbance across regions and shores, rather than clear latitudinal patterns in recovery. This suggests that local environmental conditions, such as the amount of wave exposure or type of rock, are important in determining recovery.

Capturing our Coast has created a

community of skilled and passionate

volunteers, training over 2,800 volunteers in

scientific survey techniques, and engaging

hundreds more through simple data

collection campaigns such as Spermwatch

and Marine Invaders. The project is nationally

well regarded, including within the scientific

community.

Increased scientific knowledge

The 240,000 data points collected across 1, locations across the UK from the species package surveys create an immense dataset that has taken thousands of hours to collect. This level of data collection would be impossible for scientists to collect without the help of volunteers. The data set will be openly available for anyone to use, as will the research protocols and training materials. Let’s not forget the data collected for each of the Special Investigations. Over twenty scientific publications are planned over the next year, on subjects from biodiversity on artificial substrates, to species interactions, invasive species and citizen science, and how climate change is affecting rocky shore biodiversity.

Looking forward

Over 2,800 volunteers have learnt about threats to the marine environment and been provided with opportunities to get involved in marine conservation and research. A further 4.7 million people have been reached through Capturing our Coast media exposure, stories, tweets and publicity.

Health and well-being benefits

Capturing our Coast has brought people closer to nature and connects them with the ocean and their local coastline. Participants spend more time outside and reported feeling like they lead a healthier lifestyle.

Education and learning benefits

Volunteers have received training and learnt scientific survey techniques. Others developed skills and knowledge through self-led learning activities and by using resources.

Enhanced advocacy and attitude

Through their training and involvement, volunteers feel a sense of ownership over their coast and gain a greater awareness, understanding and appreciation of the marine environment, and the need to protect it. This ultimately encourages us all to feel a sense of responsibility for the future of our coast and the wildlife that depends on it, which we are able to contribute to, and act upon. Opportunities to act, such as participating in the Great British Beach Clean, were provided by Capturing our Coast hubs.

Policy and management contribution

The project has informed invasive species management in the UK and we are in discussions regarding the use of Capturing our Coast protocols and Marine Invaders methods in monitoring programmes for Ramsar designated sites in Jersey and Guernsey. Out of 57 currently designated Marine Conservation Zones (MCZs) and NC Marine Protected Areas, Capturing our Coast surveys have been located within 23 of them, as well as in sites that are currently proposed for potential designation as MCZs, where data is given directly to the decision-makers. We reported the findings of the national project at international scientific conferences, and at a variety of workshops and meetings, including in discussions with the Environment Agency, Natural England and Cefas. We have demonstrated that citizen science can generate evidence and discussion that has the power to change coastal management policy or make recommendations towards conservation action.

Positive environmental impact

Through action taken on the data collected, and development of future projects following outputs from Capturing our Coast, the project has the potential to contribute to enhanced biodiversity, generate pro-environmental behaviours and inform mitigation and adaptation to climate change.

Impacts will continue to come out of the project for years to come, and we will endeavour to

share news of these to the Capturing our Coast community whenever we can.

LOOKING FORWARD FREQUENTLY ASKED QUESTIONS

“We are incredibly impressed with the enthusiasm and contributions of our volunteer community.

Your skill and conservation capacity as a national community is hugely valued and we don’t want

to lose this. We intend to build on our collective successes to forge ahead with a second phase of

this project, which for purposes here, we refer to as ‘CoCoast 2’. We hope you will continue to

work with us and that your experience so far has been positive.

‘CoCoast 2’ will most certainly retain many elements that are similar to the original project. We know we share the same goals of working towards greater understanding of how marine species interact, what affects where they occur on our coasts, and how they are negatively impacted. So, continued learning about marine life and surveying together will be a core element of the next phase. Certain tasks and questions require longer term datasets to fully explore the issues, and you will see some familiar topics reappearing, such as addressing the spread of invasive species and monitoring particular shores to examine closely how breeding is affected by environmental change. We also plan to run some exciting, short-term experiments where the results can be revealed after 4-8 weeks: our ‘Short Sharp Shocks of Science’. We hope you will agree that all of this is very worthy and inspiring, but we also want to be really innovative and move beyond what we achieved in Capturing our Coast. Citizen science is evolving; it is becoming remarkable in the way it empowers people, and increasingly volunteers are shaping the projects and the scientific issues that are being addressed. We want you, our Capturing our Coast community, to be part of this movement of ‘co-enquiry’ and work with us to shape the structure of the next project. This may sound daunting, but we believe that you have the valuable insights and ideas to progress UK marine conservation and further marine research. Together we will build CoCoast 2 communities around the UK, where volunteers have much greater say over data collection priorities. As I am sure you will appreciate, this all requires funding. And sourcing funding requires development and time. We will collate evidence, not only to convince funders that CoCoast 2 is valuable, but to ensure for ourselves that we get the structure right. To this end, over the next year we will be researching perspectives from volunteers and relevant organisations. We will be holding workshops to brainstorm ways of working, and to find out what volunteers really want. We will update all on our communication database about our progress in autumn 2019. There is a real opportunity here to develop something truly innovative, that not only captures important information with immediate and direct benefits for the marine environment, but that develops a new model of collaborative working between professional scientists and marine citizen scientists. The longer term ramifications for marine conservation could be really significant. We hope that you will feel, as we do, that the wait will be worth it.”

Dr Jane Delany, Director of the Dove Marine Laboratory, August 2018

What are we doing with the data?

Our team will continue to analyse the data. Our findings will be shared with other researchers nationally and internationally, as well as with other organisations working in marine science and conservation.

Will data collection will continue?

While the project officially ends in October 2018, we will continue to collect species package data from our network of trained volunteers.

Will any Capturing our Coast projects be continuing?

Enthusiastic volunteers can continue to engage in scientific activities, even beyond the project end. Projects still running include Beach Babies, Seaweeds vs. Limpets, Microlives, Zooniverse, CoastXplore, Marine Invaders and Wader Birds.

Want to get involved in other projects?

Many of the Capturing our Coast partners run other citizen science or volunteering projects that you might be interested in. From the Great British Beach Clean and the Big Seaweed Search (MCS), to FreshWater Watch (Earthwatch) and The Shore Thing, Sealife Surveys and annual Bioblitzes with (MBA).
