The last day of the BES/Sfé meeting was in the mood of celebration, so a session dedicated to celebrating citizen science was in place. My notes from first day and the second day are in previous posts. These notes are long…
Before the session, in a symposium on tree health, Michael Pocock (CEH) presented ‘Monitoring to assess the impacts of tree diseases: integrating citizen science with professional monitoring‘. Ash die-back is important, and in the rest of Europe, (e.g. Denmark, Lithuania or Poland) there are losses of 60-90% but there was very little work done on monitoring the biodiversity impact of the disease in general. There is a clear lack of knowledge on the impacts on biodiversity in general – how suitable are existing surveys, how they can enhance? In a work that he done with Shelley Hinsley they reviewed 79 relevant studies, from volunteers to national professional survey and local studies. They tried to answer questions such as: What kind of things can be impacted? they identified all sort of impacts – trophic networks, structural, cascading, and ecosystem functions. They looked at different receptors in different contexts – from animals and plants on the receptors, to where they are located as context – woodland, or hedgerow. They found that woods are fairly well monitored, but how much professionals will continue to monitor it with budget cuts is an issue. Ecosystem function is very poorly monitored. The recommendations of the report are that current ongoing activities are suitable and maybe should be modified a bit to make them better (e.g. asking another question in a survey) – they didn’t recommend brand new surveys. The report is available here . If we want future proof monitoring that deal with the range of tree disease and other issues – we need a better ‘spine’ of monitoring work (in the report on page 5), but improve the integration of information and synthesis between survey. Co-location of monitoring site can be great, but actually, there are specific reasons for the locations of places in each scheme so it’s not easy to do so. In addition, volunteers based monitoring require investment in maintenance. He completed his talk with more general citizen science issue that we can learn from this work – the national plant monitoring scheme is to be launched in 2015, and there are some specific focused on lichens and other issues that require specialist knowledge in survey programmes like Splash. Mass participation is useful in some cases, but there is an issue how much recording effort is quantified – there is a big differentiation in ability to monitor species across the country and the ability of participants to record information. The retention of volunteers in mass projects is an issue – only 10% continue after a year. In enthusiasts recruitment you get higher numbers 20% that continue to be involved. The most exciting opportunity that he see is in hypothesis-led citizen science, like the Concker Tree Science project.
The ‘Celebrating Citizen Science’ session was at the final group of sessions of the conference, but was very well attended. Chaired by Michael Pocock, who, together with Helen Roy, runs the BES Citizen Science SIG.
Romain Julliard (Muséum national d’Histoire naturelle) provided an overview of citizen science activities in France in his talk ‘Biodiversity monitoring through citizen science: a case study from France’. The starting statement was that unskilled amateurs from the general public can provide good information. The museum have a role in monitoring biodiversity at the national – common species are good indicators, the appropriate for studying global changes and the general public is interested in ‘ordinary Nature’ – the things that we see every day. Scientists alone cannot monitor biodiversity over a big space such as a country, so citizens can help to collect data on a country scale and they are already spread across the country. The trade-offs of using citizens as observers include skills vs. numbers of participants – there are only few experts and enthusiasts. Another issue is sampling design: are you aiming for representativeness of where people are or do you send observers to specific locations to do the survey. There is a need for a simple protocol for volunteers. Much simpler than procedures in a research station professionals. They started with French Bird Breeding Survey in coordination with NGOs like LPO and others – with over 2000 squared that are being observed since 1989 and over 1000 provide long-term monitoring. Now they have skilled amateur schemes – monitoring bats, butterflies and much more. They started their programmes in 2005 with butterfly programme, pollinating insect survey from photographs (Spipoll) in 2010 and garden bird watch in 2012 among others – new programmes especially in the past 5 years . Spipoll provides a good example of the work that they are doing. Pollinators are useful to raise awareness and explain multi-factor pressures on the environment. The are many sampling sites and thousands of flowers dwelling insects in France. They Spipoll protocol starts with 20 minutes ‘safari-photo’ which mean that you select a flower and take photos of each visiting insects. Second step is to select the best single photo for each insect that was sampled. Third step to name each insect from 630 possibilities – and they create an online tool that helps the identification. Final step – share the collection with other people. Once photos are shared, there are plenty of comments from other participants. The participants are encouraged to help each other observations and there is also expert participation in identification. By now, they have over 600 regular participants, 18,000 collections, and 155,000 photos. Many of the participants are not experts in biological recording but have interest in photography. in terms of data quality they looked for precision, repeatability (how close the process was to the protocol). The social control help in improving quality, and the representativeness can be done in explicit sampling design but also in post-study statistical analysis. Beginners tend not to follow the protocol, but other people are helping them and within 3-4 iterations, people are learning the protocol and follow it.
Helen Roy (CEH) talk (with Harding, Preston, Pocock and Roy) ‘Celebrating 50 years of the Biological Records Centre‘. She gave some key achievements that also appear in a booklet on the 50 years of BRC. The BRC was established in the 1960s to support volunteer recording in the UK – they have now a team of 14 permanent staff. 85 different recording schemes from flee to bees, ladybirds and many other groups. Recording schemes are running by volunteers coordinators – so support is provided by printing newsletters, publishing atlases, etc. They cover a lot of taxa – plants and animals. Over the decades, they have long-term datasets which lead to distribution atlases. Over 80m records. UK biodiversity indicators for the UK government are collected by volunteers and used in decision-making – they are now growing from 24 indicators to include pollinators and other elements. Another area of importance is biological invasions as it cost the UK over 12 billion EUR a year – and not only to look at existing species but also to look forward about the threats – and because volunteers are so knowledgeable, they contributed to horizon scanning work. Work on surveillance and monitoring extend to the general public with publicity – this way they for example got information that Raccoons are being seen in the UK. Another important aspect of BRC data is the ability to use it to understand the decline of native species – for example understanding changes in native ladybird species. Finally, the information is very important in climate change scenarios and use the information about habitats can help in interpreting data and predict future directions.
In the work of the BRC, technology is becoming an important driver – they share it through the NBN gateway, and also apps and websites such as iSpot, iRecord and other bits are helping in developing new sources of information. In summary, to deal with environmental challenges that we’re currently facing cannot be done without this information and interpretation by volunteers. She finished with a big thank you to the many volunteers recorders.
In ‘How to use data generated by general public of a citizen science program for conservation purpose’ Nathalie Machon (Muséum national d’Histoire naturelle) explored another successful French study. They see importance in preserving biodiversity in cities – regulate city climate, dealing with air pollution, contributing to public health etc. In cities, most of the biodiversity is in parks and gardens but the urban matrix is permeable to many animal species such as pollinators. The potential of connection between green spaces is important to create a network in the city. How the structure and management of cities influence biodiversity? was a research question that the programme ‘sauvages de ma rue‘ was set to explore. Since 2011 participants share information about wild-flowers in their own streets. When the programme started, they wanted people to learn to recognise species near them and collect information about the distribution of plants in their area . The protocol is fairly simple – identify street, collect data about plants in different habitats (cracks, walls) and send the information. They created a guide to help people identify species and also created a smartphone app. Usually people start by providing data about their street, but the programme grew and now they have groups and organisations that deal with naturalist activity and they send a lot of data from many streets in the same place. The organisations can be about sustainability, schools university or nature enthusiasts. They receives 40,660 data points by 2014 which provided the basis for her analysis.
After correction, they had reliable 20,000 data points in 38 cities and 2500 pavements – they check the richness of pavements and the obvious factor is the length (of course) but in about 100m there is a levelling in terms of species. They found that the structure of the street is important – if it is only in cracks, there are less species. The richness is not correlated to population density, but in large urban area (Paris) there is a significant decline toward the centre. They also look at pollination – and found that the number of pollinators is correlated to the human density of the city but not correlated to the distance to the centre of the city, apart from the case in Paris. They also seen increase with habitat types in a pavement. In terms of cities, they discovered that Nantes, Brest and Angers are doing well. However, they are aware that there is an observer effect on the results. Observers were shown to be good as botanists. In summary, they’ve learned that insect pollinated species are easy to recognise and it’s possible to carry out such studies effectively with lightly trained volunteers.
Anne-Caroline Prévot (CESCO – Muséum nationa l’Histoire Naturelle) reviewed her research on ‘Short and long-term individual consequences of participation to citizen-science projects’ in an approach that combines environmental psychology and ecology. There is growing concern on separation between people and nature: extinction of experience (Pyle 2003, Miller 2005) or environmental generational amnesia (Kahn 2002). There is a need engagement of majority of citizens to change their approach. In the psychology field , there is Stern influential piece from 2000 on environmentally significant behaviour, linking individual to different aspects of pro-environmental behaviour. Identifying social and personal factors . On the other hand, in citizen science programme there are multiple goals – contribute to ecological science ; educate people to acquire knowledge on biodiversity; etc. There is also potential of reconnection to nature – so the question that she addressed “Did citizen science changed biodiversity representation and knowledge? environmental values? pratcial knowledge? skills?” (all these are based on Stern framework). She looked at the butterfly collection programme and interview 30 regular volunteers who participate every year – They found that they were confident in science, and they discovered new aspects of biodiversity through participation and change their gardening practices. This can change representation but they were environmentally concern to start with. There was no issue of group identity with this group of volunteers. The second study looked at a programme at school (vigienature école) with 400 pupils from 29 classes in 11-13 age group. They use a questionnaire to understand environmental value and other activities outside schools. In addition, they asked the children to draw an urban garden. Each drawing was analysed for natural elements, built elements and humans. Participation in nature monitoring showed higher presence of nature in drawing but no difference in environmental values. They think that it probably changed representation, but not values, there was no assessment of skills and there was some aspect of group social identity. In summary citizen science initative may change knwoeldge and attitdue of volunteers but this require attention and more evaluation.
Rachel Pateman (SEI) presented the an MSc project carried out by Sian Lomax under the supervision of Sarah West (SEI) on ‘A critical assessment of a citizen science project‘. It’s an assessment of the science and impact of participants from the OPAL Soil and Earthworm Survey. Aims of citizen science are to answer scientific questions, but also to provide benefit to participants – learning, fun, change behaviours, or information for lobbying on behalf of nature. The challenges are how to find inclusive methods and have good quality data. The participants aim are not simple – there is not simple link between participation and pro-environmental behaviour. The way to deal with that is to evaluate and reflect critically during the development of a citizen science project, and inform the design process (this remind me a lot of Amy Fowler’s thesis, also about OPAL). The OPAL programme is aimed to be educational, change of lifestyle and inspire new generation of environmentalists and greater understanding of the environment. Sian evaluate the soil and earthworm survey which are usually run with an instructor (community scientist) but also can be done by ordering a self obtained pack. The methods – dig a pit, identify worms, and identify properties of the soil and then submit the inforamtion. The aim is that participants wil learn about soil properties and get interested in environmental issues. Sian recruited 87 participants from ages 5 to 60 and also evaluated the observations of participants in the lab, as well as running a questionnaire with participants. She found fairly poor results (around 40% accurate) in comparison to her own analysis. The results are that 39% identified correctly, 44% functional group, 46% identified as immature – the reliability of the data that adult observers done is better. Results – ID to species level is challenging, especially without help (she didn’t trained the participants) and therefore there is a need of an OPAL community scientist to be an instructor. There was not enough testing of the material at the beginning of the survey and it haven’t been improved since 2009. There is a need to verify records – but should be emphasised further and included in apps. However, despite these limitation, the OPAL survey did yield useful information and they managed to use the data to find abundance of information. Only in 29% of the cases she agreed with participants about the classification of soil granularity. When evaluating the pH of the soil – 63% was within the correct category of acid/alkaline but not correct on the value – the issue might be with the instrument that was provided to participants and yields wrong reading.
In terms of knowledge and experience – the questionnaire was done before, immediately after the survey and then 3 months later. Knowledge increased immediately after but drop-off after – so conclusion is that need to reinforce it after the event. In terms of interest in nature they didn’t find difference – but that because there was high level of interest to start with.
Jodey Peyton (CEH/BRC) ‘Open Farm Sunday Pollinator Survey: Citizen science as a tool for pollinator monitoring?‘. The decline in pollinators in the UK is a cause of concern. Their estimated value is £510 m a year. The Big Bumbelebee discovery is an example for a project that focus on pollinators. However, we’re lacking abundance data about them. The Open Farm Sunday is a project to open farms to the public (run by LEAF) and about 4 years ago they contacted CEH to do some work with visitors collect information on pollinators
They ask participants to observe a 2×2 m of crop and non-crop area. They have an ecologists on site so they do the same as the participants – carry 2 min observations in both habitats. The event included teaching people the process and giving them information. The forms use to be 4 pages but turned out to be too complex so simplified a form with just 2 pages. They also reduce time from 5 min to 2 min. They run surveys in 2012 to 2014 with different number of farms – and looked at different factors during the day. They found that public was over-recording (compare to ecologists), not by much – they also got data from other parts of the plant so not only on the flowers because they wanted to report something. Conclusions – on the broad level public data was similar to ecologists. Lots of interest and enthusiasm and understand what they’re seeing. It is great opportunity to highlight the issue of pollinator. Want to run it every second year because of the effort of the ecologists on the day. They also want to deal with challenge of ‘recording zero. Want to see more collaboration with universities and schools.
Charlotte Hall (EarhtWatch Institute) provided an overview of FreshWater Watch: lessons from a global mass Citizen Science programme. The programme focused on fresh water quality. A global programme that look at water quality in urban areas – each location they partner with local research institute, and Earthwatch bring the citizen scientists with the local researchers. The data that is collected is managed by EarthWatch on a specially designed website to allow sharing knowledge and communictation. The evolving motivation of participants, they looked at Rotman et al 2012 model. Initial involvment stemming from interest or existing knowledge, although in the case of EarthWatch they are getting employees of Shell or HSBC who sponsor them, they also work with teachers in Teach Earth and also expanding to work with local groups such as Thames 21 or Wandle Trust. They have over 20 research partners. With such a mix of researchers, participants and organisations, there are different motivations from different directions. They start with training in person and online Research and learning- EarthWatch is interested in behaviour change, so they see learning as a very important issue and include quizzes to check the knowledge of participants. They pay special attention to communication between EarthWatch and the scientists and between EarthWatch and the citizen scientists. There is a community feature on the website for citizen scientists and also for the scientists. There is also an app with automated feedback that tell them about the outcomes of the research they are doing. They have an element of gamification -points on communication, science and skills that participants gained and they can get to different levels. They try to encourage people to move to the next step so to continue their involvement through learning in webinars, refresher session, research updates, points and prizes and even facility for the participants to analyse the data themselves. Involvement in FreshWater watch is exhibiting participation inequality. They would like to make it shallower but it is very strongly skewed. In Latin America there is better participation, and also differences in participation according to the researcher who lead the activity. This is new citizen science approach for EarthWatch, with different audience, so it’s important to re-evaluate and understand participants. EarthWatch is still learning from that and understanding motivation.
Emma Rothero (Open University) Flight of the Fritillary: a long-running citizen science project linking Snakeshead fritillaries flowers and bumblebees. The work started in 1999, this is a rare plant that is growing only in few places in the UK. The Bees are critical to the flower, and they set a 15% secondary count to evaluate the success of volunteers. They also started winter workshops for discussions. To engage volunteers, they’ve done wide advertising and also used naturalist networks. She described a comparison between three sites where monitoring was carried out this year . In Lugg Meadow the monitoring is done during guided walks and family outreach events. In North Meadow, many people come to see – so they have a gate presence and offered free lunch for volunteers. In Clattinger Farm they haven’t done any specific activity. In 2008 – 20011 only 20 volunteers, now they’ve got 90 volunteers, and about 30-40 who come to winter workshops. Level of volunteering – once 120 , 40 participated twice and 20 three times – there is some enthusiastic people who do it regularly. The volunteers survey show that 88% heard about the monitoring project by word of mouth (despite the advertising and media access), and 87.5% are already recorders – but 88% thought that they had improved their skills. and 65% said that they improve their skills. 54% would like to get involved in other aspects of the project, and 100% enjoyed the activity. In terms of comparison with recounts – they do 4000 1sq m quads using very accurate (1 cm) GPS. They see that there wasn’t difference between recounts in some sites but significantly difference in another site (because of difficulties in frame orientation so implementation of the protocol) – recognising problem in their method. There is also scientific discovery, where they found a case that plants didn’t appear one year but bounced back the next year.
There was no time for much discussion, but a question that was raised and discussed shortly is that most of the projects are ‘top-down’ and led by the scientists, so what is the scope for co-created projects in the area of ecological observations and monitoring?
