Press release 2012/11 - Issued by the NERC Centre for Ecology & Hydrology, UK


A new practical guide on how to develop, implement and evaluate citizen science projects to monitor the UK’s environment is published today. The guide is based on conclusions from a comprehensive report reviewing more than 200 citizen science projects from the UK and around the world.

Scientists from the NERC Centre for Ecology & Hydrology and the Natural History Museum in London were commissioned by the UK Environmental Observation Framework (UK-EOF) to undertake a review of citizen science.  The aim of the project “Understanding Citizen Science and Environmental Monitoring” was to learn lessons from past citizen science projects.  The report and guide published today are particularly timely because there is growing interest in using citizen science, an increasingly valuable approach to scientific discovery, for environmental monitoring purposes.

Citizen science can broadly be defined as the involvement of volunteers in science.  The UK-EOF project reviewed 234 projects ranging in scale from small one-off local surveys, such as a bioblitz in a local park, to large scale long-term programmes, such as the UK Butterfly Monitoring Scheme. The project team studied the motivations of volunteers, held structured interviews with users of citizen science and environmental monitoring data, and looked at how such projects help meet policy needs.

The practical guide accompanying today’s full project report shares the good practices found during the review process, making suggestions on how to plan, carry out, and evaluate citizen science projects to provide benefits for both participants and potential data users.

Project leader Dr Helen Roy from the Biological Records Centre at the NERC Centre for Ecology & Hydrology said, “It has been fantastic to have the opportunity to review such a wide range of citizen science projects. Our work shows the high value of citizen science to research, policy and practice, as well as its importance in connecting thousands of people to their environment across the UK, and the wider world.”

Professor Doug Wilson, Head of Scientific and Evidence Services in the Evidence Directorate at the Environment Agency and chair of the UK-EOF Management Group said, “Citizen science has a vital role in scientific research and education, and the potential to help meet some of the challenging demands of environmental monitoring at the national scale. This gives citizen science a clear relevance to government policy across the UK. The easily accessible Guide, along with the supporting Report, will provide a fabulous resource for anyone interested in working with volunteers in citizen science.”

Lead author of the practical guide Dr John Tweddle, from the Angela Marmont Centre for UK Biodiversity at the Natural History Museum, said, “Volunteer participation in the observation of nature and wider environmental monitoring has a long and illustrious history, especially in Britain. It’s a fun and rewarding pastime that plays a huge role in improving our scientific understanding. Our Guide aims to support anyone with an interest in developing their own citizen science project - and new communication technologies, like mobile phone apps and environmental sensors, mean that it has never been easier to get involved.”

The project concluded that:

  • Environmental-based citizen science has a wide scope. For centuries citizen scientists have monitored a broad range of plants, animals and fungi (80% of the projects reviewed involved biodiversity) as well as contributing data on weather and the wider environment using many varied approaches (from citizen-led projects with local community groups to, more commonly, scientist-led mass participation initiatives that are open to all sectors of society).
  • The use of recent technological developments is revolutionising citizen science - for example the use of on-line recording, such as iRecord, and smartphone apps, such as PlantTracker.
  • Data quality from citizen science can be excellent, even though this is not yet recognised by all researchers and policymakers – citizen scientists working alongside professional scientists or using appropriate quality assurance and validation processes provide data of a very high standard and additionally have the capacity to provide data across large geographic areas and over long timescales.
  • Citizen science is a very cost-effective way of collecting environmental data. During one year alone, volunteer observers for biodiversity surveillance in the UK were estimated to contribute time in-kind worth more than £20 million.  However, despite relying on volunteers, citizen science is not free. The analysis carried out showed that projects providing data relevant to policy development typically have annual running costs of between £70k and £150k, spent, for example, on website or smartphone app development, publicity material, data management and event costs, on top of the in-kind contribution of volunteers.
  • There is potential to make considerably more use of citizen science than is currently the case. A good example is the surveillance and monitoring of invasive non-native species building on the work of existing projects such as the GB Non-Native Species Information Portal (GB-NNSIP) which already encourages people to submit records of species of concern to an online alert system.

Both the full report and the practical guide are free to download (from the UK-EOF, CEH and NHM websites) and can be distributed for non-commercial purposes.

The UK Environmental Observation Framework - Changing the way the UK perceives, values and uses environmental observations - UK-EOF aims to facilitate the ongoing environmental evidence required to understand the changing natural environment, thus guiding current and future environmental management, policy science and innovation priorities for economic benefit and quality of life. UK-EOF is a partnership of: Countryside Council for Wales, Department for Environment Food and Rural Affairs, Department of Energy and Climate Change, Economic and Social Research Council, Environment Agency, Forestry Commission, Joint Nature Conservation Committee, Met Office, Natural England, Natural Environment Research Council, Northern Ireland Environment Agency, Scottish Environment Protection Agency, Scottish Natural Heritage, The Scottish Government, UK Space Agency, Welsh Government. UK-EOF was launched in 2008 to address issues of fragmentation, data access and a lack of strategic direction in environmental monitoring. Together with its partners UK-EOF aspires to identify and address the issues surrounding environmental observations made for and by the UK. UK-EOF seeks to provide a cost effective mechanism to work in partnership across government, the devolved administrations, agencies and the voluntary sector to make the best use of expertise and resources in support of national and international goals.

The Natural History Museum is an award-winning tourist attraction and also a world-leading science research centre. Through its collections and scientific expertise, the Museum works to help understand and maintain the richness and diversity of our planet, with groundbreaking partnerships in more than 70 countries.

Scotland's Environment Web (SEWeb) brings together information on Scotland's environment in one place. Environmental data and reports from known and trusted sources can be accessed and looked at in combination.
