Choosing and Using Citizen Science a guide to when and how to use citizen science to monitor biodiversity and the environment Acknowledgements We would like to thank the Scottish Environment Protection Agency (SEPA) for funding this guide and Claire Campbell at SEPA for her enthusiasm and guidance. We thank the Centre for Ecology & Hydrology for providing support during the guide’s production and to Heather Lowther and Amanda Hill for their superb contribution to its design. Finally thank you to the volunteers and citizen science enthusiasts who have inspired this guide. Citation Pocock, M.J.O., Chapman, D.S., Sheppard, L.J. & Roy, H.E. (2014).

Citizen science is very diverse; there are many different ways for volunteers to get involved with real science. This diversity can be overwhelming for someone seeking to organize a citizen science activity and citizen science will not always be the most appropriate or optimal approach for undertaking scientific research or monitoring. Here we aim to provide guidance to support people considering using a citizen science approach, especially (but not necessarily Photo: Michael Pocock, CEH restricted to) monitoring biodiversity and the environment in the UK. It will help you decide whether citizen science is likely to be useful, and it will help you decide which broad approach to citizen science is most suitable for your question or activity. This guide does not cover the practical detail of developing a citizen science project. That information is provided in the ‘Guide to Citizen Science’ (Tweddle et al., 2012). iii Contents About this guide Introduction to citizen science What is citizen science? 2 The aim of this guide 2 1 Why is citizen science so popular? 3 Citizen science and its role in long-term monitoring 4 Advantages and disadvantages of a citizen science approach Advantages of a citizen science approach 5 2 Disadvantages of a citizen science approach 5 A decision framework for choosing and using citizen science Precursor to the decision framework 7 Before you choose citizen science 8 The clarity of the aim or question 8 The importance of engagement 8 The resources available 9 3 The scale of sampling 9 The complexity of the protocol 10 The motivations of participants 10 Examples of using citizen science 11 Types of data 13 The decision framework How to use the decision framework 14 Using the decision framework with a clearly defined question 14 4 Using the decision framework interactively 14 The decision framework for citizen science 15 Notes on the decision framework 18 Final thoughts on choosing and using citizen science Resources: the organisers' time 20 Resources: infrastructure and data protection 20 Validation, quality assurance and verification 21 5 Communication 21 Participant safety 22 Legislative implications 22 Conclusion 22 References and resources Introduction to 1 citizen science What is citizen science?

Therefore, for someone with Citizen science is an In this guide we provide a question to answer, or a increasingly popular approach a decision framework to monitoring need to be met, it to undertaking monitoring help guide people who can be daunting to consider and scientific research.

For projects involving environmental monitoring in which there is a clear end-use for the data, the contributory model of citizen science is usually most relevant.
