Making marine and coastal citizen science matter

Against the backdrop of a dramatic increase in citizen science activity worldwide, we convened a combined symposium and focus group at the 2014 International Marine Conservation Congress to consider the challenges and opportunities for mobilizing citizen science in the marine and coastal environment. Highlighting the diversity of existing models and approaches to citizen science, participants focused on six different conservation-related outcomes that citizen science projects can potentially support: policy, education, community capacity building, site management, species management; and research. We provide two example case studies of projects and summarize the key themes and recommendations associated with each of those outcomes. The result is a series of toolkits that can help to guide new and existing citizen science projects that aim to support management and conservation of ocean resources, as well as providing insights and recommendations to stimulate further research on and assessment of marine and coastal citizen science programs. Citizen science is an effective approach to conservation and it is time for this underutilized resource to become a more prominent approach for marine and coastal conservation. (C) 2015 Elsevier Ltd.
