This free course, Citizen science and global biodiversity, deals with the importance of biodiversity and explores how anyone can contribute to and be involved in identifying and recording wildlife, as a citizen scientist. It looks at what citizen
science is, and how citizen science facilitates public involvement in scientific research activities as individuals learn and build skills.
Traditional biological keys are introduced and online recording is demonstrated using citizen science techniques and practical activities using the www.iSpotnature.org platform. The course goes on to demonstrate how, once a species is identified, web
resources can be used to research its ecology. The role of citizen science is illustrated through a number of case studies from across the world. Finally, the course concludes by exploring the impact citizen scientists are having on recording biodiversity
around the globe.
