• Dive surveys by trained volunteers • Produces high-quality survey information at spatial and
temporal scales beyond those possible by scientific teams • Global and growing • Dataset feeds into local, state, Commonwealth planning

• Range Extension Database & Mapping
• Record ‘out-of-range’ species
• Started Dec 2009
• Currently being developed Australia-wide
UTAS VC’s Outstanding Community Engagement
Award 2011

Why does Redmap work? • Engaging website
• Immediate display data
• Individual feedback provided
• Recognition of contributions
• Clear acknowledgement of industry & community
• Fishers love talking about what they caught
• Divers love taking photos
For the scientist: validating species ID and verification of sighting
details is simple
Providing feedback to the observer (fisher or diver) is easy - sent an automatic
acknowledgement
Several dozen new and out-of-range species in Tasmania (since 1970)

UNCERTAINTY IN CITIZEN SCIENCE DATA
UNCERTAINTY IN CITIZEN SCIENCE DATA
Navigating the uncertainties in citizen science data for robust analyses Amanda Bates1, Tomas Bird2, Gretta Pecl1, Martin Krkosek3, Rick Stuart-Smith1, Jemina Stuart-Smith1, Graham Edgar1, Neville Barrett1, Stewart Frusher1 and other workshop participants 1 Institute of Marine and Antarctic Studies, University of Tasmania 2 Department of Botany, University of Melbourne 3 Zoology Department, University of Otago
Observers Affect Error and Bias quality e.g., some observers are better at identifying fish than others honesty e.g., fishers report less catch learning e.g., communities are at different learning stages at any one time unequal effort e.g., divers pick the most interesting sites
• Common sources of error and bias • How to characterize our trust in the data • Ways to account for error
– Meta-data (e.g. effort expended, training) – Generalized models (e.g. trust metric) – Field techniques (e.g. validation) – Meta-analytical-style approach (e.g. cross
compatibility of studies)
UNCERTAINTY IN CITIZEN SCIENCE DATA
1. What existing tools are suitable to analyse citizen science data?
2. How can we characterize confidence in the data?
3. What types of tools are currently available to analyse citizen science data?
4. Is there value in generalizing models for analysing citizen science data?
5. What analytical challenges remain?
