The Cairns Esplanade Bioblitz is a public hands-on citizen science event teaming volunteers with expert scientists and enthusiasts to observe, capture or photograph the local plant and wild life. Hundreds of people are able to contribute to the “citizen science” collection of data which creates a comprehensive picture of the biodiversity of the selected area. The data collected is uploaded at the basecamp on to the Atlas of Living Australia to allow global access to the biodiversity information. Many local Cairns groups are working together to bring an estimated 30 scientist /enthusiast to work with about 300 citizen scientists to survey and record the local biodiversity during the event from 2pm to 8pm on Saturday 17th. We anticipate about 10 school groups for lead-in introductions on Friday 16th.
