Nature photographer's social media posts are helping improve biodiversity conservation mapping in South Asia, and the method could go global. Researcher Dr Shawan Chowdhury, from the University of Queensland's School of the Environment, led the international team that scoured images on Facebook nature photography groups in Bangladesh to add to the existing Global Biodiversity Information Facility database. The study was published in Bioscience, One Earth, and Conservation Biology.
Researchers discovered almost 1000 vulnerable species in Bangladesh
Dr Chowdhury said, "We found 44,000 photos of almost 1,000 animal species, including many birds and insects, 288 of which are considered threatened in Bangladesh. This has vastly improved habitat mapping across the country where only 4.6 per cent of land is designated as protected."
"We identified many more high-priority areas for conservation, spanning 4,000 square kilometres for birds and 10,000 square kilometres for butterflies. We'd been missing out on the distribution data of hundreds of endangered species in Bangladesh, which is a great result," Dr Chowdhury continued. "This could change how scientists gather biodiversity information in the future, especially in regions where there is a lack of reliable and up-to-date structured monitoring to inform conservation efforts," added Dr Chowdhury.
In Australia, social media posts are used to track pest species
Social media posts are used to track pest species in Australia. Dr Chowdhury said, "A South Asian butterfly, called the tawny coster, entered Australia in 2012. We've searched for additional locality records from Facebook to analyse the movement, ecology and colonisation status of this species and shown that it expanded at about 135 kilometres per year in Australia between 2012 and 2020."
Co-author Professor Richard Fuller from UQ said, "While Facebook has been helpful, there are some big opportunities for social media companies. There is currently no automated way to collect this information, and it was arduous for us to do it manually." Additionally, he said, "We hope our research can inspire the development of technology such as an app that transfers biodiversity data posted on Facebook directly to the global biodiversity databases. This way, conservation scientists can easily access and use that data."
