Crowd sourcing helped develop risk maps for the giant African snail CROWD-SOURCING can help map the distribution of several alien species. Take for instance the highly invasive giant African snail ( Achatinafulica), which was introduced in India in 1847. Researchers geo-tagged information on its distribution across India using data from various Internet and social media sources along with published records. They used the technique of ecological nich modelling to develop risk maps of the giant African snail under various climatic scenarios. Their mapping can help experts take appropriate action to control the species.
Nearly 50 per cent of data on temporal and spatial distribution of the giant African snail, which have been used to develop these maps, has come from crowdsourced information. This highlights the tremendous contribution that citizen scientists can make towards mapping and managing invasive alien species.
