The data made available on this website is data generated by citizen-scientists. Although the data is screened, it comes with no warranties of any kind concerning completeness, accuracy or reliability.
Note that the data collected here is mostly on a voluntary basis. With regard to the geo-observer data, this implies as well that not all disasters will be reported. Whether or not disasters are reported depends on the locality (is there a geo-observer in the neighbourhood), the local conditions, and the availability of the citizen scientists. By no means should this data set be considered as a complete representation of the disasters in a certain region.
The data collected on snail absence-presence collected through the ATRAP program is likewise collected on a volunteer basis by local citizen scientists. Reported absence of snails does not imply that snails are not prevalent in a certain site, merely that snails were not observed.
