Where does the Borneo Grainy Frog sighting chance come from?

GBIF citizen-science records

It is estimated from how often the Borneo Grainy Frog is recorded against all the amphibians logged in Kubah National Park (6 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
