check-Risk · Flagging Engine

Select a region and taxa, set your age thresholds, then run the engine. It identifies populations worth conserving — native, introduced, or cryptogenic, everything except aggressive invasives — whose most recent record is old enough to warrant field re-verification, then escalates each based on what has been recorded nearby since: a very recent record of another species raises the level by one, and an invasive neighbour within the buffer raises it to critical. Sites where the species has been re-confirmed recently are not flagged.
