Statistics that fail independent corroboration are excluded.

Plant has clocked 2.7 billion plant observations in 2025, yet only a fraction ever gets tagged with the kind of details that make a dataset truly searchable. That mismatch between volume and usable data shapes everything from regional trends to how fast new insights can emerge.
