Stray whitespace in taxonomy fields

Source: IUCN Red List 2026-1 (CSV export) · 1,099 rows

The table below lists taxonomy field values with a whitespace problem: leading or trailing spaces, repeated spaces, or non-breaking and tab characters. Every row includes a suggested normalised value. The same scan also checks for infrarank markers written into the wrong field and for the scientificName column disagreeing between the assessments and taxonomy files of the CSV export; the summary below shows what each check found, including checks that found nothing. Otherwise-invisible characters in the current value are shown as visible markers, so the difference can be seen.

Why it matters

Stray whitespace breaks exact-match comparisons, sort order, and search, and can appear as visible gaps on the website. Each case is small, but they add up across the release.

Suggestion

Apply the suggested normalised value. These are low-risk, concrete tidy-ups.

By kind of problem

Each kind is counted once per field row; because one field can have several, the kinds add up to more than the distinct total.

Problem	Rows
leading whitespace	89
trailing whitespace	875
double spaces	241
non-breaking or control whitespace	73
infrarank marker prefix	0
scientificName differs between the assessments and taxonomy files	0
Total (distinct rows)	1,099

The CSV can be applied as-is: every row gives the taxon id, the field, the current value, and the replacement value. Each row has a stable id, kept across releases, for citing a row or tracking it in the next release.
