Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'Red List' literally as 'Красный список', which loses the official connotation. Use the standard term 'Красная книга' (though technically 'Красная книга' often refers to national lists; for the global IUCN list, 'Красный список МСОП' is precise).
- Do not confuse with 'Чёрный список' (blacklist).
Common Mistakes
- Saying 'the IUCN's Red List' (the 's' is often dropped in the official title).
- Using 'Red List' as a verb (e.g., 'The species was red-listed' is informal; 'listed on the Red List' is standard).
- Capitalising incorrectly ('red list' instead of 'Red List').
