I don't know, some are debatable. I tried five or six things for rambarde (like barrier) without getting railing, but maybe that's fair enough. I thought naufrage was closer to sinking (or shipwrecking) than shipwreck (épave), but got there eventually. I tried mountain goat for ibex, but maybe it's ok to be specific. Libellule covers both dragonfly and damselfly in French; I haven't checked to see whether you have it as a type-in already.
I've now changed "naufrage" to "épave", and added "mountain goat" and "damselfly". I remember being hesitant adding "rambarde", since you could easily picture it, but there are so many different names for it. I might consider changing the word if it is too problematic. Thanks again for your help :)
