Second paragraph: As a nature reserve... It isn't stated anywhere prior to this that the island is a nature reserve. This should either be mentioned before, or it should be stated as a fact, not mentioned in passing.
The rest of this para is a blow-by-blow Covid account. It should be rephrased in such a way that the entire closure is discussed as one, rather than this "sequence of events" style.
What's the significance of whelk snails? Are they native, naturalised, invasive? And can you link to the appropriate species (or at least genus) instead of the whelk article?
Unfortunately, the article does not say what species they were looking for, although this can probably be found in some supplementary literature. jp×g08:13, 27 March 2021 (UTC)[reply]
Okay, I'll respond to that when you get around to it. In the meantime I will take a crack at the stuff you've mentioned so far. jp×g03:47, 27 March 2021 (UTC)[reply]
GA review (see here for what the criteria are, and here for what they are not)
Nice work. The addition of the maps really enhances my understanding. I think it would help readers a lot if you explained what the maps show in their captions. Guettarda (talk) 13:20, 27 March 2021 (UTC)[reply]
