Core Count Priority Dates

To aid coordination, counts should be made on the priority dates listed below, ideally during the morning or, at coastal sites, when tidal conditions are suitable. If you are unable to count at this time, please select the nearest suitable alternative date in that month.

Where tidal conditions at coastal sites are unfavourable on these dates, Local Organisers are encouraged to agree alternative dates. Ideally, these should be separated by at least three weeks from counts in the preceding and following months. Counts on different count units within complex sites should be co-ordinated to avoid the possibility of double counting.
