natura 2000 standard data form - Suffolk Coastal District Council

Table4a: Five-year autumn peak counts, and month in which this was recorded, of each
species.
Where a count is enclosed by parentheses this indicates that it was considered incomplete
i.e. those parts of the site not visited typically holds at least 25% of the species in question.
Incomplete counts are excluded from calculation where, if included, they would depress the mean.
When all counts are considered to be incomplete the maximum replaces the mean.

Data provided by the British Trust for Ornithology on behalf of The Wetland Bird Survey.
These tabulations are based exclusively on data collected as part of the monthly Core Counts.
For some species (e.g. wintering geese) data collected by other surveys may be more appropriate for the purpose of site assessment.
Missing or unexpectedly low counts for gulls and terns should be treated with caution - counting these groups is optional and determination of count effort not always possible.
The Wetland Bird Survey is a partnership between the British Trust for Ornithology, The Wildfowl
and Wetlands Trust, the Royal Society for the Protection of Birds and the Joint Nature Conservation Committee,
the latter on behalf of Natural England, Scottish Natural Heritage, the Countryside Council for Wales and
the Environment and Heritage Service in Northern Ireland.
