Population Sizes of Seabirds breeding in Scottish Special Protection Areas

The project has collated existing data on SPA populations breeding around the Scottish coast. The project utilised data from JNCC, SNH, RSPB and other sources. The purpose of the project was to provide a collated source of information for renewable dev


4 SPA accounts

Each SPA account begins with a summary of the SPAs location and size, followed by a table outlining the interest features, the importance of the qualifying numbers, the populations, and the proportion of the population relevant to the designation. In these tables, Annex one species are shaded pink and regularly occurring migratory species are shaded green. Significance is determined by the proportion of the SPA population of the relevant biogeographical population, taken from the SPA review (Stroud et al 2001). No significance is given for species comprising aggregations of over 20,000 seabirds as no population data is available for the citation.

Trends have been assessed by eye, and where apparent, are summarised in tables for each interest feature at each SPA. These tables also summarise the availability of data at each SPA, showing the proportions of count sites counted, and the proportion of years (since the Seabird 2000 census) where data has been collected.

These proportions are then used to assign a 'confidence level' for the trends given, based upon the following matrix.

Sites covered Years 0 - 0.24 0.25 - 0.49 0.5 - 0.74 0.75 - 1
0 - 0.24 very low low low low
0.25 - 0.49 low low mod mod
0.5 - 0.74 low mod mod high
0.75 - 1 low mod high very high

These tables also indicate number of count sites at each SPA, and the year that Seabird 2000 data was collected for each site. Where Seabird 2000 data was collected for different species over different years, this is indicated using the species BTO codes. The BTO codes used in the tables are shown below.

Great cormorant CA Roseate tern RS
European shag SA Sandwich tern SE
Great skua NX Guillemot GU

Each of the relevant species then has a table of raw data, and a table outlining the summary statistics. For species where enough data is available, figures are used to represent population trends (per SPA or per count site).
