Appendix 6. Species accounts: presentational issues
Each species account is presented in a standard format.
- Section 1 summarises the biological, legal and conservation
status of the species (or sub-species or population) in the
UK.
- Section 2 presents population size and 1% threshold
information. It shows the total number of individuals occurring
within the SPA suite for the species concerned and also expresses
this number as a proportion of relevant national and international
populations. (Relevant international/ biogeographic populations are
defined in Appendix 4, and sources for this information given).
Note that it is possible to have large numbers of a species
occurring within the biogeographic entity of the island of Ireland,
although – through features of dispersal – low numbers in Northern
Ireland (and thus limited occurrence within SPAs there).
- Section 3 briefly summarises the distribution of the species at
global, European and national scales and outlines the taxonomic
status of those birds occurring in the UK with respect to the wider
context of the species. It also notes aspects of the ecology of the
species that are relevant to issues of site-related conservation.
Distributional information, where not cited, is taken from The
Birds of the Western Palearctic (Cramp & Simmons 1977, 1980,
1983, 1985), The Concise Birds of the Western Palearctic (Snow
& Perrins 1998), the Handbook of the Birds of the World (del
Hoyo et al. 1992, 1994, 1996) as well as from the EBBC European
Bird Atlas (Hagemeijer & Blair 1997).
- Section 4 outlines the presence of different populations of the
same species that may be present in the UK and provides information
on corresponding population sizes and trends in these, generally
over the last 30-40 years.
- Section 5 summarises the number of SPAs selected for each
species. It also highlights relevant wider conservation measures
being undertaken for the species, where those measures are
specifically targeted to that species' conservation requirements.
In particular, it notes the implementation of national and
international action/biodiversity plans by the UK.
- Section 6 presents the process of site selection used to
develop the species' SPA suite. In particular, it presents
justification for any sites selected under Stage 1 of the
guidelines but not subsequently selected under Stage 2. It also
presents the reasoning for the selection of 'additional' SPAs under
Stage 1.4.
- The final section of the account presents a map showing the
location of sites within the species' SPA suite and a table listing
the sites selected, the total number of birds per site, the
proportions of national and international populations present on
each site and the guideline by which each site was selected. Note
that for non-breeding waterbirds, the total presented against each
site is (generally) the five year peak mean count, whilst the suite
total presented at the bottom of the table derives from a
'snapshot' assessment of the suite in January or another relevant
month. This is in order to ensure there is no double-counting of
birds through the use of inappropriate statistics (see Appendix 5, section A5.4
for further information).
- Each species account includes a map showing the location of
selected sites within the SPA suite for the species concerned.
Sites for species selected under Guidelines 1.1, 1.2 and 1.4 are
indicated by a diamond symbol (
). Sites where the species forms an important
component of an assemblage identified under Guideline 1.3 are shown
by a square (
). Note
that the symbols used are not proportionate to the size of the
site. Maps in the Site Section (Appendix 7,
sections A7.3–A7.23 - See the UK Index of regional maps) give the
locations of each site, and show boundaries of classified sites or
the indicative size of proposed sites.
Note:
Note that in the species accounts and elsewhere, the term
'international population' is used synonymously to refer to the
relevant biogeographical population of the species concerned. It
does not refer to the total world population for which the terms
'global population' or 'global numbers' are used where they are
relevant.
