N.B. Each SITE has one or more SPECIES records (spreadsheets) associated with
it, these being linked to that site by the unique 3-figure Site Code.
(M = mandatory category)

(NB: Grid references west of Greenwhich and south of the equator are given as
negative numbers)
1M Unique Site Code (3-figure)
2 Site Identifier (eg. Pyrenees, Australian Capital Territory
etc.)
3M Longitude (in declimalized degrees)
4M Latitude (in declimalized degrees)
5 Altitude (in metres)
6M Declines at Site? (1=yes, 0=no)
7 Declines Occurred After: (eg. 198712 = declines occurred after
December 1987)
8 Declines Occurred Before: (eg. 198905 = declines occurred prior
to June 1989)
