Key Scottish Environment Statistics 2009

Footnotes

1) Due to changes in definitions that have been applied retrospectively, the estimates from 1990 are not in all cases directly comparable to the later surveys.

4) A small number of councils did not participate in every survey. In these cases, the most recent available data is used to provide an estimate for the appropriate year. Sites must be at least 0.1 hectares in size to be included.
5) Figures may not sum due to rounding.
6) Land also qualifies as derelict if it has an unremedied previous use which could constrain future development.
7) Scottish Government (2009). Scottish Vacant and Derelict Land Survey 2008.
8) Figures are as at 31st March each year.
9) Area (ha) figures are rounded to the nearest thousand hectares and % to the nearest whole number. Area (ha) figures exclude the area in England of cross-border sites. Area (ha) figures for SACs include both land and marine areas.
10) Some SSSIs overlap, and where this occurs the area of overlapping land will be counted more than once. In 2009 this accounted for around 2,500 hectares, so the net area of SSSI sites at 31 ^st March 2009 is approx 1,036,000 hectares.
11) The area of an SSSI is based on the documented area stated on each citation at the time the site was notified or reviewed. Where an SSSI has been reviewed under the Nature Conservation (Scotland) Act 2004 and the citation area figure has been changed to a more accurate GIS measurement, SSSI area totals will reflect the revised area from the date of SSSI review, but retrospective SSSI area totals have not been adjusted. As a result of this it is possible for the overall SSSI area figure to change from one year to the next without there being any actual change in SSSI site boundaries on the ground.
12) Some SACs overlap, and where this occurs the area of overlapping land will be counted more than once. In 2009 this accounted for around 5,500 hectares, so the net area of SAC sites at 31 ^st March 2009 is approx 957,000 hectares. Figures include both designated SACs and candidate SACs submitted to the EC.
13) Figures may not sum to total due to rounding.
14) Figures from Scottish Government June Agricultural Census.
15) Only includes woodland on agricultural holdings. For total woodland area see page 46.
16) Excludes Orkney, Shetland and the Western Isles.
17) Total quantity of nutrient used (kg) divided by the total extent of crop area (ha) (including any areas without application of the nutrient).
18) Department for Environment, Food and Rural Affairs, Scottish Government (2009). The British Survey of Fertiliser Practice 2008.
19) The non-Forestry Commission component of the 2009 figure is based on data obtained from the 1995-1999 National Inventory of Woodlands and Trees.
20) Woodland is defined as land under stands of trees with a canopy cover of at least 20%, or having the potential to achieve this, including integral open space, wooded agricultural land, and felled areas that are awaiting restocking.
