Info

Overall, vascular plant diversity decreased by 9.8% between 1998 and 2007. Seven of the 10 broad habitats showed significant decreases (acid grassland; broadleaved, mixed and yew woodland; coniferous woodland; bog; improved grassland; fen; marsh and swamp; and neutral grassland). Habitat condition in protected areas The condition of Scotland’s 1,451 protected areas, including marine environments, provide additional insights into habitat condition (S11 – Notified Habitats in Favourable Condition Indicator): - 55% of habitat features were in favourable condition; 17% were in unfavourable recovering; and 27% were unfavourable. - 99% of marine and 83% of coastal features were favourable/unfavourable recovering. - 78% of freshwater and 76% of wetland features were favourable/unfavourable recovering. - 66% of upland, 65% of woodland, 81% of lowland heathland and 65% of lowland grassland features were favourable/unfavourable recovering. - 96% of geological features were favourable/unfavourable recovering. 10.3 Trends in the status of priority habitats and species Habitats and species that are strongly in decline or especially vulnerable have been identified for targeted action and are referred to as biodiversity ‘priority’ habitats and species. Priority habitats Based on a review in 2007, the number of biodiversity priority habitats that occur in Scotland was increased to 60 in 2008. The scope and / or definition of 11 of the previous habitats were also modified. Trend assessment therefore depends on comparing like-with-like, based on a restricted number of comparisons, or the latest status assessment. Both are provided here. Thirty-nine assessments in 2005 were repeated in 2008 (Table 10.2) for the following habitats: eutrophic standing waters; coastal and floodplain grazing marsh; lowland fens; lowland raised bog; mesotrophic lakes; arable field margins; hedgerows; lowland calcareous grassland; lowland dry acid grassland; lowland heathland; lowland meadows; purple moor grass and rush pastures; upland hay meadows; blanket bog; limestone pavements; upland calcareous grassland; upland heathland; lowland mixed deciduous woodland; native pine woodlands; upland mixed ashwoods; upland oakwood; wet woodland; wood-pasture & parkland; coastal saltmarsh; machair; horse mussel beds; maerl beds; saline lagoons; Serpulid reefs. Assessments are based on systematic survey where possible, but sometimes rely on expert judgement. 70
The proportion of habitats which were declining remained unchanged at 34% in 2005 and in 2008. Those stable or increasing rose, from 36% in 2005 to 45% in 2008.

A more complete account, although not comparable between years, is based on 41 assessments in 2005 and in 2008 (Table 10.3). Those stable or increasing in 2008 (41%) exceeded those declining (31%). 71
