A number of habitats have been identified as both sensitive
and vulnerable to acid deposition, including heathland, bog and
grassland habitats. This report will focus on:
• acid grassland (lowland dry acid grassland, upland acid
• bogs (raised bogs, lowland blanket bog, blanket bog and valley
• heathland (lowland heathland, subalpine dry dwarf-shrub heath,
These habitats are amongst the most sensitive and vulnerable to
nitrogen (N) deposition. They are also widespread habitats that
occur in many SSSIs.
Across the investigated habitats, few of the existing CSM site
condition indicator species were suitable for determining the
impact of N deposition on a site. More evidence is needed on the
impacts of N deposition on individual species.
