Impact Type: Deposition of pollutant
Key Concerns:
Increases in nitrogen deposition to Scots pine forest may be beneficial to adult capercaillie, as there are potential changes to nutrient value of the pine needles which the adult birds feed on in winter (Spidsx & Korsmo 1993).

Key Concerns:
Blaeberry, Vaccinium myrtillus, is an important component of the understorey vegetation in native pine woodland and plays an important role in the life cycle of some birds (i.e. Capercaillie). A number of studies has shown that raised levels of N deposition lead to increased growth of grasses at the expense of ericaceous shrubs such as Blaeberry (Pitcairn et al. 1998, De Vries et al. 1995).

Impact Type: Deposition of pollutant
Key Concerns:
This rare species is listed under the UK Biodiversity Action Plan (BAP) and occurs on shaded basic, dry habitants in humid locations such as atlantic woodlands. It frequently grows in association with other bryophytes such as Frullania spp and other Lejeunia spp, and may be sensitive to atmospheric nitrogen deposition, which would alter the competitive balance between species.

Key Concerns:
There is evidence that Riccia fluitans actually prefer increased nitrogen inputs. Locally intense nitrogen deposition may therefore favour this species at the expense of other bryophytes (Roelofs 1983).

Key Concerns:
Schistomatomma graphidioides is a lichen growing on parkland trees that appears to be threatened by nitrogen deposition. It is listed under the UK Biodiversity Action Plan. The key concern is fertilisation of parkland combined with intensive grazing or the application of organic manure to neighbouring agricultural land leading to elevated levels of nitrogen deposition from ammonia, as well as nitrogen oxides from roads.

Phosphorus has generally been considered more important than nitrogen in determining the biomass of phytoplankton and the trophic state of the system as a whole (Schindler 1977, Schindler 1978, OECD 1982).
