N deposition :: Irish Hare

Submitted by Eleanor Campbell on Wed, 10/08/2011 - 16:00

Impact Type: Deposition of pollutant

Key Concerns:

Current work at CEH Banchory on N deposition and mountain hares (Lepus timidus) suggests that N deposition leads to habitat change with a loss of Racomitrium heath. There is evidence to suggest this can have a negative impact on hare numbers, as an increase in grass species favours sheep over hares. Hare numbers then decline. The exact mechanisms are not known at present, however research is ongoing (van de Wal pers. comm.).

Ammonia :: Bats

Submitted by Eleanor Campbell on Tue, 09/08/2011 - 15:54

Impact Type: Direct exposure to pollutant

Key Concerns:

Bats themselves are unlikely to be adversely affected by atmospheric ammonia as peak concentrations of up to 1779 ppm (0.96 mg/dm3) have been recorded at a bat roost (McFarlane et al. 1995).
