N deposition :: Dotterel
Impact Type: Deposition of pollutant
Key Concerns:
Current work suggests that N deposition leads to habitat change, with a loss of Racomitrium heath (Milne & Hartley 2001). This impacts on the birds through loss of nesting sites and reduction in insect prey (sawfly larvae) for the chicks (van de Wal pers comm.).
Additional Comments:
The move from moss dominated heath to grasses also increases trampling by sheep, so increasing the risk of destruction of nests and eggs.
