Bioindicator and biomonitoring methods for assessing the effects of atmospheric nitrogen on statutory nature conservation sites 2004
Atmospheric nitrogen deposition represents a threat to naturally nutrient-poor plant communities, leading to a potential loss of conservation value for many statutory nature conservation sites. Until now, the regulatory assessment of these impacts has been focused on the critical loads approach, where estimated atmospheric deposition loads are compared with ‘critical loads’ to estimate the occurrence and extent of ‘critical load exceedance’.
Critical loads represent the deposition below which environmental effects do not occur, according to present knowledge. Hence, where exceedance occurs on nature conservation sites, ecological changes are expected.
