Evaluation of the Sensitivity of Inventory and Monitoring National Parks to Nutrient Enrichment Effects from Atmospheric Nitrogen Deposition: Southern Colorado Plateau

The National Park Service (NPS) is a United States agency established in 1916, that works with all
national parks and memorials across the nation. This report series evaluates the relative sensitivity
of National Park Service parks and inventory & monitoring networks to potential nutrient enrichment
effects caused by atmospheric nitrogen deposition. Such effects can be caused by the addition of
oxidized nitrogen (NOx) and/or reduced nitrogen (NHx) to natural ecosystems. Nutrient nitrogen
enrichment can occur in both terrestrial and aquatic ecosystems. Nitrogen from air pollution sources
can alter plant and algal communities and affect biodiversity. This is one of their reports.
