Rocky Mountain National Park Initiative, nitrogen deposition reduction contingency plan
The importance of atmospheric nitrogen (N) deposition relative to the natural processes and natural character of Rocky Mountain National Park (RMNP) has become better understood over time, as scientific research and monitoring that began in the early 1980's have documented various changes to ecosystems in the park. These changes include forest and soil biogeochemical changes, enhanced microbial activity in soils, increased N in lakes and streams, changes in surface water chemistry, altered tree chemistry, and shifts in species of aquatic plants. The park's unique resources will continue to be harmed if N deposition remains constant or increases. In 2004 a multiagency meeting including the Colorado Department of Public Health and Environment (CDPHE), the National Park Service (NPS), and the U.S. Environmental Protection Agency (EPA) was held to address the effects and trends of N deposition in RMNP, and related air quality issues including elevated ozone concentrations and visibility impairment., memorandum of understanding agencies: National Park Service, Environmental Protection Agency, Colorado Department of Public Health & Envirgonment ; endorsed by the Colorado Air Quality Control Commission in a non-binding agreement as of June 17, 2010., "June 21, 2010.", Online resource; title from PDF cover (viewed June 2017)
