The National Park Service is working with the Colorado Department of Public Health and Environment and the Environmental Protection Agency Region 8 (referred to as the Memorandum of Understanding agencies) to reduce atmospheric nitrogen deposition at Rocky Mountain National Park due to its detrimental effects on park ecosystems. The data summarized in this report informs these agencies, stakeholders, and the public about the current status and trends of nitrogen deposition in accordance with the RMNP Nitrogen Deposition Reduction Plan (NDRP). Analyses include assessment of progress along the glidepath and trend analyses for RMNP and other regional sites for the following time periods: long-term/period of record (>32 years), since the 2006 inception of the NDRP, and short-term (the most recent 7 years). Wet N deposition in 2020 at Loch Vale in RMNP was above the glidepath. Long-term trends showed that N deposition levels are stable (no trend), with ammonium concentrations increasing at most of sites and nitrate concentrations decreasing at all sites. Wet N Deposition decreased at Loch Vale in RMNP for the first time since the inception of the NDRP (2006–2020). Other short-term trends indicated that ammonium concentrations were stable, but nitrate concentrations decreased at some sites.
