This document provides an evaluation of the sensitivity of inventory and monitoring National Parks to Nutrient Enrichment Effects from Atmospheric Nitrogen Deposition for the Rocky Mountain Network (ROMN).

The Appalachian Highlands Network contains three parks that are larger than 100 square miles: Great Smoky Mountains (GRSM), Big South Fork (BISO), and Blue Ridge (BLRI). It also contains one smaller park: Obed (OBRI). National maps of atmospheric N emissions and deposition are provided.

The Pacific Island Network includes islands at diverse locations in the Pacific Ocean (Map PACN-1). It includes the Hawaiian Islands, northern Mariana Islands, Guam, and American Samoa. There are nine parks in the Pacific Island Network. Only one is larger than 100 square miles: Hawaii Volcanoes (HAVO), which is located on the island of Hawaii. The authors detail present data reflecting sensitivity to, and effects from, acidic deposition are sparse for the American Affiliated Islands.

The Pacific Island Network (PACN)includes islands at diverse locations in the Pacific Ocean (Map PACN-1). It includes the Hawaiian Islands, northern Mariana Islands, Guam, and American Samoa. There are nine parks in the Pacific Island Network. Only one is larger than 100 square miles: Hawaii Volcanoes (HAVO), which is located on the island of Hawaii. The authors of this work evaluate and detail their findings regarding nutrient enrichment effect from atmospheric nitrogen depositions in the PACN.

The authors detail the evaluation of the sensitivity of inventory and monitoring Upper Columbia Basin Network to acidification effects from atmospheric sulfur and nitrogen deposition

The authors detail the nutrient enrichment effects from atmospheric nitrogen deposition within the Upper Columbia Basin Network (UCBN).

Report covers natural resource topics of interest and applicability to National Park Service and others in natural resource management.
