The National Park Service's Arctic Network (ARCN) seeks to understand the natural resources and to detect changes and trends in those resources in five NPS units, including Gates of the Arctic National Park and Preserve, Kobuk Valley National Park, Noatak National Preserve, Cape Krusenstern National Monument, and Bering Land Bridge National Preserve (Figure 1).

This document describes the concept, organization, and application of a hierarchical ecosystem classification that integrates saline and tidal freshwater reaches of estuaries in order to characterize the ecosystems of large flood plain rivers that are strongly influenced by riverine and estuarine hydrology. We illustrate the classification by applying it to the Columbia River estuary (Oregon-Washington, USA), a system that extends about 233 river kilometers (rkm) inland from the Pacific Ocean. More than three-quarters of this length is tidal freshwater.

Beaches serve as a natural barrier between the ocean and inland communities, ecosystems, and natural resources. However, these dynamic environments move and change in response to winds, waves, and currents. During extreme storms, such as powerful hurricanes, changes to beaches can be large, and the results are sometimes catastrophic. Lives may be lost, communities destroyed, and millions of dollars spent on rebuilding.

This report summarizes the results of the 2002-2003 inventory of birds, mammals, and herpetofauna, summarizes historic information, and contains brief accounts of each species present or expected to occur in the Whitman Mission National Historic Site (WHMI). Information on species that are possible but unlikely to occur in the mission is also included.

The purpose of this study was to collect baseline water quality information on the Sound and the freshwater brooks flowing into the Sound. A depauperate water quality data base and concern over the potential for increased residential development throughout the Somes Sound watershed were incentives for initiating this study.

This annual report details the status of key indicators of water quality obtained from monitoring that occurred in Whitman Mission National Historic Site (WHMI) in 2009, 2010, and 2011. WHMI natural resource staff monitored Mill Creek in 2009, Doan Creek in 2010, and Mill Creek again in 2011.

During surveys in 2009, we documented seven invasive exotic plant taxa in the Big Spring Pines Natural Area, Chubb Hollow, Long Bay Field and Long Bay at Ozark National Scenic Riverways. All species were known to occur on the park. The most widespread and abundant of the exotic plant species observed included Johnsongrass, ground ivy and Nepalase browntop. Each of these species covered seven or more acres in the park. In general, several invasive exotic plants are a major problem in the study area at Ozark National Scenic Riverways, but successful control is possible for a large group of species. The acreage estimates presented in the report may be used to plan management activities leading to control of exotic plants and the accomplishment of GPRA goal IA1b.

Aquatic invertebrates are an important biomonitoring tool for understanding and detecting changes in ecosystem integrity over time. Therefore, the monitoring objectives of this protocol as described by DeBacker et al. (2005) are: 1) Determine the status and trends of invertebrate species diversity, abundance, and community metrics. 2) Relate invertebrate community to overall water quality through quantification of metrics related to species richness, abundance, diversity, and region-specific multi-metric indices as indicators of water quality and habitat condition.

The Apostle Islands National Lakeshore (APIS) vegetation mapping project is an initiative of the National Park Service (NPS) Vegetation Inventory Program (VIP), with cooperative support from the U.S. Geological Survey (USGS) Vegetation Characterization Program (VCP), to classify and map plant communities of APIS. The goals of the project are to adequately describe and map plant communities of APIS and immediate surroundings and provide the NPS Natural Resource Inventory and Monitoring (I&M) Program, resource managers, and biological researchers with useful baseline vegetation information.

The National Park Service initiated a restoration project at Saugus Iron Works National Historic Site to restore the historic turning basin and wetland area adjacent to the Saugus River in 2007. To fulfill regulatory requirements and enhance understanding of freshwater wetland restoration practices, an intensive, pre- and post-restoration monitoring program was implemented. This report summarizes monitoring data collected prior to the restoration and the first year (2008) after restoration. Data summaries included in this report describe the status of biotic (e.g., vegetation, nekton, avian, benthic invertebrate, and vegetation communities) and abiotic parameters (e.g., tidal hydrology, river geomorphology, sediment, and water quality). This is first of several monitoring reports associated with the restoration of the turning basin and wetlands at Saugus Iron Works National Historic Site.

This report to the Congress details the status and trends of our Nation's wetlands. It covers the period from 1986 to 1997, and provides the most recent and comprehensive estimates of the current status of wetland area throughout the conterminous United States and the losses or gains to various wetland types that have occurred during this time.

This report summarizes results of the Sonoran Desert Network's first season of terrestrial vegetation and soils monitoring in upland areas of Fort Bowie National Historic Site (NHS), in southeastern Arizona. Ten permanent field-monitoring sites were established and sampled in 2008. Our objectives were to determine the status of and detect trends, over five-year intervals, in vegetation cover, frequency, soil cover, and surface soil stability.

The Pictured Rocks National Lakeshore (PIRO) vegetation mapping project is an initiative of the National Park Service (NPS) Vegetation Inventory Program (VIP), with cooperative support from the U.S. Geological Survey (USGS) Vegetation Characterization Program (VCP) to classify and map plant communities of PIRO. The goals of the project are to adequately describe and map plant communities of PIRO and immediate surroundings and to provide the NPS Natural Resource Inventory and Monitoring (I&M) Program, resource managers, and biological researchers with useful baseline vegetation information.

The purpose of this publication is to report the findings of the Service's wetlands inventory of New Jersey and to summarize existing information on New Jersey's wetlands. The chapters will include discussions of wetland concept and classification; National Wetlands Inventory techniques and results; wetland formation and hydrology; hydric soils, wetland vegetation and plant communities; wetland values; wetland trends; and wetland protection. The appendix contains a list of plants found in NJ's wetlands. A figure showing the general distribution of NJ's wetlands and deepwater habitats is provided.

The report is organized into the following sections: Study Area, Methods, General Scope and Limitations of the Study, Appropriate Use of this Report, Rationale for Preliminary Functional Assessments, Results, Conclusions, Acknowledgments, and References. Two appendices provide keys to hydrogeomorphic wetland classification and the functional assessment findings for subbasins. Thematic maps are contained in a separate folder on the CD version of this report.

This report is one in a series of community profiles whose objective is to synthesize extant literature for specific wetland habitats into definitive, yet handy ecological references. This report details not only the biology of floodplains but also the geomorphological and hydrological components and processes that are operating on various scales.

During 2006 through 2009 the National Park Service Great Lakes Inventory and Monitoring Network and its partners assessed levels of targeted environmental contaminants in bald eagle (Haliaeetus leucocephalus) nestlings at sites in and adjacent to the Apostle Islands National Lakeshore, Mississippi National River and Recreation Area, and St. Croix National Scenic Riverway.

The Natural Resource Publication series addresses natural resource topics that are of interest and applicability to a broad readership in the National Park Service and to others in the management of natural resources, including the scientific community, the public, and the NPS conservation and environmental constituencies. Manuscripts are peer-reviewed to ensure that the information is scientifically credible, technically accurate, appropriately written for the intended audience, and is designed and published in a professional manner.

Whitebark pine is declining across much of its range in North America because of the combined effects of mountain pine beetle epidemics, fire exclusion policies, and widespread exotic blister rust infections. This management guide summarizes the extensive data collected at whitebark pine treatment sites for three periods: (1) pre-treatment, (2) 1 year post-treatment, and (3) 5 years post-treatment (one site has a 10 year post-treatment measurement). Study results are organized here so that managers can identify possible effects of a treatment at their own site by matching it to the most similar treatment unit in this study, based on vegetation conditions, fire regime, and geographical area. This guide is based on the Restoring Whitebark Pine Ecosystems study, which was initiated in 1993 to investigate the effects of various restoration treatments on tree mortality, regeneration, and vascular plant response on five sites in the northern Rocky Mountains. The objective was to enhance whitebark pine regeneration and cone production using treatments that emulate the native fire regime. Since data summaries are for individual treatment units, there are no analyses of differences across treatment units or across sites.
