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.
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.
This report covers the mid-1970'2 to the mid-1980's, a period in which Federal, State, and local government programs and policies began to affect wetland use and conversion. For this reason, there has been intense interest by the scientific and governmental communities in these updated wetlands statistics. Although the data contained in this report generally predates more recent wetlands legislation, they provide information that can help to assess the effectiveness of public policies and programs that have been intended to reduce the loss of the Nation's remaining wetlands.
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 main purpose of this report is to document how wetlands in the Meadowlands area changed from the 1950s to the 1990s. The emphasis is on quantitative changes (i.e., changes in extent; acreage) and not on qualitative changes in wetlands. The report also presents other information that provides a valuable perspective on these and prior changes.
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 abstract describes the Final Management Plan and Environmental Impact Statement for the Florida Keys National Marine Sanctuary. Congress, recognizing the degradation of this unique ecosystem due to direct physical impacts and indirect impact, passed the Florida Keys National Marine Sanctuary and Protection Act of 1990 designating the Florida Keys National Marine Sanctuary.
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.
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.
Few of us will ever get to Antarctica. The bitter cold and three months a year without sunlight makes the sixth continent virtually uninhabitable for humans. Yet marine biologist James B. McClintock has spent three decades studying the frozen land in order to understand better the world that lies beneath it. In this luminous and closely observed account, one of the world's leading experts on Antarctica introduces the reader to this fascinating world - the extraordinary wildlife that persists despite the harsh conditions and the way each of the pieces fit into the puzzle of the intricate environment: from single-celled organisms to baleen whales, with leopard seals, penguins, 50-foot algae, sea spiders, coral, and multicolored sea stars, in between. Now, as temperatures rise, the fragile ecosystem is under attack. Adelie penguins that have successfully nested on Antarctic islands for several hundred years have been nearly wiped out. King crabs that used to populate the deep seafloor are moving into shallower waters, disturbing the set order of life there. Lost Antarctica is an appeal to understand and appreciate the wondrous place at the bottom of the world that we are on the brink of losing.
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.
The U.S. Geological Survey and the USDA Forest Service partnered to co-host a symposium on "Planning for Biodiversity: Bringing Research and Management Together," held February 29-March 2, 2000 at the Kellogg West Conference Center, California State Polytechnic University in Pomona, California. The goal of the 3-day conference was to identify the current status of our knowledge and gaps in our understanding of regional biodiversity and ecosystem processes, present and future threats to species and habitats, and effective monitoring strategies for southwestern and central coastal California resources. Through a program of 52 invited presentations, 18 contributed posters, and 10 focused discussion groups, the conference created an environment for formal and informal communication among the 300 attendees about the results of scientific studies and their application to resource conservation and management, as well as the information needs of managers responsible for determining and implementing management on the ground. Of the 45 technical papers presented at the conference, 14 are included in this volume. Authors were asked to synthesize the current state of knowledge regarding their topic and identify areas needing future research. Each paper was assigned to an editor for review and received one to three additional peer reviews. Expanded abstracts of nine posters also were reviewed by the editors and included. The topics addressed in the papers and poster abstracts reflect the breadth of the conference presentations and the issues facing the science and management communities, ranging from the threats of fire, air pollution, grazing, exotic species invasion, and habitat loss on native habitats and sensitive species of birds, mammals, reptiles and amphibians, to the role of mycorrhizal fungi as indicators of biological change.
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.
This report presents the conceptual ecological models describing the structure and function of terrestrial ecosystems for park units in the Eastern Rivers and Mountains Network (ERMN, see Table 1). These models have been developed to support the National Park Service's (NPS) Inventory and Monitoring Program (I&M Program) in this region, and in particular, to complement the identification of "vital signs" that will be used in long-term monitoring of park resources.
This document details the objectives of current monitoring program including 1) determine the status and trends of invertebrate species diversity, abundance, and community metrics, and 2) relate the 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.
This report summarizes the results of the U.S. Fish and Wildlife Service's findings, with emphasis on the wetlands associated with the islands in the designated Boston Harbor Islands NRA.

The purpose of this report is to explain how the NWIPlus data could be and was used for predicting wetland functions at the landscape-level for coastal Georgia and the rationale for assigning certain biotic and/or abiotic characteristics to eleven wetland functions: 1) surface water detention, 2) coastal storm surge detention, 3) streamflow maintenance, 4) nutrient transformation, 5) carbon sequestration, 6) sediment and other particulate retention, 7) bank and shoreline stabilization, 8) provision of fish and aquatic invertebrate habitat, 9) provision of waterfowl and waterbird habitat, 10) provision of other wildlife habitat, and 11) provision of habitat for unique, uncommon or highly diverse wetland plant communities.
The Comprehensive Conservation Plan (CCP) for Muleshoe National Wildlife Refuge (NWR) and Grulla NWR will serve as a management tool to be used by the refuge staff and its partners in the preservation and restoration of the ecosystem's natural resources. In that regard, the plan will guide management decisions over the next 15 years and set forth strategies for achieving refuge goals and objectives within that time frame. The results of the planning process are represented within this document. Management actions identified within this document reflect a need to achieve a number of refuge goals that are supported by measurable objectives and specific implementation strategies.
This report summarizes results of the Sonoran Desert Network's first season of terrestrial vegetation and soils monitoring in upland areas of Gila Cliff Dwellings National Monument (NM), in southwestern New Mexico. Ten permanent field-monitoring sites were established and sampled in 2009. Our objectives were to determine the status of and detect trends, over five-year intervals, in vegetation cover, vegetation frequency, soil cover, and surface soil stability.
