This CCP is the culmination of a planning process that began in
January 1999. Numerous meetings with the public, the state, and
conservation partners were held to identify and evaluate management
alternatives. A draft CCP and Environmental Assessment (CCP/EA) was
distributed in July 2003. This CCP presents the management goals,
objectives, and strategies that we believe will best achieve our
vision for the refuge, contribute to the National Wildlife Refuge
System (Refuge System) Mission, achieve refuge purposes and legal
mandates, and serve the American public.
This document reports on analyses and other efforts to evaluate
various aspects of the monitoring protocols relevant to the big
river parks, and serves as an administrative history and record of
decisions made during the revision process. The primary purpose of
this report is to document evaluation of potential changes to the
monitoring of fish and aquatic invertebrates at BUFF and OZAR.
Changes that have been considered include sampling fewer sites,
sampling less frequently, collecting fewer invertebrate samples per
site, collecting data on fewer habitat variables, and not
collecting data on fish lengths and weights. Based on this review,
recommendations are made for revising the protocols associated with
sampling and analysis of data from the big river systems of BUFF
and OZAR.
The authors conducted a second year of invasive plant surveys at
Lincoln Boyhood National Memorial. This allowed a comparison of
invasive plant species found in 2006 to those found in 2011. their
findings are detailed in this publication.
Throughout the world, freshwater ecosystems are considered to be
among the most vulnerable systems. In the isolated Pacific islands
there are a relatively small number of native freshwater species,
which are mainly endemic to these locations (found nowhere else in
the world). These species are characterized by an amphidromous
lifecycle; reproducing in the stream, with larvae drifting to the
ocean and eventually returning to a stream as juveniles and
spending the remainder of their lifecycle there. Throughout the
region, native flora and fauna face significant threats from
species introductions and habitat destruction. The National Parks
in the Pacific Island Network (PACN) protect some of the last
relatively pristine stream systems. Monitoring based on this
protocol: Pacific Islands Stream Monitoring: Fish, Shrimp, Snails
and Habitat Characterization, will provide park managers with some
of the information necessary to understand status and trends in
biotic integrity within park stream systems.
This is the second progress for a multi-year study of glaciers in
Alaskan national parks. The project will be completed in December
2013. The authors present results from mapping of all glacier
extents in Katmai National Park and Preserve (NP&P) and Lake
Clark NP&P and from measurements of surface elevation changes
on select glaciers in Lake Clark NP&P. They also summarize
field efforts to date associated with the focus glacier component
of the project and present a sample focus glacier vignette.
This is the first progress for a multi-year study of glaciers in
Alaskan national parks. The project will be completed in December
2013. Here we present results from mapping of all glacier extents
in Glacier Bay National Park and Preserve (NP&P) and Denali
NP&P, from measurements of surface elevation changes on select
glaciers in Glacier Bay NP&P, and from focus glacier research
on Brady, Margerie, and Muir Glaciers in Glacier Bay NP&P.
A series of natural resource inventories were conducted throughout
the Boston Harbor Islands, including terrestrial, marine and
estuarine ecosystems. The resource inventories enhance our
appreciation for the habitats and species that occur within the
Boston Harbor Islands landscape. These resource inventories provide
a scientific foundation for natural resource management decisions,
will assist in the design of long-term monitoring programs, and
help identify areas requiring additional inventory.
The upper Yellowstone River was mapped from the northern boundary
of Yellowstone National Park near Gardiner, Montana to the bridge
which crosses the river at Springdale, Montana. The mapped area of
approximately 85 square miles encompasses the majority of the area
that has been flooded by the river in the last 300 years and
therefore includes all wetland and riparian habitat adjacent to the
river as well as surrounding land use. The study area covers all of
the Paradise Valley where the majority of channel modifications
have taken place.
The main purpose of this compilation is to provide a listing of the
chironomid species of the southeastern United States.
This is a detailed guide to the physical remains, history and
topography of the castles of northwest Greece from the early
Byzantine period to the eve of the First World War.
This report summarizes data of the Sonoran Desert Network's first
two seasons of terrestrial vegetation and soils monitoring in
upland areas of Coronado National Memorial, in southern Arizona.
Twelve permanent monitoring sites were sampled. The current report
summarizes effort to date, evaluates the sampling design in the
context of our monitoring objectives, and suggests modifications to
the design.
Acadia National Park (ACAD) lies within a transition zone of the
Maine coastline, containing ecological communities typical of both
southwestern and "downeast" coastal Maine. Eleven of these
communities, or "associations" as defined within the United States
National Vegetation Classification, are rare within the state of
Maine, and one is globally rare. The NPS Northeast Temperate
Network (NETN) is establishing a long-term forest monitoring
program in 10 national park units within the northeastern US. This
program is designed to detect trends in forest condition. At ACAD,
the network has installed 176 permanent forest plots. This sample
size will allow detection of trends in park forests overall, as
well as in some specific ecological communities. However, this
effort will not yield sufficient sample sizes in rare community
associations to assess trends in the condition of these
communities. Rare communities are of particular management and
conservation interest at ACAD, because they are rare and because
they may be particularly sensitive to anthropogenic (human caused)
impacts. This protocol was designed to provide data for the
assessment of status and trend in rare woodland and forest
communities within ACAD, and was adapted from the NETN Long-term
Forest Monitoring Protocol.
First published in 1985, William deBuys’s Enchantment and
Exploitation has become a New Mexico classic. It offers a complete
account of the relationship between society and environment in the
Sangre de Cristo Mountains of northern New Mexico, a region unique
in its rich combination of ecological and cultural diversity. Now,
more than thirty years later, this revised and expanded edition
provides a long-awaited assessment of the quality of the journey
that New Mexican society has traveled in that time—and continues
to travel. In a new final chapter deBuys examines ongoing
transformations in the mountains’ natural systems—including,
most notably, developments related to wildfires—with significant
implications for both the land and the people who depend on it. As
the climate absorbs the effects of an industrial society, deBuys
argues, we can no longer expect the environmental future to be a
reiteration of the environmental past.
