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.
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.
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.
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 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 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.
This is a synthesis of scientific information and literature
concerning the maritime forests of the southern Atlantic Coast of
the United States. Information was gathered from many sources,
including published scientific literature, dissertations and
theses, government agency reports and newsletters, and unpublished
reports.
The main purpose of this compilation is to provide a listing of the
chironomid species of the southeastern United States.
NatureServe contracted with the New Hampshire Natural Heritage
Bureau (NH Heritage) to conduct a survey and produce a map of the
vegetation of Saint-Gaudens National Historic Site. NatureServe
ecologists planned the sampling, oversaw the field effort, and
integrated plot and accuracy assessment data and field information
into the U.S. National Vegetation Classification (USNVC) to produce
a standardized product for the National Park Service. The purpose
of this project was to produce a standardized map and
classification of the vegetation communities and land cover of the
Saint-Gaudens National Historic Site and to provide thorough
baseline data on the park's vegetation.
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.
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 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.
