Ecology and Conservation of Forest Birds is a unique review of
current understanding of the relationships between forest birds and
their changing environments. Large ecological changes are being
driven by forest management, climate change, introduced pests and
pathogens, abiotic disturbances, and overbrowsing. Many forest bird
species have suffered population declines, with the situation being
particularly severe for birds dependent on attributes such as dead
wood, old trees and structurally complex forests. With a focus on
the non-tropical parts of the Northern Hemisphere, the text
addresses the fundamental evolutionary and ecological aspects of
forest birds using original data analyses and synthesising reviews.
The characteristics of bird assemblages and their habitats in
different European forest types are explored, together with the
macroecological patterns of bird diversity and conservation issues.
The book provides a valuable reference for ecologists,
ornithologists, conservation professionals, forest industry
employees, and those interested in birds and nature.
Human-wildlife conflict (HWC) is one of the most complex and urgent
issues facing wildlife management and conservation today.
Originally focused on the ecology and economics of wildlife damage,
the study and mitigation of HWC has gradually expanded its scope to
incorporate the human dimensions of the whole spectrum of
human-wildlife relationships, from conflict to coexistence. Having
the conflict-to-coexistence continuum as its leitmotiv, this book
explores a variety of theories and methods currently used to
address human-wildlife interactions, illustrated by case studies
from around the world. It presents some key concepts in the field,
such as values, emotions, social identity and tolerance, and a
variety of insights and solutions to turn conflict into
coexistence, from individual level to national scales, including
conservation marketing, incremental and radical innovation,
strategic planning, and socio-ecological systems. This volume will
be of interest to a wide range of readers, including academics,
researchers, students, practitioners and policy-makers.
Retrogressive thaw slumps (RTS) are caused by thaw of massive
ground ice on slopes and combine subsidence, mass movement, and
water erosion. They can expose several hectares of bare soil that
is susceptible to erosion into nearby water bodies. In the summers
of 2010 and 2011, oblique aerial-photographs of 26 RTS in Noatak
National Preserve (NOAT) and Gates of the Arctic National Park and
Preserve (GAAR) were taken with a hand-held, 35-mm digital camera.
Accurate ground control was obtained at 23 of the slumps by
surveying the location of temporary targets that were captured on
the aerial photographs and then removed. These photographs were
used to create high-resolution three-dimensional topographic models
with photographic overlay. Photographs were taken in both years at
18 of the RTS. The current report: 1) documents changes in the
slumps that had photographs from both years, and 2) describes a new
slump photographed for the first time in 2011.
A land cover map of the National Park Service northwest Alaska
management area was produced using digitally processed Landsat
data. These and other environmental data were incorporated into a
geographic information system to provide baseline information about
the nature and extent of resources present in this northwest
Alaskan environment. This report details the methodology, depicts
vegetation profiles of the surrounding landscape, and describes the
different vegetation types mapped. Portions of nine Landsat
satellite (multispectral scanner and thematic mapper) scenes were
used to produce a land cover map of the Cape Krusenstern National
Monument and Noatak National Preserve and to update an existing
land cover map of Kobuk Valley National Park Valley National Park.
A Bayesian multivariate classifier was applied to the multispectral
data sets, followed by the application of ancillary data
(elevation, slope, aspect, soils, watersheds, and geology) to
enhance the spectral separation of classes into more meaningful
vegetation types. The resulting land cover map contains six major
land cover categories (forest, shrub, herbaceous, sparse/barren,
water, other) and 19 subclasses encompassing 7 million hectares.
General narratives of the distribution of the subclasses throughout
the project area are given along with vegetation profiles showing
common relationships between topographic gradients and vegetation
communities.
In the winter of 1996–97, state and federal authorities shot or
shipped to slaughter more than 1,100 Yellowstone National Park
bison. Since that time, thousands more have been killed or hazed
back into the park, as wildlife managers struggle to accommodate an
animal that does not recognize man-made borders. Tensions over the
hunting and preservation of the bison, an animal sacred to many
Native Americans and an icon of the American West, are at least as
old as the nation's first national park. Established in 1872, in
part “to protect against the wanton destruction of the fish and
game,” Yellowstone has from the first been dedicated to
preserving wildlife along with the park’s other natural wonders.
The Smithsonian Institution, itself founded in 1848, viewed the
park’s resources as critical to its own mission, looking to
Yellowstone for specimens to augment its natural history
collections, and later to stock the National Zoo. How this
relationship developed around the conservation and display of
American wildlife, with these two distinct organizations coming to
mirror one another, is the little-known story Diane Smith tells in
Yellowstone and the Smithsonian. Even before its founding as a
national park, and well before the creation of the National Park
Service in 1916, the Yellowstone region served as a source of
specimens for scientists centered in Washington, D.C. Tracing the
Yellowstone-Washington reciprocity to the earliest
government-sponsored exploration of the region, Smith provides
background and context for many of the practices, such as animal
transfers and captive breeding, pursued a century later by a new
generation of conservation biologists. She shows how Yellowstone,
through its relationship with the Smithsonian, the National Museum,
and ultimately the National Zoo, helped elevate the iconic nature
of representative wildlife of the American West, particularly
bison. Her book helps all of us, not least of all historians and
biologists, to better understand the wildlife management and
conservation policies that followed.
Long-term trends in deer abundance provide one measure of assessing
their potential as a problem for a park. Documenting long-term
patterns in deer numbers allows one to evaluate correlations with
changes in vegetation (e.g., through restoration of the cultural
landscape). With this information resource managers can more
effectively identify and potentially mitigate damage caused to
vegetation communities and endangered plant populations by deer.
Monitoring data also helps managers assess safety risks from
collisions and disease transmission. Long-term monitoring of deer
numbers is critical in evaluating any population control measures a
park may implement.
The newly acquired, nearly complete coverage of ARCN by
high-resolution satellite imagery has allowed the NPS to make a
comprehensive survey of erosion features caused by permafrost thaw
in the Noatak National Preserve (NOAT). The author combined
automated mapping methods with visual recognition of geomorphic
features to make a comprehensive map of ALD and RTS in NOAT. The
purpose of this report is to present the results of mapping in
NOAT. Mapping in three other NPS units (Bering Land Bridge National
Preserve (BELA), Cape Krusenstern National Monument (CAKR), and
Kobuk Valley National Park (KOVA) was reported previously.
The Arctic Network Inventory and Monitoring program (ARCN)
encompasses five park units including Gates of the Arctic National
Park and Preserve (GAAR) and Noatak National Preserve (NOAT). The
landbirds assemblage (passerines, near-passerines, raptors and
galliformes) was chosen by the ARCN for long-term monitoring
because it includes many species that spend the majority of their
lives in terrestrial environments. Specific objectives of the ARCN
landbird monitoring program are to: 1) determine annual longterm
trends in density and frequency of occurrence of 5-10 of the most
commonly detected landbird species along selected river corridors
across ARCN during the breeding season (June); 2) determine annual
long-term trends in landbird species composition and distribution
in selected sites across ARCN during the breeding season (June);
and 3) improve understanding of breeding bird-habitat relationships
and the effects of invasive plants and climatic changes on bird
populations.
