This edited book, composed of chapters written by scholars of the
geomatics-based, environmental and biological sciences, examines
selected topics from the intersecting fields of geomatics
(including remote sensing, geographical information science (GIS),
global positioning systems (GPS), mapping and field survey methods)
and conservation biology (including ecology and conservation
policy), with case studies from West Africa, Canada, India and
Malaysia. The focus is on some of the more important issues that
dominate current intersections between developments in geomatics
technology and those of conservation biology. Chapter One examines
the history and themes of geomatics and applications to
conservation biology research. Chapter Two presents a case study of
geomatics-based research on the vital issue of vulture ecology,
extinction and conservation in Central India. Chapter Three
examines the relationship between people and elephants in the Dalma
Wildlife Sanctuary and its surroundings in India, and it creates
habitat suitability models from geomatics techniques to assess and
predict elephant presence and potential human-elephant conflicts.
Chapter Four examines the history and status of remote sensing as
an aspect of geomatics, focusing mainly on satellite imagery.
Chapter Five looks at development in GIS and takes an example of
multidirectional landcover change from the West African savanna.
Chapter Six looks at developments in GPS technology, especially
concerning applications to the micro-habitats of bird presence and
applications to mammal behavior. Chapter Seven looks at the
subfield of animal geography, which looks at the subjective
behavior of individual animals and the technology used to measure
these detailed phenomena. Chapter Eight takes a case study of bird
migration and habitat utilization in the swamps of coastal
Malaysia. Chapter Nine looks at the utility of dated aerial
photographs and supporting field methods in the evaluation of
historical landcover change, covering periods before the
development of modern imaging techniques and using an example from
the West African savanna. This book makes an important contribution
to the intersections of geomatics and conservation biology.
This practical manual of freshwater ecology and conservation
provides a state-of-the-art review of the approaches and techniques
used to measure, monitor, and conserve freshwater ecosystems. It
offers a single, comprehensive, and accessible synthesis of the
vast amount of literature for freshwater ecology and conservation
that is currently dispersed in manuals, toolkits, journals,
handbooks, 'grey' literature, and websites. Successful conservation
outcomes are ultimately built on a sound ecological framework in
which every species must be assessed and understood at the
individual, community, catchment and landscape level of
interaction. For example, freshwater ecologists need to understand
hydrochemical storages and fluxes, the physical systems influencing
freshwaters at the catchment and landscape scale, and the spatial
and temporal processes that maintain species assemblages and their
dynamics. A thorough understanding of all these varied processes,
and the techniques for studying them, is essential for the
effective conservation and management of freshwater ecosystems.
Ponds and pools are a common feature of our landscape – there are
at least ten times as many ponds as lakes in the UK – and they
are also important wildlife habitats. This book provides a
comprehensive and detailed account of these freshwater habitats.
The first chapter discusses what ponds, pools and puddles are, how
they differ from rivers and lakes, their origin – natural or
man-made, the different types of ponds and their abundance and
distribution in Britain. A second chapter looks at ponds as ancient
natural habitats that have existed for millennia on the earth’s
surface. Ancient pond communities, as preserved in inter- and
post-glacial sediments, are compared with modern pond communities.
This chapter also examines the physical and chemical environment of
ponds, covering aspects such as size, shape and depth, hydrology,
oxygen and temperature. Ponds, pools and puddles are important
wildlife habitats; they are as rich in species as rivers, and
support rare and uncommon taxa including about half of Britain’s
Red Data Book wetland plant and animal species. The authors give a
comprehensive survey of the variety of plant and animal life for
which ponds, pools and puddles are a habitat, with a chapter each
on plants, invertebrates, amphibians, and fish, birds and mammals.
The book discusses the importance of ponds to each of these groups
and the ways in which the organisms exploit ponds, describing their
habitats and major variations in life cycles. The pond ecosystem
and colonisation and succession are discussed in two further
chapters, before the final chapter, which is devoted to the subject
of conservation and how best to protect and manage ponds and pond
wildlife in Britain today. In spite of their evident importance,
ponds have been largely ignored by freshwater biologists during
this century. Ponds, Pools and Puddles makes an invaluable
contribution to raising awareness of these popular, yet frequently
underrated freshwater habitats, giving them the attention they
rightly deserve.
Bees play a vital and irreplaceable role in pollinating our
flowers, fruits and vegetables. The more bees in your garden the
healthier, more productive and more pleasant a place it will be.
Yet bees are declining rapidly and many people, even if they do not
wish to keep bees themselves, are asking what can be done on an
individual basis to help the bee. This book is a response to that
request. It will demonstrate in one accessible volume how each of
us can play our part in providing a bee-friendly environment, no
matter how much gardening space and/or time we may have. It
includes: * How bees forage, what bees you can expect to find in
your garden and what plants are best for them. * Why honey bees are
so important; what they need to thrive and how they detect and
access those requirements; and what varieties of plants are best
suited to provide those needs. * How the gardener can offer and
maintain a bee-friendly garden, followed by a season-by-season
account of what beefriendly plants are in flower and when, and what
jobs the gardener can be doing during these times to help bees
thrive. * A gazetteer of selected bee-friendly plants, arranged by
type of plant in seasonal sub-sections. * Illustrative, practical
planting plans, including a culinary herb garden, a potager, a wild
flower garden, and a 3 seasons traditional border.
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.
