Despite a century of study by ecologists, recovery following
disturbances (succession) is not fully understood. This book
provides the first global synthesis that compares plant succession
in all major terrestrial biomes and after all major terrestrial
disturbances. It asks critical questions such as: Does succession
follow general patterns across biomes and disturbance types? Do
factors that control succession differ from biome to biome? If
common drivers exist, what are they? Are they abiotic or biotic, or
both? The authors provide insights on broad, generalizable patterns
that go beyond site-specific studies, and present discussions on
factors such as varying temporal dynamics, latitudinal differences,
human-caused vs. natural disturbances, and the role of invasive
alien species. This book is a must-read for researchers and
students in ecology, plant ecology, restoration ecology and
conservation biology. It also provides a valuable framework to aid
land managers attempting to manipulate successional recovery
following increasingly intense and widespread human-made
disturbances.
Restoration of our national forests benefits the environment and
creates jobs in rural communities. Increasing the pace of
restoration of the Nation's forests is critically needed to address
a variety of threats including fire, climate change, the bark
beetle infestation, and others -- to the health of our forest
ecosystems, watersheds, and forest-dependent communities. The
Forest Service within the Department of Agriculture and the Bureau
of Indian Affairs (BIA), Bureau of Land Management (BLM), Fish and
Wildlife Service (FWS), and National Park Service (NPS) within the
Department of the Interior have increasingly promoted
landscape-scale forest restoration as a way to improve forest
health. Through landscape-scale projects, agencies can treat tens
or hundreds of thousands of acres, in contrast to projects commonly
of under 1,000 acres. Such projects must comply with NEPA by
assessing the effects of major federal actions that significantly
affect the environment. This book examines the number of such
projects the agencies have conducted and how they are scoped; the
actions taken by agencies to track the projects' progress;
successes and challenges experienced by agencies; and steps taken
by agencies to help increase NEPA efficiency for such projects.
The Amazon forest is one of the world's most complex, unknown and
threatened ecosystems that holds a considerable part of biodiverse
species in different groups. This ecosystem needs greater
scientific attention so that we can better understand the features
of the fauna, flora and microbiota to conserve species before they
disappear. Thus, this book addresses issues about resources of the
largest rainforest of the world. Microbiota, fauna and flora are
investigated differently, providing information of ecological
interest, pharmaceutical and/or economic importance. Specialists
and scientists that work in Amazonia can access new information
about the species that inhabit this region with unprecedented
advances on ecological and behavioral aspects of apple snails, meat
yield and nutritive potential of crustacean species, tadpole
knowledge, mitefaun in agroecosystems, pharmaceutical potential of
plant species, computational models for flora cultivation, and
reviews of microbiota composition of Amazonia. Scientists will
acquire knowledge about aromatic plants from the Amazon and their
applications, which include uses in perfumes, fragrances,
cosmetics, phytopharmaceuticals, insecticides, fungicides,
bactericides, larvicides and others. Regarding the microbiota of
different Amazonian environments, the book is intended to present
information about applications related to mycorrhizal fungi and
endophytic microorganisms.
Forests possess many components and processes that provide an array
of ecosystem goods and services: timber, energy and water savings,
pollution reduction, livestock forage, habitat for plants and
animals, recreation opportunities, aesthetic landscapes, and
biodiversity that enhance people's quality of life. Forest
resources also support local and regional economies through jobs
and income generated from forestry, agriculture, tourism, and
locational decisions of businesses, retirees, and others. The
capability of a forest to provide these and many other ecosystem
services and to maintain the quality of those ecosystem services
depends on its health. A healthy forest is an essential component
of a healthy ecosystem -- a natural system that is capable of
self-renewal, resilient in its response to disturbances (such as
pest, fire, and other non-human and human-caused disturbances), and
able to sustain the integrity of the natural and cultural benefits
derived from it. This book updates the literature review and
synthesis of economic valuation studies on the impacts of forest
insect pests by Rosenberger and Smith. This book also discusses the
concept of ecosystem services; identifies key elements of each
study; examines areas of future research; and includes appendices
that further explain non-market valuation methods, a narrative of
each study, and tables that summarise each study.
Natural resource policy and management in the United States often
are characterized by limited budgets and multiple, and sometimes
competing, societal objectives. The use and management of forest
lands in the U.S. involve tradeoffs between the current and
potential benefits public and private lands provide to society and
the effects the policy and management actions have on the
resiliency of natural systems. However, translating society's
multiple forestry objectives into policies and management actions
has become more difficult as society's objectives have become more
complex. This book characterizes the concept of ecosystem services
as it could apply to national forests; describes the value of an
ecosystem service approach and provides examples of how management
actions support the provision of these services; compares the
Deschutes National Forest's current accomplishment reporting system
to ecosystem service outcomes that potentially result from
management activities; identifies partners with potential to
collaboratively plan, fund, or implement projects to enhance or
conserve ecosystem services; describes current research efforts to
support management application of the ecosystem service concept;
and identifies research needs.
Fossil records indicate the Neotropical Dry Forests had a more
continuous distribution in the recent geological past, especially
in the late Pleistocene, more precisely at the end of the last
glacial period. Seasonal Deciduous Forests are remnants of a
broader continuous distribution that was present in the past,
ranging from North-Eastern Brazil to Argentina in the Pleistocene
dry period. This currently fragmented structure is the result of
the dry, cold climate that caused the retraction of Wet Forests to
riversides and the spread of seasonal forests. This book discusses
the ecology, species diversity and sustainable management of dry
forests. The topics include a biogeographical overview of the
"lianescent clade" of violaceae in the Neotropical region;
diversity and distribution of hymenoptera aculeate in mid-western
Brazilian dry forests; the Brazilian "caatinga"; changes in the
labile and recalcitrant organic matter fractions due to
transformation of semi-deciduous dry tropical forest to pasture in
the western llanos, Venezuela; ecology and management of the dry
forests and savannas of the western Chaco region, Argentina;
predicting pasture security in rangeland districts of Kenya using 1
km resolution spot vegetation sensor ndvi data.
Scientists tell us that climate change is upon us and the physical
world is changing quickly with serious implications for
biodiversity and human wellbeing. Forests cover vast regions of the
globe and serve as a first line of defence against the worst
effects of climate change, but only if we keep them healthy and
resilient. Forests in Our Changing World tells us how to do that.
Authors Joe Landsberg and Richard Waring present an overview of
forests around the globe, describing basic precepts of forest
ecology and physiology and how forests will change as earth's
climate warms. Drawing on years of research and teaching, they
discuss the values and uses of both natural and plantation-based
forests. In easy-to-understand terms, they describe the ecosystem
services forests provide, such as clean water and wildlife habitat,
present economic concepts important to the management and policy
decisions that affect forests, and introduce the use of
growth-and-yield models and remote-sensing technology that provide
the data behind those decisions. This book is a useful guide for
undergraduates as well as managers, administrators, and policy
makers in environmental organisations and government bodies looking
for a clear overview of basic forest processes and pragmatic
suggestions for protecting the health of forests.
Forest and woodland ecosystems in the world serve important
ecological functions and also contribute to the economic, aesthetic
and spiritual health of humans. In this book, the authors discuss
the structure, species diversity and sustainable management of
woodlands across the globe. Topics include changes in composition
and threats to the sustainable management of woodlands in Portugal;
the role and diversity of soil fauna in woodlands; climate change
and forest fires in the Ave Region of Northwest Portugal; drivers
of deforestation and the potential for carbon trading in the Miombo
woodlands of Zambia; soil microbial diversity in the dry woodlands
of Central-Western Argentina; and developing silvicultural systems
based on disturbance-recovery knowledge of the Southern African
Miombo woodlands.
During the Middle Sican period (C.E. 950-1050) on the North Coast
of Peru, artisans developed a sophisticated tradition of ceramic
and metalworking production amidst dry coastal forests of the
region. Organic fuel resources, specifically wood, clearly played a
vital role in the manufacture of these objects; however, this
component of production has been largely overlooked. Thus, a major
gap in our understanding of the relationship between Sican period
production and the local landscape has developed. The Sican
Archaeological Project (SAP) suggests that the production of metal
and ceramics during this period likely placed the local fuel
resources under considerable stress. Yet, an evaluation of the
archaeological data is essential to assess the degree of
overexploitation, identifying the fuels used, their contexts for
use, and their role in local ecology. This study interprets how
Middle Sican artisans met their fuel-wood requirements for
production in light of easily endangered forest resources. An
examination of the archaeological charcoal from Middle Sican period
kilns, hearths, and metal furnaces permits the reconstruction of
fuel use and the ecological setting of production. This unique site
demonstrates the concurrent production of metal and ceramics, as
well as the presence of domestic activity. Using wood anatomy of
fuels recovered from archaeological features, the author identified
the fuel materials of different use contexts.
The coming global climate changes associated with the increase of
atmospheric greenhouse effect, may disturb the natural carbon cycle
in the biosphere and may lead to large-scale ecological
consequences. The cognition of the mechanisms of environmental
sustainability in changing climate is connected with studying the
biotic regulation of the carbon cycle. Boreal forests play an
important role in the global carbon cycle. This book expounds the
regional-local prognostic conception as a scientific basis of
monitoring forest ecosystems under global climatic changes.
Predictive landscape-ecological scenarios of the nearest future of
temperate forests and their paleogeographical analogues as a single
system of global changes have been considered for the first time by
the example of a large region -- the Volga River basin.
An overview of tropical rainforests for kids. Rainforests describes
tropical rainforests, why they are important, and what is happening
to them. Rainforests is based on the award-winning mongabay.com web
site. "Rainforests" includes discussion of topics including
conservation and protected areas, biodiversity and ecology,
environmental activism, sustainable development, consumption, and
economics.
The Red Hills region of south Georgia and north Florida contains
one of the most biologically diverse ecosystems in North America,
with longleaf pine trees that are up to four hundred years old and
an understory of unparalleled plant life. At first glance, the
longleaf woodlands at plantations like Greenwood, outside
Thomasville, Georgia, seem undisturbed by market economics and
human activity, but Albert G. Way contends that this environment
was socially produced and that its story adds nuance to the broader
narrative of American conservation.
The Red Hills woodlands were thought of primarily as a healthful
refuge for northern industrialists in the early twentieth century.
When notable wildlife biologist Herbert Stoddard arrived in 1924,
he began to recognize the area's ecological value. Stoddard was
with the federal government, but he drew on local knowledge to
craft his land management practices, to the point where a
distinctly southern, agrarian form of ecological conservation
emerged. This set of practices was in many respects progressive,
particularly in its approach to fire management and species
diversity, and much of it remains in effect today.
Using Stoddard as a window into this unique conservation
landscape, "Conserving Southern Longleaf" positions the Red Hills
as a valuable center for research into and understanding of
wildlife biology, fire ecology, and the environmental appreciation
of a region once dubbed simply the "pine barrens."
A study of how encounters between forestry bureaucrats and
indigenous forest managers in Mexico produced official knowledge
about forests and the state. Greater knowledge and transparency are
often promoted as the keys to solving a wide array of governance
problems. In Instituting Nature, Andrew Mathews describes Mexico's
efforts over the past hundred years to manage its forests through
forestry science and biodiversity conservation. He shows that
transparent knowledge was produced not by official declarations or
scientists' expertise but by encounters between the relatively weak
forestry bureaucracy and the indigenous people who manage and own
the pine forests of Mexico. Mathews charts the performances,
collusions, complicities, and evasions that characterize the
forestry bureaucracy. He shows that the authority of forestry
officials is undermined by the tension between local realities and
national policy; officials must juggle sweeping knowledge claims
and mundane concealments, ambitious regulations and routine rule
breaking. Moving from government offices in Mexico City to forests
in the state of Oaxaca, Mathews describes how the science of
forestry and bureaucratic practices came to Oaxaca in the 1930s and
how local environmental and political contexts set the stage for
local resistance. He tells how the indigenous Zapotec people
learned the theory and practice of industrial forestry as employees
and then put these skills to use when they become the owners and
managers of the area's pine forests-eventually incorporating
forestry into their successful claims for autonomy from the state.
Despite the apparently small scale and local contexts of this
balancing act between the power of forestry regulations and the
resistance of indigenous communities, Mathews shows that it has
large implications-for how we understand the modern state,
scientific knowledge, and power and for the global carbon markets
for which Mexican forests might become valuable.
