This manual brings together information on all phases of seed
handling and presents the results of more than 20 years of studies.
Forest Service field personnel at several experiment stations and
regional offices furnished a backlog of source material for
treatments of individual genera. The manual consists of two main
parts. Part 1 formulates general principles on the various phases
of seed handling from formation of the seed to sowing. Part 2,
which forms the larger part of the manual, provides relatively
detailed but concise information for 444 species and varieties of
trees and shrubs; this includes data on distribution and use,
discussions of seeding habits, methods of seed collection,
extraction and storage, seed germination, and nursery and field
practice.
This is the first book illustrating China's forest carbon projects.
It includes an analysis of the policy and future development trends
of China's forest carbon market and showcases the country's most
representative forest carbon projects. Accordingly, it offers a
valuable resource for all policymakers and researchers interested
in forest carbon, as well as project developers and engineers
involved in forest carbon projects.
This book focuses on fluxes of energy, carbon dioxide and matter in
and above a Central European spruce forest. The transition from a
forest affected by acid rain into a heterogeneous forest occurred
as a result of wind throw, bark beetles and climate change.
Scientific results obtained over the last 20 years at the FLUXNET
site DE-Bay (Waldstein-Weidenbrunnen) are shown together with
methods developed at the site, including the application of
footprint models for data-quality analysis, the coupling between
the trunk space and the atmosphere, the importance of the
Damkoehler number for trace gas studies, and the turbulent
conditions at a forest edge. In addition to the many experimental
studies, the book also applies model studies such as higher-order
closure models, Large-Eddy Simulations, and runoff models for the
catchment and compares them with the experimental data. Moreover,
by highlighting processes in the atmosphere it offers insights into
the functioning of the ecosystem as a whole. It is of interest to
ecologists, micrometeorologists and ecosystem modelers.
The paddy field is a unique agro-ecosystem and provides services
such as food, nutrient recycling and diverse habitats. However,
chemical contamination of paddy soils has degraded the quality of
this important ecosystem. This book provides an overview of our
current understanding of paddy soil pollution, addressing topics
such as the major types of pollutants in contaminated paddy soil
ecosystems; factors affecting the fate of pollutants in paddy soil;
biomonitoring approaches to assess the contaminated paddy soil; the
impact of chemicals on soil microbial diversity; and climate
change. It also covers arsenic and heavy metal pollution of paddy
soils and their impact on rice quality. Further, new emerging
contaminants such as antibiotics and antibiotics resistance genes
(ARGs) in paddy soil and their impact on environmental health are
also discussed. The last chapters focus on the bioremediation
approaches for the management of paddy soils.
This book integrates the different prospective, scientific and
practical experience of researchers as well as beneficiaries and
stakeholders in the field of forest conservation in Southeast
Europe. The book stresses the importance of improving the
adaptability of these ecosystems to the impacts of climate change.
Gathered around a common idea, the book presents the latest results
in forest genetic resources conservation at national and regional
level. The chapters are written by experts from: Bosnia and
Herzegovina, Bulgaria, Croatia, FYR Macedonia, Greece, Montenegro,
Romania, Serbia and Slovenia. The book presents the current state,
legal and institutional framework for conservation and management
of forest genetic resources, case studies and best practices in the
application of different conservation methods and techniques (in
situ and ex situ) as well as climate change aspects in this area.
This book will be of particular interest to scientists and experts
in the field of forestry, environmental protection and rural
development, bachelor, master and doctoral students, as well as for
anyone interested in the conservation issues fuelled by ethical and
economic motives.
With one volume each year, this series keeps scientists and
advanced students informed of the latest developments and results
in all areas of the plant sciences. This latest volume includes
reviews on plant physiology, biochemistry, genetics and genomics,
forests, and ecosystems.
Dothistroma pini changed New Zealand commercial forestry
dramatically. Tree breeding became concentrated on a very few
species and development of selection methods and breeding
strategies changed in response to the new challenges. Tree-Breeding
and Genetics in New Zealand provides a critical historical account
of the work on provenance research and tree breeding, often with
the wisdom of hindsight, and it tracks the development of breeding
strategy, especially for P. radiata, Douglas-fir and the most
important eucalypt species, E. regnans, E. fastigata and E. nitens.
The book is a compendium of abstracts and summaries of all
publications and reports on tree improvement in New Zealand since
the early 1950s, with added critical comment by the author on much
of the work. It is intended for other tree breeders
internationally, for interested NZ foresters and for graduate
students studying genetics and tree breeding.
A burning mix of diesel fuel and gasoline drips from handheld
canisters onto the ground. Slowly a line of fire begins to creep
downhill. The flames are well behaved, almost hesitant. This is a
backing fire, unlikely to attract media attention unless it
escapes, like the disastrous Los Alamos Cerro Grande fire did in
2000. This book explores a century of controversy over prescribed
burning--using fire as a tool--and fire suppression. For more than
100 years, America waged an all-out war against wildland fire.
Decades of fire suppression caused fuels to build up at alarming
levels in our forests, culminating in the increasingly severe,
uncontrollable fires of the late 20th century--the fires in
Yellowstone, the Oakland Hills, and Los Alamos and the fires in
summers of 2000 (the second worst fire season in the nation's
history) and 2001.
Looking at these and earlier fires, Carle uses the voices of
those who were involved, of those who were early advocates, and of
today's proponents to examine the role of controlled burning. Early
in the century, Harold Biswell, a pioneer in prescribed burning,
dared to commit the heresy of questioning the dogma of fire
suppression, despite professional controversy and opprobrium, he
and a few other pioneers led the way. Their roles play an integral
part in the story told here. In Biswell's words, fire is a natural
part of the environment, about as important as rain and sunshine...
. We must work more in harmony with nature, not so much against it.
Can humanity, this book asks, learn to become a fire-adapted
species?
A global synthesis of the impacts of wildfires and controlled
burning on insects, bringing together much hitherto scattered
information to provide a guide to improved conservation management
practice. The great variety of responses by insect species and
assemblages demonstrates the often subtle balance between fire
being a severe threat and a vital management component. Examples
from many parts of the world and from diverse biotopes and
production systems display the increasingly detailed appreciation
of fire impacts on insects in terrestrial and freshwater
environments and the ways in which prescribed burning may be
tailored to reduce harmful ecological impacts and incorporated into
protocols for threatened species and wider insect conservation
benefits.
