For thousands of years, forest biomass or wood has been among the
main energy sources of humans around the world. Since the
industrial revolution, fossil fuels have replaced wood and become
the dominant source of energy. The use of fossil fuels has the
disadvantage of increasing atmospheric concentrations of greenhouse
gases (GHGs), especially carbon dioxide (CO2), with the consequent
warming of global climate and changes in precipitation. In this
context, the substitution of fossil fuels with renewable energy
sources like forest biomass is among the ways to mitigate climate
change. This book summarizes recent experiences on how to manage
forest land to produce woody biomass for energy use and what are
the potentials to mitigate climate change by substituting fossil
fuels in energy production. In this context, the book addresses how
management can affect the supply of energy biomass using
short-rotation forestry and the conventional forestry applying long
rotations. Furthermore, the book outlines the close interaction
between the ecological systems and industrial systems, which
controls the carbon cycle between the atmosphere and biosphere. In
this context, sustainable forest management is a key to understand
and control indirect carbon emissions due to the utilization of
forest biomass (e.g. from management, harvesting and logistics, and
ecosystem processes), which are often omitted in assessing the
carbon neutrality of energy systems based on forest biomass. The
focus in this book is on forests and forestry in the boreal and
temperate zones, particularly in Northern Europe, where the woody
biomass is widely used in the energy industry for producing energy.
This open access book will provide an introduction to forest
entomology, the principles and techniques of forest insect pest
management, the different forest insect guilds/feeding groups, and
relevant forest insect pest management case studies. In addition to
covering 30% of the earth, forest ecosystems provide numerous
timber and non-timber products that affect our daily lives and
recreational opportunities, habitat for diverse animal communities,
watershed protection, play critical roles in the water cycle, and
mitigate soil erosion and global warming. In addition to being the
most abundant organisms in forest ecosystems, insects perform
numerous functions in forests, many of which are beneficial and
critical to forest health. Conversely, some insects damage and/or
kill trees and reduce the capacity of forests to provide desired
ecosystem services. The target audience of this book is upper-level
undergraduate and graduate students and professionals interested in
forest health and entomology.
The National Forestry Handbook (NFH) contains methodology,
procedures, and related reference materials that assist NRCS
personnel to implement the policies contained in the National
Forestry Manual (NFM) relative to forestry and agroforestry
technologies. All references to the Soil Conservation Service or
SCS by Public Laws, Memoranda or other documents stated herein have
been changed to the Natural Resources Conservation Service or NRCS,
respectively. All policies and responsibilities relating to
forestry previously assigned to the Soil Conservation Service are
carried forward in full to the Natural Resources Conservation
Service unless otherwise noted or amended in this handbook.

* Stresses workplace safety and risk assessment * Covers basic tree
felling, intermediate tree felling and advanced tree felling
including hazardous trees * Theory of felling, directional felling,
preparation, escape route and cutting the scarf * Builds on the
information provided by the "Chainsaw Operator s Manual"The "Tree
Faller s Manual" is an essential handbook for forest operators and
others who need to fell trees manually using a hand-held chainsaw.
This manual builds on the information provided by the "Chainsaw
Operator s Manual." Tree felling is a high risk activity. Many
fatalities and serious injuries have occurred as a result of being
struck by falling trees, dislodged tree limbs or other dangers in
the area. Most of these accidents are caused by using unsafe
felling techniques and not following safe work procedures. This
manual will guide the faller to safer work techniques. The manual
is based on the national competency standards for the forest and
forest products industry where tree felling is covered using three
categories: basic, intermediate and advanced. Basic tree felling
applies to trees that are relatively small, with a single stem and
no defects. Intermediate tree felling covers trees with single or
multiple stems, limited defects, and lean and weight distribution
that can be adapted to felling direction. Advanced tree felling
applies to larger and more complex trees and includes trees deemed
to be more hazardous. Workplace safety, risk assessment and site
preparation are included along with the theory, techniques and
tools for each of the tree-felling categories."
After the 1998 flood of the Yangtze River, one of the world s most
important rivers, environmental experts realized that, to control
flooding, much more attention must be paid to vegetation cover on
bare lands, thin forest land, and shrub-covered land in mountain
areas. In 1999, an environmental monitoring project of the forests
in 11 provinces of the Yangtze River basin was undertaken. This
book reports on soil loss prediction and the successful practices
of soil loss control in eastern China in recent years.
