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.

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.
This book tells the story of the hopeful science and trusting art
of forestry. It is a story about the hopes of foresters and other
scientists to understand the forests more deeply, and about their
unspoken trust that their knowledge could ensure an enduring sylvan
future. Much has been written on the origins and development of
modern forestry in various countries, and on the people and
institutions involved, but there is little in the forest history
literature that explains what the science actually is. Forest
knowledge has an ancient history documented since classical times
and applied within the intricate social and legal systems of
medieval Europe. This volume is concerned with the modern form of
forest science, founded in Europe early in the nineteenth century,
when regimes for managing the forests, that could be traced to the
ancient world and had flourished in the Middle Ages, were
disrupted. New ways had to be found. Foresters have tried to know
their forests scientifically for over three centuries and have
hoped to apply their knowledge to good effect, even though they
could not live to see the futures they envisioned. How far did
their scientific understanding enable a sylvan future? What, over
the three centuries discussed in this book, were their successes
and failures? And now what might the future hold for forest science
and its application? This is no tale of triumph: the outlook for
the world's forests is too bleak for that. While many forests are
flourishing, the climate is changing, tropical forests are
disappearing, others are degrading, species are being lost,
governments dither, international conferences fail. This is
another, longer story - one of inquiry, of science and persistent
endeavour to find a better future for the forests.

Agroforestry seeks to balance protection of forest resources, the
exploitation of the ecosystem services that trees can contribute to
agriculture and the role of agroforestry in diversifying the range
of agricultural products and markets. This volume reviews the
latest research on the role and implementation of main types of
agroforestry, understanding and assessing the ecosystem services
that agroforestry can deliver and techniques for optimising
agroforestry practice. The book's main focus is on temperate
agroforestry, but also reviews particular issues facing
agroforestry in the tropics. The collection will be a standard
reference for forestry and agricultural scientists in universities,
government and other research centres in agroforestry
* 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."
