Plant species that invade an alien area and outgrow the native vegetation, establishing
and increasing their own territory, often lead to negative economic, environmental,
and social impacts. Even native species can behave like invasive species by their
exponential spread. Similarly, not all non-native species are invasive. Many alien
invasive species, however, do threaten the health and integrity of our terrestrial and
Forest ecosystems cover large parts of the terrestrial land surface and are major
components of the terrestrial carbon (C) cycle. Most important, forest ecosystems
accumulate organic compounds with long C residence times in vegetation, detritus
and, in particular, the soil by the process of C sequestration. Trees, the major components
of forests, absorb large amounts of atmospheric carbon dioxide (CO2) by
photosynthesis, and forests return an almost equal amount to the atmosphere by
auto- and heterotrophic respiration.
The science of forestry is a complex amalgamation
of the biological, physical, managerial, social, and
political sciences. Few, if any, forestry professionals
are able to treat all aspects of forest science with
complete authority. An edited book on forestry is
thus the best method for conveying the science of
forestry in one text.

To clarify the importance and unique features of the approach to the influence of the folk literature on the prose and poetry of Tay people from some literary authors; to partly explain the influence of the folk literature on the prose and poetry of some Tay authors in the modern time in order to put forward the approach and promote the importance of traditional factors in the creation of literary works.
Remote sensing has been defined as the detection, recognition, or evaluation of
objects by means of distant sensing or recording devices. In recent decades, remote
sensing technology has emerged to support data collection and analysis methods of
potential interest and importance in forest management. Historically, digital remote
sensing developed quickly from the technology of aerial photography and photointerpretation
science. In forestry, information extracted visually from aerial photographs
is well-understood, well-used, and integrated with field surveys.
The idea for this book arose during the planning phases of an International Conference
in Edmonton, Canada in July 2004 entitled “The Science of Changing Climates
— Impacts on Agriculture, Forestry and Wetlands.” The conference was organized
jointly by the Canadian Societies of Animal Science, Plant Science and Soil Science
with support from Natural Resources Canada/Canadian Forest Service because they
saw climate change as one of the most serious environmental problems facing the
