Book Description
Forest biomass is the second-largest renewable energy resource in Canada, representing a major pool in the global carbon budget, but better estimates of forest biomass are needed. In the 1980s, numerous empirical biomass equations were developed for estimating forest biomass. However, many of these were reported inconsistently by different authors in terms of their form and parameter values, even for the same species, which has complicated their application. This study was undertaken to review existing methods of biomass measurement and estimation, and to identify and evaluate the existing biomass equations that might be most suitable for estimating the biomass of major species at a large spatial scale in westcentral Canada. Seventeen commonly used biomass equations and two biomass extrapolation methods were compared at the individual tree and stand scales for major species in west-central Canada. The biomass equations usually provided more consistent estimates for medium-sized trees than for small or large trees. Equations developed for the Prairie provinces and/or for national data sets were more appropriate for estimating the individual tree biomass of six boreal forest species in west-central Canada. There were no significant differences between the mean tree method and the normal distribution approach for extrapolating from individual tree biomass to stand biomass. For shrub understory biomass, there were no significant differences among the species-specific equations. For estimating belowground biomass, equations based on the aboveground biomass are recommended; therefore, accurate estimation of aboveground biomass is a prerequisite for accurately determining belowground biomass.

Book Description
This book demonstrates in detail all phases of the 9th National Forest Inventory of Finland (1996–2003): the planning of the sampling design, measurements, estimation methods and results. The inventory knowledge accumulated during almost one hundred years is consolidated in the book. The purpose of the numerous examples of results is to demonstrate the diversity of the estimates and content of a national forest inventory. The most recent results include the assessment of the indicators describing the biodiversity of forests. The Finnish NFI has been and is a model for many countries worldwide. The methods and results of the book are set in the international context and are applicable globally. The book provides a valuable information source for countries, institutions and researchers planning own inventories as well as modifying the existing ones, or seeking the applicable definitions and estimation methods to use in their own inventories.

Book Description
The problems related to the process of industrialisation such as biodiversity depletion, climate change and a worsening of health and living conditions, especially but not only in developing countries, intensify. Therefore, there is an increasing need to search for integrated solutions to make development more sustainable. The United Nations has acknowledged the problem and approved the “2030 Agenda for Sustainable Development”. On 1st January 2016, the 17 Sustainable Development Goals (SDGs) of the Agenda officially came into force. These goals cover the three dimensions of sustainable development: economic growth, social inclusion and environmental protection. The Encyclopedia of the UN Sustainable Development Goals comprehensively addresses the SDGs in an integrated way. It encompasses 17 volumes, each one devoted to one of the 17 SDGs. This volume addresses SDG 15, namely "Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss" and contains the description of a range of terms, which allow a better understanding and foster knowledge. Concretely, the defined targets are: Ensure the conservation, restoration and sustainable use of terrestrial and inland freshwater ecosystems and their services, in particular forests, wetlands, mountains and drylands, in line with obligations under international agreements Promote the implementation of sustainable management of all types of forests, halt deforestation, restore degraded forests and substantially increase afforestation and reforestation globally Combat desertification, restore degraded land and soil, including land affected by desertification, drought and floods, and strive to achieve a land degradation-neutral world Ensure the conservation of mountain ecosystems, including their biodiversity, in order to enhance their capacity to provide benefits that are essential for sustainable development Take urgent and significant action to reduce the degradation of natural habitats, halt the loss of biodiversity and protect and prevent the extinction of threatened species Promote fair and equitable sharing of the benefits arising from the utilization of genetic resources and promote appropriate access to such resources, as internationally agreed Take urgent action to end poaching and trafficking of protected species of flora and fauna and address both demand and supply of illegal wildlife products Introduce measures to prevent the introduction and significantly Reduce the impact of invasive alien species on land and water ecosystems and control or eradicate the priority species Integrate ecosystem and biodiversity values into national and local planning, development processes, poverty reduction strategies and accounts Mobilize and significantly increase financial resources from all sources to conserve and sustainably use biodiversity and ecosystems Mobilize significant resources from all sources and at all levels to finance sustainable forest management and provide adequate incentives to developing countries to advance such management, including for conservation and reforestation Enhance global support for efforts to combat poaching and trafficking of protected species, including by increasing the capacity of local communities to pursue sustainable livelihood opportunities Editorial Board Alexandra Aragão, Desalegn Yayeh Ayal, Ayansina Ayanlade, Anabela Marisa Azul, Adriana Consorte-McCrea, Muhammad Farooq, Ana Catarina Luz, María P.

Book Description
Boreal forests form Earth's largest terrestrial biome. They are rich in ecosystem and landscape diversity, though characterized by relatively few plant species, as compared to other forested regions. The long term viability and sustainability of boreal forests is influenced by many factors. They are subject to interruptions at intervals by large-scale natural disturbances, and increasingly by human activities. Boreal ecosystem development is typically a slow process; hence rapid changes in the global environment may invoke complex responses. Many industrial nations border, or lie within, boreal regions, deriving much of their economic wealth and culture from the forests. The response of boreal forests to changes in the global environment - whether caused by direct human activity or by indirect changes such as the anticipated changes in climate - are therefore of considerable international interest, both for their policy implications and their scientific challenges. This book which contains almost 50 peer-reviewed papers from a world-wide group of experts assembled under the auspices of IBFRA, the International Boreal Forest Research Association, covers topics which will stimulate further research and the development of constructive policies for improved management and conservation of global boreal forest resources.

Book Description
Above ground biomass has been listed by the Intergovernmental Panel on Climate Change as one of the five most prominent, visible, and dynamic terrestrial carbon pools. The increased awareness of the impacts of climate change has seen a burgeoning need to consistently assess carbon stocks to combat carbon sequestration. An accurate estimation of carbon stocks and an understanding of the carbon sources and sinks can aid the improvement and accuracy of carbon flux models, an important pre-requisite of climate change impact projections. Based on 15 research topics, this book demonstrates the role of remote sensing in quantifying above ground biomass (forest, grass, woodlands) across varying spatial and temporal scales. The innovative application areas of the book include algorithm development and implementation, accuracy assessment, scaling issues (local–regional–global biomass mapping), and the integration of microwaves (i.e. LiDAR), along with optical sensors, forest biomass mapping, rangeland productivity and abundance (grass biomass, density, cover), bush encroachment biomass, and seasonal and long-term biomass monitoring.
