Allometric Equations for Biomass Estimation of Woody Species and Organic Soil Carbon Stocks of Agroforestry Systems in West African: State of Current Knowledge
International Journal of Research in Agriculture and Forestry Volume 2, Issue 10, October 2015, PP 17-33 ISSN 2394-5907 (Print) & ISSN 2394-5915 (Online) Allometric Equations for Biomass Estimation of Woody Species and Organic Soil Carbon Stocks of Agroforestry Systems in West African: State Of Current Knowledge Massaoudou Moussa1, Larwanou Mahamane2, Mahamane Saadou3 1Department of Natural Resources Management (DGRN), National Institute of Agricultural Research of Niger (INRAN), BP 240 Maradi, Niger 2African Forest Forum (AFF) C/o World Agroforestry Center (ICRAF), P.O. Box 30677–00100, Nairobi, Kenya 3Department of Biology, Faculty of Science, University Abdou Moumouni of Niamey, Niamey, Niger ABSTRACT Since the Kyoto Protocol, agroforestry is considered as a mitigation and adaptation tool to climate change. Agro forestry systems are nowadays the subject of many investigations all over the world. This is because of their potential for carbon sequestration and storage. The parklands are some ancient cultural systems with a wide distribution in West Africa. The contribution of these systems to climate change mitigation has to do with the organic carbon storage in soils and sequestration of atmospheric carbon. This study aims at presenting an overview of the current knowledge on soils organic carbon and allometric equations for estimating aboveground biomass in agro forestry land use systems in West Africa. Significant amounts of carbon, ranging from 0.29 to 32 MgC.ha-1.year-1, were sequestered according to specific argroforestry systems. Yet, allometric equations for many species are lacking as carbon stock in several soil types needs to be estimated. Indeed, further studies need to be undertaken therein. -

Urban Forest Assessments Resource Guide
Trees in cities, a main component of a city’s urban forest, contribute significantly to human health and environmental quality. Urban forest ecosystem assessments are a key tool to help quantify the benefits that trees and urban forests provide, advancing our understanding of these valuable resources. Over the years, a variety of assessment tools have been developed to help us better understand the benefits that urban forests provide and to quantify them into measurable metrics. The results they provide are extremely useful in helping to improve urban forest policies on all levels, inform planning and management, track environmental changes over time and determine how trees affect the environment, which consequently enhances human health. American Forests, with grant support from the U.S. Forest Service’s Urban and Community Forestry Program, developed this resource guide to provide a framework for practitioners interested in doing urban forest ecosystem assessments. This guide is divided into three main sections designed to walk you through the process of selecting the best urban forest assessment tool for your needs and project. In this guide, you will find: Urban Forest Management, which explains urban forest management and the tools used for effective management How to Choose an Urban Forests Ecosystem Assessment Tool, which details the series of questions you need to answer before selecting a tool Urban Forest Ecosystem Assessment Tools, which offers descriptions and usage tips for the most common and popular assessment tools available Urban Forest Management Many of the best urban forest programs in the country have created and regularly use an Urban Forest Management Plan (UFMP) to define the scope and methodology for accomplishing urban forestry goals. -

A ever before-recreation, watershed protection, wildlife, timber, "'--;':r: .";'C: wilderness. Foresters are often able to enhance production of these bene- fits. This book features forestry techniques that are helping to achieve .,;~~.~...t& the American dream for the forest. , ~- ,.- The story is for landolVners, which means it is for everyone. Millions . .~: of Americans own individual tracts of woodland, many have shares in companies that manage forests, and all OWII the public lands managed by government agencies. The forestry profession exists to help all these landowners obtain the benefits they want from forests; but forests have limits. Like all living things, trees are restricted in what they can do and where they can exist. A tree that needs well-drained soil cannot thrive in a marsh. If seeds re- quire bare soil for germination, no amount of urging will get a seedling established on a pile of leaves. The fOllOwing pages describe th.: ways in which stands of trees can be grown under commonly Occllrring forest conditions ill the United States. Originating, growing, and tending stands of trees is called silvicllllllr~ \ I, 'R"7'" -, l'l;l.f\ .. (silva is the Latin word for forest). Without exaggeration, silviculture is the heartbeat of forestry. It is essential when humans wish to manage the forests-to accelerate the production or wildlife, timber, forage, or to in- / crease recreation and watershed values. Of course, some benerits- t • wilderness, a prime example-require that trees be left alone to pursue their' OWII destiny. -

López-Sampson : Email: [email protected]; [email protected]. Lead of the study INTRODUCTION 2. Agroforestry options for enrichment on tobacco farms • Deforestation and land uses change have decreased the provision of timber-based products worldwide (Butler 2009, • 48% of the farmers showed interest in planting timber trees on their farms while 52% are not willing to plant timber FAO 2009, Grimm et al. 2008) trees. • Timber is widely used in tobacco industry mainly in the processing of tobacco leaves. • Important to explore opportunity to integrate timber trees on tobacco farms. Agroforestry can be an option. • Of the 4 species proposed (all non-natives), Eucalyptus camaldulensis had the highest rank on preference/acceptance (33% of farmers) whereas Acacia Mangium was the species with the lowest acceptance (19%) • We identified the opportunities to integrate timber trees in agricultural lands and tobacco farmers perception on timber (Table 4). tree planting. METHODOLOGY • Eucalyptus camaldulensis preference was due to the rapid growth of the species, good form and strength. • 44 farmers who have land titles participated in the study (Snowball approach). • Gliricidia sepium was the species with the highest acceptance (33%) for linear planting, followed by E. camaldulensis • This study was carried out in the municipality of Villa González, located in the flat areas in the South of the hills of the and P. caribaea. While Acacia mangium had the lowest acceptance among tobacco farmers for linear planting (13%). -

Allometric Equations for Four Valuable Tropical Tree Species Thomas G
Forest Ecology and Management 229 (2006) 351–360 www.elsevier.com/locate/foreco Allometric equations for four valuable tropical tree species Thomas G. Cole, John J. Ewel * USDA Forest Service, Pacific Southwest Research Station, Institute of Pacific Islands Forestry, 60 Nowelo Street, P.O. Box 4370, Hilo, HI 96720, USA Received 22 March 2005; received in revised form 7 April 2006; accepted 8 April 2006 Abstract Four tree species were harvested periodically over a 13-year period from plantations in the humid lowlands of Costa Rica: Cedrela odorata, Cordia alliodora, Hyeronima alchorneoides, and Euterpe oleracea. The soil was a well-drained, volcanic alluvium, and high fertility coupled with 4 m of annual rainfall and high temperatures led to rapid growth rates; at age 13 many individual were >30 cm dbh and >30 m tall. Harvested trees were dissected into their component parts: leaves, rachises (for Cedrela and Euterpe), branches, boles, and coarse roots (i.e., >0.5 cm diameter). Roots of small trees were excavated in their entirety; those of large trees were harvested from a cylinder 1.0 m in diameter, immediately beneath the trunk. Large numbers of trees were sampled: 258–379 per species. Size classes sampled ranged from seedlings too small to have a dbh to trees of 30 cm dbh. Two separate allometric equations (one for trees having only a basal diameter and another for trees having a dbh), with diameter- squared times height as the metrics, were developed for each component of each species. Based on breaks in linear trends of ln–ln plots and deviations of predicted from actual values, we developed separate allometric equations, by component, for trees of different sizes. -

Thenkabail Received: 11 December 2014 / Accepted: 17 March 2015 / Published: 1 April 2015 Abstract: The mission of this study is to compare Net Primary Productivity (NPP) estimates using (i) forest inventory data and (ii) spatio-temporally continuous MODIS (MODerate resolution Imaging Spectroradiometer) remote sensing data for Austria. While forest inventories assess the change in forest growth based on repeated individual tree measurements (DBH, height etc.), the MODIS NPP estimates are based on ecophysiological processes such as photosynthesis, respiration and carbon allocation. We obtained repeated national forest inventory data from Austria, calculated a “ground-based” NPP estimate and compared the results with “space-based” MODIS NPP estimates using different daily climate data. -
The Effect of Tree Crown Allometry on Community Dynamics in Mixed
Article The Effect of Tree Crown Allometry on Community Dynamics in Mixed-Species Stands versus Monocultures. A Review and Perspectives for Modeling and Silvicultural Regulation Hans Pretzsch Centre of Life and Food Sciences Weihenstephan, Technical University of Munich, Hans-Carl-von-Carlowitz-Platz 2, 85354 Freising, Germany; [email protected]; Tel.: +49-8161-71-4710 Received: 14 August 2019; Accepted: 11 September 2019; Published: 17 September 2019 Abstract: Many recent studies have shown that the structure, density, and productivity of mixed-species stands can differ from the weighted mean of monospecific stands of the respective species. The tree and stand properties emerging by inter-specific neighborhood should be considered in models for understanding and practical management. A promising approach for this is a more realistic representation of the individual tree allometry in models and management concepts, as tree allometry determines many structural and functional aspects at the tree and stand level. Therefore, this paper is focused on the crown allometry in mixed and mono-specific stands. Firstly, we review species-specific differences in the crown allometry in monospecific stands. Secondly, we show how species-specific differences and complementarities in crown allometry can emerge in mixed-species stands. Thirdly, the consequences of allometric complementarity for the canopy packing density will be analyzed. Fourthly, we trace the crown allometry from the tree level to the stand density and show the relevance for the self-thinning in mixed versus monospecific stands. Fifth, the consequence of the findings for modeling and regulating tree and stand growth will be discussed. The review deals mainly with widespread even-aged, mono-layered stands, but the main results apply for more heterogeneous stands analogously.
