Stas and published by CIFOR. This book was released on 2014-12-12 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The loss of ecosystem services due to deforestation is of global concern. Financial mechanisms such as REDD+ (reducing emissions from deforestation and forest degradation) have been proposed as ways to support the conservation of tropical forests. Crucial steps in the implementation of REDD+ are to estimate national-level carbon emissions from deforestation and forest degradation and to collect data on local biomass and carbon stocks. In this research, above-ground biomass (AGB) values and associated carbon stocks in a lowland secondary forest are estimated and compared with those in an adjacent primary forest, both growing on limestone in Seram, the Moluccas, Indonesia.

Available in PDF, EPUB and Kindle. Book excerpt: Forests grow and their biomass increases; they absorb carbon from the atmosphere and store it in plant tissue. Understanding the biomass of forest vegetation is essential for determining the storage of carbon in the dominant tree component and computing carbon cycling at a regional as well as global level. This book consisting of five chapters will give a comprehensive understanding of biomass production vis-à-vis carbon storage in relation to litter and nutrient dynamics of the forest by analyzing the mode and magnitude of biomass production and carbon storage as a function of various silvicultural factors.

This book was released on 2008 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon sequestration in tropical secondary forests growing in all climates must be quantified to understand their potential role in adaptation and mitigation strategies of global climate change. Total aboveground biomass (TAGB), soil carbon, and total ecosystem carbon (TEC) were measured in 54 secondary forests growing along a broad bioclimatic gradient of 6 life zones, from lowland Dry to Premontane Rain forests in Costa Rica. The potential of regenerating secondary forests to offset carbon losses due to climate change-mediated primary forest degradation into the year 2100 was also determined. TAGB ranged from 12 Mg·ha−1 (5 MgC ha−1) in a 9-yr. Dry forest to 298 Mg·ha−1 (143 MgC ha−1) in a 60-yr Wet forest. TAGB and carbon were correlated with forest age and the ratio of potential evapotranspiration to precipitation. Secondary forests were predicted to reach TAGB >_ 90% of that in primary forest in 35 to 126 yrs. Mean soil carbon to 1 m ranged from 127 to 278 Mg·ha−1 in the Dry and Premontane Rain life zones. There was no correlation of soil C pools with age. TEC was as high as 440 Mg·ha−1 in a 40-yr Premontane Rain forest. Maximum rates of TEC sequestration were highest (14 - 33 Mg·ha−1 yr−1) in life zones with intermediate levels of precipitation and lowest (7 and 12 Mg·ha−1 yr−1) in the Dry and Premontane Rain life zones. Secondary forests were predicted to attain ecosystem C levels similar to that of primary forests in 44 - 105 yrs. Based upon simulations of forest growth and the changing land area covered by differing life zones due to climate change, carbon losses from primary forests ranged from

Available in PDF, EPUB and Kindle. Book excerpt: Until recently, large-scale assessments and country-level reporting of forest carbon stocks and sinks have been relying on coarse estimates provided in 2006 by the Intergovernmental Panel on Climate Change (IPCC). However, these estimates were based on a handful of studies per global ecological zone (also known as ecozone), did not provide methods for their derivation nor measures of uncertainty, and did not distinguish between forest successional stages.

Available in PDF, EPUB and Kindle. Book excerpt: The Carbon Balance of Forest Biomes provides an informed synthesis on the current status of forests and their future potential for carbon sequestration. This volume is timely, since convincing models which scale from local to regional carbon fluxes are needed to support these international agreements, whilst criticisms have been levelled at existing empirical approaches. One key question is to determine how well eddy-flux measurements at the stand-level represent regional-scale processes. This may be related to specific management practices (age, plantation, fertilisation) or simple bias in choosing representative sites (ease of access, roughness, proximity to physical barriers). The ecology and regeneration state of temperate, tropical and boreal forests under current climatic conditions are discussed, together with partitioning of photosynthetic and respiratory fluxes from soils and vegetation. The volume considers how to integrate contrasting methodologies, and the latest approaches for scaling from stand to the planetary boundary layer.

Book excerpt: Research Paper (undergraduate) from the year 2023 in the subject Geography / Earth Science - Physical Geography, Geomorphology, Environmental Studies, grade: 3.63 (B+), language: English, abstract: This review presents a systematic review on the Biomass Carbon Stock Estimation Options for Trees and Forests Resources within and around Mago National Park, Southern Region of Ethiopia. In order to review and gain information from existing research on types of forest, basal area, biomass/carbon stock, sequestration pool in different forest ecosystems of Mago National Park, a literature research was carried out during January 2022 to October 2022 using Web of Science, Google Scholar Citation, Research Gate, IPCC, United Nations Framework Convention on Climate Change (UNFCCC) and REDD+ report, offline journals, book chapters, government scientific reports, Forest Survey data, Botanical Survey data, as well as reports published by Ministry of Environment, Forest and Climate Change. The review is limited to in and around Mago National Park forest ecosystem in relation to above and below biomass and carbon stock estimations. Formulating allometric equations for all woody plants in Ethiopia is quite desirable for accurately quantifying the biomass and carbon stock of forests to achieve accurate national and international reporting of carbon dioxide emission inventories. Depending on this in Ethiopia several studies undertaken regarding allometric equation for biomass estimation, but it is not as forest resource of the country. Most of the study undertaken was depend on semi-destructive method, which is not accurate as destructive measurement. Forests play an essential role as source and sink in the global carbon cycle. Development and other human induced activities have led to degradation of forest land, and ultimately, it results in loss of biodiversity and increases concentration of CO2 in atmosphere. Therefore, there is urgent need to estimate regional and national le
Download or read book Aboveground Carbon Storage and Net Primary Production in Human Impacted Forests Under Current and Future Climate Scenarios written by Jyh-Min Chiang and published by . This book was released on 2007 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forested ecosystems contain the largest terrestrial carbon pools and fluxes on earth. Thus, forest ecosystem disturbances can result in large perturbations in global carbon cycling and subsequently climate. The objective of my dissertation was to investigate the role of forest burning and thinning, changing climate, and changing species compositions on carbon cycling in a subset of forests in the eastern United States. I examined processes that influenced net primary production (NPP) of forested ecosystems at different scales: First, I examined the sensitivity of budburst phenology on simulations of NPP and, based on the Harvard Forest phenology database, I optimized a subroutine, which included a chilling factor, for the prediction of budburst dates. Budburst phenology was a sensitive variable in PnET model simulations but leaf-off date was not. The phenology subroutine, when applied to southern Ohio forests, exhibited geographic specificity, highlighting the importance of local phenological data. Second, I examined the effects of mechanical thinning, prescribed burning, and multiple environmental factors on specific leaf weight (SLW) and leaf nitrogen content (Nmass) of seven common tree species. Increases in both leaf traits were positively associated with increases in potential NPP. Thinning increased SLW at the lower canopy by 22% and resulted in an 8% increase of modeled NPP. The effects of burning were not significant. Variations of both leaf traits were primarily explained by species differences. Third, I assessed the impacts of thinning and burning on aboveground carbon stocks and NPP using both field measurements and PnET model simulations in southern Ohio. Only thinning affected NPP (> -30%); however, the thinning effect on NPP was transient (1-2 years) according to both field and model results. Lastly, at a larger spatio-temporal scale, I used the PnET-II model to simulate the NPP consequences of potential tree species redistribution and future climate in four selected focal areas (40,000 km2 each). The effects of potential species redistribution predicted in 2100 had moderate effects (-12% to 8%) on NPP compared to the impacts of future climatic change (-60% to 25%). As increasing temperatures negatively impact NPP, the reduction in forest carbon uptake capacity could accelerate changing climate.

Download or read book Long Term Forest Carbon Storage and Structural Development as Influenced by Land Use History and Reforestation Approach written by Andrea R. Urbano and published by . This book was released on 2016 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Temperate forests are an important carbon sink, yet there is uncertainty regarding land-use history effects on biomass accumulation and carbon storage potential in secondary forests. Understanding long-term biomass dynamics is important for managing forests as carbon sinks and for co-benefits such as watershed protection and biodiversity. However there are many unanswered questions regarding these dynamics in northeastern U.S. forests: How have secondary forests of the U.S. Northeast recovered post nineteenth century agricultural abandonment? How has the region’s extensive land-use history influenced long-term structural development and aboveground carbon storage? To answer these questions, we employed a longitudinal study based on twelve years of empirical data (2001-2013) from the Marsh-Billings-Rockefeller (MBR) National Historical Park in Woodstock, VT. MBR Park was the first parcel of land to actively be reforested in the eastern U.S., and as such, its diverse forest mosaic reflects a history of alternate reforestation approaches and varied successional trajectories indicative of secondary forest recovery occurring across the broader northeastern forest landscape. We also used 150 years of documentary data from park management records. This research evaluates the effects of reforestation approaches (planting vs. natural regeneration), management regimes (long-term low-to-intermediate harvest intensities at varied harvest frequencies), and stand development pathways on biomass outcomes. We generated biometrics representative of stand structural complexity, including the H’ structural diversity index, and aboveground biomass (live trees, snags, and downed coarse woody debris pools) estimates. Multivariate analyses evaluated the predictive strength of reforestation approach, management history, and site characteristics relative to aboveground carbon pools and stand structural complexity. Classification and Regression Tree (CART) analysis ranked reforestation approach (plantation or natural regeneration) as the strongest predictor of long-term mean total aboveground carbon storage, while harvest frequency, and stand age were selected as secondary variables. CART ranked forest percent conifer (a metric closely associated with reforestation approach) as the strongest predictor of H’ index, while harvest intensity, and harvest frequency were selected as secondary variables. Increases in harvest intensity can significantly reduce aboveground carbon storage. Our results suggest that a variety of long-term recovery pathways converge on high levels of aboveground carbon storage, including both conifer plantations and naturally regenerated hardwood stands, but choice of silvicultural management approach can dramatically alter those trajectories. Importantly, total aboveground biomass (i.e., carbon) co-varied with H’ (r2 = 0.25), and thus, our dataset showed a positive relationship between forest carbon storage and structural complexity, supporting the concept of multifunctional forestry emphasizing late-successional habitats.
