“…In this study we did not take into account the carbon biomass of understory and litter as they represent a small fraction of the total carbon in most forests (Brown 2002). Because we did not have data available for estimating carbon biomass in soils, it was not considered in this study despite the high importance of soil carbon (Liski et al 2006). The review of Nave et al (2010) showed a significant decrease in soil carbon following harvesting.…”

Human well-being highly depends on ecosystem services and this dependence is expected to increase in the future with an increasing population and economic growth. Studies that investigate trade-offs between ecosystem services are urgently needed for informing policy-makers. We examine the trade-offs between a provisioning (revenues from timber selling) and regulating (carbon storage and sequestration) ecosystem services among seven alternative forest management regimes in a large boreal forest production landscape. First, we estimate the potential of the landscape to produce harvest revenues and store/sequester carbon across a 50-year time period. Then, we identify conflicts between harvest revenues and carbon storage and sequestration. Finally, we apply multiobjective optimization to find optimal combinations of forest management regimes that maximize harvest revenues and carbon storage/sequestration. Our results show that no management regime alone is able to either maximize harvest revenues or carbon services and that a combination of different regimes is always necessary. We also show that with a relatively little economic investment (5% decrease in harvest revenues), a substantial increase in carbon services could be attained (9% for carbon storage; 15-23% for carbon sequestration). We conclude that it is possible to achieve win-win situations applying diversified forest management planning at a landscape level.

“…Using yield tables for a regional scale (Kurz et al, 2009) or quantifying the site index based on environmental factors (Nothdurft et al, 2012;Wang and Klinka, 1996) will help constrain the uncertainties associated with estimating a site index. To enable more precise and comprehensive assessment of South Korean forest C cycles, some important influences on C balance, such as CO 2 fertilization (Bellassen et al, 2011;Luyssaert et al, 2010), N deposition (Luyssaert et al, 2010), leaching (Luyssaert et al, 2010;Piao et al, 2012), forest area changes (Liski et al, 2006;Nabuurs et al, 2003), and management and other disturbances (Jandl et al, 2007;Kurz et al, 2009;Liu et al, 2002;Luyssaert et al, 2010;Zhou et al, 2013) need to be considered.…”

Abstract.Forests play an important role in the global carbon (C) cycle, and the South Korean forests also contribute to this global C cycle. While the South Korean forest ecosystem was almost completely destroyed by exploitation and the Korean War, it has successfully recovered because of nationalscale reforestation programs since 1973. There have been several studies on the estimation of C stocks and balances over the past decades in the South Korean forests. However, a retrospective long-term study that includes biomass and dead organic matter C and validates dead organic matter C is still lacking. Accordingly, we estimated the C stocks and their changes of both biomass and dead organic matter C during the 1954-2012 period using a process-based model, the Korean Forest Soil Carbon model, and the 5th South Korean national forest inventory (NFI) report. Validation processes were also conducted based on the 5th NFI and statistical data. Simulation results showed that the biomass C stocks increased from 36.4 to 440.4 Tg C at a rate of 7.0 Tg C yr −1 during the period 1954-2012. The dead organic matter C stocks increased from 386.0 to 463.1 Tg C at a rate of 1.3 Tg C yr −1 during the same period. The estimates of biomass and dead organic matter C stocks agreed well with observed C stock data. The annual net biome production (NBP) during the period 1954-2012 was 141.3 g C m −2 yr −1 , which increased from −8.8 g C m −2 yr −1 in 1955 to 436.6 g C m −2 yr −1 in 2012. Because of the small forested area, the South Korean forests had a comparatively lower contribution to the annual C sequestration by global forests. In contrast, because of the extensive reforestation programs, the NBP of South Korean forests was much higher than those of other countries. Our results could provide the forest C dynamics in South Korean forests before and after the onset of reforestation programs.

“…One is based on biomass expansion factors (BEFs) ( Chhabra et al, 2002;Jalkanen et al, 2005;Lehtonen et al, 2004;Levy et al, 2004;Liski et al, 2006;Soares and Tomé, 2004) that convert stand volume to stand biomass. The other method is based on models that reflect the allometric relationship between tree biomass and tree variables.…”

One of several procedures for estimating carbon stocks in forests is the estimation of tree or stand biomass based on forest inventory data. The two approaches normally used to convert field measurements of trees to stand biomass values are allometric biomass equations and biomass expansion factors (BEFs). BEFs are used in published National Forest Inventory results in which biomass is not estimated or as a complement of growth models that do not include biomass predictions. In this paper, the effectiveness of BEFs for estimating total stand biomass in Portuguese Eucalyptus globulus plantations was analyzed. Here, BEF is defined as the ratio of total stand biomass (aboveground biomass plus root biomass) to stand volume with bark. To calculate total biomass, an equation was developed to estimate root biomass as a function of aboveground biomass. Changes of BEF with stand variables were analyzed. Strong relationships were observed between BEF and stand age, stand basal area, stand volume and dominant height. Consequently, an equation to predict BEF as a function of stand variables was fitted, and dominant height was selected as the predictor stand variable. Estimates of total stand biomass based on individual tree allometric equations were compared with estimates obtained with a constant BEF (0.77), used in the Portuguese National Inventory Report on Greenhouse Gases, and with estimates obtained using the dominant height-dependent BEF equation developed in this work. The BEF prediction model proposed in this work may be used to improve E. globulus Portuguese biomass estimates when tree allometric equations cannot be used.Key words: root biomass; aboveground biomass; biomass expansion factors; allometric equations. Resumen Factores de expansión de la biomasa de rodales de Eucalyptus globulus en PortugalEl objetivo es estimar las reservas de carbono en los bosques mediante la comparación de dos métodos: ecuaciones alométricas de biomasa y los factores de expansión de la biomasa (BEF). Las estimaciones de la biomasa total del rodal, basado en las ecuaciones alométricas de árboles individuales se compararon con las estimaciones obtenidas con unos factores de expansión constante de la biomasa (BEF) de 0.77, utilizados en el Informe del Inventario Nacional de Portugal de gases de efecto invernadero, y con las estimaciones obtenidas utilizando la ecuación de altura dominante de BEF desarrollada en este trabajo. En este trabajo se analizó la eficacia de la BEF para estimar la biomasa total del stand en portugués plantaciones de Eucalyptus globulus. Aquí, el BEF se define como el cociente de la biomasa total del stand (biomasa aérea más la biomasa de raíces), situándose el volumen con corteza. Para el cálculo de la biomasa total, se desarrolló una ecuación para estimar la biomasa de raíces en función de la biomasa sobre el suelo. Se analizaron los cambios de BEF con las variables del rodal. Se observó una gran relación entre el BEF y la edad del rodal, el área basal, el volumen y la altura dominante. Por lo tanto, ...
