Biomass And Nutrient Cycling Of Natural Oak Forests In Korea

Biomass and production of a naturally regenerated oak forest in southern Korea

“…Overall pro- duction for the three stands was similar: 11.7, 12.6, and 11.1 Mg ha À1 year À1 for stands 1, 2, and 3, respectively (Table 3). These values were within the range of production (3.5-20.8 Mg ha À1 year À1 ) for oak forests in Korea (Son et al 2004b), and were very similar to 11.1 Mg ha À1 year À1 , the value estimated for a 36-yearold Q. mongolica stand in the region (Park and Moon 1994). The understory accounted for a large proportion of net total production for stand 1, which was 40.7%, compared to the 12.9 and 10.9% for stands 2 and 3.…”

“…The biomass for the three stands was similar to that typically found in this region for oak forests of comparable age. For example, Son et al (2004b) reported from a review of the literature a total biomass of 118-156 Mg ha À1 for 22-to 36-year-old oak forests. Stand 3 had the highest total biomass, and tree diameter and height seemed to account for the differences in biomass among the stands.…”

“…Relatively slow growth of oak trees in the overstory and greater light penetration onto the forest floor might influence the rapid growth of understory for the site (Son et al 2004a). There are only a few data on root biomass for oak species in literature (Son et al 2004b). However, the proportion of overstory root biomass to total overstory biomass ranged from 20.1% for stand 3 to 24.6% for stand 2 in this study.…”

Notes on the biomass expansion factors of Quercus mongolica and Quercus variabilis forests in Korea

“…mongolica and Q. variabilis are two of the most common oak species that are widely found in natural deciduous and mixed forests throughout Korea (Yi 2003, Son et al 2004a, 2007a, Park et al 2005a, Kwon and Lee 2006b) and play an important role in ecological, social and economic aspects in terms of increased biodiversity, cultural significance, and wood production across the country. Over the past several decades, data sets on biomass and productivity of Q. mongolica and Q. variabilis forests have been published with the large accumulation of field survey data (Song et al 1997, 2005a, Son et al 2004b).…”

Opportunities for implementing REDD+ to enhance sustainable forest management and improve livelihoods in Lombok, NTB, Indonesia

“…The proportion of understory biomass (woody plus herbaceous) to aboveground biomass (overstory plus understory) ranges from 1.2% to 6.3%, which is negatively correlated with total aboveground biomass. Son et al (2004) explained that light interception by overstory vegetation seems to influence production of understory vegetation.…”
