Annual biomass production and amount of organic carbon in Abies koreana forest of subalpine zone at Mt. Halla^1a

Organic carbon distribution and cycling in the Quercus glauca forest at Gotjawal wetland, Jeju Island, Korea

“…It is probably because the leaf cycle of the Q. glauca forest is different from that of deciduous trees which mostly shed their leaves in fall. In 2012, the litter production of the Q. glauca forest was similar to that of deciduous trees in fall but this was likely caused by the typhoon; no typhoons landed in 2011 but typhoon 'Bolaven' landed in 2012 (Jang et al 2014).…”

Budget and distribution of organic carbon in Taxus cuspidata forest in subalpine zone of Mt. Halla

“…Abies koreana forest, distributed in subalpine zone of Mt. Halla, also showed similar pattern even though its L layer seem to have a lot of forest floor litter (Jang et al 2014). However, L layer was lower than F layer of Pinus densiflora forest in Mt.…”

“…Moreover, organic carbon distribution of Abies koreana forest in Mt. Halla was 48.74 ton C ha −1 and it was 41.17 ton C ha −1 in 2013 which was higher than T. cuspidata forest (Jang et al 2014). Low height is one of the characteristics of T. cuspidata forest in subalpine zone of Mt.…”

“…Similar result was observed from studies on Abies koreana and Pinus densiflora which are also coniferous trees. The composition varied for each plant community but leaves always had the highest ratio (Jang et al 2014;Jeong et al 2013). As result, we could see that deciduous trees litter and produce most litter in fall just like coniferous trees.…”

“…Halla was 49.53 ton C ha −1 20 cm −1 depth −1 which decreased with depth (Jang et al 2014). Generally, organic carbon of soil decreases with depth (Eswaran et al 1995).…”
