“…These results may be attributed to the mortality of large canopy trees of P. koraiensis, which may be caused by natural mortality or by the infection of fungal pathogens. The mortality of P. koraiensis created canopy gaps, facilitating the recruitment of light-demanding species into the space under the canopy gap, and increasing the stand density and species richness in such plots (Shirima et al 2014). The recruited individuals generally were smallsized trees and had a low C storage.…”

How stand density and species richness affect carbon (C) storage and net primary productivity (NPP) changes with forest succession is poorly understood. We quantified the C storage of trees and the aboveground NPP in an early successional secondary birch forest (birch forest) and a late successional mixed broadleaf‐Korean pine (Pinus koraiensis) forest (mixed forest) in northeastern China. We found that: 1) tree C storage in the mixed forest (120.3 Mg C ha−1) was significantly higher than that in the birch forest (78.5 Mg C ha−1), whereas the aboveground NPP was not different between the two forest types; and 2) only stand density had a positive linear relationship with tree C storage and aboveground NPP in the birch forest. In the mixed forest, both tree C storage and aboveground NPP were significantly affected by the combination of the stand density and species richness. The tree C storage to stand density and species richness relationships were hump‐shaped. The aboveground NPP increased with increasing stand density, but its relationship to species richness was hump‐shaped. We conclude that the effect of stand density and species richness on tree C storage and aboveground NPP was influenced by forest stand succession, and such effects should be considered in studying stand density‐ and species richness‐ ecosystem function (e.g., C storage and NPP) relationships in temperate forest ecosystems.

“…Hence, improving the management of forest resources to sequester CO 2 is a prompt strategy to reduce greenhouse gases, which has been justified as a potential measure for climate change mitigation. Trees play major roles in carbon storage and forest ecosystem functioning (Shirima et al, 2015), as they trap the atmospheric carbon and convert it in to plant biomass (Ravindranath et al, 1997). It is important to measure tree biomass of a region to determine its carbon stock, and there are two types of assessment method, 1) direct method through destructive sampling (felling of trees) (Brown et al, 1989) and 2) indirect method by applying allometric equation using tree mensuration data.…”

“…Hence, it is most important to understand the dynamics of carbon stocks in relation to the key factors for sustainable management of forest carbon sinks. To my knowledge, only a few studies have focused on how species richness, density, and altitude are influencing on forest carbon stocks (Aryal et al, 2018;Mwakisunga & Majule, 2012;Nakakaawa et al, 2010;Sharma et al, 2018;Shirima et al, 2015). Further, no similar study was undertaken in Pachaimalai tropical hill forest (PTHF) in India so far.…”

The present study was carried out to understand the relationship of tree carbon stock to key factors such as species richness, density and altitude, in Pachaimalai tropical hill forest located in Tamil Nadu, India. The study area (PTHF) was parted into 24 6.25 km × 6.25 km grids, and at each grid, all live trees ≥30 cm girth at breast height were recorded from a randomly placed 0.5 ha transect. The total carbon stock estimated for the PTHF ranged from 4.79 to 119.00 t ha −1 (n = 24). The species richness, density, and altitude ranged from 12 to 38 species T −1 , 260 to 696 trees ha −1 and 209 to 825 m asl, respectively. Regression analysis revealed that the total carbon stock had a significant positive relation with species richness (r 2 = 0.703) as well as with altitude (r 2 = 0.767), and it had no significant relation with tree density. Understanding the dynamics of tree carbon stocks in relation to key factors is of prime need for sustainable management of forest carbon sinks, and the present study provides valuable information for carbon stock management in PTHF ecosystem, and further it may help to develop testable hypotheses on other tropical forests.

“…For soils, Lange et al (2015) found that elevated carbon storage at sites with high plant diversity is directly related to the soil microbial functional community (i.e., soil biodiversity), which in turn is related to plant species richness, suggesting that soil carbon storage is mainly limited by the integration of new carbon into soil and less by the decomposition of existing soil carbon. In many studies in tropical forests, planted forests and second growth forests-which often lack species with high wood density, and generally have lower taxonomic diversity than primary forests-there is typically lower biomass stored in live and dead biomass pools (Cavanaugh et al 2014;Gonzalez et al 2014;Osuri et al 2014;Shirima et al 2015). Single species plantations result in reduced litter, or recalcitrant litter, followed by depletion of soil biodiversity and as a consequence less stored soil carbon (de Vries et al 2013;Zhao et al 2013;Aslam et al 2015).…”

Forest biodiversity, ecosystem functioning and the provision of ecosystem services

Forests are critical habitats for biodiversity and they are also essential for the provision of a wide range of ecosystem services that are important to human well-being. There is increasing evidence that biodiversity contributes to forest ecosystem functioning and the provision of ecosystem services. Here we provide a review of forest ecosystem services including biomass production, habitat provisioning services, pollination, seed dispersal, resistance to wind storms, fire regulation and mitigation, pest regulation of native and invading insects, carbon sequestration, and cultural ecosystem services, in relation to forest type, structure and diversity. We also consider relationships between forest biodiversity and multifunctionality, and trade-offs among ecosystem services. We compare the concepts of ecosystem processes, functions and services to clarify their definitions. Our review of published studies indicates a lack of empirical studies that establish quantitative and causal relationships between forest biodiversity and many important ecosystem services. The literature is highly skewed; studies on provisioning of nutrition and energy, and on cultural services, delivered by mixed-species forests are under-represented. Planted forests offer ample opportunity for optimising their composition and diversity because replanting after harvesting is a recurring process. Planting mixed-species forests should be given more consideration as they are likely to provide a wider range of ecosystem services within the forest and for adjacent land uses. This review also serves as the introduction to this special issue of Biodiversity and Conservation on various aspects of forest biodiversity and ecosystem services.
