“…High concentrations of wildfire PyC that become incorporated into the mineral soil over the longer term after fire may actually decrease C flux from the soil to the atmosphere. We note that vegetation recovery also has an important influence on post-fire C dynamics [50,51], and is not addressed by our study.…”

Pyrogenic carbon (PyC) is produced by the thermal decomposition of organic matter in the absence of oxygen (O). PyC affects nutrient availability, may enhance post-fire nitrogen (N) mineralization rates, and can be a significant carbon (C) pool in fire-prone ecosystems. Our objectives were to characterize PyC produced by wildfires and examine the influence that contrasting types of PyC have on C and N mineralization rates. We determined C, N, O, and hydrogen (H) concentrations and atomic ratios of charred bark (BK), charred pine cones (PC), and charred woody debris (WD) using elemental analysis. We also incubated soil amended with BK, PC, and WD at two concentrations for 60 days to measure C and N mineralization rates. PC had greater H/C and O/C ratios than BK and WD, suggesting that PC may have a lesser aromatic component than BK and WD. C and N mineralization rates decreased with increasing PyC concentrations, and control samples produced more CO2 than soils amended with PyC. Soils with PC produced greater CO2 and had lower N mineralization rates than soils with BK or WD. These results demonstrate that PyC type and concentration have potential to impact nutrient dynamics and C flux to the atmosphere in post-fire forest soils.

“…Forest carbon stocks typically increase with age until becoming relatively stable after 100 -150 years, while net ecosystem carbon balance often peaks much earlier and gradually declines to near zero (Pregitzer & Euskirchen, 2004;Bradford & Kastendick, 2010;Williams et al, 2012). Natural and anthropogenic disturbance events that alter forest stand structure influence site-level carbon stocks and fluxes (Kashian et al, 2006;Gough et al, 2007;Gough et al, 2008;Nave et al, 2010). Likewise, landscape to regional disturbance regimes or management strategies that alter forest diameter-class distributions over large areas will ultimately drive changes in carbon stocks at landscape to regional levels (Heath & Birdsey, 1993;Pregitzer & Euskirchen, 2004;Mouillot & Field, 2005;Birdsey et al, 2006;Depro et al, 2008;Scheller et al, 2011).…”

The structure and species composition of undisturbed natural forests serve as benchmarks for understanding forest carbon storage potential for reduced carbon emissions. Even though Kenya is seeking to stabilize forest cover, reverse degradation and increase forest cover through mechanisms such as REDD+, there is relatively little information on inherent forest carbon storage potential or its response to disturbance. Comparative studies were undertaken in three remnant fragments of indigenous forests in Taita Hills, Kenya to characterize the structure and forest carbon storage potential of undisturbed, moderately and heavily disturbed sites within these forests. The sensitivity of forest carbon storage estimates to different methods of tree biomass estimation were also examined, including estimates which used DBH, tree height and wood density from extracted tree cores. Disturbance altered the forest structure, reduced species diversity and decreased the capacity of the forests to sequester carbon. The forests' capacity to sequester carbon reduced by between 9.2% and 70.7% depending on the site (forest fragment) and level of disturbance. Models with DBH and wood density gave higher quantities of carbon of between 0.9% and 44.4% for sites exhibiting different levels of disturbance. The present results suggest that disturbance had strong influence on forest structure, species diversity and carbon stocks and therefore maintaining the forests' ecological integrity over the long-term may prove difficult if the frequency and intensity of disturbance increases. Moreover, development and implementation of effective mitigation strategies to reduce carbon emissions will require the use of local biomass models since they are accurate.

“…Carbon stored in forest ecosystems over the long term will be released rapidly and in considerable amounts into the atmosphere following disturbances (Page et al, 2002). Forest age (i.e., time since disturbances) and structure are critical factors determining forest ecosystem carbon storage and fluxes (Turner et al,1995;Caspersen et al, 2000;Law et al, 1999Law et al, , 2001Song and Woodcock, 2003;Litvak et al, 2003;Kashian et al, 2006). Many components of the forest carbon cycle are related to forest age, including biomass of coarse woody debris (BondLamberty et al, 2002), stand water use (Delzon and Loustau, 2005), soil carbon (Peltoniemi et al, 2004), live biomass increment and litter decomposition (Bradford et al, 2008), size structure (Sano, 1997;Hoshino et al, 2001), NPP (Gower et al, 1996;Ryan et al, 1997;Murty and McMurtrie, 2000;Chen et al, 2002), net ecosystem productivity (NEP)/net biome productivity (Litvak et al, 2003;Song and Woodcock, 2003), and biophysical properties .…”
