Global Carbon

It has been proposed that forests will act as a sink for -50% of the anthropogenic C02 projected to be released into the atmosphere by the year 2050 as global net primary productivity in forests increases (DeLucia et al. 1999). Coniferous forest ecosystems dominate a large portion of the Earth's land area, and fire plays an important role in the natural disturbance regime of these ecosystems (Archibald 1995). Quantifying the components of the carbon cycle during ecosystem recovery from fire is fundamental for determining how fire and changes in fire frequency alter regional and global carbon budgets (Auclair and Carter 1993, Houghton 1996, Burke et al. 1997). Clearly, if we are to model the effects of terrestrial ecosystems on global carbon budgets, we must develop a better understanding of the role that natural disturbance plays in the carbon dynamics of these systems. Processes that occur after fire may be more important for carbon cycling than the immediate return of carbon to the atmosphere through biomass oxidation (Auclair and Carter 1993). For example, primary productivity following fire is reduced or eliminated until new chlorophyll is synthesized in new leaf area. In addition, aboveground detrital inputs are greatly altered and formerly live roots become available for decomposition. Moreover, litter quality changes with the oxidation of fine fuels; soils and litter become warmer with the removal of overstory shading and a change in albedo; and soils become wetter because of essentially no post-fire transpiration and very little interception of rain and snow. These changes can increase decomposition and soil respiration (Burke et al. 1997), releasing as much as three times more carbon to the atmosphere as the amount released by the initial fire (Auclair and Carter 1993). Notably, carbon is assimilated by new plant growth in fire-adapted ecosystems, with perhaps little net effect on atmospheric C02 (Crutzen and Goldhammer 1993). In addition to large effects on carbon budgets at the stand scale, fire and landscape variables interact to produce a mosaic of different vegetation types (Anderson and Romme 1991, Turner et al: 1997a and b, Foster et al. 1998). The resulting spatial heterogeneity in tree density, herbaceous cover, and species composition in Yellowstone National Park (YNP) will influence primary production and carbon storage for many years. Therefore, to determine the long-term effects of fire on carbon release and storage following fire, information is needed on how processes differ among sites as a function of community structure and stand age. YNP is an ideal study area for this kind of research. Our objective is to answer two questions: 1) How does the relative abundance of trees, shrubs, and herbs influence above- and belowground carbon storage and flux values in young post-fire stands? 2) How do above- and belowground carbon storage and fluxes in young post-fire stands differ from those in nearby mature forests?

Experimental Burns

AbstractEthiopia aims to restore 15 million ha degraded forests and woodlands, but effects on the potentially contrasting goals of long-term carbon storage, biodiversity and sustainable livelihoods are unknown. To quantify the effects of grazing exclusion on vegetation and fire behaviour, we established six 30 × 30 m fenced exclosures with grazed controls, in a mesic wooded savanna. Experimental burns were done after 1.5 years. Tree seedlings were few but more common inside fences. Field layer cover and biomass increased inside fences, and grass species increased in numbers and cover. Fire intensity was higher inside fences, killing shrubs and saplings but not mature trees. Interviews confirmed that overgrazing has resulted in “cool fires”, causing shrub encroachment. High-intensity fires occurred in the 1980s after a zoonotic disease killed most livestock. Short-term increase in carbon storage through fire and grazing exclusion may lead to loss of pasture, and in the long-term increased wildfire risk.

AbstractHenan was the site of development for several ancient cultures during the Holocene. In this study, black carbon (BC) in the Holocene sediment is compared with known climatic changes and cultural events to provide information concerning the link between fire, climatic changes, and human activity in Xiangcheng. Prior to 8000 cal yr BP, the occurrence of fires was low under cold and dry climatic conditions. The BC content in 8000–1000calyrBP indicates a gradual increase in fire, with two peak values at 7500calyrBP and 3500 cal yr BP. The first peak correlates to the development of the Peiligang culture, and the second peak correlates to the development of wet and warm climate conditions along with the appearance of the Xia–Shang dynasties. Increases in fire activity could therefore be attributed to climate change and the development of human civilization in the region. Another sharp increase in fires around 1000calyrBP was consistent with a sharp increase in population during the Tang dynasty.
