“…Widespread fires are thought to be more ecologically important because of the extent of the effects. Too few fire-scarred trees were present on the landscape and/or collected to confidently allow plot-based fire interval analysis (e.g., Iniguez et al, 2008). In addition, high severity fire in parts of the MC forest killed and burned evidence of prior fires at individual plots, so fire dates from all plots were combined to make a site composite for each forest type (Dieterich, 1980).…”

“…In the topographically complex mountains of the semi-arid southwestern U.S., elevation and aspect can be important variables mediating vegetation type (e.g., Whittaker and Niering (1965)) and fire regimes (e.g., Iniguez et al (2008)). To ensure that the distribution of aspect class (N, S, E, W) at our gridded, age structure transects was proportional to the relative abundance of aspect classes in the study area we stratified the sampling grid by aspect class.…”

“…En ecosistemas mediterráneos el fuego es un factor natural con influencia en la productividad biológica y composición vegetal (Iniguez et al 2008). Postincendio y tras el deterioro y pérdida de vegetación se generan espacios abiertos donde se activa la germinación del banco de semillas, así como el rebrote de individuos de especies pre-existentes (Calvo et al 2008, Weiguo et al 2008, Vidal & Reif 2011.…”

Regeneración posincendio de plantas leñosas en plantaciones de ABSTRACTWe evaluated the regeneration of woody species in Pinus radiata plantations. The objective was to determine the recovery of vegetation from fires. The results indicated that 93% of the species are resprouters already present in the site before the fires. The most representattive familia were Anacardiaceae, Fabaceae and Rosaceae. Considering frecuency, coverage and relative density, the most important species are: Lithrea caustica, Schinus polygamus and Kageneckia oblonga. Lithrea caustica was the species that generated a great amount of sprouts some of them reaching to 95 cm. There was no regeneration of P. radiata but it may be only a matter of time.

“…Both fire and erosion are controlled by climate to various extents (Imeson and Lavee, 1998;Neary et al, 1999;Riebe et al, 2001). Watershed size and topography (Liu et al, 2003;Iniguez et al, 2008), in addition to the amount, intensity, and temporal distribution of precipitation can influence the rate of bulk SOM and PyC loss from or redistribution within an eroding watershed (Nearing, 1998;Cain et al, 1999;Rumpel et al, 2009). These relationships have been documented by many erosion prediction models, such as the Universal Soil Loss Equation (Wischmeier andSmith, 1965, 1978) and the Water Erosion Prediction Project (WEPP) model, which were originally developed in agricultural soils (Laflen et al, 1991).…”

Pyrogenic Carbon Erosion: Implications for Stock and Persistence of Pyrogenic Carbon in Soil

Pyrogenic carbon (PyC) constitutes an important pool of soil organic matter (SOM), particularly for its reactivity and because of its assumed long residence times in soil. In the past, research on the dynamics of PyC in the soil system has focused on quantifying stock and mean residence time (MRT) of PyC in soil, as well as determining both PyC stabilization mechanisms and loss pathways. Much of this research has focused on decomposition as the most important loss pathway for PyC from soil. However, the low density of PyC and its high concentration on the soil surface after fire indicates that a significant proportion of PyC formed or deposited on the soil surface is likely laterally transported away from the site of production by wind and water erosion. Here, we present a synthesis of available data and literature to compare the magnitude of the water-driven erosional PyC flux with other important loss pathways, including leaching and decomposition, of PyC from soil. Furthermore, we use a simple first-order kinetic model of soil PyC dynamics to assess the effect of erosion and deposition on residence time of PyC in eroding landscapes. Current reports of PyC MRT range from 250 to 660 years. Using a specific example-based model system, we find that ignoring the role of erosion may lead to the under-or over-estimation of PyC MRT on the centennial time scale. Furthermore, we find that, depending on the specific landform positions, timescales considered, and initial concentrations of PyC in soil, ignoring the role of erosion in distributing PyC across a landscape can lead to discrepancies in PyC concentrations on the order of several 100 g PyC m −2 . Erosion is an important PyC flux that can act as a significant control on the stock and residence time of PyC in the soil system.
