“…Scott & van Wyk 1990;Crockford et al 1991) have shown a correlation between water repellency and litter quality, implying higher water repellency on sites with 'ecologically less favorable' humus forms (e.g. moder and mor-like forms), in this case represented by the plots M and S. Higher water repellency under mor-type humus forms compared to other humus forms are also reported by Sevink et al (1989) and Imeson et al (1992). Ziegler and Zech (1989) and Dinel et al (1990) report the concentration of hydrophobic lipid compounds to decrease with increasing efficiency of decomposition.…”

Soil water repellency has important consequences for ecological and hydrological properties of soils and usually retards infiltration capacity and induces preferential flow. This phenomenon has been known to occur on a wide range of sites under a variety of climatic conditions. The objective of this study was to investigate and characterize soil water repellency on forest sites with identical substrate and climatic conditions, differing in tree age and species. In the Vester Torup Klitplantage, an area comprising a conifer dominated forest plantation stocking on sandy deposits in a coastal setting near the Jammer Bay in north-western Jutland/Denmark, four different forest plots were investigated for water repellency effects four times in 2005. To measure soil water repellency, the water drop penetration time test and the critical surface tension test were carried out. Both tests revealed a seasonal variability in water repellency, exhibiting the highest water repellency for the upper 10 cm of the soil during the summer months, whereas the variability between the different plots seems to be less significant. There was no coherence between humus forms, thickness of litter layer and water repellency.

“…The dispersion of permeability values corresponds to the typical situation observed in this soil property (Hillel, 1998). The decrease of the permeability immediately after fire with respect to pre-fire situation is widely referenced in literature, and in general it is attributed to soil hydrophobicity generated by lipid compounds released from burnt plant material, whose persistence in the soil is very variable, depending on fire severity and environmental conditions after fire (Imeson et al, 1992;Hubbert et al, 2006;Are et al, 2009;Woods and Balfour, 2010). The high mean permeability values, and even the median, show that this effect was no more evident in the study area two months after fire.…”

“…The extent and duration of fire effects on soil properties depend on fire behaviour, especially related to fire severity, as well as on post-fire weather conditions, mainly the characteristics of subsequent rainfall events (de Luís et al, 2001;Certini, 2005;Francos et al, 2016). A direct effect of fire on soil surface is the formation of a continuous water-repellent film, which reduces permeability and increases runoff (Imeson et al, 1992). In Mediterranean ecosystems, where the torrential rainfall events are frequent in autumn and winter, October to March is a critical period when soil susceptibility to water erosion processes is increased after the summer wildfires (Andreu et al, 2001;Fonseca et al, 2011;Francos et al, 2016).…”

“…Therefore, one reason of the enhanced soil erosion after the 2003 fire is the soil surface morphological change that reduced the litter and aboveground standing biomass (Imeson et al, 1992). This fact, together with the high rainfall intensity and the short time between the fire and heavy storms were the key factors of the increased runoff and sediment production.…”

The effect of a repeated burning on soil hydrology and erosive parameters was studied on a Mediterranean forest soil (Rendzic leptosol) with the aim of identifying the effects of the fire and climatic parameters related to the post-fire runoff and soil loss. The study was carried out in an Experimental Permanent Field Station (La Concordia), close to Valencia (Spain).This field station is located on a calcareous hillside facing SSE, and is comprised of nine erosion plots (20×4 m). Firstly, experimental fires were performed in June 1995 with two fire treatments (T1 or high severity fire and T2 or moderate severity fire) and a control one Fire effects were reflected in the erosion rates. Soil losses prior to the 2003 fire, in both fire treatments and in the control one, were scant relative to post-fire levels. However, six months after the repeated fire (period II) and almost one year later (period IV), soil losses increased into two orders of magnitude coinciding with the post-fire bare soil augment. The repeated fire impact and rainfall intensity magnified runoff and soil loss. Significant linear relationships between rainfall intensity, runoff and soil loss, were obtained for the burned plots. In the Comentario [o1]:It is not good to include four paragraphs in an abstract like this. I think two is maximum, so I connected the first and second, and the third and fourth paragraphs. 3 60 burned areas, rain intensities increased to 20 mm h -1 augmenting the runoff and soil loss in one and two orders of magnitude, respectively.
