“…Mulch strips at the bottom of small laboratory soil flumes effectively reduced 50% the interrill erosion, with application rates of only 0.8 and 0.2 Mg ha -1 of, respectively, forest residue and straw mulch (see Abrantes et al, 2018;Prats et al, 2017). These findings should be incorporated into erosion models to help managers to select the target areas as it was done in the case of Portugal (Vieira et al, 2014. Plot aspect can be used as an indicator for selecting intervention areas in the Mediterranean region (Badía et al, 2015;Cerdà et al, 1995;Marques and Mora, 1998).…”

Mulching with forest residues has proved to be highly effective in reducing post‐fire soil losses at the plot scale. However, its effectiveness has not been quantified at the application rates that are typically used in operational post‐fire land management (2–3 Mg ha‐1 using straw), as well as at scales larger than 100 m2. The present study compared post‐fire erosion rates for six convergent hillslopes or swales of 500 to 800 m2, three of which were left untreated while the other three were mulched immediately after the fire with shredded eucalypt bark at a rate of 2.4 Mg ha‐1. Erosion rates were monitored at irregular intervals during the first three post‐fire years, whilst ground cover was assessed yearly. Selected topsoil properties (0–2 cm) such as organic matter content and aggregate stability were determined at a single occasion – two years after the wildfire, for three micro‐environments separately: bare soil, and under mulch/litter and vegetation. Soil losses on the untreated swales decreased with post‐fire year from 2.2 to 0.4 and 0.11 Mg ha‐1 yr‐1 (respectively for the first, second and third post‐fire years), while the mulched swales produced 84%, 77% and 38% less soil losses than the untreated swales. Soil losses also depended on slope aspect, with the north‐facing swales producing less erosion than the west‐facing ones. This could be linked to their significant differences in bare soil, vegetation and stone cover, or a combination thereof. The type of micro‐environment also played a significant role in topsoil properties (stone content, bulk density, resistance to penetration/shear stress, porosity and organic matter content). The present results add to the increasing evidence that forest residues should be duly considered for operational post‐fire land management. Forest residues were highly effective in reducing erosion from swales at application rates as low as the typical 2 Mg ha‐1 of post‐fire straw mulch. © 2019 John Wiley & Sons, Ltd. © 2019 John Wiley & Sons, Ltd.

“…Eucalypt soils in the region are well-known to develop extreme water repellency during the dry summer season (e.g., Doerr et al, 2000;Ferreira et al, 2000;Keizer et al, 2008;Santos et al, 2013). Santos et al (2013) and Vieira et al (2014) emphasize that addressing soil hydrophobicity in hydrological/erosion models may potentially improve the understanding of the process of infiltration, wetting-up and breaking of soil water repellency after the summer season. SWAT may be underestimating infiltration capacity during the dry season, suggesting that the curve number method for surface runoff generation could be adapted to account for preferential flow following dry weather conditions.…”

“…However, the impact of LULCC on evapotranspiration increases as catchment area decreases, and the incorporation of vegetation effects is expected to enhance the prediction of the hydrological response capacity (Donohue et al, 2007;Peel et al, 2010). A growth in forest cover usually has a negative effect on the water yield (Sahin and Hall, 1996;Andréassian, 2004;Farley et al, 2005;Chappell and Tych, 2012;Brown et al, 2013), whereas a decrease in forest cover increases runoff and associated risks of floods and soil erosion (Anderson et al, 1976;Leyer et al, 2012;Vieira et al, 2014). Vegetation type and cover are also an important factors explaining streamflow changes.…”
