Abstract Forest fires can greatly increase runoff and surface erosion rates. Post‐fire soil control measures are intended to minimize this response facilitate ecosystem recovery. In a few recent cases, hydromulch has been applied, consists of mixture organic fibers, water seeds. The objectives research were (i) analyze the effectiveness in reducing post‐fire sediment production (ii) determine underlying processes mechanisms that erosion. After wildfire occurred August 2008, 14 plots ranging...
Abstract Besides direct damage, wildfires can produce striking and indirect impacts, including extreme runoff–erosion responses with serious negative consequences for land‐use sustainability downstream values at risk. The best way to reduce post‐fire runoff is the rapid application of mulch: a protective cover straw, needles, wood‐based material, or other ground cover. In this study, we assessed efficacy forest residue mulching reducing across spatial scales on logged burnt eucalypt...
Abstract The purpose of this study was to assess how terracing affected overland flow and associated sediment losses, at the micro-plot scale (0.25 m 2 ), in recently burnt stands two principal forest types north-central Portugal, i.e. mono-specific Maritime Pine Eucalypt. Terracing is an increasingly common practice slope engineering region but its impacts on runoff erosion are poorly studied. Non-terraced plots Eucalypt site revealed similar median coefficients (rc: 20-30%) as well...
Abstract Increases in post‐fire runoff and erosion have been reported worldwide, but little is known about the combined effect of wildfires pre‐existent ploughing operations. A previous study using simulated rainfall found a similar for an unploughed pre‐fire ploughed site, clearly showed lower site. This measured at same two sites, with experimental design, under natural conditions. Four micro‐plots were installed on each eucalypt stands, one which was rip‐ploughed 20 years before fire. The...
Abstract Soil water repellency (SWR) is a dynamic soil property that influences hydrology. The main goal of this work was to determine in situ spatial and temporal variations SWR six recently burnt eucalypt stands with different pre‐ post‐fire management. severity measured the field using “molarity an ethanol droplet test” during 1–2 years, at intervals weeks. Measurements were taken for ash layer, surface three depths (2–3, 7–8 14–16 cm). volumetric moisture content (SMC) deepest layers....
Abstract Mulching with forest residues has proved to be highly effective in reducing post‐fire soil losses at the plot scale. However, its effectiveness not been quantified application rates that are typically used operational land management (2–3 Mg ha ‐1 using straw), as well scales larger than 100 m 2 . The present study compared erosion for six convergent hillslopes or swales of 500 800 , three which were left untreated while other mulched immediately after fire shredded eucalypt bark a...
Abstract Context Olive groves are key features of Iberian Mediterranean landscapes. With the intensification olive grove production, some negative environmental impacts on soils must be considered to achieve farm sustainability. Objectives To estimate, theoretically and empirically, soil erosion in Alentejo (Portugal) considering different planting densities managements (i.e. conventional, integrated, organic), related loss Methods Soil was empirically calculated using sediment traps....
Abstract Soil phosphorus (P), which is essential for ecosystem functioning, undergoes notable changes after fire. However, the extent to fire characteristics affect P dynamics remains largely unknown. This study investigated impact of type (prescribed burning and natural wildfires) different levels severity on in Mediterranean soils. concentrations organic layers were strongly affected by but not type. Low did have any observable effect, while moderate increased soil 62% high decreased...
