Fire enhances changes in phosphorus (P) dynamics determining potential post-fir...
Souza-Alonso, Pablo; Prats, Sergio; Merino, Agustin; Guiomar, Nuno; Guijarro, Mercedes; Madrigal, JavierSoil phosphorus (P), which is essential for ecosystem functioning, undergoes notable changes after fire. However, the extent to which fire characteristics affect P dynamics remains largely unknown. This study investigated the impact of type of fire (prescribed burning and natural wildfires) of different levels of severity on P dynamics in Mediterranean soils. Soil P concentrations in the organic layers were str...
Decision-making criteria to shape mulching techniques for fire-prone landscapes.
Petratou, Dafni; Nunes, João Pedro; Guimaraes, Maria Helena; Prats, SergioContext Wildfires have severe impacts on landscapes’ hydrological and sediment processes. They are linked to events such as flash floods and droughts, and high erosion rates which lead to loss of soil organic matter and detachment of seeds and seedlings. Mulching is an effective measure implemented directly after a fire to reduce soil erosion and increase soil water retention. However, its implementation has pr...
Biochar impacts on runoff and soil erosion by water: a systematic global scale ...
Gholamahmadi, Berhouz; Jeffery, Simon; Gonzalez-Pelayo, Oscar; Prats, Sergio; Bastos, Ana C.; Keizer, JacobBiochar application to soil has the potential to affect soil and vegetation properties that are key for the processes of runoff and soil erosion. However, both field and pot experiments show a vast range of effects, from strong reductions to strong increases in runoff and/or soil erosion. Therefore, this study aimed to quantify and interpret the impacts of biochar on runoff and soil erosion through the first sy...
Impacts of barley (Hordeum vulgare L.) straw mulch on post-fire soil erosion an...
González-Pelayo, Oscar; Prats, Sergio; Vieira, A.M.D.; Vieira, Diana; Maia, Paula; Keizer, JacobRural fires are now a major societal concern across the world, especially where fire regimes have (apparently) intensified in terms of burnt area, intensity and recurrency. Among the indirect fire effects, fire-enhanced runoff and erosion have been an important focus of post-fire land and water management, in particular through emergency stabilization of hillslopes using a range of erosion mitigation measures. ...
The effects of wildfire frequency on post-fire soil surface water dynamics.
González-Pelayo, Oscar; Prats, Sergio; van den Elsen, Eric; Malvar, Maruxa; Ritsema, Coen; Bautista, SusanaIncreasing wildfire frequency in the Mediterranean Basin could affect future plant-soil–water-dynamics. The capacity of soils to retain water is a key parameter affecting plant post-fire regeneration. Yet, few research has looked at how different soil properties related to water retention is affected by increasing wildfire frequency. This study aimed at understanding the relationship between wildfire frequency,...
Práticas para a gestão de recursos hídricos em bacias hidrográficas com históri...
Nunes, João; Parente, Joana; Benali, Akli; Nitzsche, N.; Prats, Sergio; Sá, Ana; Brito, Carlos; Dias, LuisOs incêndios rurais são um fenómeno recorrente em Portugal. Muitas vezes as cinzas produzidas por estes incêndios atingem as massas de água utilizadas para o abastecimento público, comprometendo a sua qualidade. Num exemplo recente, as cinzas resultantes dos incêndios de 2017 levaram à interrupção do abastecimento de água a algumas localidades, e à implementação de programas de monitorização adicional em outras...
Los incendios en la Red Natura 2000: situación, prevención y propuestas para un...
Almodovar; Brotons; Carrillo-Garcia; Carro; Cerdá; de la Cruz; Diaz-Delgado; Madrigal, Javier; Prats, Sergio; Rojo; Senra; et al.Contar con distintas herramientas de planificación territorial inconexas entre sí hace que se desaprovechen muchas de las sinergias potencialmente existentes entre ambas. Esto resulta más que evidente en el caso de la planificación forestal y la de conservación de la biodiversidad: planificaciones que operan sobre un mismo espacio físico, e incluso sobre unos mismos elementos y en la que se desaprovechan oportu...
Effects of forest residue mulching on organic matter and nutrient exports after...
Prats, SergioThe quick implementation of emergency stabilization measures is vital for minimizing post-fire soil erosion and the associated fertility loss. Mulching has proven to be highly effective in minimizing post-fire soil erosion, however few studies have investigated its impacts on organic matter (OM) and nutrient mobilization from burned forest areas. This study evaluates the effectiveness of forest residue mulching...
Decision-making criteria to shape mulching techniques for fire-prone landscapes
Petratou, Dapne; Nunes, J.P.; Guimarães, Maria; Prats, SergioContext Wildfires have severe impacts on landscapes’ hydrological and sediment processes. They are linked to events such as flash floods and droughts, and high erosion rates which lead to loss of soil organic matter and detachment of seeds and seedlings.

Effectiveness of community-based initiatives for mitigation of land degradation...
Prats, Sergio; Sierra-Abrain P.; Moraña-Fontan A.; Zas R.Local communities, informed about the main post-fire environmental threats, applied land restoration techniques after the 2017 Ponte Caldelas wildfire (Galicia, Spain). Volunteers crews, supervised by local researchers/technicians identified high-severity burned areas and applied: post-fire mulch by using corn mulch (chopped corn at a rate of 4 Mg ha−1), corn strip mulch (chopped corn on 1-m wide contourline-st...
