Effects of prescribed fire on surface soil in a Pinus pinaster plantation, nort...
Meira Castro, Ana C.; Shakesby, R. A.; Espinha Marques, J.; Doerr, S. H.; Meixedo, JP; Teixeira, J.; Chaminé, Helder I.In order to decrease the risk of severe wildfire, prescribed fire has recently been adopted in Portugal and elsewhere in the Mediterranean as a major tool for reducing the fuel load instead of manual or mechanical removal of vegetation. There has been some research into its impact on soils in shrublands and grasslands, but to date little research has been conducted in forested areas in the region. As a result, ...
Spatiotemporal variability of hydrologic soil properties and the implications f...
Ferreira, C. S. S.; Walsh, R. P. D.; Steenhuis, T. S.; Shakesby, R. A.; Nunes, J. P. N.; Coelho, C. O. A.; Ferreira, A. J. D.Planning of semi-urban developments is often hindered by a lack of knowledge on how changes in landuse affect catchment hydrological response. The temporal and spatial patterns of overland flow source areas and their connectivity in the landscape, particularly in a seasonal climate, remain comparatively poorly understood. This study investigates seasonal variations in factors influencing runoff response to rain...
Modelling runoff and erosion, and their mitigation, in burned Portuguese forest...
Vieira, D. C. S.; Prats, S. A.; Nunes, J. P.; Shakesby, R. A.; Coelho, C. O. A.; Keizer, J. J.The revised Morgan-Morgan-Finney (MMF) model was used as a modelling approach, which has performed reasonably well to estimate soil losses for burned areas in humid Mediterranean forests in Portugal, and NW Spain. Simple model enhancement approaches are applied to recently burned pine and eucalypt forested areas in north-central Portugal and to subsequent post-wildfire rehabilitation treatments. Model enhanceme...
Mitigating land degradation caused by wildfire: application of the PESERA model...
Esteves, T. C. J.; Kirkby, M. J.; Shakesby, R. A.; Ferreira, A. J. D.; Soares, J. A. A.; Irvine, B. J.; Ferreira, C. S. S.; Coelho, C. O. A.Wildfires represent an important agent of land degradation in temperate sub-humid ecosystems, including southern European Mediterranean countries. Identification of integrated conservation approaches that can reduce or prevent degradational impacts is the aim of the EU-funded DESIRE research program, part of which is concerned with quantifying the likely benefit of acceptable alternative conservation strategies...
