“…(%) AF: 0-1 9.7 9.7 5.3 12.7 The pre-fire potential fuel load was relatively high, but BF:1-5 6.9 6.8 7.4 11.0 this is still considerably less than estimates made from a shrub site in central Portugal, as would be expected given the lack of a competing tree canopy (Shakesby et al 2013). This change in the amount of pre-fire to postfire material represents an 85 % reduction in the combustible material on the forest floor.…”

“…Consequently, these areas would be expected to be at greater risk of erosion for longer during the post-fire 'window of disturbance' (Prosser and Williams 1998;Shakesby and Doerr 2006) when vegetation cover was more sparse than at the relatively wet Tresminas site where vegetation recovery is comparatively rapid. However, rapid vegetation recovery at the Tresminas site would mean that fuel reduction burns would need to be carried out on a more frequent basis in order to maintain a low combustible biomass on the forest floor (Shakesby et al 2013). The cumulative effect of repeated prescribed fires in Mediterranean forest plantations requires further research.…”

“…Shakesby et al (2015) observed that one year after prescribed fire the extractable potassium content of the soil increased compared to the pre-fire situation. In this study, however, two and thirty-six months later their content was less than the initial one.…”

“…As wildfire frequency in Mediterranean areas is predicted to increase in the future, prescribed (controlled) fire could be used routinely as a fuel management option to reduce wildfire hazard and its environmental impacts (Fernandes and Botelho 2003). The low fire severity associated with prescribed fire has reduced impacts on soil losses compared to less frequent but more severe wildfires (Shakesby et al 2015). However, repeated prescribed fires have been shown to cause progressive soil degradation (González-Pelayo et al 2010b).…”
