Wildfires severely affect forest ecosystems, degrading soil quality and reducing biodiversity. Post-fire management aims to mitigate these impacts and accelerate ecological recovery, but little research has explored their long-term effects on soil and plant diversity. Only a few studies have assessed post-fire management impacts beyond the short term. To fill this gap, this study provides evidence of the transient effects of mulching and logging after nearly a decade from fire and post-fire management. Changes in ground cover, soil properties and plant diversity due to post-fire management (mulching with straw and salvage logging) were measured 9 years after a severe wildfire in a Mediterranean pine forest. After burning, four groups of experimental plots were subjected to logging, mulching, logging and mulching, or left untreated (as a control). To assess these medium-term responses, surveys at plots were carried out to analyse soil physico-chemical and biochemical parameters together with plant diversity indexes across the four treatments. After 9 years, ground cover and most soil properties were no longer affected by the treatments. Only slight changes in beta-Glucosidase and microbial carbon as well as in phosphorous remained after this long time. The effects of both treatments on plant diversity became non-significant in comparison to burned but untreated soils. Overall, we conclude that these strategies are more effective for short-term recovery of burned forest ecosystems, while their impacts vanish several years after their implementation.
