英文摘要

Wildfire has historically been an alteration factor in Mediterranean basins. Despite Mediterranean ecosystems’ high resilience, wildfire accelerates erosion and degradation processes, and also affects soil functionality by affecting nutrient cycles and soil structure. In semi-arid Mediterranean basins, check dams are usually built in gullies and channels after fire as a measure against soil erosion. Although check dams have proven efficient action to reduce erosion rates, studies about how they affect soil functionality are lacking. Our approach focuses on how soil functionality, defined as a combination of physico-chemical and biological indicators, is locally affected by check dam construction and the evolution of this effect over time. Soils were sampled in eight check dams in two semi-arid areas at SE Spain, which were affected by wildfire in 2012 and 2016.


The study findings reveal that by altering sediments cycle and transport, check dams influence soil’s main physico-chemical and biochemical characteristics. Significant differences were found between check dam-affected zones and the control ones for many indicators such as organic matter content, electrical conductivity or enzymatic activity. According to the ANOVA results, interaction between check dams influence and lime after fire, was a crucial factor.


PCA results clearly showed check-dams influence on soil functionality. (C) 2018 Elsevier B.V. All rights reserved.
