Wild boars use a wide range of habitats. Their invasive nature is gaining attention due to the complexity of its impact. The goal of this research is to analyze the impact of the wild boar on the chemical properties of soils in a natural and a post-fire forest in the Edough Forest Massif in Algeria. This study compares the impact of wild boar rooting on soil parameters to determine the functional role of the wild boar. The research was conducted during the winter of 2022. The study sites included a natural forest and a post-fire area. Rooting tracks were geolocated and soil samples were collected. The results show significant differences between rooted and control patches in the chemical parameters measured in the two environments. However, in the natural environment, significant differences were only noted for the calcium content and electrical conductivity. But in the post-fire environment, strong significant differences were observed for all measured parameters, suggesting that wild boars do not exert a noticeable soil homogenization effect on the soil properties. This research highlights the importance of understanding and managing the impact of wild boars in natural and post-fire forests on soil formation processes, the diversity of soil properties, and their magnitude.

野猪 (Sus scrofa) 生根对 Edough 森林地块（阿尔及利亚东北部）自然环境和火灾后环境中土壤化学性质的比较影响

野猪的栖息地范围广泛。由于其影响的复杂性，它们的侵入性正在引起人们的关注。这项研究的目的是分析野猪对阿尔及利亚埃多森林地块天然森林和火灾后森林土壤化学性质的影响。本研究比较了野猪扎根对土壤参数的影响，以确定野猪的功能作用。该研究于 2022 年冬季进行。研究地点包括天然林和火灾后区域。对根系进行地理定位并收集土壤样本。结果显示，在两种环境中测量的化学参数中，生根斑块和对照斑块之间存在显着差异。然而，在自然环境中，仅钙含量和电导率存在显着差异。但在火灾后环境中，所有测量参数均观察到强烈的显着差异，表明野猪并未对土壤性质产生明显的土壤均质化作用。这项研究强调了了解和管理自然森林和火灾后森林中野猪对土壤形成过程、土壤特性多样性及其影响程度的重要性。
