Assessing the Efficiency of Two Silvicultural Approaches for Soil Erosion Mitigation Using a Novel Monitoring Apparatus

Abstract

Soil erosion and hydrogeological risk are critical phenomena gaining increased recognition within the scientific community. Although these occurrences are naturally occurring, human activities can exacerbate their impacts. For example, deforestation consistently amplifies soil erosion. This study examines two distinct forest management strategies aimed at addressing soil erosion: the Banded Standards Method (BSM) and the Scattered Standards Method (SSM). We conducted a field experiment in two test areas located in central Italy, with one area employing the BSM and the other implementing the SSM. Two soil erosion plots were established, representing prototypes of a novel erosion monitoring apparatus called the Natural Erosion Trap (NET), or Diabrosimeter, specifically designed for forest environments. At regular intervals, particularly after significant storm events, sediment and leaf litter accumulated within the erosion plots were collected, dried, and weighed to quantify erosion rates and assess the efficacy of the silvicultural methods under investigation. The results revealed a 30.72% reduction in the eroded material with BSM compared to SSM, underscoring BSM’s ability to mitigate potential hazards and preserve environmental integrity.
