英文摘要	Dry soil had a high electric resistance, and thus, electric fences are not always efficient in arid regions. When an animal standing on the ground touches the electric line, an electric circuit is formed and the animal gets shocked. Not only dry soil but also snow reduces the efficacy of electric fences. This is because liquid water is conductive, but solid snow is an insulator. However, the conductance of frozen soil is not studied enough. This study aims to investigate whether frozen soil reduces the effectiveness of electric fences and determines the electrical resistance of frozen soil. Four electric fences were installed on the forest edge in Yamanashi Prefecture, central Japan. From May 2021 to March 2022, two sensor cameras per fence were used to detect probability of electrification and probability of intrusion into the fences. We treated from May to October 2021 and November 2021 to March 2022 as a non-frozen season (summer) and frozen season (winter), respectively. Results showed that in winter, the probability of electrification was decreased from 0.5 to 0.29 and the intrusion was increased from 0.03 to 0.07. When a pulsed current was applied, the electric conductance of frozen soil was reduced to 0.5% of that of the wet soil. Therefore, due to their reduced effectiveness in cold conditions, alternate grounding techniques for electric fences are required. For instance, the use of weed control sheet interwoven with stainless steel wire could be a practical solution.
