Abstract

Overview

Inappropriate deployment of linear physical infrastructures, such as game fences, roads, electric power-lines, buildings, and phone masts can be detrimental to wild fauna. This study investigates the lesser-known ecological impacts of electromagnetic radiation (EMR) from phone masts on terrestrial birds and insects.

Methodology

Research was conducted in the Kafue National Park with ten 100m x 100m sample plots at three radial locations varying in EMR strength from a central phone mast. Various methods were used for data collection, including point counts for birds and various trapping and collection techniques for insects.

Findings

  • Data were analyzed using biological indices and ANOVA.
  • Significant reductions in wildlife diversity were noted with increasing EMR strengths.
  • Areas closer than 12 km to the phone mast and with EMR levels greater than 250 ± 20 μA/m were particularly affected.

Conclusion

The study suggests careful consideration of EMR levels in the deployment of wireless telecommunication infrastructures to minimize the negative ecological effects and preserve terrestrial biodiversity.
