Bird and Bat Post-construction Monitoring at Noblesfontein Wind Energy Facility (Northern Cape)

In 2014 Bioinsight was appointed to conduct post-construction monitoring for birds and bats in and around this Wind Energy Facility in South Africa, using a wide variaty of methodologies.

Noblesfontein Wind Farm is located near the town of Victoria West in the Northern Cape Province, South Africa with a typical open Karoo habitat.  

In 2014 Bioinsight was appointed to conduct post-construction monitoring for birds and bats in and around the facility.  The purpose of this monitoring programme is to ultimately calculate the degree of area usage by all observed species (both birds and bats), and hence their risk of collision with the already-constructed wind turbines.  This is done through different methodologies, such as:

  •  365-day automatic and static bat monitoring (including monitoring at 60 meters height) 
  • Bat and bird monitoring along transects
  • Bat roost searches/inspections
  • Daily carcass searches around wind turbines
  • Vantage point monitoring for birds
  • Water body & nest monitoring, and so on.

Additionally, bias trials are also conducted in order to estimate fatality rates of birds and bats (as not all carcasses are always found in the field when conducting carcass searches).  These trials include searcher efficiency trials and carcass persistency trials.  

With all of this, Bioinsight hopes to aid in the implementation of relevant mitigation measures, if necessary, that will hopefully reduce fatalities to a minimal.
