Emissions of pollutants such as NOx, SOx, PM and CO can lower survivorship and increase susceptibility of affected wildlife to disease. The magnitude and unmitigated significance calculations are presented in the table below.

All tracks will be damped down to reduce risk of dust and this will be checked daily. With the above measures, the residual significance is presented in the following table.

Most impacted are acoustic communicators such as bird and bat species. The magnitude and unmitigated significance calculations are presented in the table below.

Minimize noise during sensitive months/ seasons (e.g bird breeding season) where possible: Houbara Bustard breeding seasons begins in mid-March and lasts until the end of July Egyptian Vulture’s breeding season occurs during summer months (June, July and August) The pre-construction biodiversity management program will include a Breeding Birds Protection Plan, which will provide the detailed timings, scope and methodology for pre-construction nest-searching in the appropriate seasons and locations; nests for Tier 1 species will be protected in-situ and no construction works shall be allowed throughout the duration of the breeding season within 500m of the nests. Noise barriers, if deemed feasible, shall be erected if required to ensure breeding birds are not impacted by excessive noise. In addition, the erection of turbines will not be undertaken for any WTGs within 750m of active Tier 1 nests and will be delayed until the nests have been vacated. Use of acoustic barriers, dampening, best available technology within construction methodology to reduce noise and vibration as much as possible. Intermittent noise is less desirable than continuous noise as it does not allow for habituation. With the above measures, the residual significance is presented in the following table.
