TABLE 1: ASSESSMENT AND REPORTING OF IMPACTS ON AVIFAUNAL SPECIES FOR ONSHORE WIND ENERGY GENERATION FACILITIES WHERE THE OUTPUT IS 20 MW OR MORE

 

1. General information

 

1.1. An applicant intending to undertake an activity identified in the scope of this protocol must undertake an Avifaunal Specialist Assessment based on the potential significance of the impact that the identified activity could have on bird species.

 

1.2. An Avifaunal Specialist Assessment is to be undertaken for all sensitivity ratings provided by the national web based environmental screening tool (screening tool)10, as the present level of knowledge on bird behaviour and species population precludes confident predictions on the sustainability of priority or threatened species nationally.

 

1.3. The information provided by the screening tool includes known nests, roosts, vulture restaurants and areas likely to support priority bird species including threatened or rare species, especially those that may be susceptible to wind energy development. Precautionary buffers to these sensitivities as well as to the specific feature have been added. The data is, however, unverified and incomplete and therefore these features and buffers are to be used only as a guide to assist to focus the Avifaunal Specialist Assessment.

 

VERY HIGH SENSITIVITY RATING - Very high sensitivity areas are likely to provide critical habitat for priority bird species11 sensitive to wind energy development12 and/or whose population is reliant on highly localized and unique roosting, nesting and /or foraging sites.

 

These areas are potentially unsuitable for development owing to there being recent confirmed evidence that the priority bird species are present.
2. The Avifaunal Specialist Assessment

 

2.1.The process for undertaking the Avifaunal Impact Assessment comprises of three phases:
(a) a reconnaissance study;
(b) the preparation of a pre-application avifaunal monitoring plan; and
(c) the undertaking of an avifaunal impact assessment and the preparation of a report.

 

2.2. All tasks of the Avifaunal Specialist Assessment must be undertaken by an avifauna specialist registered with the South African Council for Natural Scientific Professionals (SACNASP).

 

2 3.All tasks are to be undertaken on the site being submitted as the preferred site and on a control site located in accordance with the latest version of the Bird and Wind-Energy Best-Practice Guideline13, and must identify:
(a) the extent of the impact of the proposed development on priority bird species; and
(b) whether the proposed development will have an unacceptable impact on priority or threatened bird species.

 

2.4. The Avifaunal Specialist Assessment must be undertaken based on the results of a site specific Pre-Application Avifaunal Monitoring Plan that is informed by a Reconnaissance Study, as well as data collected over four seasons (i.e. summer, autumn, winter and spring) on the preferred site and the control site.

 

3. Reconnaissance Study

 

3.1.The Reconnaissance Study is to be based on a desktop study of relevant information as well as a 2 to 4-day on-site inspection of both sites.

 

3.2. The occurrence of target species is to be identified, including seasonality of occurrence and migratory patterns of the species.

 

3.3. The study must define the study area (avifaunal impact zone).

 

3.4.The study is to produce a site specific Pre-Application Avifaunal Monitoring Plan.

 

HIGH SENSITIVITY RATING - High sensitivity areas include:

(i) habitat likely to be of importance to priority bird species sensitive to wind energy developments, Critically Endangered, Endangered bird species and/or Vulnerable bird species; and
(ii) habitat likely to be of importance to endemic and/or restricted-range bird species that are susceptible to impacts from wind energy facilities. These areas are potentially sensitive for development.

MEDIUM SENSITIVITY RATING - Medium sensitivity areas have limited potential for supporting priority populations of threatened species that are susceptible to impacts from wind energy facilities.
4.Pre-application Avifaunal Monitoring Plan

 

4.1.The plan, as a minimum, must include14:
4.1.1. the study area and its characteristics which must be mapped including the extent, habitat, special features including topographical and water features, quarries, drainage lines, known breeding sites, existing uses of land, existing infrastructure such as power lines and roads, and existing operational wind energy facilities within 30km of the site;
4.1.2. target avifaunal species that are likely to occur on the preferred site and for which monitoring is required;
4.1.3. pre-application monitoring requirements for both the site as well as the control site, that must include the following:
4.1.3.1.the monitoring intervals including the number and duration of monitoring events which must be based on the latest version of the BirdLife South Africa Bird and Wind-Energy Best-Practice Guideline or a motivation provided for the deviation;
4.1.3.2.the location of monitoring points;
4.1.3.3.aspects to be monitored (for example, bird abundance and flight activity, presence of target species, proportion of flying time each target species spends at turbine rotor height, preferred flight paths, risk of identified target species to collision, areas for specific monitoring if any, etc.);
4.1.3.4.equipment to be used;
4.1.3.5.monitoring methodology for the abundance or activity monitoring and for direct observation or vantage point surveys, the latest version of the BirdLife South Africa Bird and Wind-Energy Best-Practice Guideline must be followed or a motivation provided for the deviation;
4.1.3.6.numbers of observers to be used; and
4.1.3.7.data to be captured including a pro-forma data capturing template consistent with that envisaged by the national bird monitoring database, once operational.

 

5. Implementation of the site specific Pre-Application Avifaunal Monitoring Plan

 

5.1.Monitoring according to the plan is to be carded out for a period of not less than four seasons.
5.2.Data on pre-application monitoring must be captured on the national bird monitoring database accessed at https://www.environment.gov.za/birddatabase, once operational.

 

6. Avifaunal Specialist Assessment

 

6.1.Based on the outcome of the reconnaissance study and the findings of the pre-application avifaunal monitoring, an Avifaunal Specialist Assessment must be undertaken. The assessment, as a minimum, must include the following aspects:
6.1.1.discussion on bird abundance and movement within the site;
6.1.2. discussion on presence of target or threatened species and their occurrence on the site at heights which could pose risks to collision;
6.1.3. assessment of risk of identified target species to collision including the expected fatality rates of the target species based on a suitable model commonly used for risk determination, per species and for the site;
6.1.4. identification and mapping where relevant, of any migratory or preferential bird routes or corridors;
6.1.5. where relevant, discussion on the risk of displacement;
6.1.6. where relevant, areas identified within the site as having a very high sensitivity for bird collision or displacement and in which the development of turbines should be avoided. These areas are to be mapped;
6.1.7. in areas where existing operational wind energy generation facilities have been identified within a 30km radius, a cumulative impact assessment must be undertaken which includes:
6.1.7.1.the fatality rates for target species at the wind energy generation facilities within a 10km radius;
6.1.7.2.the possible additional fatalities from the proposed wind energy generation facility for target species as well as general avifaunal species; and
6.1.7.3.a discussion on the possible cumulative impact of the proposed facility on regional populations of target species;

6.2.16.the outcomes of the post -construction monitoring, including data and specialists reports, must be uploaded onto the national bird monitoring database, to be accessed at https://www.environment.gov.za/birddatabase, once operational;
6.2.17.where required, proposed mitigation measures or any monitoring requirements for inclusion in the Environmental Management Programme (EMPr); and
6.2.18.a description of the assumptions made and any uncertainties or gaps in knowledge or data.

 

6.3.The findings of the Avifaunal Specialist Assessment must be incorporated into the Basic Assessment Report or the Environmental Impact Assessment Report, including the mitigation and monitoring measures as identified, which must be incorporated into the EMPr.

 

6.4.A signed copy of the Avifaunal Specialist Assessment must be appended to the Basic Assessment Report or Environmental Impact Assessment Report.

 

LOW SENSITIVITY RATING - Low sensitivity areas possibly do not support priority populations of threatened species that are susceptible to impacts from wind energy facilities. These areas are probably suitable for development.
