Camilty Wind Farm Level of Effect Slight Negligible Criteria issues may influence decision making if they lead to an increase in the overall adverse effects on a particular area or on a particular resource. These beneficial or adverse effects may be raised as local factors but are unlikely to be of critical importance in the decision making process. Nevertheless they are of relevance in enhancing the subsequent design of the scheme and consideration of mitigation or compensation measures. No effect or an effect which is beneath the level of perception, within normal bounds of variation or within the margin of forecasting error. Such effects are not normally considered by the decision maker. 12.2.45 The level of effect generated from Table 12.6 was then assessed against the likelihood of such predictions occurring, and the confidence level of the effect on a population, based on expert judgement and evidence from the existing literature. A scale of confidence, as recommended by IPCC (2005) can then be used: • Virtually certain: >99% probability of occurrence; • Very likely: >90% probability; • Likely: >66% probability; • About as likely as not: 33-66% probability; • Unlikely:

Camilty Wind Farm international), which corresponds with SNH policy (2006) which states that: “SNH will not normally object to a windfarm proposal on account of purely local impacts, if the impacts are not avoidable by reasonable means, if they do not result in any wider impact on the regional population, and provided the impacts do not affect populations protected within a designated site”. These conditions highlighted by SNH have been considered in the impact assessment process so that no potentially significant effects are omitted. 12.3 Baseline Information Sources of Data 12.3.1 The predicted effect of the proposed wind farm on VORs was assessed based on information in the published scientific literature, literature not subject to peer review and expert judgement. 12.3.2 Estimations of the possible extent and duration of effects are based on studies and key review papers in the scientific literature on ornithology and wind farms (e.g. Langston and Pullan, 2003; Drewitt and Langston, 2006). Disturbance and displacement distance ranges used in this assessment have been based on published reports and papers including Ruddock and Whitfield (2007) and Pearce-Higgins et al. (2009). Estimations of regional populations have been gathered and interpreted from most recent published reports such as Scottish Raptor Monitoring Scheme annual reports (e.g. Etheridge et al. 2012) and Forrester et al. (2007). Baseline Conditions Ecological Sensitivity Appraisal, Desk Study and Consultation 12.3.3 Between the initial Ecological Sensitivity Appraisal and the more detailed Desk Study several sites designated for their nature conservation interests were identified within up to 20 km from the Camilty site. Further details of those sites which are designated for their ornithological interests are provided below. 12.3.4 In terms of the ornithological value of the site itself this was generally considered to be low and was expected to support a reasonably limited variety of common bird species throughout the year. However, the Lothian and Borders Raptor Study Group identified that the woodland and immediately surrounding habitats have the potential to support goshawk and short-eared owl and that merlin, osprey, peregrine and long-eared owl had been recorded in the wider Camilty area in recent years. The appraisal also identified that overwintering waterfowl such as pink-footed geese may also pass over the site during migration or when commuting between nearby roosting and foraging grounds. 12.3.5 More recent consultation with Lothian and Borders Raptor Study Group revealed more detailed and up to date information about breeding raptors at this site. Further details of which is provided in the Confidential Ornithology Appendix. 12.3.6 Contact was also made with other nature conservation bodies to obtain any relevant data to inform the baseline situation of bird usage at Camilty.

Ecological Sensitivity Appraisal, Desk Study and Consultation<br />

12.3.3 Between the initial Ecological Sensitivity Appraisal and the more detailed Desk Study several<br />

sites designated <strong>for</strong> their nature conservation interests were identified within up to 20 km<br />

from the <strong>Camilty</strong> site. Further details of those sites which are designated <strong>for</strong> their<br />

ornithological interests are provided below.<br />

12.3.4 In terms of the ornithological value of the site itself this was generally considered to be low<br />

as pink-footed geese may also pass over the site during migration or when commuting<br />

between nearby roosting and <strong>for</strong>aging grounds.<br />

12.3.5 More recent consultation with Lothian and Borders Raptor Study Group revealed more<br />

detailed and up to date in<strong>for</strong>mation about breeding raptors at this site. Further details of<br />
