Sharp Hills Wind Farm: Assessment by Delta Waterfowl

As per your letter of engagement dated March 2, 2018, Delta Waterfowl has provided an assessment of the potential impacts of the Sharp Hills Wind Farm (SHWF) on breeding and migrating/staging (hereafter staging) waterfowl. We have reviewed all of the documents that you provided and have mapped the locations and extent of the proposed industrial wind development (Figure 1), proposed industrial wind turbine (IWT) locations in relation to wetlands in the region (Figure 2), breeding waterfowl densities (Figure 3), land-cover types (Figure 4), and a figure showing the waterfowl exclusion zones, avoidance zones (based on European literature – see below) and potential barrier effects if the proposed IWTs are constructed (Figure 5).

Based on our assessment, we have concerns that the proposed wind farm will adversely impact a number of avian (displacement and direct mortality) and bat (mortality) species. Unlike many species of passerines, birds of prey and bats that are killed by IWTs, waterfowl generally avoid industrial wind developments (Larsen and Madsen 2000; Desholm and Kahlert 2005, Stewart et al. 2005, Larsen and Guillemette 2007, Masden et al. 2009, Fijn et al. 2012, Rees 2012) which is problematic when IWTs are placed in and close to important waterfowl habitats, and/or across migratory or feeding flight corridors. This review pertains to the potential barrier effects and habitat loss (due to avoidance) that would be imposed on ducks, geese and swans if the proposed IWT development was constructed. It is our professional opinion that if the proposed industrial wind development is constructed, it will adversely impact breeding as well as spring and fall staging waterfowl. …
