Improper use, storage and handling can result in chemical spills and contamination of the soil and groundwater. Flora and fauna that come into contact may become ill or die. The magnitude and unmitigated significance calculations are presented in the table below.

Further, removal of vegetation may cause an increase in wind-driven soil erosion, leading to loss of native soils.

This in turn reduces the ability for vegetation recruitment and wildlife movement between habitat patches. Species with large home range requirements and migratory species in particular may be affected by fragmented habitat. Long-term fragmentation caused by physical barriers may also lead to a reduction in genetic exchange which is a concern for r-selected species with rapid generation turnover. The Wind Farm will not be fenced; therefore, there will be no physical barriers to movement. However, turbines may deter avifauna who exhibit macro-scale avoidance behaviour such as waterbirds; longer migratory movements can increase stress and lower survivorship of migrants that expend more energy to navigate around wind farms. Migratory raptors do not exhibit macro-avoidance behaviour; (in fact, this is the reason that migratory raptors are at high risk for turbine collision); thus, habitat fragmentation from the presence of migratory movement barriers is not considered to apply to raptors. The magnitude and unmitigated significance calculations are presented in the table below. The magnitude of the potential impact for endangered birds has been determined to be negligible given that the project site does not represent a migratory corridor bottleneck for waterbirds as evidenced by survey results which did not record the presence of any endangered waterbirds.
