Effects of wind energy development on nesting ecology of greater prairie-chickens in fragmented grasslands.

McNew LB, Hunt LM, Gregory AJ, Wisely SM, Sandercock BK - Conserv. Biol. (2014)

Bottom Line: Proximity to turbines did not negatively affect nest site selection (β = 0.03, 95% CI = -1.2-1.3) or nest survival (β = -0.3, 95% CI = -0.6-0.1).Instead, nest site selection and survival were strongly related to vegetative cover and other local conditions determined by management for cattle production.Integration of our project results with previous reports of behavioral avoidance of oil and gas facilities by other species of prairie grouse suggests new avenues for research to mitigate impacts of energy development.

Relative probability (95% CI) of nest site selection (top) and daily survival rate of Greater Prairie-Chicken nests (bottom) versus distance of the nest to the nearest wind turbine during the preconstruction (2007–2008) and postconstruction periods (2009–2011) at the Meridian Way Wind Power Facility in northcentral Kansas. Parameter estimates were taken from factorial models with the effects of treatment period and distance to turbine.

fig03: Relative probability (95% CI) of nest site selection (top) and daily survival rate of Greater Prairie-Chicken nests (bottom) versus distance of the nest to the nearest wind turbine during the preconstruction (2007–2008) and postconstruction periods (2009–2011) at the Meridian Way Wind Power Facility in northcentral Kansas. Parameter estimates were taken from factorial models with the effects of treatment period and distance to turbine.

Mentions: Relative probability of use for nest site selection did not vary with distance to turbine during either the pre- or postconstruction periods (Fig. 3). The main factor driving nest site selection was the VOR, which was maximized at 3–6 dm in a quadratic function (Table 2, Fig. 4). Probability of use increased with grassland cover in the core use area and above a threshold distance of 300 m from forest patches. Conversely, probability of use was negatively affected in core use areas by forb cover at the nest, forest cover, and road density and in home range by proportion of agriculture and forest edge (Supporting Information).
