Wind Energy and Birds
The PLJV region encompasses some of the highest rated areas for wind energy development in the nation. As of January 2008, approximately 50 wind farms producing in excess of 4,000 megawatts of energy were in operation throughout the six-state region. While wind is an integral part of the nation's renewable energy portfolio, where wind farms are placed may have an impact on birds. In an effort to help the wind industry minimize impacts to birds, the PLJV conducted a spatial analysis of key wildlife habitats in the region and produced maps detailing where birds that may be sensitive to wind development may be found.
Lesser Prairie-Chicken
The Lesser Prairie-Chicken is a species unique to the region whose population has been declining for decades. The birds currently exist in only one tenth of their historic range. This range is coincident with where some of the greatest wind resources exist. Lesser Prairie-Chickens thrive best in large continuous patches of grassland with little disturbance. Research shows that the birds will avoid areas and abandon nesting sites near roads, buildings, wellheads, towers and power lines. To help industry professionals minimize impacts of wind development on the birds, the PLJV developed a spatial model to delineate areas that meet Lesser Prairie-Chicken habitat needs.

Wetlands and Bird Migration
Wetlands typically attract high concentrations of birds. In the PLJV region, where water is often scarce, wetlands like playas are primary gathering areas for birds. This is especially true during migration when thousands of birds will flock to a single wetland to feed and roost. Development of wind turbines, power lines and associated structures near wetlands may pose a risk of birds colliding with such structures. To help industry professionals minimize collisions and other potential impacts of wind development on wetland birds, the PLJV has identified areas of high wetland density throughout the region where such birds may be found.
