Invasives Increases After Wind Turbine Construction

Invasives index values before and after turbine construction compared to surrounding control areas (top). Green indicates turbines with higher index values in the period after construction, and yellow indicates no change or lower invasive index values after construction. 5-year average Early Season Invasives index values for 1989–1993 (middle) and 2014–2018 (bottom) illustrating trends across the larger landscape. Green values indicate persistent yearly high NDVI values over each period (greater than 0.2).
