Aerial Surveys for Prairie Grouse Leks: Detectability, Disturbance Response, and

Prairie grouse (Tympanuchus and Centrocercus spp.) once occupied wide expanses of North American grass and shrub habitats. In the last three decades, prairie grouse populations have exhibited precipitous declines, often because of altered land use practices. There is a need to develop new research and management techniques to facilitate prairie grouse conservation efforts. We evaluated aerial survey capabilities to assist in the management of lesser prairie-chickens (Tympanuchus pallidicinctus; [LPC]). Our objectives were to determine the most efficient aircraft type and flight parameters...
