Final Report: Lesser Prairie-Chicken Survey − Kiowa and Rita Blanca National Grasslands, 2014
Final Report: Lesser Prairie-Chicken Survey − Kiowa and Rita Blanca National Grasslands, 2014 Project Manager: Angela Dwyer, Rocky Mountain Bird Observatory, 230 Cherry St., Fort Collins, CO 80521 ([email protected]) Project Director: David Hanni, Rocky Mountain Bird Observatory, 230 Cherry St., Fort Collins, CO 80521 ([email protected]) Introduction The Lesser Prairie-Chicken (Tympanuchus pallidicinctus) (LEPC) occupies grassland habitat consisting of sand sagebrush (Artemisia filifolia), sand shinnery oak (Quercus havardii) and mixed grass vegetation communities of the southern Great Plains. Since the 19th century, LEPC and the habitat upon which they depend has diminished across their historical range (Crawford and Bolen 1976, Taylor and Guthery 1980a), with recent estimates of current occupied range totaling approximately 17% of the estimated area of their historical range. Causes for this reduction in occupied range are primarily attributed to habitat loss and fragmentation (USFWS 2012). Habitat loss has been caused by conversion of native prairie to cropland (Bent 1932, Copelin 1963, Taylor and Guthery 1980) and long term fire suppression (Woodward et al. 2001) leading to tree invasion (Fuhlendorf et al. 2002). Grazing management practices would help improve habitat if managed to benefit LEPC. Heavily grazed fields that leave no residual vegetation for broods can be detrimental to LEPC (Sell 1979, Hunt and Best 2010). Habitat fragmentation has resulted from a combination of habitat loss and degradation caused by oil and gas development (Hunt 2004) and suspected effects of wind energy development (Pruett et al. 2009). The LEPC is not thought to occur in Kiowa and Rita Blanca National Grasslands (KRB) (Giesen 2003), however some parcels within the grasslands are managed for LEPC. -
