Linking conservation actions to demography: grass height explains variation in greater sage-grouse nest survival

摘要: Conservation success often hinges on our ability to link demography with implementable management actions influence population growth (λ). Nest is demonstrated be important λ in greater sage-grouse Centrocercus urophasianus, an imperiled species the North American sagebrush-steppe. Enhancing this vital rate through represents opportunity increase bird numbers inside strongholds. We identified for grass height as action that can improve nest analysis of nests (n = 529) from a long-term study (2003–2007) Powder River Basin, southeast Montana and northeast Wyoming, USA. Average by area year varied (11.4–29.2 cm) but its positive effects survival were consistent among years areas differed absolute rates success. tested predictive models grouping output log-link analyses (2004–2006) into two bins probabilities <...
