Role of Natal Habitat Preference Induction in Prairie-Grouse Translocation Success

Natal Habitat Preference Induction (NHPI) is the selection by a dispersing individual for habitat similar to where it was raised. It becomes particularly important when organisms are translocated, as the release site is often a different habitat type than the organism’s natal site. We related the role of NHPI to a lesser prairie-chicken (Tympanuchus pallidicinctus) project, translocating individuals from the Short-Grass Prairie/CRP Mosaic Ecoregion in northwestern Kansas (USA) to the U.S. Forest Service Cimarron and Comanche National Grasslands (CCNG) in the Sand Sagebrush Prairie Ecoregion of southwestern Kansas and southeastern Colorado (USA). Lesser prairie-chickens in the short-grass prairie select Conservation Reserve Program (CRP) grasslands, which is the predominantly used cover type in the primarily agricultural region. Both CRP grasslands and sand sagebrush (Artemisia filifolia) prairie are available at or near the CCNG, but native birds use primarily sand sagebrush prairie. From fall 2016 to summer 2017, a multi-agency effort translocated 110 lesser prairie-chickens (72 M, 38 F) equipped with VHF radio-collars from the Short-Grass Prairie/CRP Mosaic Ecoregion to the CCNG. Dispersal after release was variable and occasionally extensive ( = 14 km, SE = 1.7 km, range = 0.4 – 43 km). Although most translocated lesser prairie-chickens stayed near the study site, they appeared to select for the CRP/agricultural patchwork along the borders of the National Grasslands instead of the sand sagebrush prairie habitat. This suggests that natal habitat may affect the successful retention of translocated lesser prairie-chickens, which we intend to test further using GPS satellite transmitters in 2018.
