The burning question: does fire affect habitat selection and forage preference of the black rhinoceros Diceros bicornis in East African savannahs?

Endangered species conservation requires information on how management activities influence habitat quality. The black rhinoceros (Diceros bicornus) is critically endangered and restricted to savannas representing ~5% of its historical range. Fire is used extensively in savanna, but little is known about how rhinos respond to burning. Our aim was to understand rhino responses to fire by studying habitat selection and foraging at multiple scales. We used resource selection functions and GPS locations of 31 rhinos from 2014-2016 to study rhino habitat use in Serengeti National Park, Tanzania. Rhino selectivity was quantified by comparing forage consumption to plant species availability in randomly sampled vegetation plots; rhino diets were subsequently verified through DNA-metabarcoding analysis of fecal samples. Rhino habitat use was a unimodal function of fire history, with highly occupied sites having fire frequencies of < 0.6 fires yr-1 and maximum occupancy occurring at a fire fre...
