The Indian Crested Porcupine's use of habitat and tree species was studied in Sariska National Park of Rajasthan. Results show a widespread incidence of debarking Acacia catechu, A. leucophloea, Butea monosperma and Zizyphus mauritiana trees. Anogeissus pendula, Balanites aegyptiaca, Boswellia serrata and Capparis decidua were not debarked at all. Habitat selection was influenced by the presence or absence of these species. Acacia catechu was debarked more, while A. leucophloea and Butea monosperma were debarked less than the proportion available. Zizyphus mauritiana was consumed in proportion of availability. Similar low preferences were shown for small girth classes. Tree mortality due to debarking was found to be extremely low, and does not warrant any active management intervention.
