Seasonal food habits of the endangered Indochinese leopard Panthera pardus delacouri in a protected area of North West Thailand

The Indochinese leopard Panthera pandits delacouri has experienced a sharp decline in numbers and distribution, especially in Thailand. We have analyzed its diet in Om Koi Wildlife Sanctuary of North West Thailand, where only wild prey species were present. Scats were collected during the dry-hot and the dry-cold seasons. The Indian muntjac appeared to be the staple of the leopard's diet, particularly in the dry-cold season, and consumed equally with the Indian wild boar in the dry-hot one. The occurrence of the Indochinese hog deer in the diet of the leopard in Om Koi represents the first detection record of this endangered species in North West Thailand, after being long extirpated. During the dry-hot season, poachers slashed and burnt portions of forest to flush game and to provide space for poppy fields. Muntjacs are sensitive to both forest tires and poaching, whereas Indian wild boar are resilient to disturbance, which may explain their alternation in diet.
