Population status of the Hamadryas baboon in and around Simien Mountains National Park (SMNP), Ethiopia

A population of approximately 495 Hamadryas baboons, comprising adults, sub-adults, juveniles, and infants, was documented within Simien Mountains National Park (SMNP), Ethiopia. The study, conducted across both dry and wet seasons, revealed no significant seasonal changes in population dynamics, indicating that these baboons are primary residents of the park's southwestern, northern, and eastern regions. Age and gender diversity analysis showed a skewed sex ratio favoring females, with ratios of 1:1.65 for adults, 1:1.36 for sub-adults, and 1:1.46 for juveniles. This baseline study serves as a critical benchmark for future population tracking and conservation assessments in this extreme southwestern range of the species.
